修改状态栏颜色

解决个别vc中状态栏字体颜色不同的办法

1、在info.plist中，将View controller-based status bar appearance设为NO.

2、在app delegate中：

[UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleLightContent;

3、在个别状态栏字体颜色不一样的vc中

-(void)viewWillAppear:(BOOL)animated{

[UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleDefault;

}

-(void)viewWillDisappear:(BOOL)animated
{

[super viewWillDisappear:animated];

[UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleLightContent;

}
