Is there a way to tell OS X to automatically style/tint a NSToolbarItem?
I've added an "Image Toolbar Item" via IB/Xcode and set the icon to a black PDF as described in the documentation.
However, my result does not resemble that of, for instance, the App Store:
I'm looking for something akin to what the TabBar in iOS does by default.
I'm new to OS X development... So any guidance would be appriciated!
Images need to be made template'd in order to get the correct styling (such as the engraved & blue styling).
This can be done in code with -[NSImage setTemplate:] or by having your image names end with "Template" (requiring no code changes).
To get the blue styling specifically, you have to set a borderless NSButton as the custom view of the toolbar item (rather than it being a standard item). That button has to have a type that results in it showing its state (e.g. a Round-Textured Toggle button), and when it has an On state, it will get then blue styling.
If you're trying to create a tinted toolbar item in code, This is how I did it. Create the correct type of button NSButtonTypeToggle then set the buttons properties, then add the button to the toolbar item's custom view and finally the toolbar item is returned.
- (NSToolbarItem *)toolbar:(NSToolbar *)toolbar itemForItemIdentifier:(NSToolbarItemIdentifier)itemIdentifier willBeInsertedIntoToolbar:(BOOL)flag {
// create toolbar items
NSToolbarItem *toolbarItem = [[NSToolbarItem alloc] initWithItemIdentifier:itemIdentifier];
toolbarItem.label = #"title";
NSImage *iconImage = [NSImage imageNamed:NSImageNameColumnViewTemplate];
NSButton *button = [[NSButton alloc] initWithFrame:NSMakeRect(0, 0, 40.0, 40.0)];
button.title = #"";
button.image = iconImage;
[button setButtonType:NSButtonTypeToggle];
button.bezelStyle = NSBezelStyleTexturedRounded;
button.action = #selector(toggleColumnView:);
[toolbarItem setView:button];
return toolbarItem;
}

How to change image by click on that image in Iphone.Instead of button click I want to click on image.Which method can I use UIImageView.
Use a button and make your picture the picture for the button. You can do all this in Storyboard and then right click the button and drag to the view you want to go to. It should work just like that.
After you drag the button to the storyboard go to the property inspector. Make the button a custom button in the drop down list and then use the image field to select your image. You will need to size the button correctly and set the fill property to "size to fit." the other button behaviors are all customizable if you don't want normal button behavior, i.e. visually reacting to a touch.
This can be done by using touchevents also
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
if ([[touches anyObject] view] == self.m_ImageViewObjectName) {
//Here you can change the image of UIImageView
}
}
You have to set tapRecognizer for your ImageView. It'll detect tap on your ImageView and call the method -clickEventOnImage.
UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc]
initWithTarget:self action:#selector(clickEventOnImage:)];
[tapRecognizer setNumberOfTouchesRequired:1];
[tapRecognizer setDelegate:self];
//Don't forget to set the userInteractionEnabled to YES, by default It's NO.
myImageView.userInteractionEnabled = YES;
[myImageView addGestureRecognizer:tapRecognizer];
Add your clickEventOnImage: will look like this :
-(void) clickEventOnImage:(id) sender
{
[myImageView setImage:[UIImage imageNamed: #"myNewImageName.png"]];
}
In my OS X app, using Interface Builder, I have a window that looks like this:
I'd like to add a button to the right-hand side, to achieve this:
If this is possible, how can I do it?
It is not possible to do with Interface Builder, however you can get it done with little bit of coding :
NSButton *closeButton = [window standardWindowButton:NSWindowCloseButton]; // Get the existing close button of the window. Check documentation for the other window buttons.
NSView *titleBarView = closeButton.superview; // Get the view that encloses that standard window buttons.
NSButton *myButton = …; // Create custom button to be added to the title bar.
myButton.frame = …; // Set the appropriate frame for your button. Use titleBarView.bounds to determine the bounding rect of the view that encloses the standard window buttons.
