自定义导航栏背景图片和颜色

转自：/article/8380099.html

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

[java] view
plaincopyprint?

UINavigationBar *navBar = self.navigationController.navigationBar;

#define kSCNavBarImageTag 10

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

{

//if iOS 5.0 and later

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

}

else

{

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

if (imageView == nil)

{

imageView = [[UIImageView alloc] initWithImage:

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

[imageView setTag:kSCNavBarImageTag];

[navBar insertSubview:imageView atIndex:0];

[imageView release];

}

}



更改颜色，可以使用tintColor属性
