IOS开发实用小技巧(持续更新)

1.设置电池栏

didFinishLaunchingWithOptions: 

//MARK :-设置电池栏(状态栏)
    //设置颜色(亮色/白色)
    application.statusBarStyle = UIStatusBarStyleLightContent;
    //启动时隐藏
    application.statusBarHidden = NO;

iOS7开始状态栏的设置权交给了当前界面

隐藏状态栏

- (BOOL)prefersStatusBarHidden {
    return YES;
}

修改状态栏的颜色

- (UIStatusBarStyle)preferredStatusBarStyle {
    return UIStatusBarStyleLightContent;
}
