UIPickerView作为UITextField的inputView [英] UIPickerView as inputView of UITextField

问题描述

我已经阅读了很多关于如何使用 UIPickerView 作为我的<$ c的 inputView $ C>的UITextField 。问题是，当我点击 UITextField 时，我可以调用 UIPickerView 。但是，我的应用程序始终加载显示的 UIPickerView 。我已经尝试在 viewDidLoad 中更改 myownpickerview.hidden = YES; ，但是当我点击的UITextField 。它不会显示，如果我多次单击，调试器会显示错误。

I've read a lot about how I can use a UIPickerView as the inputView of my UITextField. The thing is, I am able to call the UIPickerView when I tap on the UITextField. However, my app always loads with the UIPickerView shown. I have already tried changing the myownpickerview.hidden = YES; in viewDidLoad, but this causes problems when I click on the UITextField. It won't show up, and if I click multiple times, the debugger shows that there would be an error.

有人能指出我正确的方向吗？我只想在点击 UITextField

Can anyone point me in the right direction? I only want the UIPickerView shown after I tap on the UITextField

我还在开发我的第一款iOS应用程序。请耐心等待。谢谢=）

I'm still working on my first ever iOS app. Please be patient. Thank you =)

推荐答案

试试这个，它运行正常，把它放在viewdidload中。

Try this, it works fine, put it in viewdidload.

yourpicker = [[UIPickerView alloc] initWithFrame:CGRectMake(0, 50, 100, 150)];
    [yourpicker setDataSource: self];
    [yourpicker setDelegate: self];
    yourpicker.showsSelectionIndicator = YES;
    self.yourtextfield.inputView = yourpicker;

不 [self.view addSubview： yourpicker]; 这个
