Programmatically created button not firing event in custom view in iOS - iphone

Question

On iOS, I created a button programmatically but the event is not firing.
UIButton * anyButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[anyButton addTarget:self action:#selector(handleAnyButton:) forControlEvents:UIControlEventTouchUpInside];
anyButton.frame = CGRectMake(150, 350, 22, 22);
[self addSubview:anyButton];
The code is placed inside a custom view (not custom view controller), but I cannot make it fire the event. The press animation is not showing. The custom view has userInteractionEnabled enabled. I also tried using storyboard to create another button on the same view and that one is working. The button code is done in initWithFrame. Must be some simple error I haven't caught and I have been pounding my head over this one for hours.
EDIT:
The event handler:
-(void) handleAnyButton:(UIButton *)button
{
NSLog(#"handleAnybutton called");
}
EDIT2:
The above button codes is done within a [self setup] of class PKLocationsSelectionView.
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
// Initialization code
[self setup];
}
return self;
}
And this view was created programmatically within the view controller (PKLocSelectionViewController) responsible for this hierarchy:
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
CGFloat fieldsHeight = 88;
UIView * view = [[PKLocationsSelectionView alloc] initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, fieldsHeight)];
[self.view addSubview:view];
}

Answer 1

It looks like your button frame
anyButton.frame = CGRectMake(150, 350, 22, 22);
is outside of parent bounds
CGFloat fieldsHeight = 88;
UIView * view = [[PKLocationsSelectionView alloc] initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, fieldsHeight)];

Here is the code that works for me:
MyCustomView.m:
#import "MyCustomView.h"
#implementation MyCustomView
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
// Initialization code
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(0, 0, 100, 100);
[button addTarget:self action:#selector(greet:) forControlEvents:UIControlEventTouchUpInside];
[button setTitle:#"Greet" forState:UIControlStateNormal];
[self addSubview:button];
self.backgroundColor = [UIColor greenColor];
}
return self;
}
-(void) greet:(id) sender
{
NSLog(#"greet!");
}
And here is the ViewController.m:
- (void)viewDidLoad
{
[super viewDidLoad];
MyCustomView *view = [[MyCustomView alloc] init];
view.frame = CGRectMake(0, 0, 100, 100);
[self.view addSubview:view];
}

EDIT2: Could it be the Button is not fully enclosed within the coordinates of the container (PKLocationsSelectionView) view?
The height of the PKLocationsSelectionView is 88 from your code and the position of the button seems to be outside this. I think if the button is not enclosed within the frame of the superview then it won't receive touches.

Try and change your View initialization code in viewDidLoad, to give a static frame and see if it works..
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
CGFloat fieldsHeight = 88;
//See the change in below line.. instead of using self.view.bounds.size.width
// I used a static width.. 320 pixel for the moment..
UIView * view = [[PKLocationsSelectionView alloc] initWithFrame:CGRectMake(0, 0, 320.0, fieldsHeight)];
[self.view addSubview:view];
}
In viewDidLoad view hierarchy of controller will not be drawn completely..So self.view.bounds.size.width may be giving incorrect values.. To access self.view.frame and self.view.bounds, you should atleast wait until viewWillAppear gets called.
Also, your button origin.y is at 350 which in a view which has maximum height of only 88.. Any control outside parent's frame won't receive touches..
