[英]I want to change UIButton Image when tapped on it
我在CollectionViewController的標題中有2個按鈕。 當我點擊其中一個時,我正在使用UIControlState - > .normal .selected更改此按鈕的圖像。
override func viewDidLoad() {
super.viewDidLoad()
collectionView.delegate = self
collectionView.dataSource = self
engSwitchButton.setImage(#imageLiteral(resourceName: "abc"), for: .normal)
geoSwitchButton.setImage(#imageLiteral(resourceName: "abg"), for: .normal)
engSwitchButton.setImage(#imageLiteral(resourceName: "abc2"),for: UIControlState.selected)
geoSwitchButton.setImage(#imageLiteral(resourceName: "abg2"), for: UIControlState.selected)
engSwitchButton.tag = Language.english.rawInt
geoSwitchButton.tag = Language.georgian.rawInt
}
@IBAction func languageSwitchTapped(_ sender: UIButton) {
sender.isSelected = !sender.isSelected
selectedLanguage = Language(rawInt: sender.tag)!
collectionView.reloadData()
}
我想要首先點擊的按鈕,當我通過點擊它改變2d按鈕的狀態時,回到.normal狀態。
要在點擊時更改按鈕圖像,您應該使用UIControlState.highlighted
。
所以改變:
engSwitchButton.setImage(#imageLiteral(resourceName: "abc2"),for: UIControlState.selected)
geoSwitchButton.setImage(#imageLiteral(resourceName: "abg2"), for: UIControlState.selected)
對此:
engSwitchButton.setImage(#imageLiteral(resourceName: "abc2"),for: UIControlState.highlighted)
geoSwitchButton.setImage(#imageLiteral(resourceName: "abg2"), for: UIControlState.highlighted)
@IBAction func yourFirstButton(_ sender: Any) {
firstButton.setImage(UIImage(named: "yourButtonPressedImage")!, for: .normal)
secondbutton.setImage(UIImage(named: "yourNormalImage")!, for: .normal)
}
在你的第二個按鈕@IBAction方法只需切換按鈕的圖像
@IBAction func yourSecondButton(_ sender: Any) {
secondButton.setImage(UIImage(named: "yourButtonPressedImage")!, for: .normal)
firsBbutton.setImage(UIImage(named: "yourNormalImage")!, for: .normal)
}
