Why is UICollectionViewCell’s outlet nil?

How do you shrink a UIPickerView on the iPhone?

by

Actually, you can slightly shrink the whole UIPickerView by applying an affine transform to an enclosing view. For example: CGSize pickerSize = [pickerView sizeThatFits:CGSizeZero]; pickerTransformView = [[UIView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, pickerSize.width, pickerSize.height)]; pickerTransformView.transform = CGAffineTransformMakeScale(0.75f, 0.75f); [pickerTransformView addSubview:pickerView]; [self.view addSubview:pickerTransformView]; [pickerTransformView release]; will scale a picker to 75% of its original size by placing it … Read more

Apple Interface Builder: adding subview to UIImageView

You cannot add a subview to UIImageView in interface builder for reasons only known to Apple! You are right in saying that you can addSubview programmatically, but then, the overhead of setting autoresizing masks and placements of subviews should all be handled in code, which is cumbersome.

@IBDesignable crashing agent

by

Xcode’s Interface Builder requires that you implement both or neither initializers for @IBDesignable classes to render properly in IB. If you implement required init(coder aDecoder: NSCoder) you’ll need to override init(frame: CGRect) as well, otherwise “the agent will crash” as seen in the errors thrown by Xcode. To do so add the following code to … Read more
