UITableView didSelect delegate doesnt gets called?

Question

In my app, I have added an UITableView over a ScrollView. I have disabled scrolling in table view. So, only the scrollView Scrolls, I have adjusted the scroll view content Size with the tableView Frame. So, I can access all the cells.

Consider, there are 5 rows visible in the screen, if I tap any of the row, the didSelectRowAtIndexPath method gets called. If I scroll down, say to 6th cell and tap on it. The method doesnt gets called.

Same issues happens with UIcollectionView.

The reason why I have added so is. When I scroll the Scroll View, a view in that should get fixed in the top and the tableView behind it should go on scrolling. You might have seen in many of the apps in Android. So, I have used the ScrollView didScroll delegate to get the offset position. As per it, I will make the view to be fixed and vice versa.

For my design, I need to do so. I have customized some functions like in android. — Balachandar Mutharasu, Jul 06 '16 at 11:10

check that clips to bounds property is true for view and scrollview and also apply background colour and see the borders — Prashant Tukadiya, Jul 06 '16 at 11:27
@MikeAlter, If I do so, The tableView content which appears below the screen, disappears. How can I clear it. — Balachandar Mutharasu, Jul 06 '16 at 11:36
your content is disappears because it is clips to superview , in simple words your view size is small that's why it disappears, you can check same by apply different colours and check frame ... — Prashant Tukadiya, Jul 06 '16 at 11:52
I cleared the issuw. While changing the values in the table dynamically, I tried to chnage the height of the Table, now, I created a constant for height contraint and changed it . It worked. Thanks guys. Especially @MikeAlter — Balachandar Mutharasu, Jul 06 '16 at 12:40
Just another thought: did you know, that a UITableView is a UIScrollView subclass? So if you create a UITableView and set the delegate, it will also call the scrollViewDidScroll method, with the tableView as a parameter, and it will have contentSize and contentOffset. So maybe you can just get rid of the scrollView itself, to keeps things simpler. — romeouald, Jul 06 '16 at 12:43
YA @romeouald, I have set Tag for each Views and used conditions in appropriate places. — Balachandar Mutharasu, Jul 06 '16 at 14:17

Make the height of UITableView same as the content height of table. Then set the content size of UIScrollView as the height of UITableView

Here is a brief example to demonstrate

CGRect rect = tblTopics.frame;
rect.size.height = tblTopics.contentSize.height;
tblTopics.frame = rect;

self.scrlVwFacultyDtl.contentSize = CGSizeMake(self.scrlVwFacultyDtl.frame.size.width, tblTopics.frame.size.height);

In the above example the tblTopics is the instance of UITableView and scrlVwFacultyDtl is the instance of UIScrollView

hope it will help you..

Thanks bro, I got it. With the help of the comments. I just changes the height constraints dynamically. — Balachandar Mutharasu, Jul 06 '16 at 14:18
