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:)];

ΩI've been trying to do this for like an hour now, nothing seems to work:
Things I've tried:
1) Doesn't work.
UIImage *image = [UIImage imageNamed:#"scr1_button_topbar.png"];
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setBackgroundImage: [image stretchableImageWithLeftCapWidth:7.0 topCapHeight:0.0] forState:UIControlStateNormal];
button.frame= CGRectMake(0.0, 0.0, image.size.width, image.size.height);
[button addTarget:self action:nil forControlEvents:UIControlEventTouchUpInside];
UIView *v=[[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, image.size.width, image.size.height) ];
[v addSubview:button];
UIBarButtonItem *forward = [[UIBarButtonItem alloc] initWithCustomView:v];
self.navigationItem.backBarButtonItem= forward;
2) Works, but looks REALLY stupid, it leaves the "Back" text there.
[[UIBarButtonItem appearance] setBackButtonBackgroundImage:[UIImage imageNamed:#"scr2_btnback"] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
3) Button doesn't show
[[UIBarButtonItem appearance] setBackButtonBackgroundImage:[UIImage imageNamed:#"scr2_btnback"] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
And setting the text to #""
4) Setting the left bar button item - Works, but that's a little cheating, I want the back button, not the left button.
UIImage *backImage = [UIImage imageNamed:#"scr2_btnback.png"];
UIButton *backButton = [UIButton buttonWithType:UIButtonTypeCustom];
backButton.frame = CGRectMake(0, 0, backImage.size.width, backImage.size.height);
[backButton setImage:backImage forState:UIControlStateNormal];
[backButton addTarget:self action:#selector(backButton:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *backBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:backButton] ;
self.navigationItem.hidesBackButton = YES;
self.navigationItem.leftBarButtonItem = backBarButtonItem;
Just got told, you can't edit the view of the backBarButtonItem... YEEY me.
I have app i want the button on navigation bar should be on desired position but it is not getting done i have found methods for rightBarButton and leftBarButton but i want this in the center of the navigation bar
UIButton *settingsView = [[UIButton alloc] initWithFrame:CGRectMake(0,0,40,40)];
[settingsView addTarget:self action:#selector(SettingsClicked) forControlEvents:UIControlEventTouchUpInside];
[settingsView setBackgroundImage:[UIImage imageNamed:#"login btn.png"] forState:UIControlStateNormal];
UIBarButtonItem *settingsButton = [[UIBarButtonItem alloc] initWithCustomView:settingsView];
[self.navigationItem setRightBarButtonItem:settingsButton];
NSMutableArray *arrayOfItems = [[NSMutableArray alloc] init];
UIBarButtonItem *flexibleSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil]
[arrayOfItems addObject:flexibleSpace];
[arrayOfItems addObject:theItemYouWantCentered];
[arrayOfItems addObject:flexibleSpace];
self.navigationItem.leftBarButtonItems = arrayOfItems;
I have a UIView that I've made into a button that's added below my Table View:
myUIView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 120,50)];
UIButton *myButton = [UIButton buttonWithType:UIButtonTypeCustom];
[myButton setAutoResizingMask: [UIViewAutoResizingFlexibleWidth|UIViewAutoResizingFlexibleHeight];
[myButton setFrame:CGRectMake(20,0,80,40)];
myButton.titleLabel.textColor = [UIColor blackColor]; //Doesn't seem to work
[myButton setTitle:#"Test" forState:UIControlStateNormal];
myButton.titleLabel.font = [UIFont boldSystemFontOfSize:18];
[myButton setBackgroundImage:[[UIImage imageNamed:#"myImage.png"] stretchableImageWithLeftCapWidth:10.0 topCapHeight:0.0] forState:UIControlStateNormal];
[myButton addTarget:self action:#selector(myAction:) forControlEvents:UIControlEventTouchUpInside];
[myUIView addSubView:myButton];
No matter what I try, the font always seems to be white. What can I do to change the font's color?
You want to use setTitleColor: forState:
[myButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
"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 have an uibarbuttonitem, but i was initialize it using initwithcustomview. I want to change it backgrounds using an image, but i dont know how to do. I was using setBackground method, like this
NSArray *segmentText = [segmentTextMutable copy];
UIImage *image = [[[UIImage alloc] init] autorelease];
image = [UIImage imageNamed:#"bunga.jpg"];
_docSegmentedControl = [[UISegmentedControl alloc] initWithItems:segmentText];
_docSegmentedControl.autoresizingMask = UIViewAutoresizingFlexibleHeight;
_docSegmentedControl.segmentedControlStyle = UISegmentedControlStyleBezeled;
[_docSegmentedControl addTarget:self action:#selector(docSegmentAction:) forControlEvents:UIControlEventValueChanged];
[_docSegmentedControl setBackgroundColor:[UIColor colorWithPatternImage:image]];
but the uibarbuttonitem still not show the image, it's just change the segmented control background, not the barbutton.
Can somebody help me?
Perhaps you want to change the tint-color (#property(nonatomic, retain) UIColor *tintColor) because UISegmentedControl has no background-color (just because it inherits it from UIView does not mean it uses it though)
