中/E文键盘切换高度监测

首先：宏定义

//判断是否是iphone5

#define iPhone5 ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(640, 1136),
[[UIScreen mainScreen] currentMode].size) : NO)

//监听键盘的宏定义

#define _UIKeyboardFrameEndUserInfoKey (&UIKeyboardFrameEndUserInfoKey != NULL ? UIKeyboardFrameEndUserInfoKey : @"UIKeyboardBoundsUserInfoKey")

然后，viewDiload里面写监听：

//键盘的监听事件，获取高度

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:)name:UIKeyboardWillShowNotification
object:nil];

最后在当前的controller里面写上如下方法：

//键盘事件

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

CGRect _keyboardRect = [[[notification userInfo] objectForKey:_UIKeyboardFrameEndUserInfoKey]CGRectValue];

//如下是在此方法中去改变tabview或者其他需要调整高度的view

myTabView.frame = CGRectMake(0, 40, 320, iPhone5 ? 460+88-85-_keyboardRect.size.height :460-85-_keyboardRect.size.height);

}

记住在dealloc中

[[NSNotificationCenterdefaultCenter]
removeObserver:selfname:UIKeyboardWillHideNotificationobject:nil];
[[NSNotificationCenterdefaultCenter]
removeObserver:selfname:UIKeyboardWillShowNotificationobject:nil];
否则会引起崩溃，因为当界面消失时会对nil对象sendMessage
