选择UITextField时如何显示UIPickerView [英] How to Show UIPickerView when selecting UITextField

问题描述

以下是我到目前为止所做的屏幕截图:

Here is a screenshot of what I did till now:

所以我想做的是，当您选择选择名称"文本字段时，我需要一个选择器来显示，并输入@"Jack".

So what I am trying to do is when you select "pick a name" Textfield I need a Picker to show up, with the input @"Jack".

推荐答案

它将为您工作..我已经对其进行了编辑.为此，您必须为文本字段设置委托.并在NIb文件中创建UIPIckrView.

it will work for you .. i have edited it .and for that you have to set delegate for textfield. and create a UIPIckrView in NIb file.

- (BOOL) textFieldShouldBeginEditing:(UITextView *)textView
{
    pickrView.frame = CGRectMake(0, 500, pickrView.frame.size.width,    pickrView.frame.size.height);
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:.50];
    [UIView setAnimationDelegate:self];
    pickrView.frame = CGRectMake(0, 200, pickrView.frame.size.width, pickrView.frame.size.height);
    [self.view addSubview:pickrView];
    [UIView commitAnimations];
    return NO;
}
