iOS监测第三方键盘高度

- (void)keyboardWillShow:(NSNotification *)notification {

CGFloat curkeyBoardHeight = [[[notification userInfo] objectForKey:@"UIKeyboardBoundsUserInfoKey"] CGRectValue].size.height;

CGRect begin = [[[notification userInfo] objectForKey:@"UIKeyboardFrameBeginUserInfoKey"] CGRectValue];

CGRect end = [[[notification userInfo] objectForKey:@"UIKeyboardFrameEndUserInfoKey"] CGRectValue];

// 第三方键盘回调三次问题，监听仅执行最后一次

if(begin.size.height>0 && (begin.origin.y-end.origin.y>0)){

keyBoardHeight = curkeyBoardHeight;

[self showKeyboard:notification];

}
