How to replace a keyboard with a Uipickerview?

Question

I have a program, that an excerpt from the form, in case a UITextField, that needs to be filled in. But instead of a keyboard, I need a UIPickView, that already has the options for filling.

Then the moment the user starts the edition of this UITextField, I need that instead of the keyboard, a UIPickView.

The program is for iOS, using Objective-C.

Answer 1

Just add your own UIPickerView on the property inputView of UITextField. Supposing you have something like that when you start your View Controller:

_picker = [[UIPickerView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, self.view.frame.size.width, 270.0f)];
[_picker setDelegate:self];
[_picker setDataSource:self];

Add to your input:

[self.inputSelect setInputView:_picker];

So, go implementing the delegate appropriate to your case.

Answer 2

The problem is in iOS 8. To solve

pickerView = [[UIPickerView alloc] init];

[pickerView setDataSource: self];
[pickerView setDelegate: self];

[pickerView setFrame: CGRectMake(xPoint, 50.0f, pickerWidth, 200.0f)];

pickerView.showsSelectionIndicator = YES;

[pickerView selectRow:2 inComponent:0 animated:YES];

[self.view addSubview: pickerView];
UIView *v = [[UIView alloc] initWithFrame:CGRectMake(0, 0,xPoint , pickerWidth)]; // add autorelease if you don't use ARC

v.backgroundColor = [UIColor clearColor];
[v addSubview:pickerView];
editUFCRM.inputView = pickerView;
