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

@IBDesignable crashing agent

Xcode’s Interface Builder requires that you implement both or neither initializers for @IBDesignable classes to render properly in IB.

To do so add the following code to … Read more
