自定义UINavigationBar背景图片和颜色

首先准备导航栏背景图片，大小 320x44, @2x文件大小640x88，iOS5以后更改背景图片较简单

01	UINavigationBar *navBar = self.navigationController.navigationBar;

02

03	#define kSCNavBarImageTag 10

04	if([navBar respondsToSelector:@selector(setBackgroundImage:forBarMetrics:)])

05

{

06	//if iOS 5.0 and later

07	[navBar setBackgroundImage:[UIImage imageNamed:@"navbar1.png"] forBarMetrics:UIBarMetricsDefault];

08

}

09

else

10

{

11	UIImageView *imageView = (UIImageView *)[navBar viewWithTag:kSCNavBarImageTag];

12	if(imageView == nil)

13

{

14	imageView = [[UIImageView alloc] initWithImage:

15	[UIImage imageNamed:@"navbar1.png"]];

16	[imageView setTag:kSCNavBarImageTag];

17	[navBar insertSubview:imageView atIndex:0];

18	[imageView release];

19

}

20

}

 更改颜色，可以使用tintColor属性

 

1	myBar.tintColor = [UIColor greenColor];
