I tried this code:
custom barbuttonitem:
-(id)initWithImage:(UIImage *)image title:(NSString*)title target:(id)target action:(SEL)action {
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame= CGRectMake(0.0, 0.0, image.size.width, image.size.height);
button.titleLabel.font = [UIFont boldSystemFontOfSize:12];
button.titleLabel.shadowOffset = CGSizeMake(0, -1);
button.titleLabel.shadowColor = [UIColor colorWithWhite:0 alpha:0.5];
button.titleLabel.textColor = [UIColor redColor];
[button setTitle:title forState:UIControlStateNormal];
[button setBackgroundImage:image forState:UIControlStateNormal];
[button addTarget:target action:action forControlEvents:UIControlEventTouchUpInside];
UIView *view =[[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, image.size.width, image.size.height) ];
[view addSubview:button];
self = [[UIBarButtonItem alloc] initWithCustomView:view];
return self;
}
and used it:
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"my_account_icon.png"] title:#"" target:self action:#selector(buttonClick:)];
But in ios 6 event not activate, ios 5 run nomal, please help me !!!!
UIBarButtonItems with a customView set will not fire actions.
Try the following:
-(id)initWithImage:(UIImage *)image title:(NSString*)title target:(id)target action:(SEL)action
{
//create whatever custom views you need
UIView *view =[[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, image.size.width, image.size.height) ];
UITapGestureRecognizer * gestureRec = [[UITapGestureRecognizer alloc] initWithTarget: target action: action];
[view addGestureRecognizer: gestureRec];
//add your custom subviews to the view
self = [[UIBarButtonItem alloc] initWithCustomView:view];
return self;
}
Adding gesture recognizer to the subview of the UIBarButtonItem worked for me, even if UIBarButtonItem is initialized with the custom view.
Good luck!
"Now Playing" is in One line in UIBarButtonItem. I have to put it in two lines, like "Now" is ay top and "Playing" is at bottom.I have written the following line of code:-
UIBarButtonItem *flipButton = [[UIBarButtonItem alloc]
initWithTitle:#"Now Playing"
style:UIBarButtonItemStyleBordered
target:self
action:#selector(flipView)];
self.navigationItem.rightBarButtonItem = flipButton;
So i want to pu line break in between "Now Playing". So please help me out.
Yes you can. It is fairly simple to do. Create a multiline button and use that. The "trick" is to set the titleLabel numberOfLines property so that it likes multilines.
UIButton* button = [UIButton buttonWithType:UIButtonTypeCustom];
button.titleLabel.numberOfLines = 0;
[button setTitle:NSLocalizedString(#"Now\nPlaying", nil) forState:UIControlStateNormal];
[button sizeToFit];
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:button];
When you specify a button type of custom it expects you to configure everything... selected state, etc. which is not shown here to keep the answer focused to the problem at hand.
- (void)createCustomRightBarButton_
{
UILabel * addCustomLabel = [[[UILabel alloc] initWithFrame:CGRectMake(0, 0, 64, 25)] autorelease];
addCustomLabel.text =#"Now\nPlaying";
addCustomLabel.textColor = [UIColor whiteColor];
addCustomLabel.font = [UIFont boldSystemFontOfSize:11];
addCustomLabel.numberOfLines = 2;
addCustomLabel.backgroundColor = [UIColor clearColor];
addCustomLabel.textAlignment = UITextAlignmentCenter;
CGSize size = addCustomLabel.bounds.size;
UIGraphicsBeginImageContext(size);
CGContextRef context = UIGraphicsGetCurrentContext();
[addCustomLabel.layer renderInContext: context];
CGImageRef imageRef = CGBitmapContextCreateImage(context);
UIImage * img = [UIImage imageWithCGImage: imageRef];
CGImageRelease(imageRef);
CGContextRelease(context);
self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithImage:img
style:UIBarButtonItemStyleBordered
target:self
action:#selector(flipView)]
autorelease];
}
You can host a UIButton as customView inside your bar button (either set the bar button item customView or you can drag one directly on top of your UIBarButtonItem), hook it up as an outlet, then do;
-(void) viewDidLoad
{
//...
self.customButton.titleLabel.numberOfLines = 2;
self.customButton.suggestionsButton.titleLabel.lineBreakMode = UILineBreakModeWordWrap;
self.customButton.suggestionsButton.titleLabel.textAlignment = UITextAlignmentCenter;
}
which in my case becomes
I create 2 PNG images by myself, and it looks good.
