iPhone开发 自定义 uinavgationbar

谢谢lamo的提醒，这个5.0确实无效。

//添加5.0下需加入的代码

    if ([self.navigationController.navigationBar respondsToSelector:@selector( setBackgroundImage:forBarMetrics:)]){
        [self.navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:@"check_yes.png"] forBarMetrics:UIBarMetricsDefault];
        [self.navigationController.navigationBar setTintColor:[UIColor redColor]];
    } 

 

 

CustomNavgationBar.m

@implementation UINavigationBar (UINavigationBarCategory)

- (void)drawRect:(CGRect)rect {
    //颜色填充
    //UIColor *color = [UIColor greenColor];
    //CGContextRef context = UIGraphicsGetCurrentContext();
    //CGContextSetFillColor(context, CGColorGetComponents( [color CGColor]));
    //CGContextFillRect(context, rect);
    //self.tintColor = color;
    //图片填充
    UIColor *color = [UIColor colorWithRed:46.0f/255.0f green:87.0f/255.0f blue:29.0f/255.0f alpha:1.0f];
    UIImage *img    = [UIImage imageNamed: @"button.png"];
    [img drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)];
    self.tintColor = color;
    
}
@end

CustomNavgationBar.h

- (void)drawRect:(CGRect)rect;

无需引用，在有navbar的地方自动会改变
