    [array addObject:@"Apple"];
    [array addObject:@"Samsung"];
    [array addObject:@"Sony"];

    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

#pragma mark collection view methods


-(NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView{
    return 1;
}
-(NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section{
    return [array count];
}
-(UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath{

    UICollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"Cell" forIndexPath:indexPath];
    UILabel *label = (UILabel *)[cell viewWithTag:100];
    label.text = [array objectAtIndex:indexPath.row];
    [cell.layer setBorderWidth:2.0f];
    [cell.layer setBorderColor:[UIColor whiteColor].CGColor];
    //[cell.layer setCornerRadius:50.0f];

    return cell;

}
@end

Did you add Auto Layout constraints in your `UICollectionView` ? — Raptor, Feb 17 '15 at 06:36
RTFM. Search "Auto Layout" in Google or Apple Developer Portal. — Raptor, Feb 17 '15 at 06:37
If you know the perfect material regarding this then can you send a page link. — Bhargav, Feb 17 '15 at 06:39
Stack Overflow is NOT a place to search for tutorial. Google is. — Raptor, Feb 17 '15 at 06:40

Use auto layout or autoresizing to make compatible for every devices. for auto layout go through this link.

http://captechconsulting.com/blog/jack-cox/ios-7-tutorial-series-auto-layout-xcode-5

for autoresizing

Autoresizing masks programmatically vs Interface Builder / xib / nib

and if you add component pragmatically then check screen width for every device.

[ [ UIScreen mainScreen ] bounds ].size.width

Just go to images.xcassets, right clicking in the navigator area, add launchImage. Then select your project (or target), go to general-->App Icons and Launch images and set Launch Images Source as Launch Image and most importantly, set Launch Screen file blank.

The app would now work well in iphone 6 simulator too. enter image description here

PS: I also had the same problem. Solved it my self. See enter link description here

Just go to images.xcassets, right clicking in the navigator area, select Appicon. Then check the ios 7 and later sizes. if iOS 8 and later sizes selected then remove that check box. By doing that you will able to get your application run in all resolution iphone 4s,5 and 6.

See the screen shot.
