//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; } }

• (void)viewDidLoad { [super viewDidLoad];

  [self setStatusBarBackgroundColor:[UIColor redColor]]; self.view.backgroundColor = [UIColor yellowColor]; }

//设置字的颜色

• (UIStatusBarStyle)preferredStatusBarStyle{ return UIStatusBarStyleLightContent; }

1.plist设置statusBar

在plist里增加一行 UIStatusBarStyle(或者是“Status bar style”也可以)，这里可以设置两个值，就是上面提到那两个 UIStatusBarStyleDefault 和 UIStatusBarStyleLightContent 2.程序代码里设置statusBar [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent]; 3.在plist文件中添加 View controller-based status bar appearance ＝ NO。