[titleBarView addSubview:myButton]; // Add the custom button to the title bar.
Swift 2.2 and Auto Layout, Create an "OK" button to the right of the title bar:
let myButton = NSButton()
myButton.title = "OK"
myButton.bezelStyle = .RoundedBezelStyle
let titleBarView = window!.standardWindowButton(.CloseButton)!.superview!
titleBarView.addSubview(myButton)
myButton.translatesAutoresizingMaskIntoConstraints = false
titleBarView.addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("H:[myButton]-2-|", options: [], metrics: nil, views: ["myButton": myButton]))
titleBarView.addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("V:|-1-[myButton]-3-|", options: [], metrics: nil, views: ["myButton": myButton]))
With auto layout, you don't need to hard-code button's frame. And it is always on the right of the title bar even you resize the window.
Mountain Lion offers a built-in sharing button that reveals a menu of sharing services appropriate for the app:
How can I insert it in my app?
To add the share button on Mountain Lion:
1) Add a NSButton called, for example, shareButton.
2) Add the standard image for this button:
[shareButton setImage:[NSImage imageNamed:NSImageNameShareTemplate]];
[shareButton sendActionOn:NSLeftMouseDownMask];
3) Into the "on click action", present the NSSharingServicePicker:
NSSharingServicePicker *sharingServicePicker = [[NSSharingServicePicker alloc] initWithItems:urls];
sharingServicePicker.delegate = self;
[sharingServicePicker showRelativeToRect:[sender bounds]
ofView:sender
preferredEdge:NSMinYEdge];
4) Eventually, implement the NSSharingServicePickerDelegate methods to customize the picker’s available services.
In Swift, I've used this:
extension NSSharingService {
class func shareContent ( content: [AnyObject], button: NSButton ) {
let sharingServicePicker = NSSharingServicePicker (items: content )
sharingServicePicker.showRelativeToRect(button.bounds, ofView: button, preferredEdge: NSRectEdge.MaxY)
}
}
Note that if you're trying to add this button via Interface Builder:
Select the button
Switch to Attributes inspector
Delete the button Title
Insert: NSShareTemplate as the Image name.
It doesn't look right to me in XCode, but works fine when run.
PS - This appears to be a case where you need to use the System Icon string value (NSShareTemplate) instead of the constant (NSImageNameShareTemplate).
In the HIG's example of how to use disclosure triangles, it shows a label directly to the right of the triangle.
However, when I throw one of these onto my view in Interface Builder, the text is centered on top of the triangle. I've searched the NSButton API docs, and poked at everything I can find in IB, but nothing I try will put the text to the right of the triangle. What am I missing?
What I generally do is use 2 buttons: one disclosure button and another button for the label:
While you can use a text field for the label, I prefer using a button and setting the button to call performClick: on the disclosure triangle. This makes for a much larger target area to be able to click on than a tiny triangle. (Users with trackpads will thank you).
To set up the button, change it so it looks like this:
Then set its action:
I'm not sure if there's an actual way to get the button to show both properly (without subclassing I mean), since I've generally just used separate items to give the effect. (I just checked and there is indeed a Carbon disclosure control that has both the triangle and the label built-in).
The Carbon control has the right idea where clicking on the label will automatically trigger the control. In some places (notably the re-written Cocoa Finder), you can see that you don't get that behavior for free (unless you use a button like I've shown). I still have an open bug on that one (rdar://6828042): BugID 6828042: 10.6 (10A335) Finder: Inspector's disclsr. triangle's text label not toggleable". ;-)
Have you tried just using a triangle and using a separate label?
The disclosure triangle widget is drawn by the button's bezel, centered in the available space. To create a disclosure triangle button which also has a title, you just need to subclass NSButtonCell and make sure the bezel is restricted to the left side of the button and that the title avoids the bezel. Then add your button in IB, expand it and set your title, and set the class of the cell. Unfortunately, IB won't know how to display your subclass and will put the triangle in the middle of the button. Just make sure it's big enough.
