Question

  if (! self.mainPage)
{ self.mainPage= [[MainGameDisplay alloc] initWithNibName:nil bundle:nil]; }
[self presentViewController: self.mainPage animated:YES completion:NULL];

[self.view addSubview:self.mainPage.view];
self.mainPage.view.frame = CGRectMake(568, 0, 568, 320);//(N = horizontal, N = vertical)
[UIView animateWithDuration:1.0f
                 animations:^{
                     //actual frame needed with an animation.
                     self.mainPage.view.frame = CGRectMake(0, 0, 568, 320);
                 }
                 completion:^(BOOL finished) {
                     //ENTER HERE ANYTHING TO RUN AFTER ANIMATION IS COMPLETED:
                     [self presentViewController: self.mainPage animated:NO completion:NULL];
                     //This will make the next page load correctly after the transition, otherwise you cannot. interact with anything.
                 }];

@property（strong）MainGameDisplay * mainPage;

在.h文件中声明。这段代码完美但只运行一次，如果我要转换到mainPage视图，返回并再次转换，它将在转换结束时崩溃。我已经玩了很多东西来解决这个问题，但它只是不起作用。

//First transition, A-Okay.
