1、輸入框監(jiān)聽UIControlEventEditingDidBegin事件，當(dāng)用戶開始輸入時，將整個view上移。

輸入框監(jiān)聽UIControlEventEditingDidEnd事件，當(dāng)用戶結(jié)束輸入時，將整個view下移，恢復(fù)到原位置。

[textfield addTarget:self action:@selector(textFieldDidBeginEditing:) forControlEvents:UIControlEventEditingDidBegin];

[textfield addTarget:self action:@selector(textFieldDidEndEditing:) forControlEvents:UIControlEventEditingDidEnd];

通過tag值來確定每個textfield是否響應(yīng)

2//鍵盤監(jiān)聽

[[NSNotificationCenter

defaultCenter] addObserver:self

selector:@selector(keyboardWillChangeFrame:)

name:UIKeyboardWillChangeFrameNotification object:nil];

- (void)keyboardWillChangeFrame:(NSNotification *)notification

{

CGRect isUpflag;

[[[notification userInfo] objectForKey:UIKeyboardFrameBeginUserInfoKey] getValue:&isUpflag];

NSDictionary *info = [notification userInfo];

CGSize kbSize = [[info objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue].size;

[UIView animateWithDuration:0.25 animations:^{

showView.center = CGPointMake(showView.center.x, self.view.center.y - kbSize.height);

}];

}

kbSize.height可以獲取鍵盤的高度
