Question

我有一个滚动视图设置，当键盘显示时（文本字段处于活动状态）向上推视图但它似乎在模拟器中完美地工作，并且在实际设备上不时地工作。 / p>

func keyboardWasShown(notification: NSNotification){

    self.scrollView.isScrollEnabled = true
    var info = notification.userInfo!
    let keyboardSize = (info[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue.size
    let contentInsets : UIEdgeInsets = UIEdgeInsetsMake(0.0, 0.0, keyboardSize!.height, 0.0)

    self.scrollView.contentInset = contentInsets
    self.scrollView.scrollIndicatorInsets = contentInsets

    var aRect : CGRect = self.view.frame
    aRect.size.height -= keyboardSize!.height
    if let activeField = self.activeField {
        if (!aRect.contains(activeField.frame.origin)){
            self.scrollView.scrollRectToVisible(activeField.frame, animated: true)

        }
    }

}

Answer 1

The answer is no, it should work both in simulator and device.

But i would advise you instead of creating a lot of logic to understand when the view should go up or down to use this framework instead:

KeyBoard Manager

scrollView.scrollRectToVisible（）仅适用于模拟器？
