}
- (void)keyboardWillShow:(NSNotification*)notify
{
NSDictionary* info = [notify userInfo];
//kbSize键盘尺寸 (有width, height)
self.kbSize = [[info objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue].size;//键盘高度
NSLog(@"hight_hight:%f",self.kbSize.height);
CGRect currentFrame = self.view.frame;
CGFloat change =self.kbSize.height;
currentFrame.origin.y = currentFrame.origin.y - change ;
[UIView animateWithDuration:0.00000000001 animations:^{
self.view.frame = currentFrame;
}];
}
///键盘消失事件
- (void) keyboardWillHidden {
//视图下沉恢复原状
[UIView animateWithDuration:0.00000000001 animations:^{
self.view.frame = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height);
}];
[【你的TextFiled】 resignFirstResponder];

// 视图将要消失时,移除通知中心
-(void)viewWillDisappear:(BOOL)animated {
[[NSNotificationCenter defaultCenter] removeObserver:self];
}
