I add a custom view to my UIScrollView
How can I make my UIScrollView, respond to scroll events
Also, there are a few buttons in my customView with should respond on “touch up inside”
entry526 = [[_526 alloc] initWithNibName:@"0526" bundle:nil];
entry526.view.frame = entry526.view.bounds;
[self.scrollView addSubview:entry526.view];
self.scrollView.contentSize = entry526.view.frame.size;
entry526 = nil;
UPD:
I have managed to make my ScrollView scroll, but buttons still do not respond. This is how they are presented:
UIScrollView
-UIView
-UIButton

To make your scroll view respond to scroll events, you need to set the contentSize property to something larger than the frame of the UIScrollView.
To make your buttons respond to touch up inside, do it like you always would. Link them to an IBAction in Interface Builder or call the addTarget on the button in code.
There are a million examples of both these questions on SO and the web.
