出现在所有中的文本的外观UINavigationBars
,请在application:didFinishLaunchingWithOptions:
[[UIBarButtonItem appearanceWhenContainedIn:[UINavigationBar class], nil] setTitleTextAttributes:
@{UITextAttributeTextColor:[UIColor blackColor],
UITextAttributeTextShadowOffset:[NSValue valueWithUIOffset:UIOffsetMake(0, 1)],
UITextAttributeTextShadowColor:[UIColor whiteColor],
UITextAttributeFont:[UIFont boldSystemFontOfSize:12.0]
}
forState:UIControlStateNormal];
更新:iOS7 友好版本
NSShadow *shadow = [[NSShadow alloc] init];
shadow.shadowOffset = CGSizeMake(0.0, 1.0);
shadow.shadowColor = [UIColor whiteColor];
[[UIBarButtonItem appearanceWhenContainedIn:[UINavigationBar class], nil]
setTitleTextAttributes:
@{NSForegroundColorAttributeName:[UIColor blackColor],
NSShadowAttributeName:shadow,
NSFontAttributeName:[UIFont boldSystemFontOfSize:12.0]
}
forState:UIControlStateNormal];
