UITextAttributeTextShadowOffset được dùng nữa

Question

Tôi cố gắng để addapt mã của tôi lên iOS 7.

[[UIBarButtonItem appearance] setTitleTextAttributes:@{ 
          UITextAttributeTextColor: [UIColor colorWithRed:214.0f/255.0f green:210.0f/255.0f blue:197.0f/255.0f alpha:1.0f], 
         UITextAttributeTextShadowColor: [UIColor colorWithWhite:0.0f alpha:0.750f], 
        UITextAttributeTextShadowOffset: [NSValue valueWithCGSize:CGSizeMake(0.0f, 1.0f)] 

Tôi nhận được một vài lỗi, UITextAttributeColor is deprecated, UITextAttributeTextShadowColor is deprecated, và UITextAttributeTextShadowOffset is deprecated.

Answer 1

NSShadow *shadow = [NSShadow new]; 
[shadow setShadowColor: [UIColor colorWithWhite:0.0f alpha:0.750f]]; 
[shadow setShadowOffset: CGSizeMake(0.0f, 1.0f)]; 

[[UIBarButtonItem appearance] setTitleTextAttributes:@{ 
    NSForegroundColorAttributeName: [UIColor colorWithRed:214.0f/255.0f green:210.0f/255.0f blue:197.0f/255.0f alpha:1.0f], 
    NSShadowAttributeName: shadow] 
}]; 

Answer 2

UIColor *blue = [UIColor colorWithRed:64.0/255.0 
           green:119.0/255.0 
           blue:255.0/255.0 
           alpha:1.0]; 

NSShadow *shadow = [NSShadow.alloc init]; 
shadow.shadowColor = [UIColor clearColor]; 

NSDictionary *attributes = @{ 
           NSForegroundColorAttributeName: blue, 
           NSShadowAttributeName: shadow 
           }; 

[[UIBarButtonItem appearance] setTitleTextAttributes:attributes 
              forState:UIControlStateNormal];
