加載視圖時的iPhone幻燈片動畫

Question

在iPhone應用程序中加載視圖時如何執行滑動動畫？

我有一個ViewController，其中有子視圖。 我希望子視圖加載有動畫，從左到右滑動。

到目前為止，我已經獲得了以下代碼：

-(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

為什么不？

-(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];
}
