推荐答案
从iOS 7及更高版本开始:
NSShadow* shadow = [NSShadow new];
shadow.shadowOffset = CGSizeMake(0.0f, 1.0f);
shadow.shadowColor = [UIColor redColor];
[[UINavigationBar appearance] setTitleTextAttributes: @{
NSForegroundColorAttributeName: [UIColor greenColor],
NSFontAttributeName: [UIFont fontWithName:@"Helvetica" size:20.0f],
NSShadowAttributeName: shadow
}];
来自iOS 5及更高版本:
[[UINavigationBar appearance] setTitleTextAttributes: @{
UITextAttributeTextColor: [UIColor greenColor],
UITextAttributeTextShadowColor: [UIColor redColor],
UITextAttributeTextShadowOffset: [NSValue valueWithUIOffset:UIOffsetMake(0.0f, 1.0f)],
UITextAttributeFont: [UIFont fontWithName:@"Helvetica" size:20.0f]
}];
早于iOS 5:
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 400, 44)];
label.backgroundColor = [UIColor clearColor];
label.font = [UIFont boldSystemFontOfSize:20.0];
label.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.5];
label.textAlignment = UITextAlignmentCenter;
label.textColor =[UIColor whiteColor];
label.text=self.title;
self.navigationItem.titleView = label;
[label release];
