UIButton does not respond with UIScrollview Paging - ios

Question

I am running into a problem with the uiscrollview. When I have it as a regular scroll view all the UIButtons work as expected. When I add paging to it the buttons no longer respond. I have a top edge sticking out and they do accept the press from there. They are definitely behind the scroll view but they will scroll on and off the page when it is moved like I want them to. I have read a lot of different responses but most will not provide the answer unless you use gesture controllers. I am attaching the piece of code that creates the paging. can you let me know what I might be missing?
-(void)scollPagingSetup:(float)frameSize {
float numberOfPages;
int maxheight;
[self.view setPagingEnabled:YES];
[self.view setBounces:YES];
UIView *first = [[UIView alloc]initWithFrame:self.view.frame];
[self.view addSubview:first];
maxheight = [UIScreen mainScreen].bounds.size.height;
numberOfPages = ceil(frameSize/maxheight);
for (int i = 1; i < numberOfPages; i++) {
CGRect frame;
frame.origin.x = 0;
frame.origin.y = self.view.frame.size.height * i;
frame.size = self.view.frame.size;
UIView *subview = [[UIView alloc] initWithFrame:frame];
[self.view addSubview:subview];
}
self.view.contentSize = CGSizeMake(self.view.frame.size.width, self.view.frame.size.height *numberOfPages);
}
Thank you in advance for taking a look. I found something that would answer this problem but I was unable to grasp what the real solutions was to the problem. here is the link to that question:

Answer 1

The problem is that the content size is not set properly so the "clickable area" (content area's size) is also not set... on your last line of code (line before the last "}") you are setting the scrollView's contentSize's frame to itself which will just be 0... try this instead (I use "first" (the nested view) instead of "self" (the scroll-view itself).
self.view.contentSize = CGSizeMake(firstframe.origin.x, (firstframe.origin.y - 20) * numberOfPages);
Note from question-poster on edited answer:
I made a change to the answer. After I worked with the app some more i was not scrolling fully. I made the change to reflect what I did to fix this and cause a full page scroll. the -20 offset was needed due to the offset of the uiscrollview. This offset can be seen in interface builder.
