How can I get a uitableViewCell by indexPath?
How can I get a UITableViewCell by indexPath? Like this:
I use the UIActionSheet, when I click confirm UIButton I want to change the cell text.
The nowIndex I define as a property
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (buttonIndex == 0)
{
NSInteger section = [nowIndex section];
NSInteger row = [nowIndex row];
NSDateFormatter *formatter = [[[NSDateFormatter alloc] init] autorelease];
formatter.dateFormat = @"yyyy-MM-dd";
if (section == 0)
{
if (row == 0)
{
}
else if (row == 1)
{
UILabel *content = (UILabel *)[[(UITableView *)[actionSheet ] cellForRowAtIndexPath:nowIndex] viewWithTag:contentTag];
content.text = [formatter stringFromDate:checkInDate.date];
}
else if (row == 2)
{
}
}
}
}
[(UITableViewCell *)[(UITableView *)self cellForRowAtIndexPath:nowIndex]
will give you uitableviewcell. But I am not sure what exactly you are asking for! Because you have this code and still you asking how to get uitableviewcell. Some more information will help to answer you :)
ADD: Here is an alternate syntax that achieves the same thing without the cast.
UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:nowIndex];
Finally, I get the cell using the following code:
UITableViewCell *cell = (UITableViewCell *)[(UITableView *)self.view cellForRowAtIndexPath:nowIndex];
Because the class is extended UITableViewController:
@interface SearchHotelViewController : UITableViewController
So, the self is "SearchHotelViewController".
Here is a code to get custom cell from index path
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:2 inSection:0];
YourCell *cell = (YourCell *)[tblRegister cellForRowAtIndexPath:indexPath];
For Swift
let indexpath = NSIndexPath(forRow: 2, inSection: 0)
let currentCell = tblTest.cellForRowAtIndexPath(indexpath) as! CellTest
For Swift 4 (for collectionview)
let indexpath = NSIndexPath(row: 2, section: 0)
let cell = self.colVw!.cellForItem(at: indexpath as IndexPath) as? ColViewCell
For Swift 4
let indexPath = IndexPath(row: 0, section: 0)
let cell = tableView.cellForRow(at: indexPath)
You can use the following code to get last cell.
UITableViewCell *cell = [tableView cellForRowAtIndexPath:lastIndexPath];
I'm not quite sure what your problem is, but you need to specify the parameter name like so.
-(void) changeCellText:(NSIndexPath *) nowIndex{
UILabel *content = (UILabel *)[[(UITableViewCell *)[(UITableView *)self cellForRowAtIndexPath:nowIndex] contentView] viewWithTag:contentTag];
content.text = [formatter stringFromDate:checkInDate.date];
}
Swift 3
let indexpath = NSIndexPath(row: 0, section: 0)
let currentCell = tableView.cellForRow(at: indexpath as IndexPath)!
Swift
let indexpath = IndexPath(row: 0, section: 0)
if let cell = tableView.cellForRow(at: indexPath) as? <UITableViewCell or CustomCell> {
cell.backgroundColor = UIColor.red
}

dataSourceproperty of your tableView is set to, but usually that isself.
