Is there any way to use UIAppearance to change the height of a label inside of a UINavigationBar. Here's the code and an image of what's going on so you can understand what the problem is.
[[UINavigationBar appearance] setTitleVerticalPositionAdjustment:-5.0 forBarMetrics:UIBarMetricsDefault];
[[UINavigationBar appearance] setTitleVerticalPositionAdjustment:-5.0 forBarMetrics:UIBarMetricsLandscapePhone];
NSDictionary *textAttributes = [NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:[UIFont fontWithName:#"MarketingScript" size:34.0], nil]
forKeys:[NSArray arrayWithObjects:UITextAttributeFont, nil]];
I ended up solving this by creating a custom UIView:
+(NavigationBarTitleLabel *)titleLabelWithTitle:(NSString *)title {
// this will appear as the title in the navigation bar
NavigationBarTitleLabel *labelWrapper = [[NavigationBarTitleLabel alloc] initWithFrame:CGRectMake(0, 0, 200, 34)];
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 8, 200, 32)];
label.font = [UIFont fontWithName:#"MarketingScript" size:28.0];
label.text = title;
label.textColor = XHEXCOLOR(0XFFFFFF);
label.textAlignment = UITextAlignmentCenter;
label.backgroundColor = [UIColor clearColor];
label.layer.shadowColor = [UIColor blackColor].CGColor;
label.layer.shadowRadius = 2;
[labelWrapper addSubview:label];
[labelWrapper sizeToFit];
return labelWrapper;
}
and then setting the titleView property on the navigationItem:
self.navigationItem.titleView = [NavigationBarTitleLabel titleLabelWithTitle:self.title];
Probably you can get the UIAppearance for UILabel inside UINavigationBar.

I am developing one application for iphone and in that i have some issues regarding adding more then one UILabel in navigation bar at a specific position.
What i want is in following images
in above image there is one backbar button and one imageview as shown with arrow-mark. Other then that all white box is for difrent UILabels to show in navigation bar.
There is only one UIImageView in the navigation bar and one left bar button. Now problem is that i don't know how to add multiple UILabel in navigation bar at a specific position.
Till now what i have worked is to add only button and UIImageView with the right bar button array or left bar button array, but that only add items in sequnce.
So can anyone please guide me that how can anyone add UILabels or any other item at a specific position..
you can add Multiple UIlabel or Image as look like bellow image:-
this can do using bellow code you can change Label and imageView frame and put as your requirement
- (void)viewDidLoad
{
UIView *btn = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 60)];
UILabel *label;
label = [[UILabel alloc] initWithFrame:CGRectMake(5, 25, 200, 16)];
label.tag = 1;
label.backgroundColor = [UIColor clearColor];
label.font = [UIFont boldSystemFontOfSize:16];
label.adjustsFontSizeToFitWidth = NO;
label.textAlignment = UITextAlignmentLeft;
label.textColor = [UIColor whiteColor];
label.text = #"My first lable";
label.highlightedTextColor = [UIColor whiteColor];
[btn addSubview:label];
[label release];
label = [[UILabel alloc] initWithFrame:CGRectMake(0, 30, 200, 16)];
label.tag = 2;
label.backgroundColor = [UIColor clearColor];
label.font = [UIFont boldSystemFontOfSize:16];
label.adjustsFontSizeToFitWidth = NO;
label.textAlignment = UITextAlignmentRight;
label.textColor = [UIColor whiteColor];
label.text = #"second line";
label.highlightedTextColor = [UIColor whiteColor];
[btn addSubview:label];
[label release];
UIImageView *imgviw=[[UIImageView alloc]initWithFrame:CGRectMake(170, 10, 20, 20)];
imgviw.backgroundColor = [UIColor blackColor];
imgviw.image=[UIImage imageNamed:#"a59117c2eb511d911cbf62cf97a34d56.png"];
[btn addSubview:imgviw];
self.navigationItem.titleView = btn;
}
You can add subviews directly to the navigationBar -
UINavigationBar *navBar = navController.navigationBar;
[navBar addSubview: yourLabel];
yourLabel frame origin will be relative to the navigation bar
Try this code
UIView *buttonContainer = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 200, 44)];
buttonContainer.backgroundColor = [UIColor clearColor];
UIButton *button0 = [UIButton buttonWithType:UIButtonTypeCustom];
[button0 setFrame: CGRectMake(160, 7 , 40, 30)];
[button0 setTitle:#"Sort" forState:UIControlStateNormal];
button0.titleLabel.font = [UIFont fontWithName:#"Helvetica" size:12];
[button0 setBackgroundImage:[UIImage imageNamed:#"Btn_Sort_Btn_Sort_Places.png"] forState:UIControlStateNormal];
[button0 addTarget:self action:#selector(sortAction) forControlEvents:UIControlEventTouchUpInside];
[button0 setShowsTouchWhenHighlighted:YES];
[buttonContainer addSubview:button0];
self.navigationItem.titleView = buttonContainer;
UILabel *lbl_title = [[UILabel alloc] initWithFrame:CGRectMake(10, 0 , 140, 40)];
lbl_title.text = str_HeaderTitle;
lbl_title.textColor = [UIColor whiteColor];
lbl_title.font = [UIFont fontWithName:#"Helvetica-Bold" size:16];
lbl_title.backgroundColor = [UIColor clearColor];
lbl_title.textAlignment = NSTextAlignmentCenter;
[buttonContainer addSubview:lbl_title];
You can set an arbitrary view instead of a view controller's title:
myViewController.navigationItem.titleView = someView;
Note that most likely the view's frame will be restricted to make room for leftBarButtonItem and rightBarButtonItem.
