加載視圖時的iPhone幻燈片動畫

Question

如何在iPhone應用程序中加載視圖時執行滑動動畫？

我有一個ViewController，我有子視圖。我希望子視圖加載一個動畫，從左向右滑動。

我走到這一步，這樣的代碼：

-(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

爲什麼不呢？

-(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]; 
}
