Question

我正在尝试使用shouldAutorotateToInterfaceOrientation方法加载视图，但我遇到了问题。当设备作为横向运行时，我想显示主视图本身，当设备是纵向时，加载自定义UIView。

这是我的代码：

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    // Return YES for supported orientations

        if ((interfaceOrientation == UIInterfaceOrientationLandscapeLeft)|| (interfaceOrientation == UIInterfaceOrientationLandscapeRight))

            //doesn't show main view !!
            self.view;


        else if ((interfaceOrientation == UIInterfaceOrientationPortrait) || (interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown))

            //works fine ! 
            self.view = portraitView;


      return YES;

}

我想通了!!!!只需在方法

上使用模态调用视图

- (void) mainView {
    screenTestViewController *mv = [[screenTestViewController alloc]initWithNibName:@"screenTestViewController" bundle:nil];
    [self presentModalViewController:mv animated:NO];

}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {

    // Return YES for supported orientations 

    if ((interfaceOrientation == UIInterfaceOrientationLandscapeLeft)|| (interfaceOrientation == UIInterfaceOrientationLandscapeRight))

        [self mainView];

您应该将自定义UIView推送到：willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation duration:(NSTimeInterval)duration

使用shouldAutorotateToInterfaceOrientation加载mainView
