dismissModalViewController隐藏状态栏后面的父视图 [英] dismissModalViewController Hides the parent view behind status bar

问题描述

我这里有一个非常奇怪的问题。我正在使用一个现有的模态视图控制器来在ViewController上显示我的MFMailComposer ViewController，它放在导航栏中。

I have a very strange issue here. I am using a present modal view controller to display my MFMailComposer ViewController on top of a ViewController which is placed with in a Navigation Bar.

[self presentModalViewController：emailviewController animated：YES];

要隐藏，我使用...

to hide , I use ...

-(void) mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error
{

    [self dismissModalViewControllerAnimated:YES];
}

一切正常但当我解雇我的MailComposer时，原始视图控制器隐藏在状态栏 。

Everything works fine but when I dismiss my MailComposer the original view controller hides behind the status bar .

我尝试使用setFrame方法将视图偏移量修改为10，但它无法正常工作。 （这在模态视图控制器出现和解除之前和之后都很累）

I have tried to modify view offset by 10 using setFrame method but It din't worked . (this is tired before and after the modal view controller is presented and dismissed )

我试过暂时隐藏状态栏但没有工作。

I have tried by hiding status bar temporarily but didn't worked.

我已经尝试过self.navigationcontroller presentmodalviewcontrolle但是也没有用...

I have tried self.navigationcontroller presentmodalviewcontrolle but that didn't worked too...

任何想法或建议都将受到高度赞赏

Any ideas or suggestions would be highly appreciated

编辑：大多数人都给我一个手动修改偏移量的建议。
好​​吧，这不起作用。因为如果我在原始viewcontroller方法的viewDidLoad / viewWillapper中执行此操作，那么它会在当前模态视图控制器之前移动我的视图，而在我加载模态视图控制器之后它变得正常。

edited : Most of the people give me a suggestion to modify the offset manually. Well that does not work . Because if I do that in my viewDidLoad/viewWillapper of the original viewcontroller method then It shifts my view before the present modal view controller whereas after I load the modal view controller It becomes normal.

• （void）viewDidAppear：（BOOL）animated {
  CGRect frame = self.navigationController.view.frame;
  frame.origin.y = 20;
  self.navigationController.view.frame = frame;
  }

推荐答案

尝试将其放入ViewDidAppear：

Try putting this in ViewDidAppear:

[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleDefault];

最糟糕的情况是，如果只在模态视图控制器被解除后才发生，则声明一个布尔值在.h中的afterFirstLaunch并将其放入viewDidAppear：

Worst case, if it is always happening only after the modal view controller is dismissed, declare a boolean for afterFirstLaunch in the .h and put this in viewDidAppear:

if(afterFirstLaunch){
      CGRect frame = self.navigationController.view.frame;
      frame.origin.y = 20;
      self.navigationController.view.frame = frame;
}
else {
      afterFirstLaunch = true;
 }
