I have a table view made of 2 arrays, a "title" and a "description". I've set numberOfRowsInSection, numberOfSectionsInTableView and titleForHeaderInSection.
I've added swipe gesture recognisers, swipe to the right and the cell accessory changes to a check mark, swipe to the left and the accessory goes back to the disclosure indicator. All working fine.
I have 2 section headers, one is Complete the other Incomplete. I'd like to have all cells under incomplete by default and when right swiping, the cell's section header is changed to complete, likewise if swiping left the cell reverts back to the incomplete header.
I've tried various things but can't seem to get my head around it. Originally I was looking to added a button but this way seems more natural.
Any advice appreciated.
Cheers.
You don't want to change the section header for that cell, you want to put that cell in the other section (complete or incomplete), no?
So you have to put the object that this cell represents in either the complete o incomplete array that feeds your tableView - and remove it from the other one respectively.

I have a collection view that is 100 points wide with a number of cells that are each also 100 points wide. I've got it setup to support scrolling and paging horizontally so the user can flick left and right and each cell occupies the entire collection view frame.
Originally, I had no scrolling and the user would tap each cell to activate something in the app. Now that its a narrow frame where only one cell can be seen at a time I feel that tapping is redundant and the cell should simply be tapped in effect when it comes in view.
Is there a way to trigger an event such as didSelectItemAtIndexPath when a given UICollectionViewCell becomes the one displayed within my collection view's frame?
UICollectionView responds to selectItemAtIndexPath:animated:scrollPosition:.
It also responds to indexPathsForVisibleItems which will be useful to determine where to make the selection.
You also need to decide when to make the selection, probably best after receiving scrollViewDidEndDecelerating: which the delegate inherits from UIScrollViewDelegate).
But it may be even better advice to look at what your code does upon selection and just do that (launched from the same place in code, probably when scrolling is finished), leaving selection out of it.
I want to add a small indicator (like a green arrow or small circle) to indicate to the user what to do next in my iPad app (apparently some of the users can't figure what to do first, even tho' I have instructions in a drop-down help file). The indicator would be visible on the left side of the row and only on the row which would be the next action to take (user should tap that row to get the next sub-view to appear).
Any ideas how to accomplish this? (I looked on SO and Google and didn't find anything that was pertinent).
Add an image view to your prototype table cell. When you want to indicate that a given row is the next thing to do, set the image of the image view for that row to your indicator image.
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 a UITableView with a navigation bar on top. I have several text fields in the cells and if i click in the cell at the bottom the keyboard hides the text field. So I googled and found this link: http://developer.apple.com/library/ios/#documentation/StringsTextFonts/Conceptual/TextAndWebiPhoneOS/KeyboardManagement/KeyboardManagement.html#//apple_ref/doc/uid/TP40009542-CH5-SW7
I used exactly that code and run my app again. Now it scrolls up (about the height of the keyboard) instead of scrolling down. Also it scrolls in every cell, even the cells at the top which will not get hided by the keyboard. Does anyone have a solution for this? I tried to log out some coordinates inside the keyWasShown: method but it's very complex for me to figure it out.
So I used trial and error and finally found out, that I have to add two superview properties behind activeField:
activeField.superview.superview.frame.origin
Do this behind every activeField in the method keyboardWasShown: and it will work. Ah and I added 70 pixels, because the view didn't scroll exactly where I wanted it to, maybe it is because of the navigation bar I use, I don't know:
activeField.superview.superview.frame.origin.y - kbSize.height + 70
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.
