Adding a UIButton to UIScrollView

Question:

I am trying to add the UIButton to UIScrollView.

I have added the UIImageView with background image *(size: 320 * 620)*. Then I added this UIImageView to UIScrollView, and It works fine.

But now I want to add UIButton at position at : <em>(60, 500);</em> (below screen that would appear after scrolling).

I have tried following code, but the button is added on UIView not on scrollview. Button is not getting displayed on the top.

Code :

- (void)viewDidLoad { [super viewDidLoad]; self.navigationController.navigationBar.hidden = TRUE; UIImageView *tempImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"SingleModelVar.png"]]; self.imageView = tempImageView; [tempImageView release]; imageView.userInteractionEnabled = YES; scrollView=[[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 320, 460)]; //fit to screen //scrollView.delaysContentTouches = NO; scrollView.contentSize = CGSizeMake(320, imageView.frame.size.height); //imageView.frame.size.height=620 here scrollView.maximumZoomScale = 4.0; scrollView.minimumZoomScale = 0.75; scrollView.clipsToBounds = YES; scrollView.delegate = self; //The Problem begins .......... btnStartDate=[[UIButton alloc] initWithFrame:CGRectMake(60,500,100,20)]; [scrollView addSubview:btnStartDate]; //[self.view addSubview:btnStartDate]; btnEndDate=[[UIButton alloc] initWithFrame:CGRectMake(60,530,100,20)]; [scrollView addSubview:btnEndDate]; //[self.view addSubview:btnEndDate]; [scrollView addSubview:imageView]; [[self view] addSubview:scrollView]; }

Answer1:

it is not displayed at the top because you added them before you added the imageView. Put [scrollView addSubview:imageView]; before btnStartDate=[[UIButton alloc] initWithFrame:CGRectMake(60,500,100,20)];
