iphone - 加载视图时的iPhone幻灯片动画

Question

在 iPhone 应用程序中加载视图时如何执行滑动动画？

我有一个 ViewController，其中有子视图。我希望子视图加载动画，从左向右滑动。

到目前为止我得到了这个代码：

-(void) showAnimation{

    [self.view addSubview:geopointView]
    geopointView.frame = CGRectMake(20,150,550,200)// somewhere offscreen, in the direction you want it to appear from
    [UIView animateWithDuration:10.0 
         animations:^{
             geopointView.frame = CGRectMake(20,150,550,200)// its final location
    }];
}

Answer 1

为什么不？

-(void) showAnimation{
[self.view addSubview:geopointView]
geopointView.frame = CGRectMake(-200,150,550,200)// just set a different frame
[UIView animateWithDuration:10.0 
             delay:0.0
             options:UIViewAnimationCurveEaseOut
             animations:^{
                 geopointView.frame = CGRectMake(20,150,550,200)// its final location
             }
             completion:nil];
}
