需要有关同时使用UIPickerView和UIActionSheet的新手指南（仅在点击文本框时才显示pickerview）

Question

I have been searching for days on on how I can use a pickerview on my textfield... I am very new to Ios programming and I have been searching the web for snippets of code that I can use on my program..

Basically this is just what I want: I have a one of my textfield that ask for which Equipment type.. there is only 4 items to select on. I want the program to show the picker view when they tap the equiptextfield and fill it with the item that they selected from the picker view.. then the picker view should be dismissed or go to the next field.

I found out online that the best way to do this is to use UIActionSheet to show/hide the pickerview only when that textfield was selected.

I need to know what I have to add on these items: -my nib file(currently it has 1 view with a scrollview under it and all the fields is on it) View -scroll View -my textfields under it...

-my header file... im really a noob so I really need to ask for the code

-my implementation file.. same as the header, I need the code please

Please dont think I didnt do my search because I did and there is just so much stuff online that its hard to figure out which to use, and those that I tried gave me errors.

thank you so much for any help anyone can provide.

Apple provides a good example of UIKit's controls. UICatalog

This sample is a catalog exhibiting many views and controls in the UIKit framework, along with their various properties and styles.

If you need code to create specific UI controls or views, refer to this sample and it should give you a good head start in building your user interface. In most cases you can simply copy and paste the code snippets you need.

Try. Do not be afraid to fail. Errors are experience too.

Btw, why are you using UITextField for such tasks? I suppose, the better way to select the one option from four is to use UISegmentedControl with 4 segments.
