模态解除后ViewController垂直位移20px:仅iOS4。包含示例代码

添加 [aViewControllerTwo setWantsFullScreenLayout:YES]; 给你的 - (void)flipToViewControllerTwo ViewControllerTwo *aViewControllerTwo = [[ViewControllerTwo alloc] initWithNibName:@"ViewControllerTwo" bundle:[NSBundle mainBundle]];

为了解决这个问题,您需要对出现偏移的视图控制器执行以下操作:添加一个帧,然后适当地设置该帧的位置。将此框架设置为ViewController的视图。

shiftedViewController* ShiftedViewController = [[ShiftedViewController alloc] init ];

CGRect theFrame = [shiftedViewController.view frame];
theFrame.origin.y = 20;
theFrame.origin.x=0;
[shiftedViewController.view setFrame: theFrame];



[self presentModalViewController:shiftedViewController          
                    animated:YES];
