Question

我的应用程序中有这个代码来为viewcontroller进行转换

SecondViewController *second = [[SecondViewController alloc]initWithNibName:@"SecondViewController" bundle:nil];
    [self.view addSubview:second.view];
    [second.view setFrame:CGRectMake(320, 0, 320, 480)];

    [UIView beginAnimations:nil context:nil];
    [UIView setAnimationDuration:0.40]; //the double represents seconds
    [UIView setAnimationDelegate:self];
    [UIView setAnimationCurve:UIViewAnimationCurveEaseOut];
    [second.view setFrame:CGRectMake(0, 0, 320, 480)];
    [UIView commitAnimations];

它工作正常; 但在第二个视图控制器内我有这个代码消失这个viewcontroller

[UIView beginAnimations:nil context:nil];
    [UIView setAnimationDuration:0.40]; //the double represents seconds
    [UIView setAnimationDelegate:self];
    [UIView setAnimationCurve:UIViewAnimationCurveEaseOut];
    [self.view setFrame:CGRectMake(320, 0, 320, 480)];
    [UIView commitAnimations];

它运行正常，但是什么是释放它的方式，我可以在哪里释放我在调用它时分配的第二个？如果我写[self.view removeFromSuperView] ??它被释放了吗？

您需要将其从superView中删除，然后释放您在代码中分配的SecondViewController。

SecondViewController *second = [[SecondViewController alloc]initWithNibName:@"SecondViewController" bundle:nil];

因此，既然您拥有此对象，则需要释放它。所以在隐藏第二个视图并将其从superView中删除之后的某个地方，你需要释放它......

[second release];
