加载视图时的iPhone幻灯片动画

Question

How to perform a sliding animation when a view is being loaded in an iPhone application?

I have a ViewController in which I have subview. I want that the subview be loaded with an animation, sliding from the left to the right.

I got this code so far:

-(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

why not?

-(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];
}
