UIScrollView with UIButton(s) App crash

[amilmac]

Hi friends,

In a View Based App, i´ve implemented in one view a scroll (UIScrollView) in part of view and i have added buttons, but for any reason, when i build project and go to the view with the scroll and buttons, app crash or freeze, here is the part of code where i implement the scroll and the buttons:

- (void)viewDidLoad

{

    [super viewDidLoad];

    // Do any additional setup after loading the view from its nib.

     UIImageView *tempImageView=[[UIImageView alloc]

     initWithImage:[UIImage imageNamed:@"back.png"]];

     self.imageView = tempImageView;

     

     //scrollView.contentSize = CGSizeMake(imageView.frame.size.width, imageView.frame.size.height);

        scrollView.contentSize = CGSizeMake(320,600);

     scrollView.maximumZoomScale = 4.0;

     scrollView.minimumZoomScale = 0.75;

     scrollView.clipsToBounds = YES;

     scrollView.delegate = self;

     
     [scrollView addSubview:imageView];

     
     [tempImageView release];

     

    //UIButton *homeButton = [[UIButton alloc] initWithFrame:CGRectMake(155.0, 217.0, 72.0, 67.0)];  

    UIButton *homeButton = [[UIButton alloc] initWithFrame:CGRectMake(10, 10, 84, 84)]; 

    [homeButton setTitle:@"" forState:UIControlStateNormal];     

    [homeButton setImage:[UIImage imageNamed:@"imagebutton1.png"] forState:UIControlStateNormal];     

    [homeButton addTarget:self action:@selector(toggleView) forControlEvents:UIControlEventTouchUpInside];

    [scrollView addSubview:homeButton];


    [homeButton release]; 

    UIButton *homeButton2 = [[UIButton alloc] initWithFrame:CGRectMake(100, 10, 84, 84)]; 

    [homeButton2 setTitle:@"" forState:UIControlStateNormal];     

    [homeButton2 setImage:[UIImage imageNamed:@"imagebutton2.png"] forState:UIControlStateNormal];     

    [homeButton2 addTarget:self action:@selector(toggleView) forControlEvents:UIControlEventTouchUpInside];

    [scrollView addSubview:homeButton2];



    [homeButton2 release]; 



// Follow adding rest UIButtons (about 20)    


}

Thanks in advance for all help and suggestions!! All help will be hight appreciated!

Hi dany,

What do you refer with toggleView? Maybe IBAction on button to load the View that contains the scroll?

Debug show a :

int retVal = UIApplicationMain(argc, argv, nil, nil); // Thread 1: Program received signal "EXC_BAD_ACCESS"

And happen when i atempt to click or move the scrollView.

Thank you!

    [homeButton2 addTarget:self action:@selector(toggleView) forControlEvents:UIControlEventTouchUpInside];

you should have a selector called in this mode....

Yes Dany, as you can see in the code i´ve posted i am adding code like you write (with the toggleView)

[amilmac]

Could you please write a little code as example for give me more light with code you refer?

Thank you!

[dany_dev]

i mean that in your code you have something like

-(void)toggleView{

}

post the code, maybe the problem is here.
