iOS Subview with buttons not responding to touches. - ios

Question

I have a UIView Subclass that has a frame/image with buttons in it. I'm trying to add it to my view controller however when I do it shows up but none of the buttons will register ANY touches.
Here is my UIView Subclass.
#import "ControlView.h"
#implementation ControlView
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
CGRect slideFrame = CGRectMake(0, 402, 320, 82);
slider = [[UIView alloc] initWithFrame:slideFrame];
slider.backgroundColor = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:#"shelf.png"]];
[self addSubview:slider];
UIImage *btnImage = [UIImage imageNamed:#"NavBar_01.png"];
UIImage *btnImageSelected = [UIImage imageNamed:#"NavBar_01_s.png"];
btnImage = [UIImage imageNamed:#"NavBar_01.png"];
btnImageSelected = [UIImage imageNamed:#"NavBar_01_s.png"];
btn1 = [UIButton buttonWithType:UIButtonTypeCustom];
btn1.frame = CGRectMake(12, 28, 70, 50);
[btn1 setBackgroundImage:btnImage forState:UIControlStateNormal];
[btn1 setBackgroundImage:btnImageSelected forState:UIControlStateSelected];
[slider addSubview:btn1];
[slider bringSubviewToFront:btn1];
[btn1 addTarget:self action:#selector(home) forControlEvents:UIControlEventTouchUpInside];
btnImage = [UIImage imageNamed:#"NavBar_02.png"];
btnImageSelected = [UIImage imageNamed:#"NavBar_02_s.png"];
btn2 = [UIButton buttonWithType:UIButtonTypeCustom];
btn2.frame = CGRectMake(87, 28, 70, 50);
[btn2 setBackgroundImage:btnImage forState:UIControlStateNormal];
[btn2 setBackgroundImage:btnImageSelected forState:UIControlStateSelected];
[slider addSubview:btn2];
[slider bringSubviewToFront:btn2];
// [btn2 addTarget:self action:#selector() forControlEvents:UIControlEventTouchUpInside];
btnImage = [UIImage imageNamed:#"NavBar_03.png"];
btnImageSelected = [UIImage imageNamed:#"NavBar_03_s.png"];
btn3 = [UIButton buttonWithType:UIButtonTypeCustom];
btn3.frame = CGRectMake(162, 28, 70, 50);
[btn3 setBackgroundImage:btnImage forState:UIControlStateNormal];
[btn3 setBackgroundImage:btnImageSelected forState:UIControlStateSelected];
[slider addSubview:btn3];
[slider bringSubviewToFront:btn3];
// [btn3 addTarget:self action:#selector() forControlEvents:UIControlEventTouchUpInside];
btnImage = [UIImage imageNamed:#"NavBar_04.png"];
btnImageSelected = [UIImage imageNamed:#"NavBar_04_s.png"];
btn4 = [UIButton buttonWithType:UIButtonTypeCustom];
btn4.frame = CGRectMake(237, 28, 70, 50);
[btn4 setBackgroundImage:btnImage forState:UIControlStateNormal];
[btn4 setBackgroundImage:btnImageSelected forState:UIControlStateSelected];
[slider addSubview:btn4];
[slider bringSubviewToFront:btn4];
// [btn4 addTarget:self action:#selector() forControlEvents:UIControlEventTouchUpInside];
UISwipeGestureRecognizer *recognizer;
recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:#selector(slideUp)];
[recognizer setDirection:(UISwipeGestureRecognizerDirectionUp)];
[self addGestureRecognizer:recognizer];
recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:#selector(slideDown)];
[recognizer setDirection:(UISwipeGestureRecognizerDirectionDown)];
[self addGestureRecognizer:recognizer];
}
return self;
}
-(void)slideUp
{
// Slide up based on y axis
CGRect frame = slider.frame;
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:.75];
frame.origin.y = 320;
slider.frame = frame;
[UIView commitAnimations];
}
-(void)slideDown
{
CGRect frame = slider.frame;
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:.75];
frame.origin.y = 425;
slider.frame = frame;
[UIView commitAnimations];
}
/*
// Only override drawRect: if you perform custom drawing.
// An empty implementation adversely affects performance during animation.
- (void)drawRect:(CGRect)rect
{
// Drawing code
}
*/
#end
And this is how I'm adding it to my ViewController.
ControlView *cont = [[ControlView alloc]init];
[homeView.view addSubview:cont];
I tried adding the same code to a ViewController and the buttons etc.. worked so I'm sure this is something simple/stupid with Delegates/Self etc.. between the subview and the ViewController however I have a mental block.

Answer 1

You are doing this?
ControlView *cont = [[ControlView alloc]init];
you are supposed to do
ControlView *cont = [[ControlView alloc]initWithFrame:self.view.frame];
