Question

I am using the following codes to add two button to self.navigationItem.rightBarButtonItems, and I think in iOS7, the space between two buttons are too wide, is there a way

Answer 1

I gave up with fighting this bug, and came up with the following extension:

import UIKit

extension UIBarButtonItem {

    convenience init(buttonImage: UIImage?, target: Any?, action: Selector?) {
        let button = UIButton(type: .system)
        button.frame = CGRect(origin: CGPoint.zero, size: buttonImage != nil ? buttonImage!.size : CGSize.zero)
        button.setImage(buttonImage, for: .normal)

        if let action = action {
            button.addTarget(target, action: action, for: .touchUpInside)
        }

        self.init(customView: button)
    }

    public func updateButton(image: UIImage?) {
        if let button = self.customView as? UIButton {
            button.setImage(image, for: .normal)

            let size = image != nil ? image!.size : CGSize.zero
            let frame = button.frame
            button.frame = frame.insetBy(dx: ceil((frame.size.width - size.width) / 2), dy: ceil((frame.size.height - size.height) / 2))
        }
    }
}
