So I have a UIToolbar with 4 UIBarButtonItems on it (2 of them being Flexible Space) the middle one is of Style: Plain with a Title set "Settings" and then the far right button is a 'Done' button to close the view.
Everything looks good and works the way I want except for the middle text button is "clickable", it does nothing when you click on it but there is a white glow that appears around the text once it's touched.
The only options you get with a UIBarButtonItem is 'Enabled' which if turned OFF makes the text greyed out.
I was able to almost simulate the way it looks by creating a UILabel and adding as a subview to the UIToolbar but I was wondering if there's a simpler way to doing this.
Thanks
use the customView of UIBarButtonItem, to set an UILAbel as customView. the item will not be clickable.
UILabel *yourLabel = ...;
UIBarButtonItem *theBarItem = [[UIBarButtonItem alloc] initWithCustomView:yourLabel];
that's all.

I have a UIBarButtonItem in a Navigation Bar with the text title "Save". When I transition to a fullscreen UIPopoverController and then dismiss it, the text in my UIBarButtonItem gets truncated to "S..e". For all other segues and views I have no problem when returning.
I've tried manually changing the width and setting "possibleTitles" to include long words but I can't stop the truncation.
I'm using a custom font if that makes a difference.
Try to init your UIBarButtonItem with a custom view.
[[UIBarButtonItem alloc] initWithCustomView:yourView];
Just make sure your custom view has the right frame (e.g. for an UILabel ,wide enough to not truncate its content). Things should work fine.
Perhaps helpful, but a UIBarButtonItem with a custom view (ex: UILabel) that is inserted into a UIToolbar can take on the intrinsic size of its contents as long as translatesAutoresizingMaskIntoConstraints is set to false. I believe this may work for UINavigationBar too:
private let barButtonLabel: UIBarButtonItem = {
let label = UILabel(frame: .zero)
label.translatesAutoresizingMaskIntoConstraints = false
return UIBarButtonItem(customView: label)
}()
I have UIBarButtonItem which is taken using interface builder.
Its outlet is taken as follow :
{
IBOutlet UIBarButtonItem *itemNext, *itemPrevious, *itemSubmit;
}
so in my storyboard it looks like as following image.
Now, my question is how can i add UILabel just before rightBarButtonItem item ?
Note : UIBarButtonItem is not on the navigationController its set on the bottom of the screen as shown in the image.
i am unable to drag and drop the UILabel on UIBarButtonItem anyone can suggest me how can i do that?
UILabel can only be added as a subview to UIToolbar or UINavigationBar.
You can add a UIBarItem. Use setTitleTextAttributes:forState: on UIBarItem to get attributed string properties similar to UILabel.
I want to developer app with a custom navigation bar like in the following images:
I think that i need to subclass UINavigationBar and add button to centre of nav bar, but i don't really know how to make navigation bar look like on image. Can you please give me advice what should i do, links to any kind of documentation would be awesome!

EDIT:
My idea is next: make custom navigation bar height little bigger than default size, and add background image with arrow in it and with some transparency on the edges.
If you want a button (you probably do want) you can achieve it completely by subclassing UINavigationBar. You should remember that height of UINavigationBar is read-only property.
Style but not tappable:
So let's assume we subclass the navigation bar and add button there. You could do this and it will be going look great. For example:
- (void)drawRect:(CGRect)rect
{
self.backgroundColor = [UIColor lightGrayColor];
UIButton *myButton = [[UIButton alloc] initWithFrame:CGRectMake(self.frame.size.width/2-50, 0 , 100, 100)];
[myButton setBackgroundColor:[UIColor lightGrayColor]];
[myButton setTitle:#"Normal" forState:UIControlStateNormal];
[myButton setTitle:#"Highlighted" forState:UIControlStateHighlighted];
[self addSubview:myButton];
[self sendSubviewToBack:myButton];
}
But you will facing a problem that your button is non tapeable below UINvaigationBar. (I post an image on the bottom of the answer)
So there is clearly not a path you want to follow. Don't even try that.
Style but not tappable 2:
You may override this method in your navigation bar subclass
- (CGSize) sizeThatFits:(CGSize)size {
return CGSizeMake(custom_width, custom_height);
}
And then mask it using UIBezierPath for example
The right (tappable) way:
You have to create a view stick to your UINavigationBar. What i will do here (if you want it to every screen) is:
Make a Category of UIViewController which can draw (for example - this is easiest way) UIButton.
Style this 'UIButton' whatever you want (if you want
Pin action to 'UIButton': [btn addTarget:self action:#selector(menuShow:) forControlEvents:UIControlEventTouchUpInside];
menuShow: method should be declare in your category
You can call drawing button every time you want to redraw view controller.
