I have a cell based NSOutlineView in that I have sub classed the NSTextfieldCell and I had written following code.
-(void)drawWithFrame:(NSRect)cellFrame inView:(NSView *)controlView {
// A single cell instance is used to render every row, so we can't store the
// custom view here
NSRect bgFrame = cellFrame;
bgFrame.size.width = bgFrame.size.width + bgFrame.origin.x + 3;
bgFrame.origin.x = 0;
if ([self isHighlighted])
{
[[NSColor blackColor] set];
NSRectFill(bgFrame);
}
else
{
NSGradient *gradient = [[NSGradient alloc] initWithStartingColor:[NSColor whiteColor] endingColor:[NSColor lightGrayColor]];
[gradient drawInRect:bgFrame angle:90];
}
[controller showViews:controlView frame:bgFrame highlight:[self isHighlighted] && !isEditing];
}
In View controller
-(void)showViews:(NSView*)parent frame:(NSRect)cellFrame highlight:(BOOL)highlight
{
NSView* nestedView;
nestedView = menu100;
[nestedView setFrame: cellFrame];
if ([nestedView superview] != parent)
{
[nestedView prepareContentInRect:[nestedView visibleRect]];
[parent addSubview: nestedView];
}
}
nestedView = menu100; menu100 is a `NSView` with `NSOutlineview`
menu100 view
In NSOutlineView
- (void)outlineView:(NSOutlineView *)outlineView willDisplayCell:(id)cell forTableColumn:(NSTableColumn *)tableColumn item:(id)item {
if ([item isKindOfClass:[NSDictionary class]]) {
[cell setBackgroundColor:[NSColor keyboardFocusIndicatorColor]];
}
else
{
if (item!=nil) {
CustomCellController* cellCtrl = [cellViewControllers objectForKey:item];
if (!cellCtrl)
{
cellCtrl = [[CustomCellController alloc] initWithMenu:item];
[cellViewControllers setObject:cellCtrl forKey:item];
}
CustomCell* mycell = cell;
[mycell setController:cellCtrl];
}
}
}
now the view is look like this
Now when I click on child outline view it become flipped.
The above code is working in 10.8 but it is get flipped in 10.9. I am become mad on this. Can any one give suggestion to get rid of this in 10.9.

I am using a Toggle button in XIB,
in AwakeFromNib :I set title and BG image of the button.
Code works very well till OSX 10.10.5 and below but on higher versions when I click on button the text gets removed.
Set attributed Title
[self.deleteButton setWantsLayer:YES];
self.deleteButton.layer.backgroundColor = [self setButtonBGColor];
[self setButtonTitleFor:self.deleteButton
toString:#"Delete"];
[self.deleteButton setLayerContentsRedrawPolicy:NSViewLayerContentsRedrawOnSetNeedsDisplay];
- (void)setButtonTitleFor:(NSButton*)button toString:(NSString*)title
{
NSAttributedString *attrString = [self getAttributedStringForString:title];
[button setAttributedTitle:attrString];
}
Any idea hat should be done.
So finally got it right
Subclassing NSButtonCell helped me out
RPButtonTextTopCell.h
#interface RPButtonTextTopCell : NSButtonCell
#end
RPButtonTextTopCell.m
#implementation RPButtonTextTopCell
-(id) init
{
self = [super init];
if (self) {
}
return self;
}
-(id) initWithCoder:(NSCoder *)decoder
{
return [super initWithCoder:decoder];
}
-(id) initTextCell:(NSString *)string
{
return [super initTextCell:string];
}
-(NSRect)titleRectForBounds:(NSRect)theRect
{
NSRect titleFrame = [super titleRectForBounds:theRect];
NSSize titleSize = [[self attributedStringValue] size];
titleFrame.origin.y = (theRect.origin.y - (theRect.size.height-titleSize.height)*0.5) + 5;
return titleFrame;
}
#end
Utilizing This Custom Class
RPButtonTextTopCell *deleteCell = [[RPButtonTextTopCell alloc] init];
deleteCell.backgroundColor = [self setNSButtonBGColor];
[self.deleteButton setCell:deleteCell];
[self setButtonTitleFor:self.deleteButton
toString:#"Delete"];
[self.deleteButton setAction:#selector(deleteButtonClicked:)];
[self.deleteButton setTarget:self];
and its solved....
I have a question about UIPickerView.
