Status bar color changed when change UINavigationBar appearance backgroundimage

问题

I use this line of code to change navigation bar background:

    [[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"image.png"] forBarMetrics:UIBarMetricsDefault];

in iOS6, it works, but in iOS5, background of the status bar is changed too, as shown in this image:

how does this happen. Thanks in advance.

One more thing, I just want to change the color of UINavigationBar, so I used this code:

[[UINavigationBar appearance] setTintColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"image.png"]]];

It works in iOS6 quite well, but does not in iOS5. What is the reason?

回答1:

You can use this one to set your status bar

 [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackTranslucent animated:YES];

So status bar colour will be black and font colour will be white..
