Incompatible pointer type initializing 'CustomCellView *' with an expression of type UItableViewCell

问题:

Can you help me understandand/fix the error below. I don't understand as CustomCellView is a subclass of UItableViewCell. The code gets compiled but the warning is still there:

Incompatible pointer type initializing 'CustomCellView *' with an expression of type `UItableViewCell` 

I got the 2nd line below hightlighted:

static NSString *CellIdentifier = @"CustomCell"; CustomCellView *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 

回答1:

static NSString *CellIdentifier = @"CustomCell"; CustomCellView *cell =(CustomCellView*) [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 

you need to type cast to your cell

回答2:

static NSString *CellIdentifier = @"CustomCell"; CustomCellView *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath]; 

回答3:

For custom cell below code is also working fine with given frame..

  CustomCell *cell= [[[CustomCell alloc] initWithFrame:CGRectZero reuseIdentifier:nil] autorelease];
