Question

Ok I am trying to replace the Keyboard with the UIpicker. I got the code in, the Uipicker always show, and when you click on the text field of course the keyboard comes up….I even put break points in to see if it makes it to the code that tells it to hide the keyboard and it never does….Would someone look at it and see where i went wrong

 #import "collectionViewViewController.h"
#import "activityCell.h"

@interface collectionViewViewController ()

    NSArray *imageArray;
    NSArray *labelArray;

You’re not overriding the right delegate method:

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField {
    <code that presentes the picker view>
    return NO;
}

That should stop the text field from showing the keyboard, and instead do whatever you want.
