UITextField更改事件不会针对语音或粘贴的输入触发

Question

在Xcode 6.2中，当尝试使用键盘上的“语音”按钮输入文本时触发UITextField“ Edited Changed”事件或“ Value Changed”事件触发时，它完美地使用了键入的输入， 但不适用于粘贴或输入的输入使用语音识别 。

Answer 1

You might want to use or hack another delegate shouldChangeCharactersInRange, it get called when text is changing

- (BOOL) textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
{    
    // Do your stuff or raise a event when it is Pasted.
    // You can figure out if isPasted from the pattern of range.

    return YES;
}