UILabel *label=[[UILabel alloc] initWithFrame:CGRectMake(50, 2, 20, 15)];
[label setBackgroundColor:[UIColor greenColor]];
UIImageView *imgView=[[UIImageView alloc] initWithFrame:CGRectMake(40, 20, 150, 10)];
[imgView setBackgroundColor:[UIColor redColor]];
[[self.navigationController navigationBar] addSubview:label];
[self.navigationController.navigationBar addSubview:imgView];
Have a look at this piece of code. With some modifications it should solve your problem:
UIButton *imageButton = [UIButton buttonWithType:UIButtonTypeCustom];
[imageButton setFrame:CGRectMake(15, 0, 57, 44)];
[imageButton setBackgroundImage:[UIImage imageNamed:#"someImage.png"] forState:UIControlStateNormal];
UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(140, 0, 250, 44)];
[titleLabel setText:#"some title"];
[titleLabel setBackgroundColor:[UIColor clearColor]];
[titleLabel setTextColor:[UIColor whiteColor]];
[titleLabel setFont:[UIFont boldSystemFontOfSize:20]];
[self.navigationController.navigationBar addSubview:imageButton];
[self.navigationController.navigationBar addSubview:titleLabel];
Just modify the values in the CGRectMake() to fit your needs.
I have made an iPad application, in that I used navigation control,
now in the title bar , I want to put image on left side, so I hide title bar with label, but label is not covering entire width of title bar,
IL APP IN THE SCREEN SHOT,
here is the code snippet,
UILabel *titleView = (UILabel *)self.navigationItem.titleView;
if (!titleView) {
titleView = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 800, 50)];
titleView.backgroundColor = [UIColor clearColor];
titleView.font = [UIFont boldSystemFontOfSize:20.0];
titleView.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.5];
titleView.textColor = [UIColor yellowColor]; // Change to desired color
titleView.backgroundColor=[UIColor blackColor];
titleView.text = #"IL APP";
titleView.textAlignment=UITextAlignmentCenter;
//self.navigationItem.titleView = titleView;
[self.navigationItem setTitleView:titleView];
[titleView release];
}
#Gama as far as your question is concerned you are asking to put an Image but your real issue being described is that the label is not covering up the title bar. To cover that properly you can use
UILabel *titleView = (UILabel *)self.navigationItem.titleView;
if (!titleView) {
titleView = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 100, 32)];
titleView.backgroundColor = [UIColor clearColor];
titleView.font = [UIFont boldSystemFontOfSize:20.0];
titleView.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.5];
titleView.textColor = [UIColor yellowColor]; // Change to desired color
//titleView.backgroundColor=[UIColor blackColor];
titleView.text = #"IL APP";
titleView.textAlignment=UITextAlignmentCenter;
[self.navigationItem setTitleView:titleView];
[titleView release];
}
[self.navigationController.navigationBar setTintColor:[UIColor blackColor]];
For using an image you can use an image view instead of a label to be assigned as the titleView for navigationItem.
Hope it helps
I tried to solved your problem but I get the same result.
