How to link ibOutlet from subview to custom UIView Class in storyboard xcode
Here is a solution:
1) Type an IBOutlet by hands in your header file, example:
@property (strong, nonatomic) IBOutlet ProgressBarElementView *targetProgressElement;2) Drag the pin from the code to the element in document outline zone
I have the same problem.. I saw that if you add the custom class to the root view in the view controller, it will work.. In your case this is the initial View, listed under Bottom Layout Guide
But there must be a better way
To overcome XCode stubborness, especially when you need to hook up different enums from UIControlEvent than UIControlEventTouchUpInside, I'd rather use code directly from within the custom view class:
SWIFT
button.addTarget(self, action:#selector(ClassName.handleRegister(sender:)), for: .touchDragExit)OBJECTIVE-C
[self.button addTarget:self action: @selector(buttonTouchDragExitAction:) forControlEvents:UIControlEventTouchDragExit];One might include such code in awakeFromNib or viewDidLoad or where it best suits.
