I have a table view, amongst the table, in each row i want to display an image to the extreme left, some string in the middle, a number after that and again a string followed by a number, n all that should be in different font styles and sizes. Now i did this using custom-cells, but that is just for one row, what if user wants to enter data and then view the added info in the next row of the table. How do i add multiple custom cells to my view?
Update the datasource of your tableView and call reloadData method
[tableView reloadData];

I have a tableView with custom table cells which displays a list of sayings. While selecting a cell (say "saying1") from the tableView, the cell will get selected and will moves to next view controller for showing an explanation of selected saying. In that view controller two buttons "Previous" and "Next" are there for navigating to previous and next saying. So user may select next button for seeing next saying (say "saying2"). But the problem here is, In this stage when i navigate back to my tableview, the cell selected will be "saying1" not "saying2".
In order to solve this problem, i collected the currently selected sayings ("saying2's") index from array (ie,index will be 1) and passed it to the previous tableView through segue and converted that value into NSIndexpath. After this step i don't know what to do. Please help me in solving this.
You can specifically select a cell by calling following method present in UITableView class :
selectRowAtIndexPath:animated:scrollPosition:
refere to following link : https://developer.apple.com/library/ios/documentation/uikit/reference/UITableView_Class/Reference/Reference.html#//apple_ref/occ/instm/UITableView/selectRowAtIndexPath:animated:scrollPosition:
I have a UITableView. It pulls information from the address book where needed. I also have the bottom cell programatically made to be a button that loads up the address book.
My problem is when I allow the user to delete a row by swiping right, it shows it for the last cell I have made as a button. Is there a way to not allow a delete function showing on just 1 cell?
Implement tableView:canEditRowAtIndexPath: in the table view's dataSource and return NO for the row you don't want to be deletable.
You have to implement [UITableViewDelegate tableView:editingStyleForRowAtIndexPath:] and return UITableViewCellEditingStyleDelete only for the cells that can be deleted. Return UITableViewCellEditingStyleNone for the cells that can't be deleted.
I'm trying to programmatically select cells in a UICollection view. I'm new to Obj-C and I'm not quite sure how to use the selectItemAtIndexPath property. I can grab an array of the images the user has previously selected. It is just an array of numbers corresponding to named images. But I'm not sure how to use that information with selectItemAtIndexPath.
I've looked for examples of someone using
- (void)selectItemAtIndexPath:(NSIndexPath *)indexPath animated:(BOOL)animated scrollPosition:(UICollectionViewScrollPosition)scrollPosition
But I'm not sure how to use it with my UICollectionView so I can have the right cells selected when the view loads and thus be highlighted. I have multiple selection on.
You should call selectItemAtIndexPath: for each cell you want to highlight, like so:
[self.collectionView selectItemAtIndexPath:path animated:NO scrollPosition:UICollectionViewScrollPositionNone]
Note that for one item (and one only!) you probably want to set the animated property to YES and provide a scroll position (one item only because otherwise you're going to be making a lot of needless animation calls).
You'll first need to get the index paths of the cells you want to select. The index path consists of two numbers: the section the cell is in and the row number (or order, if your collection view doesn't have rows) of the cell inside that section.
If you store the index paths of the cells the user has selected in an array then you can just iterate through. Otherwise you'll need to find the index path out, using a UICollectionView method such as indexPathForCell.
My table view covers part of the view. If I have 20 objects, I am displaying all of them in a tableview. But I want to know that how many cell are loaded that are visible to the user.
(i.e. first 5 cells data is visible for me: when I scroll down, the remaining cells will load. Here I want to know without scrolling how many cell are loaded.)
Is this possible?
You can use [tableView visibleCells] count], which returns numbers of the table cells that are visible, if I understand correctly what you want.
The below code will give you the array of indexpath of cells currently visible
NSArray *visiblePaths = [self.tableView indexPathsForVisibleRows];
after getting the index path you can easily access the cell at a particular indexpath
Its usually : (tableView's height / cell row height ) + 1
Can you take the size of the visible part of the table, and then the size of one cell, and divide them to know how many of them fit in the screen?
Is there a way to move the highlighted tableviewcell programatically. If I wanted to highlight cell number 3 and then highlight cell number 4 instead, based on something the user did in the detail view of my split view controller, can I do this?
Is there a way I can get the indexpath for the row two below one that I have?
Thanks!
You can do this via the UITableView selectRowAtIndexPath:animated:scrollPosition: method.
In terms of getting the "next" row from the indexPath, you can simply use the indexPath.row property (as supplied from your UITableViewDelegate's tableView:didDeselectRowAtIndexPath: method) as the basis for the selected row.
