Question

我写了一个基本的双视图应用程序，每按一次按钮就会从一个视图切换到另一个视图。

但出于某种原因，当我在模拟器上运行它时，两个视图总是在MainWindow.xib视图上方几个像素，始终位于它之上。奇怪的是，当我在视图之间切换时没有动画。

问题是什么???

这就是我在 AppDelegate.m

中的内容

-(void)switchView:(UIView *)view1 toView:(UIView *)view2{

    [UIView beginAnimations:@"Animation" context:nil];
    [UIView setAnimationDuration:1.75];
    [UIView setAnimationTransition:UIViewAnimationOptionTransitionFlipFromLeft forView:self.window cache:YES];
    [view1 removeFromSuperview];
    [window addSubview:view2];
    [UIView commitAnimations];
}

嗨试试这个，

 -(void)switchView:(UIView *)view1 toView:(UIView *)view2
    {
        view2.frame = self.window.bounds;
        [UIView beginAnimations:nil context:NULL];
        [UIView setAnimationDelegate:self];
        [UIView setAnimationDuration:0.5f];
        [UIView setAnimationBeginsFromCurrentState:YES];
        [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:view2 cache:NO];
        [view1 removeFromSuperview];
        [window addSubview:view2];
        [UIView commitAnimations];
    }

也试试这个

[UIView transitionWithView:view2 duration:0.5
        options:UIViewAnimationTransitionFlipFromLeft //change to whatever animation you like
        animations:^ { [window addSubview:view2]; }
        completion:nil];

     Can you post some code regarding this .Because if you click on Segment change 
it will change the Views.IF you take two views on same interface Builder.
        Try out this

    IBOutlet UIView *viewA;
    IBOutlet UIView *viewB;

    in .m file 



-(IBAction)SegmentChange
{
    if(segment.selectedSegmentIndex==0)
    {
        viewA.hidden=NO;
        viewB.hidden=YES;


    }

    else if(segment.selectedSegmentIndex==1)
    {
        [self.View addSubview:viewB];
        viewA.hidden=YES;
        viewB.hidden=NO;

    }

}
