static NSString *idCell = @"MyCellId";Try to reuse an already existing, but not currently used, cell created earlier with given identifier "MyCellId". If such isn't found, create a new one:
cell = (UITableViewCell *)[aTableView dequeueReusableCellWithIdentifier:idCell];
if (cell == nil)This code requires a separate stand-alone XIB, which contains nothing but your UITableViewCell. But how do you define the reuseIdenfier? That property is read-only and created when table cell is created.
static NSString *nibcell = @"MyCell";
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:nibCell owner:self options:nil];
cell = (UITableViewCell *)[nib objectAtIndex:0];
reuseIdentifierOpen your XIB in Interface Builder, select UITableViewCell object, open "Table View Cell Attributes" (press command-1) and write your hardcoded magical string "MyCellId" into "Identifier" field. Use the same string in your code as reuseIdentifier.
A string used to identify a cell that is reusable. (read-only)
@property(nonatomic, readonly, copy) NSString *reuseIdentifier
Warning: you should NEVER access objects inside XIB (NIB) by magical index into array! Apple might change "something" in next Xcode release and thus break your code. You should use IBOutlets. You have been warned.
...yes, this is one of those sad "don't do as I do, but as I tell you to" cases...
