我已經創建了需要可拖動一個自定義的UITextView的,這是我的代碼使用方法:可拖動的UITextView不響應
class DraggableView: UITextView {
var lastLocation:CGPoint = CGPointMake(0, 0)
override init(frame: CGRect, textContainer: NSTextContainer?) {
super.init(frame: frame, textContainer: textContainer)
// Initialization code
var panRecognizer = UIPanGestureRecognizer(target:self, action:"detectPan:")
self.gestureRecognizers = [panRecognizer]
self.editable = true
self.selectable = true
self.backgroundColor = UIColor.redColor()
}
required init(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
func detectPan(recognizer:UIPanGestureRecognizer) {
var translation = recognizer.translationInView(self.superview!)
self.center = CGPointMake(lastLocation.x + translation.x, lastLocation.y + translation.y)
}
override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {
// Promote the touched view
//self.superview?.bringSubviewToFront(self)
// Remember original location
lastLocation = self.center
}
}
的顯示出來,但問題是,我不能寫任何東西,或與之互動它,我只能移動它。
什麼問題?
做這件事絕對不是那麼簡單,我在ObjC有答案,但我沒有時間翻譯它,但它比你在那裏有更多的參與。 – Loxx