I build the UIPickerView , the picker have popup normal,
but I need dismiss the pickerview when I click the screen.
But When I click the screen , the picker have dismiss, but the backgrouond gray color view(?) still remain.
Like this:
my part code is here
dataAry = [[NSArray alloc] initWithObjects:#"test1",#"test2",#"test3",#"test4",#"test5", nil] ;
pickerView = [[UIPickerView alloc] initWithFrame:CGRectZero];
pickerView.delegate = self;
pickerView.dataSource = self;
pickerView.showsSelectionIndicator = true;
_myTF.inputView = pickerView;
UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(hideThePicker)];
tapGesture.delegate = self;
tapGesture.cancelsTouchesInView = NO;
[self.view addGestureRecognizer:tapGesture];
}
-(IBAction)hideThePicker {
pickerView.frame = CGRectMake(0, 480, 320, 260);
}
- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView
{
return 1;
}
- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger) row forComponent:(NSInteger)component
{
return dataAry[row];
}
- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent: (NSInteger)component
{
return [dataAry count];
}
- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent: (NSInteger)component
{
NSLog(#"dataAry selected:%ld", row);
}
Have any one teach me how can I totally dismiss pickerview when I touch the screen?
thank you very much.
my test pickerview totally code in here:
git: https://github.com/dickfala/pickerViewTest.git
Why don't you use -
-(IBAction)hideThePicker {
[_myTF resignFirstResponder];
pickerView.hidden = YES;
}
you can hide the UIPickerView just by using its 'hidden' property.
EDIT-
Check updated answer above, you have to resign the text field responder as well.
I am trying to figure out how to do a source list 100% in code. I've been hacking away at SideBar demo and various SO questions/answers and have gotten close, but not quite there. I've copied my code below, this seems to work in that it does build a view, with 3 empty cells I can select. What I can't quite figure out is how to get my text to show up in those cells. I will ultimately replace that with my own view, but I'd settle for the stock rendering to work for now..
In my controller:
#implementation SourceListController {
NSScrollView *_scrollView;
NSOutlineView *_sourceList;
SourceListDataSource *_sourceListDataSource;
}
- (void)loadView {
_scrollView = [[NSScrollView alloc] init];
_sourceList = [[NSOutlineView alloc] init];
_sourceListDataSource = [[SourceListDataSource alloc] init];
[_sourceList setSelectionHighlightStyle:NSTableViewSelectionHighlightStyleSourceList];
NSTableColumn *c = [[NSTableColumn alloc] initWithIdentifier: #"Column"];
[c setEditable: NO];
[c setMinWidth: 150.0];
[_sourceList addTableColumn: c];
[_sourceList setOutlineTableColumn:c];
[_sourceList setDelegate:_sourceListDataSource];
[_sourceList setDataSource:_sourceListDataSource];
[_scrollView setDocumentView:_sourceList];
[_scrollView setHasVerticalScroller:YES];
[_sourceList reloadData];
NSLog(_sourceList.dataSource == _sourceListDataSource ? #"YES" : #"NO");
self.view = _scrollView;
}
And in my data source/delegate:
#implementation SourceListDataSource {
}
- (NSInteger)outlineView:(NSOutlineView *)outlineView numberOfChildrenOfItem:(id)item {
return item == nil ? 3 : 0;
}
- (id)outlineView:(NSOutlineView *)outlineView child:(NSInteger)index ofItem:(id)item {
return [NSObject new];
}
- (BOOL)outlineView:(NSOutlineView *)outlineView isItemExpandable:(id)item {
return item == nil;
}
- (NSView *)outlineView:(NSOutlineView *)outlineView viewForTableColumn:(NSTableColumn *)tableColumn item:(id)item {
NSLog(#"Here %f", tableColumn.width);
NSTableCellView *result = [[NSTableCellView alloc] init];
NSTextField *textField = [[NSTextField alloc] init];
[textField setStringValue:#"Test"];
[result addSubview:textField];
return result;
}
UPDATE: Further digging tells me viewForTableColumn doesn't even get called.. I am stumped as to why..
UPDATE 2: Figured out that it was the missing column and outlineTableColumn leading to not calling the delegate method. I fixed that and updated the code, but still no text shows up.
