Done Button not working at programmatic UIBarButtonItem and UIPickerView - iphone

Question

I am creating a UIPickerView, UIToolbar, UIBarButtonItem and UIButton programmatically. I'v set the custom picker as an inputView of a textView and everything works without problem except the Done button.
Does anyone have any idea of what the problem is?
The code I've used is:
// initialize picker
CGRect cgRect =[[UIScreen mainScreen] bounds];
CGSize cgSize = cgRect.size;
_picker = [[UIPickerView alloc] init];
_picker.frame=CGRectMake(0, 0, cgSize.width, cgSize.height);
_picker.showsSelectionIndicator = YES;
_picker.delegate = self;
// toolbar of picker
UIToolbar* toolbar = [[UIToolbar alloc] init];
toolbar.frame=CGRectMake(0, 0, cgSize.width, 35);
toolbar.barStyle = UIBarStyleBlackTranslucent;
UIBarButtonItem *flexibleSpaceLeft = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
UIButton *customButton = [[UIButton alloc]initWithFrame:CGRectMake(0, 0, 60, 33)];
[customButton setTitle:#"Done" forState:UIControlStateNormal];
[customButton addTarget:self action:#selector(doneClicked:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *barCustomButton =[[UIBarButtonItem alloc] initWithCustomView:customButton];
NSMutableArray * arr = [NSMutableArray arrayWithObjects:flexibleSpaceLeft, barCustomButton, nil];
[toolbar setItems:arr animated:YES];
self.txtTeam.inputView = _picker;
[_picker addSubview:toolbar];
And the doneClicked method is;
-(void)doneClicked
{
NSLog(#"Done button clicked.");
[self.txtTeam resignFirstResponder];
}
But the Done button is not clickable.

Answer 1

UIButton *customButton = [UIButton buttonWithType:UIButtonTypeCustom];
[customButton setFrame:CGRectMake(0, 0, 30, 60)];
[customButton setTitle:#"Done" forState:UIControlStateNormal];
[customButton addTarget:self action:#selector(doneClicked:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *barCustomButton =[[UIBarButtonItem alloc] initWithCustomView:customButton];
Try Like this..

Answer 2

You have set the selector for the button to call doneClicked: but the method is called doneClicked. Remove the : from the end of the method name in the selector and it should work.

Change your code to below:-
UIButton *customButton = [UIButton buttonWithType:UIButtonTypeCustom];
customButton.frame = CGRectMake(0, 0, 60, 33);
[customButton addTarget:self action:#selector(doneClicked) forControlEvents:UIControlEventTouchUpInside];
customButton.showsTouchWhenHighlighted = YES;
[customButton setTitle:#"Done" forState:UIControlStateNormal];
customButton.imageEdgeInsets = UIEdgeInsetsMake(10, 10, 10, 10);
UIBarButtonItem *barCustomButton =[[UIBarButtonItem alloc] initWithCustomView:customButton];
just comment the below your code and modify above
// UIButton *customButton = [[UIButton alloc]initWithFrame:CGRectMake(0, 0, 60, 33)];
// [customButton setTitle:#"Done" forState:UIControlStateNormal];
//[customButton addTarget:self action:#selector(doneClicked:) forControlEvents:UIControlEventTouchUpInside];
// UIBarButtonItem *barCustomButton =[[UIBarButtonItem alloc] initWithCustomView:customButton];