But you can hide navigation bar and add the UILabel in to your ViewController
self.navigationController.navigationBarHidden = FALSE;
[self.view addSubview:titleview];
UIImageView *imageNav = [[UIImageView alloc] initWithImage: [UIImage imageNamed: #"navImage.png"]];
[self.navigationController.navigationBar addSubview:imagenav];
[self.navigationController.navigationBar sendSubviewToBack:imageNav];
[imageNav release];
Hi i wanted to do the same thing and i saw your posting, i basically used some of the code you provided and modified it a little and got it to work see below:
//declare and initialize your imageView
UIImageView *titleImage = (UIImageView *)self.navigationItem.titleView;
titleImage = [[UIImageView alloc]
initWithFrame:CGRectMake((self.navigationController.navigationBar.frame.size.width/2)
- (100/2), 0, 100, self.navigationController.navigationBar.frame.size.height)];
//setting the image for UIImageView
titleImage.image = [UIImage imageName:#"photo.jpg"];
//NOTE: you have to do this line at the bottom to add image to the navigation bar Try it it WORKS!
self.navigationItem.titleView = titleImage;
I want to use UILabel in ContainerView.
So I am using this code for that.
UILabel *myLabel = [[[UILabel alloc] initWithFrame:CGRectMake(16, 60, 300, 150)] autorelease];
myLabel.numberOfLines = 0;
myLabel.font = [UIFont systemFontOfSize:13.5];
myLabel.text = [theQuiz objectAtIndex:row+3] ;
myLabel.lineBreakMode = UILineBreakModeWordWrap;
myLabel.backgroundColor = [UIColor clearColor];
myLabel.layer.cornerRadius = 8.0;
[myLabel sizeToFit];
[self.view addSubview:myLabel];
//ContainerView
UIView *ChallengeView = [[UIView alloc] initWithFrame:CGRectMake(8, 55, 300, 10 + Challenge.frame.size.height)];
ChallengeView.layer.borderColor = [[UIColor purpleColor ] CGColor];
[ChallengeView setBackgroundColor:[UIColor whiteColor]];
ChallengeView.layer.cornerRadius = 8 ;
ChallengeView.layer.borderWidth = 1.5;
[self.view addSubview:ChallengeView];
[ChallengeView release];
Now problem is that when i set background color for ContainerView it hides the text of myLabel
Any Solution ??
What is happening is that you containerView is being added above label either you add label after containerView or do this:
[self.view bringSubviewToFront:myLabel];
You add the ChallengeView first , Then add the myLabel.
Otherwise u can do as like #xs2bush said,
[self.view bringSubviewToFront:myLabel];
Bcz the ChallengeView hides the label.
I'm using UINavigationItem's titleView property to set a custom UILabel with my desired font size/color. Here's my code:
self.headerLabel = [[UILabel alloc] initWithFrame:CGRectMake(0.0, 0.0, 400.0, 44.0)];
self.headerLabel.textAlignment = UITextAlignmentCenter;
self.headerLabel.backgroundColor = [UIColor clearColor];
self.headerLabel.font = [UIFont boldSystemFontOfSize:20.0];
self.headerLabel.textColor = [UIColor colorWithRed:0.259 green:0.280 blue:0.312 alpha:1.0];
self.navigationItem.titleView = self.headerLabel;
In the navigation bar I also have a left bar button. The result is: the text isn't properly centered. I've tried setting the x origin of the label, but this has no effect.
In stead of initWithFrame just use init and put [self.headerLabel sizeToFit] after your last line of code.
If you make the headerLabel a subview of the titleView, you can then set headerLabel's frame to control where it goes within the titleView.
The way you are doing it now, you don't have that control. I think the OS chooses the titleView's frame for you based on the space available.
Hope this helps!
I've used custom title labels for my nav bars in every app I have in the app store. I've tested many different ways of doing so and by far the easiest way to use a custom label in a navigation bar is to completely ignore titleView and insert your label directly into navigationController.view.
With this approach, it's easy to have the title label's frame always match the navigationBar's frame -- even if you are using a custom navBar with a non-standard size.
- (void)viewDidLoad {
[self.navigationController.view addSubview:self.titleLabel];
[super viewDidLoad];
}
- (BOOL)shouldAutorotateToInterfaceOrientation:
(UIInterfaceOrientation)interfaceOrientation {
return YES;
}
- (void)didRotateFromInterfaceOrientation:
(UIInterfaceOrientation)fromInterfaceOrientation {
[self frameTitleLabel];
}
- (UILabel *) titleLabel {
if (!titleLabel) {
titleLabel = [[UILabel alloc]
initWithFrame:self.navigationController.navigationBar.frame];
titleLabel.font = [UIFont fontWithName:#"Helvetica-Bold" size:18];
titleLabel.text = NSLocalizedString(#"Custom Title", nil);
titleLabel.textAlignment = UITextAlignmentCenter;
titleLabel.lineBreakMode = UILineBreakModeTailTruncation;
}
return titleLabel;
}
- (void) frameTitleLabel {
self.titleLabel.frame = self.navigationController.navigationBar.frame;
}
The one caveat to this approach is that your title can flow over the top of any buttons you have in the navBar if you aren't careful and set the title to be too long. But, IMO, that is a lot less problematical to deal with than 1) The title not centering correctly when you have a rightBarButton or 2) The title not appearing if you have a leftBarButton.