Your delegate method needs changes, it won't work that way, and also doesn't make use of the new caching methods for views. Mostly, use the NSTableCellView.textFieldproperty instead of adding your own NSTextFieldwithout frame and frame constraints. So, the code that should work looks like this:
- (NSView *)outlineView:(NSOutlineView *)outlineView viewForTableColumn:(NSTableColumn *)tableColumn item:(id)item {
NSTableCellView *result = [outline makeViewWithIdentifier:#"MyView" owner:self];
if (result == nil) {
// Create the new NSTextField with a frame of the {0,0} with the width of the table.
// Note that the height of the frame is not really relevant, because the row height will modify the height.
CGRect myRect = CGRectMake(0,0,outlineView.framesize.width,0);
result = [[NSTableCellView alloc] initWithFrame:myRect];
// The identifier of the view instance is set to MyView.
// This allows the cell to be reused.
result.identifier = #"MyView";
}
result.textField.stringValue = #"Test";
return result;
}
All the above typed in SO.
I'm making a little server app for OS X and I'm using an NSTextView to log some info about connected clients.
Whenever I need to log something I'm appending the new message to the text of the NSTextView this way:
- (void)logMessage:(NSString *)message
{
if (message) {
self.textView.string = [self.textView.string stringByAppendingFormat:#"%#\n",message];
}
}
After this I'd like the NSTextField (or maybe I should say the NSClipView that contains it) to scroll down to show the last line of its text (obviously it should scroll only if the last line is not visible yet, in fact if then new line is the first line I log it is already on the screen so there is no need to scroll down).
How can I do that programmatically?
Found solution:
- (void)logMessage:(NSString *)message
{
if (message) {
[self appendMessage:message];
}
}
- (void)appendMessage:(NSString *)message
{
NSString *messageWithNewLine = [message stringByAppendingString:#"\n"];
// Smart Scrolling
BOOL scroll = (NSMaxY(self.textView.visibleRect) == NSMaxY(self.textView.bounds));
// Append string to textview
[self.textView.textStorage appendAttributedString:[[NSAttributedString alloc]initWithString:messageWithNewLine]];
if (scroll) // Scroll to end of the textview contents
[self.textView scrollRangeToVisible: NSMakeRange(self.textView.string.length, 0)];
}
As of OS 10.6 it's as simple as nsTextView.scrollToEndOfDocument(self).
Swift 4 + 5
let smartScroll = self.textView.visibleRect.maxY == self.textView.bounds.maxY
self.textView.textStorage?.append("new text")
if smartScroll{
self.textView.scrollToEndOfDocument(self)
}
I've been messing with this for a while, because I couldn't get it to work reliably. I've finally gotten my code working, so I'd like to post it as a reply.
My solution allows you to scroll manually, while output is being added to the view. As soon as you scroll to the absolute bottom of the NSTextView, the automatic scrolling will resume (if enabled, that is).
First a category to #import this only when needed...
FSScrollToBottomExtensions.h:
#interface NSView (FSScrollToBottomExtensions)
- (float)distanceToBottom;
- (BOOL)isAtBottom;
- (void)scrollToBottom;
#end
FSScrollToBottomExtensions.m:
#implementation NSView (FSScrollToBottomExtensions)
- (float)distanceToBottom
{
NSRect visRect;
NSRect boundsRect;
visRect = [self visibleRect];
boundsRect = [self bounds];
return(NSMaxY(visRect) - NSMaxY(boundsRect));
}
// Apple's suggestion did not work for me.
- (BOOL)isAtBottom
{
return([self distanceToBottom] == 0.0);
}
// The scrollToBottom method provided by Apple seems unreliable, so I wrote this one
- (void)scrollToBottom
{
NSPoint pt;
id scrollView;
id clipView;
pt.x = 0;
pt.y = 100000000000.0;
scrollView = [self enclosingScrollView];
clipView = [scrollView contentView];
pt = [clipView constrainScrollPoint:pt];
[clipView scrollToPoint:pt];
[scrollView reflectScrolledClipView:clipView];
}
#end
... create yourself an "OutputView", which is a subclass of NSTextView:
FSOutputView.h:
#interface FSOutputView : NSTextView
{
BOOL scrollToBottomPending;
}
FSOutputView.m:
#implementation FSOutputView
- (id)setup
{
...
