UIBUTTON and picker view

Question

I want to display a picker when the user clicks on a button I subclassed the UIButton and changed its inputview so that it is writable.

I followed this link http://

Answer 1

1) Create a subclass of a UIButton

.h

#import 

@interface UIButtonAsFirstResponder : UIButton

@property (strong, nonatomic) UIView *inputView;
@property (strong, nonatomic) UIView *inputAccessoryView;

@end

.m

#import "UIButtonAsFirstResponder.h"

@implementation UIButtonAsFirstResponder

- (BOOL) canBecomeFirstResponder
{
    return YES;
}

@end

2) Set inputView (if needed also inputAccessoryView) in your view controller (to your picker or any other custom view)

3) Create IBAction for your button in your view controller

- (IBAction)becom:(id)sender {
    [sender becomeFirstResponder];
}

If you want to remove keyboard, call on your button:

[button resignFirstResponder];

or in view controller:

[self.view endEditing:YES];