UIImage *img = [UIImage imageNamed:#"nowplaying.png"];
UIBarButtonItem *nowPlayingButtonItem = [[[UIBarButtonItem alloc] initWithImage:img style:UIBarButtonItemStyleBordered target:delegate action:#selector(presentNowPlayingMovie)] autorelease];
I need to stick a toolBar with a UITextField inside to a keyboard.
What if I make the whole toolBar (which I think is the textField's super view) the inputAccessoryView of its textField?
I mean like this:
textField.inputAccessoryView = toolBar; // textField is inside the toolBar
I've been trying on this but I have not made it work yet.
Anyone can help?
Or is there another way to achieve what I want?
- (void)viewDidLoad
{
[self createAccessoryView];
[textField setDelegate:self];
[textField setKeyboardType:UIKeyboardTypeDefault];
[textField setInputAccessoryView:fieldAccessoryView];
}
- (void)createAccessoryView
{
CGRect frame = CGRectMake(0.0, self.view.bounds.size.height, self.view.bounds.size.width, 44.0);
fieldAccessoryView = [[UIToolbar alloc] initWithFrame:frame];
fieldAccessoryView.barStyle = UIBarStyleBlackOpaque;
fieldAccessoryView.tag = 200;
[fieldAccessoryView setBarStyle:UIBarStyleBlack];
UIBarButtonItem *spaceButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:#selector(done:)];
UISegmentedControl* segmentedControl = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:NSLocalizedString(#"Previous", #""), NSLocalizedString(#"Next", #""), nil]];
[segmentedControl addTarget:self action:#selector(segmentAction:) forControlEvents:UIControlEventValueChanged];
segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
[segmentedControl setMomentary:YES];
UIBarButtonItem *segmentButton = [[UIBarButtonItem alloc] initWithCustomView:segmentedControl];
[fieldAccessoryView setItems:[NSArray arrayWithObjects:segmentButton, spaceButton, doneButton, nil] animated:NO];
[segmentButton release];
[spaceButton release];
[doneButton release];
[segmentedControl release];
}
When are you setting the property? You may be setting it after the view has already loaded.
Try setting it in
- (void) viewDidLoad
I have a toolbar created programaticaly with 3 buttons (only 1 shown here). After a lot of Googling I was able to set a nice background image but now I don't know where to put
the code for the action: target:self action:#selector(pressButton3:) method. So I have a non-working button with nice colorful image. I've tried a lot of examples and if the button is working the image is not working and vice versa. Please help.
//Add buttons
UIImage *buttonImage = [UIImage imageNamed:#"mapp.png"];
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setImage:buttonImage forState:UIControlStateNormal];
button.frame = CGRectMake(0, 0, buttonImage.size.width, buttonImage.size.height);
UIBarButtonItem *systemItem1 = [[UIBarButtonItem alloc] initWithCustomView:button];
[systemItem1 initWithBarButtonSystemItem:UIBarButtonItemStylePlain target:self action:#selector(pressButton1:)];
//add to array
NSArray *items = [NSArray arrayWithObjects: systemItem1, nil];
I think you're button should work if you add:
[button addTarget:self action:#selector(pressButton1:) forControlEvents:UIControlEventTouchUpInside];
And remove the line:
[systemItem1 initWithBarButtonSystemItem:UIBarButtonItemStylePlain target:self action:#selector(pressButton1:)];
I want my leftBarButtonItem to be a red button. I haven't figured out how to do that. I'm using the following code to construct the navigation bar and button.
Any help is appreciated.
lq
UINavigationBar *navBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
navBar.barStyle = UIBarStyleBlack;
navBar.translucent = YES;
[self.view addSubview:navBar];
[navBar release];
UIBarButtonItem *clearButton = [[UIBarButtonItem alloc]
initWithTitle:#"Clear"
style:UIBarButtonItemStyleBordered
target:self
action:#selector(myAction:)];
navItem.leftBarButtonItem = clearButton;
[navBar pushNavigationItem:navItem animated:false];
[navBar setDelegate:self];
[navItem release];
[clearButton release];
Maybe you will find a nicer solution in this posting at Stack Overflow or you can go the way using a UISegmentedControl
UISegmentedControl *button = [[[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:#"Clear", nil]] autorelease];
button.momentary = YES;
button.segmentedControlStyle = UISegmentedControlStyleBar;
button.tintColor = [UIColor redColor];
...
UIBarButtonItem *clearButton = [[UIBarButtonItem alloc] initWithCustomView:button];
navItem.leftBarButtonItem = clearButton;
