iOS:获取正确的ThirdPart键盘高度 [英] iOS: Get correct height of thirdPart keyboard

问题描述

自从iOS8起，出现了许多ThirdPart键盘显示，我想在显示时获得键盘高度

Since iOS8, many thirdPart keyboard shows, i want to get the keyboard height when it show

NSDictionary* info = [aNotification userInfo]; CGSize kbSize = 
[[info objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue].size;

但是我可以获取系统键盘的高度，但是却不能获取ThirdKey键盘(例如SouGouKeyboard)，它返回0而不是如何获取正确的高度?

however i can get the height of system keyboard, but can't get a thirdPart keybord(such as SouGouKeyboard),it return 0 instead how to get the correct height?

它返回: { UIKeyboardAnimationCurveUserInfoKey = 7; UIKeyboardAnimationDurationUserInfoKey = "0.25"; UIKeyboardBoundsUserInfoKey = "NSRect: {{0, 0}, {320, 0}}"; UIKeyboardCenterBeginUserInfoKey = "NSPoint: {160, 568}"; UIKeyboardCenterEndUserInfoKey = "NSPoint: {160, 568}"; UIKeyboardFrameBeginUserInfoKey = "NSRect: {{0, 568}, {320, 0}}"; UIKeyboardFrameEndUserInfoKey = "NSRect: {{0, 568}, {320, 0}}"; }

it returns : { UIKeyboardAnimationCurveUserInfoKey = 7; UIKeyboardAnimationDurationUserInfoKey = "0.25"; UIKeyboardBoundsUserInfoKey = "NSRect: {{0, 0}, {320, 0}}"; UIKeyboardCenterBeginUserInfoKey = "NSPoint: {160, 568}"; UIKeyboardCenterEndUserInfoKey = "NSPoint: {160, 568}"; UIKeyboardFrameBeginUserInfoKey = "NSRect: {{0, 568}, {320, 0}}"; UIKeyboardFrameEndUserInfoKey = "NSRect: {{0, 568}, {320, 0}}"; }

推荐答案

您可以尝试此方法

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWasShown:)name:UIKeyboardDidShowNotification    
    object:nil];

 - (void)keyboardWasShown:(NSNotification *)notification
{
  CGSize keyboardSize = [[[notification userInfo]objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
  int height = MIN(keyboardSize.height,keyboardSize.width);
  int width = MAX(keyboardSize.height,keyboardSize.width);
}
