I have a problem with all my tableview and its separator's cell. Randomly one separator cell (sometimes more than one) is higher than the others and I don´t know why. I tried with setSeparatorColor and also adding a custom view at the end of every cell but is always the same effect. Besides, when I scrolling the tableview this occurs in other cells.

I searched a lot about this, couldn't find an answer and I am stuck with this problem for some days already.
I have a UITableView with 3 sections, each one with custom cells (xib). The first section must grow accordingly with one of its labels.
The second one is static, it shows up just an static image and basic height.
The third one is like a comment cell, with UIImageView, labels etc. One of this labels must grow till a limit height.
I managed to show the 3 custom cells, but the first and the second one (which are not static height), show only partially. If I set manually the Height of the row I can see it entirely, but all section cells grow and it is not what I need.
The constraints to auto layout, I keep getting some conflicts but could not find any solution, tried to debug the view stack, no success.
Custom Cell
Constraints of custom cell
Can anyone help me or point me to a direction?
Thanks in advance!
I had the same problem. I solved it like this. Set tableView estimatedRowHeight to minimum row height. Set tableView rowHeight to UITableViewAutomaticDimension.
1) For dynamic cell height - Give the label leading, trailing, top, bottom and height greater than equals to minimum height.
2) For fixed cell height - Give the label leading, trailing, top, bottom and height equals to fixed height whatever you wanted.
By this your dynamic height cells will grow and fixed ones will be fixed. If you did not get what i said then post a sample project with just this custom implementation on git or somewhere else. I will correct it.
Thank you.
I am not very experienced with UICollectionView and Auto-Layout.
I have a very basic UICollectionView inside a root view. The root view seems to have a Navigation Item.
I created a custom cell which is really a square in proper size to allow 2 such cells per row using the FlowLayout.
There are 8 such cells in the view - it is basically a grid. I have absolutely no constraints on the view.
The collection view occupies the entire size of the root view according to the IB and in the editor, the first cell is placed right under the navigation item which is perfect.
However, when I ran the app in the simulator and scrolled the collectionview all the way to the button, I see only a partial fragment of both cells in the last row. I can see I have scrolled all the way down...
Obviously there seems to be some sort of overflow...but I would have thought uicollectionview would automatically handle the overflow and make all the cells visible?
When I set number of items in IB I can see that the cells in the last row are only partially visible.
Seems like content size of the collection view is not right - that's my guess..
What do I need to do to adjust things in IB so that all of my cells are visible...I do not want to hardcode any values in the code...
Thanks.
Solved. It turns out simulator does not show the entire collection view...the same shows fine on the device... What a headache...
I have UITableView with custom looking cells. Now user can scroll past the bottom and see that there are no more rows (cells) and see background. I want to create impression that there are more rows below, but they should not be added to tableview, so when user scrolls down, it bounces back to last useful cell.
TableFooter and subview expands content and user can scroll there (or maybe I was doing it wrong).
Right now I added new empty cells and after any action that may recount contentSize I specifically set contentSize to default setting. But I feel like it's not the right way (although it works). Is there some other way?
I tried searching, but it's hard to explain what I want in few sentences, not to mention in search line.
Well, I have a uitableview with 4 cells with content, so there are 4 cells displayed and other 4 cells displayed without content to fit the screen. I want all the cells in my uitableview to have a background image (the same for all). When I change the background of the cell on cellForRowAtIndexPath method only the 4 cells with content get the background image and the other 4 without content are still white. Is there any way I can set the background to all the cells an not only to the cells with content?
You may be able to add the additional four cells as blank cells to your table view. This way, they still look exactly like one of your other cells. An alternative may be to make the cells larger which would make you need to use less "filler" cells.
Hope this helps!
increase the number of rows in the section....
lets say u want 100 cells to get the background image... then the cellforRowAtIndex path will be called for 100 cells and hence will set the background..
Hope it works
Let me Know
I have tableView with a lot of cells. I need to remove cells, which user passes while scrolling the tableView.
cellForRowAtIndexPath is called when user scroll to this cell to perform its content and the question is there similar method to know what cells are out of the screen while scrolling?
Take a look at UITableView's visibleCells method. It'll tell which ones are visible. Then I'm assuming you know how many total cells there are and you can do the logic to work out which ones are not visible.
