状态栏颜色修改

//设置状态栏颜色

- (void)setStatusBarBackgroundColor:(UIColor *)color {

UIView *statusBar = [[[UIApplication sharedApplication] valueForKey:@"statusBarWindow"] valueForKey:@"statusBar"];

if ([statusBar respondsToSelector:@selector(setBackgroundColor:)]){

statusBar.backgroundColor = color;

}

}

然后调用

- (void)viewWillAppear:(BOOL)animated {

[super viewWillAppear:animated];

[self setStatusBarBackgroundColor:[UIColor redColor]];

}

本来是透明的，就会变成红色。
