UITableview cell Overlap on each with arm64

Question

hi i am trying to upgrade my app to support iOS arm64 after adding arm64 Tableview cells Overlap on each (on iPhone 5s , 6 ,6+)

with arm64

Answer 1

The problem is due to precision from 32bit to 64bit.
Use Apple provided typedef primitive type, make all int to be NSInteger and float to CGFloat.

Pay attention that if you perform some calculation that should return a float number is really returning a float, if you divide 2 ints they will return an int not a float. In general if operands are of different types, the compiler will promote all to the largest or most precise type.

Answer 2

There are several possibilities. If you are reusing label or image then set it Nil before setting value for next row.

 rosterCell.imgContact.image = Nil; // rosterCell is custom tableview cell object
 rosterCell.lblContact.text = @"";

Another reason may be that you haven't set Autolayout constraint. It may help you

Answer 3

You should change float to CGFloat for this method's output:

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
// Now typing
if (indexPath.section >= [self.bubbleSection count])
{
    return MAX([UIBubbleTypingTableViewCell height], self.showAvatars ? 52 : 0);
}

// Header
if (indexPath.row == 0)
{
    return [UIBubbleHeaderTableViewCell height];
}

NSBubbleData *data = [[self.bubbleSection objectAtIndex:indexPath.section] objectAtIndex:indexPath.row - 1];

return (CGFloat)MAX(data.insets.top + data.view.frame.size.height + data.insets.bottom, self.showAvatars ? 52 : 0);
}
