Change the font of a UIBarButtonItem

Question

I have a UIBarButtonItem in my UIToolbar titled

Answer 1

These are great answers above. Just updating for iOS7:

NSDictionary *barButtonAppearanceDict = @{NSFontAttributeName : [UIFont fontWithName:@"HelveticaNeue-Thin" size:18.0] , NSForegroundColorAttributeName: [UIColor whiteColor]};
    [[UIBarButtonItem appearance] setTitleTextAttributes:barButtonAppearanceDict forState:UIControlStateNormal];

Answer 2

swift 3

barButtonName.setTitleTextAttributes( [NSFontAttributeName : UIFont.systemFont(ofSize: 18.0),NSForegroundColorAttributeName : UIColor.white], for: .normal) 

Answer 3

To be precise, this can be done as below

[buttonItem setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys: 
    [UIFont fontWithName:@"Helvetica-Bold" size:26.0], NSFontAttributeName,
    [UIColor greenColor], NSForegroundColorAttributeName,
    nil] 
                          forState:UIControlStateNormal];

Or with object literal syntax:

[buttonItem setTitleTextAttributes:@{
     NSFontAttributeName: [UIFont fontWithName:@"Helvetica-Bold" size:26.0],
     NSForegroundColorAttributeName: [UIColor greenColor]
} forState:UIControlStateNormal];

For convenience, here's the Swift implementation:

buttonItem.setTitleTextAttributes([
        NSAttributedStringKey.font: UIFont(name: "Helvetica-Bold", size: 26.0)!,
        NSAttributedStringKey.foregroundColor: UIColor.green],
    for: .normal)

Answer 4

You can create a custom UIView programmatically:

UIView *buttonItemView = [[UIView alloc] initWithFrame:buttonFrame];

Then add images, labels or whatever you like to your custom view:

[buttonItemView addSubview:customImage];

[buttonItemView addSubview:customLabel];

...

Now put it in your UIBarButtomItem.

UIBarButtonItem *barButtonItem = [[UIBarButtonItem alloc] initWithCustomView:buttonItemView];

And finally add barButtonItem to you navigation bar.

Answer 5

Swift 5 Implementation

rightButtonItem.setTitleTextAttributes([
            NSAttributedString.Key.font: UIFont(name: "Helvetica-Bold", size: 26.0)!,
            NSAttributedString.Key.foregroundColor: UIColor.green],
        for: .normal)

Answer 6

Throughout App:

if let font = UIFont(name: "AvenirNext-DemiBold", size: 15) {
        UIBarButtonItem.appearance().setTitleTextAttributes([NSFontAttributeName: font,NSForegroundColorAttributeName:TOOLBAR_TITLE_COLOR], forState: UIControlState.Normal)

    }