return(self);
}
- (id)initWithCoder:(NSCoder *)aCoder
{
return([[super initWithCoder:aCoder] setup]);
}
- (id)initWithFrame:(NSRect)aFrame textContainer:(NSTextContainer *)aTextContainer
{
return([[super initWithFrame:aFrame textContainer:aTextContainer] setup]);
}
- (void)dealloc
{
[[NSNotificationCenter defaultCenter] removeObserver:self];
[super dealloc];
}
- (void)awakeFromNib
{
NSNotificationCenter *notificationCenter;
NSView *view;
// viewBoundsDidChange catches scrolling that happens when the caret
// moves, and scrolling caused by pressing the scrollbar arrows.
view = [self superview];
[notificationCenter addObserver:self
selector:#selector(viewBoundsDidChangeNotification:)
name:NSViewBoundsDidChangeNotification object:view];
[view setPostsBoundsChangedNotifications:YES];
// viewFrameDidChange catches scrolling that happens because text
// is inserted or deleted.
// it also catches situations, where window resizing causes changes.
[notificationCenter addObserver:self
selector:#selector(viewFrameDidChangeNotification:)
name:NSViewFrameDidChangeNotification object:self];
[self setPostsFrameChangedNotifications:YES];
}
- (void)handleScrollToBottom
{
if(scrollToBottomPending)
{
scrollToBottomPending = NO;
[self scrollToBottom];
}
}
- (void)viewBoundsDidChangeNotification:(NSNotification *)aNotification
{
[self handleScrollToBottom];
}
- (void)viewFrameDidChangeNotification:(NSNotification *)aNotification
{
[self handleScrollToBottom];
}
- (void)outputAttributedString:(NSAttributedString *)aAttributedString
flags:(int)aFlags
{
NSRange range;
BOOL wasAtBottom;
if(aAttributedString)
{
wasAtBottom = [self isAtBottom];
range = [self selectedRange];
if(aFlags & FSAppendString)
{
range = NSMakeRange([[self textStorage] length], 0);
}
if([self shouldChangeTextInRange:range
replacementString:[aAttributedString string]])
{
[[self textStorage] beginEditing];
[[self textStorage] replaceCharactersInRange:range
withAttributedString:aAttributedString];
[[self textStorage] endEditing];
}
range.location += [aAttributedString length];
range.length = 0;
if(!(aFlags & FSAppendString))
{
[self setSelectedRange:range];
}
if(wasAtBottom || (aFlags & FSForceScroll))
{
scrollToBottomPending = YES;
}
}
}
#end
... You can add a few more convenience methods to this class (I've stripped it down), so that you can output a formatted string.
- (void)outputString:(NSString *)aFormatString arguments:(va_list)aArguments attributeKey:(NSString *)aKey flags:(int)aFlags
{
NSMutableAttributedString *str;
str = [... generate attributed string from parameters ...];
[self outputAttributedString:str flags:aFlags];
}
- (void)outputLineWithFormat:(NSString *)aFormatString, ...
{
va_list args;
va_start(args, aFormatString);
[self outputString:aFormatString arguments:args attributeKey:NULL flags:FSAddNewLine];
va_end(args);
}
I have some customised NSTextView and custom input method so my option was to use:
self.scrollView.contentView.scroll(NSPoint(x: 1, y: self.textView.frame.size.height))
Im having this problem for weeks already. because my app needs a function that will create a UITextfield, undo, and delete the UITexfield. my code create textfield anywhere on the view when you tap it. and it also can undo the last textfield that been created when pressed button undo, it can be move, scale, rotate also, but after i created another new textfield, the old one was been attached to the view. that is why when i long pressed the old textfield, it can be deleted only the new one that was been created can be delete. what will i do how to make that old textfield deleted?here my code.

You are using wrong method DoAction as selector, instead use LongPressgesture method
Update your code like following:
- (void)viewDidLoad{
[super viewDidLoad];
textfieldform = [[NSMutableArray alloc] init];
textField1 = ... // Initialize textfield
UILongPressGestureRecognizer *holdRecognizer = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:#selector(LongPressgesture:)];
[holdRecognizer setMinimumPressDuration:2];
[holdRecognizer setDelegate:self];
[textField1 addGestureRecognizer:holdRecognizer];
}
- (void)LongPressgesture:(UILongPressGestureRecognizer *)recognizer
{
if (recognizer.state == UIGestureRecognizerStateEnded) {
//[textfieldform removeObject: recognizer.view];
[recognizer.view removeFromSuperview];
NSLog(#"Long press Ended .................");
}
else {
NSLog(#"Long press detected .....................");
}
}