In Objective-C:
#interface TitledDisclosureTriangleButtonCell : NSButtonCell
#end
#define TRIANGLE_PADDING 15.f
#implementation TitledDisclosureTriangleButtonCell
- (NSRect)titleRectForBounds:(NSRect)theRect
{
NSRect titleRect = [super titleRectForBounds:theRect];
titleRect.origin.x = TRIANGLE_PADDING;
titleRect.size.width = NSWidth(titleRect) - TRIANGLE_PADDING;
return titleRect;
}
- (void)drawBezelWithFrame:(NSRect)frame inView:(NSView *)controlView
{
NSRect bezelFrame = frame;
bezelFrame.size.width = TRIANGLE_PADDING;
[super drawBezelWithFrame:bezelFrame inView:controlView];
}
#end
And in Swift:
let TRIANGLE_PADDING: CGFloat = 15
class TitledDisclosureTriangleButtonCell: NSButtonCell
{
override func titleRectForBounds(theRect: NSRect) -> NSRect {
var titleRect = super.titleRectForBounds(theRect)
titleRect.origin.x = TRIANGLE_PADDING
titleRect.size.width = titleRect.size.width - TRIANGLE_PADDING
return titleRect
}
override func drawBezelWithFrame(frame: NSRect, inView controlView: NSView) {
var bezelFrame = frame
bezelFrame.size.width = TRIANGLE_PADDING
super.drawBezelWithFrame(bezelFrame, inView: controlView)
}
}
I am trying to recreate the nice textured buttons like Finder, Safari and Transmission have in their toolbar. First I started by just dragging in a "Texture button" in the IB and such. All works well except for when a user sets the toolbar to "Text only" mode. When he then clicks the button the toolbar will enable "Icon and Label" on it's own. I have remove alles code and delegates from the toolbar to make sure it is not a code issue.
Then, just to make sure, I created a new project (no code at all) and I can reproduce the issue with a clean NSWindow with a NSToolbar with one NSToolbarItem with a NSButton in it.
Adding the NSButtons via code like:
- (NSArray*)toolbarAllowedItemIdentifiers:(NSToolbar*)toolbar {
return [NSArray arrayWithObject:#"myToolbarMenu"];
}
- (NSArray*)toolbarDefaultItemIdentifiers:(NSToolbar*)toolbar {
return [self toolbarAllowedItemIdentifiers:toolbar];
}
- (NSToolbarItem*)toolbar:(NSToolbar*)toolbar
itemForItemIdentifier:(NSString*)str
willBeInsertedIntoToolbar:(BOOL)flag
{
if ([str isEqualToString:#"myToolbarItem"] == YES) {
NSToolbarItem* item = [[NSToolbarItem alloc] initWithItemIdentifier:str];
[item setView:[[NSButton alloc] init]];
[item setMinSize:NSMakeSize(50,50)];
[item setMaxSize:NSMakeSize(50,50)];
[item setLabel:#"Text"];
return [item autorelease];
}
return nil;
}
But this also has the same effect: when I press a NSToolbarItem with a NSButton in it in "Text only mode" the toolbar itself forces it's mode to "Icon and Text".
Do you have any idea how I can make it work correctly or perhaps have an alternative to creating the nice looking toolbaritems like Safari etc have?
You need to add a menu representation to each NSToolbarItem that has a custom view. Below the line where you allocate the NSToolbarItem add this:
NSMenuItem *menuRep = [[NSMenuItem alloc] initWithTitle:#"Text" action:#selector(targetMethod:) keyEquivalent:#""];
[menuRep setTarget:<target>];
[item setMenuFormRepresentation:menuRep];
As long as the target is valid your items should stay as text-only buttons; otherwise they will be disabled. See Setting a Toolbar Item's Representation.
Normally you would also need to implement validateToolbarItem: in your target, but for custom view items you instead need to override validate: to do something appropriate. See Validating Toolbar Items.
