[英]ios navigation bar backgroundimage
I have the following code that is supposed to set the background image on my navigation bar. 我有以下代码,应该在导航栏上设置背景图像。
if ([self.navigationController.navigationBar respondsToSelector:@selector(setBackgroundImage:forBarMetrics:)] )
{
[self.navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:@"navigation-bar-background"] forBarMetrics:UIBarMetricsDefault];
}
else
NSLog(@"WTF");
It works on the iPad but not on an iPhone, on the iPhone it logs WTF ..... same result without the if statement. 它可以在iPad上运行,但不能在iPhone上运行,在iPhone上它记录WTF .....的结果相同,但没有if语句。 The iPhone I have is iPhone 4 running ios 6.0, the iPad is iPad 2 with ios 6.0 我拥有的iPhone是运行ios 6.0的iPhone 4,iPad是运行ios 6.0的iPad 2
Any help is appreciated. 任何帮助表示赞赏。
Thanks, 谢谢,
You could try this alternate old method 您可以尝试这种替代的旧方法
@implementation UINavigationBar (CustomImage)
- (void)drawRect:(CGRect)rect {
UIImage *image = [UIImage imageNamed: @"navigation-bar-background.png"];
[image drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)];
}
@end
