Autodetect constrained NSButton text inserts

I'm on OSX (not iOS), Xcode 8.2, Objective-C

I have two constrained buttons. Both buttons have centered headings and both have the same width (via constraints). No, when it comes to a different language, the buttons get wider to fit longer text. But I would like to have some space between the border of the button and the text. IB insert options do not exist for NSButtons and I have not found any equivalent solutions.

Any help is appreciated

You have to override the readinly intrinsicContentSize property the same as in UILabel

Here is an example of overriding NSButton with properties that you can set in the xib / storyboard file using the attribute pointer



//CustomButton.h file

@interface CustomButton : NSButton

@property (nonatomic, assign) IBInspectable CGFloat horizontalPadding;
@property (nonatomic, assign) IBInspectable CGFloat verticalPadding;

@end

//CustomButton.m file

@implementation CustomButton

- (NSSize) intrinsicContentSize{
    CGSize size = [super intrinsicContentSize];
    size.width += self.horizontalPadding;
    size.height += self.verticalPadding;
    return size;
}

@end

Happy coding 👨💻

Swift 4



class Button: NSButton {

    @IBInspectable var paddingLeft   : CGFloat = 0
    @IBInspectable var paddingTop    : CGFloat = 0
    @IBInspectable var paddingBottom : CGFloat = 0
    @IBInspectable var paddingRight  : CGFloat = 0

    override var alignmentRectInsets: NSEdgeInsets {
        var insets    = super.alignmentRectInsets
        insets.left   = -self.paddingLeft
        insets.top    = -self.paddingTop
        insets.right  = -self.paddingRight
        insets.bottom = -self.paddingBottom
        return insets
    }
}