I have a same problem; I just somehow solved this issue by calculating the title length and set the label frame width accordingly. Although this is not a perfect one but can be manageable. Here is the code.
label = [[UILabel alloc] init];
label.backgroundColor = [UIColor clearColor];
label.font = [ UIFont fontWithName: #"XXII DIRTY-ARMY" size: 32.0 ];
label.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.0f];
label.textAlignment = UITextAlignmentCenter;
label.textColor =[UIColor orangeColor];
//label.text=categoryTitle;
CGFloat verticalOffset = 2;
NSString *reqSysVer = #"5.0";
NSString *currSysVer = [[UIDevice currentDevice] systemVersion];
if ([currSysVer compare:reqSysVer options:NSNumericSearch] != NSOrderedAscending)
{
if (categoryTitle.length > 8)
{
label.frame = CGRectMake(0, 0, 300, 44);
}else {
label.frame = CGRectMake(0, 0, 80, 44);
}
self.navigationItem.titleView = label;
self.navigationItem.title=label.text;
[[UINavigationBar appearance] setTitleVerticalPositionAdjustment:verticalOffset forBarMetrics:UIBarMetricsDefault];
[[UIBarButtonItem appearance] setTintColor:[UIColor newBrownLight]];
}
Just calculate exact frame size needed and align to left:
UIFont* font = [UIFont fontWithName:#"Bitsumishi" size:20];
CGSize maximumLabelSize = CGSizeMake(296,9999);
CGSize expectedLabelSize = [title sizeWithFont:font constrainedToSize:maximumLabelSize lineBreakMode:UILineBreakModeCharacterWrap];
CGRect frame = CGRectMake(0, 0, expectedLabelSize.width, expectedLabelSize.height);
UILabel *label = [[[UILabel alloc] initWithFrame:frame] autorelease];
label.font = font;
label.textAlignment = UITextAlignmentLeft;
label.text = title;
self.titleView = label;
UIView *vw = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 40)];
UILabel *lbl = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 320, 40)];
lbl.text = #"Home";
lbl.textAlignment = UITextAlignmentCenter;
lbl.backgroundColor = [UIColor clearColor];
lbl.textColor = [UIColor whiteColor];
lbl.font = [UIFont fontWithName:#"HelveticaNeue-Bold" size:20];
lbl.shadowColor = [UIColor blackColor];
lbl.shadowOffset = CGSizeMake(0,1);
self.navigationItem.titleView = vw;
[self.navigationItem.titleView addSubview:lbl];
What worked for me was to update the titleView frame in the viewDidAppear method.
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
UIView *titleView = self.navigationItem.titleView;
CGRect navBarFrame = self.navigationController.navigationBar.frame;
[titleView setFrame:CGRectMake((CGRectGetWidth(navBarFrame) - TitleWidth) / 2, (CGRectGetHeight(navBarFrame) - TitleHeight) / 2, TitleWidth, TitleHeight)];
}
i want change title's color of navigation controller but i dont know why doesn't work !
UILabel *label = [[[UILabel alloc] init] autorelease];
label.textColor = [UIColor yellowColor];
self.navigationItem.titleView = label;
i figured out my problem :
CGRect frame = CGRectMake(0, 0, 310, 44);
UILabel *label = [[[UILabel alloc] initWithFrame:frame] autorelease];
label.backgroundColor = [UIColor clearColor];
label.font = [UIFont systemFontOfSize:25];
label.textAlignment = UITextAlignmentCenter;
label.textColor = [UIColor brownColor];
self.navigationItem.titleView = label;
label.text = NSLocalizedString(#"YOUR TEXT", #"");
now how can add a logo on my navigation bar ? :D
When you assign the UILabel your not giving it a size so its ending up with a frame of 0x0 - by adding [label sizeToFit]; after you've added the text you'll get what you want.
Or you can set the size of the label when you create it with initWithFrame:(CGRect)frame
Do you want to change the color of the whole navigation bar or just the UILabel in the middle of it? Assuming you want to recolor the whole bar, you can do it in Interface Builder by setting the tint color, or you can use navigationController.navigationBar.tintColor = UIColor(...)
