我有一個帶有xib文件的viewController B類，並且我將這個viewController添加到父視圖中。iOS從子視圖控制器隱藏statusBar
[Acontroller addChildViewController:self]; // self is B
[Acontroller.view addSubview:self.view];
我想要的是，當顯示B viewController時，隱藏應用程序的狀態欄。
如果我在A控制器使用方法：
-(BOOL)preferStatusBarHidden {
return YES;
}
狀態欄被隱藏，但我想這樣做，只是從B控制器，但它不工作。
我該怎麼辦？
謝謝。

爲什麼使用addChildViewController來代替推送或呈現。 HTTP：//計算器。com/a/8084188/1405008請參閱此更多信息 – CoolMonster
