iAd定位于iphone 5和iphone 4问题

Question

I have a spritekit project where I want iAd to appear at the bottom of the screen. I used the storyboard to position it at the bottom of the screen. The only problem is if I put it at the bottom of an iPhone 4 screen it ends up in the middle of the iPhone 5 , and if I put it at the bottom of the iPhone 5 screen it doesn't show up on the 4.
I fixed this problem for a while by using banner.Center but when I change views the banner doesn't reload so it doesn't appear on the iPhone 4 screen.

    #pragma mark iAd Delegate Methods

-(void)bannerViewDidLoadAd:(ADBannerView *)banner{

    NSLog(@"SUCCESS");

    [UIView beginAnimations:nil context:NULL];

    [UIView setAnimationDuration:1];

    [banner setAlpha:1];

    [UIView commitAnimations];

    if (device == 4) {
        banner.center = CGPointMake(160, 455);
    }
    if (device == 5) {
        banner.center = CGPointMake(160, 543);
    }

    adIsThere = YES;
}


-(void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error{

    NSLog(@"ERROR");
    [UIView beginAnimations:nil context:NULL];

    [UIView setAnimationDuration:1];

    [banner setAlpha:0];

    [UIView commitAnimations];

    adIsThere = NO;


}

I found this link but when i click on the ad on the storyboard and on the size inspector, the autosizing part doesn't show up.... I think it has to do with the fact that its a SpriteKit project .

iad iPhone 5 Storyboard implementation

If you can help, Thanks!

Answer 1

Maybe instead of setting the position with an exact number, set it to the bottom of the screen minus the size of your banner ad.

CGFloat screenHeight = [[UIScreen mainScreen] bounds].size.height;
banner.center = CGPointMake(160, screenHeight - bannerView_.frame.size.height);

---

edit: maybe you can try to use constraints if you're using storyboard, right click drag from your iAd banner to the "view" and select "Bottom Space to Bottom Layout Guide"

Answer 2

Do something like this

if ([[UIScreen mainScreen] bounds].size.height==480)  //iPhone 4
{
 banner.center = CGPointMake(160, 455);
}
else if ([[UIScreen mainScreen] bounds].size.height==568) //iPhone 5
{
 banner.center = CGPointMake(160, 543);
}
