I'd try a UIScrollView

Use a UIScrollView, but set directionalLockEnabled to YES. This way, as soon as it someone starts scrolling one way, they can't scroll the other until they stop scrolling and start scrolling the other way.

it's really very simple. use a UIScrollView. it already provides scrolling in horizontal and vertical direction. and if you set the directionalLockEnabled property to YES, then the user can only scroll in one direction at a time, so no diagonally scrolling.

It's verrry simple.

Create a UIScrollView.

Add the view you want to scroll to the UIScrollView (as a subview).

Then set the content size of the scrollview.

Then set the directional lock.

Done.

Note, it's ill-advised to give you the code as then you don't learn anything. If you think you'll still learn if we give you the code, then hilight the text below.

UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:[UIScreen mainScreen].applicationFrame;

[scrollView addSubview:aViewThatYouCreated]

[scrollView setContentSize:CGSizeMake(the view you created's width, the view you created's height)];

[scrollView setDirectionalLockEnabled:YES];

[self.view addSubview:scrollView]; //or [self setView:scrollView]; depending on how your program works.