As you can see there there will be two separates View: UINavigationBar and UIButton. This is allow you to set content under this little button and make it tapable.
So why just don't hide navigation bar, and use different view? Because iOS7 ;) When Apple change it in iOS7 for example then you have to rebuild your pseudo NavigationBar, with only additional view, you don't need to do anything.
You do not need to subclass UINavigationBar. Create UIView add to it UIImageView as background with image in the shape you need, add button.
Subclass UINavigationController hide UINavigationBar, add custom navigation bar.
First Hide navigation bar using -
self.navigationController.navigationBarHidden = YES;
Then create UIView with required height,height of navigationBar is 44px.Then create background image view, object of required UIButton and add all objects on created UIView as a subview.It will look like navigationBar.Thank you.
You can add your custom shaped view as titleView on the navigation bar.
Just make sure that clipsToBounds is set to NO, so it doesn't get clipped.
I would like to setup the navigation controller bar button item to be an image.
I have read the following - Add image to a navigationItem's title
I understand how to setup this as an image. I am actually looking to set this up as the setting cog, within the bar button item (like a cog icon). I have seen this before in other apps, I would like to know if there is a default style to initialise for this or normally if this is achieved by the image route as above.
If this is above, does anyone know where this (kind of) default image styled icon is available, or would I need to make one?
Have you tried using the initWithCustomView option of UIBarButtonItem? A sample code will look like the below line.
UIBarButtonItem *aButton = [[UIBarButtonItem alloc] initWithCustomView:[[UIImageView alloc] initWithImage:[UIImage imageNamed:#"settings.png"]]];
Another way to do this is,
UIBarButtonItem *aButton = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"settings.png"] style:UIBarButtonItemStyleBordered target:self action:#selector(buttonTapped)];
If you use storyboard, you can directly:
Drag a Button in the navigation bar instead of a Bar Button Item. It will automatically create a Button Bar Item for you with a Button inside it.
Enter a title for the Button Bar Item
Set an image for the Button with a Custom type.
It should works.
I'm trying to use a UIBarButtonItem to put a title on my UIToolbar. I'm using the plain style and that looks fine, but I can't seem to get it to stop highlighting on touch. The Shows Touch When Highlighted option isn't available for the bar button items. Is there a quick and easy way to do this? I'm trying to do the building in interface builder so I can see what I'm doing. I'd prefer not to build the toolbar in the view did load every time.
The property responsible for this is accessible in the UIButton class:
myButton.showsTouchWhenHighlighted = NO;
You can access this (programmatically) in a UIBarButtonItem by assigning a UIButton to the bar button item's customView property, and configuring the button. You can do this in Interface Builder too: drag a UIButton onto a UIToolbar, and it will automatically embed it in a UIBarButtonItem for you - then look for the "Shows Touch On Highlight" checkbox under the button's settings.
Incidentally, I don't know how you're customising your buttons so feel free to ignore this, but if your button looks and behaves like a standard toolbar item then users will expect the glow effect.
I wanted a solution that could be used without any modification to my XIB structure.
The most obvious and simple one worked: subclass UIBarButtonItem:
UITitleBarButtonItem.h:
//
// UITitleBarButtonItem.m
// Created by Guillaume Cerquant - MacMation on 09/08/12.
//
/*
* A UIBarButtonItem that does not show any highlight on the touch
* Drag and drop a normal UIBarButtonItem in your xib and set its subclass to UITitleBarButtonItem
*/
#interface UITitleBarButtonItem : UIBarButtonItem
#end
UITitleBarButtonItem.m:
#import "UITitleBarButtonItem.h"
#implementation UITitleBarButtonItem
// Only caring about UITitleBarButtonItem set up in Interface Builder. Update this class if you need to instantiate it from code
- (void) awakeFromNib {
UIView *theView = [self valueForKey:#"view"];
if ([theView respondsToSelector:#selector(setUserInteractionEnabled:)]) {
theView.userInteractionEnabled = NO;
}
}
#end
Tested on iOS 5 and the one we aren't allowed to talk yet.
Alternative: Use a UIBarButtonItem in the plain style and additionally cover the toolbar in the appropriate area with a UIView that has a clear background. The view consumes the taps and hides them from the bar button item. Make sure you set the autoresizing mask correctly.
My solution was to set it to disabled, and adjust the titleAttributes for each UIControlState
let attributes: [NSAttributedStringKey: Any] = [
.font: UIFont.boldSystemFont(ofSize: 16),
.foregroundColor: UIColor.white
]
barButton.setTitleTextAttributes(attributes, for: .enabled)
barButton.setTitleTextAttributes(attributes, for: .disabled)
barButton.isEnabled = false
