TableViewCell Appearance only changes the cell's currently in the view

Question

Using UIAppearance, I am changing the Table View Cell's label colour. This works fine but it only colours the cells currently being seen. All the cell's out of the view (not being seen) are still the default colour (black).

In a summary, the method only changes the cell's currently being seen, not the cells out of view (scrolled out of view).

Here is my UIAppearance Code:

[[UILabel appearanceWhenContainedIn:[_textLabel class], nil]
 setTextColor:[UIColor colorWithRed:(204.0f/255.0f) green:(204.0f/255.0f) blue:(204.0f/255.0f) alpha:1.0f]];

Can you post more code please? Like the part where you call these method for example. — jbouaziz, Mar 18 '14 at 04:21

I guess you have a typo here, _textLabel must be a UITableViewCell not a UILabel,

[[UILabel appearanceWhenContainedIn:[YourTableViewCell class], nil]
 setTextColor:[UIColor colorWithRed:(204.0f/255.0f) green:(204.0f/255.0f) blue:(204.0f/255.0f) alpha:1.0f]];

You may check reusing cell in your cellForRowAtIndexPath:

static NSString *CellIdentifier = @"SimpleTableItem";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell==nil){
   cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}

Nope, it's a UILabel because the title of the cell is the problem, not the cell background colour. – Colton Anglin Mar 18 '14 at 04:18
It wouldn't matter anyway as _textLabel is part of UITableViewCell – Colton Anglin Mar 18 '14 at 04:19
That's the same thing as I am doing but just calling the UITableViewCell directly – Colton Anglin Mar 18 '14 at 04:22
That's not the problem. The problem is that The code I'm calling only changes the text color of the cells currently in the viewable area. – Colton Anglin Mar 18 '14 at 04:24
hmm, can you post your `cellForRowAtIndexPath`. – Tarek Hallak Mar 18 '14 at 04:27
Do you have any reason for not reusing the cells? – Tarek Hallak Mar 18 '14 at 04:34
Nope and Could that be the problem? – Colton Anglin Mar 18 '14 at 04:36
I think so, anyway you have to optimize your cell reusing, it is very important performance-wise also, it is two lines of code dude. One more thing please remove this `[tableView deselectRowAtIndexPath:indexPath animated:YES];` – Tarek Hallak Mar 18 '14 at 04:39
Hmm, Im still a beginner at this. Mind posting that reuse code? – Colton Anglin Mar 18 '14 at 04:44
