UIButton.titlelabel setfont不起作用

Question

I have added button in interface builder and referenced them, then I want to change their title font, but it doest work. When I use:

[_button setFont:[UIFont fontWithName:APP_FONT_FUTURASTD_LIGHT size:24.0f]];

it WORKS, but this code is depreciated. So I have looked online to see what to use instead of this code, I found this code to use:

[_button.titleLabel setFont:[UIFont fontWithName:APP_FONT_FUTURASTD_LIGHT size:24.0f]];
_button.titleLabel.font = [UIFont fontWithName:APP_FONT_FUTURASTD_LIGHT size:24.0f];

but NEITHER of this work. I have no idea what to do with it or what is wrong. I have tried to set globally appearance of UIButton, that works too, but I cant use it as I need that font only on some buttons.

Button is as:

@property (nonatomic, weak) IBOutlet UIButton *button;

and added in storyboard.

Font is defined:

#define APP_FONT_FUTURASTD_LIGHT @"FuturaStd-Light"

and added to Info.plist section "Fonts provided by application".

Answer 1

I have found out what the problem was. The other programmer who has started this project has set

[[UIButton appearance] setFont:[UIFont fontWithName:APP_FONT_FUTURASTD_BOLD size:12.0f]];

in CSAppDelegate.m and so all my customizations were overwritten by this.

So to anyone who configures buttons font globally like this, you will not be able to then customize font of some buttons differently. And second advice, if you continue work after someone else make sure that they give you some technical documentation or to explain to you what how and where they did.

EDIT

You can however set appearance for one view in viewWillAppear and then set it back to what you have in your CSAppDelegate.m in viewDidAppear of the view.

EDIT

Now this code is depreciated so you have to use this instead:

[[[UIButton appearance] titleLabel] setFont:UIFont];

Answer 2

The Problem seems to me is the Font name. The Font Name you are using in the code is not the exact name.

You Can Use the Following code to get List Of all Fonts name supported by your app

  // List all fonts on iPhone

for (NSString* family in [UIFont familyNames])
{
    NSLog(@"%@", family);

    for (NSString* name in [UIFont fontNamesForFamilyName: family])
    {
        NSLog(@"  %@", name);
    }
}

from the Console of xcode you can find out the exact name of the font that you added in your application
