ios 含有textfield的viewcontroller隨鍵盤彈起而改變位置

標籤：

首先實現 設定代理，self.textfield.delegate = self;

具體實現代碼：-(void)textFieldDidBeginEditing:(UITextField *)textField{    NSTimeInterval animationDuration = 0.30f;    [UIView beginAnimations:@"ResizeForKeyboard" context:nil];    [UIView setAnimationDuration:animationDuration];    if ([UIScreen mainScreen].bounds.size.width>320) {        //將視圖的Y座標向上移動，以使下面騰出地方用於軟鍵盤的顯示        self.view.frame = CGRectMake(0.0f, -200.0f, self.view.frame.size.width, self.view.frame.size.height);//64-216        [UIView commitAnimations];    }    else{        self.view.frame = CGRectMake(0.0f, -170.0f, self.view.frame.size.width, self.view.frame.size.height);        [UIView commitAnimations];    }}-(void)textFieldDidEndEditing:(UITextField *)textField{    //滑動效果    NSTimeInterval animationDuration = 0.30f;    [UIView beginAnimations:@"ResizeForKeyboard" context:nil];    [UIView setAnimationDuration:animationDuration];        //恢複螢幕    self.view.frame = CGRectMake(0.0f, 0.0f, self.view.frame.size.width, self.view.frame.size.height);//64-216        [UIView commitAnimations];}
