When using TTTableTextItem(or some other classes which are the subclasses of TTTableTextItem) in TTTableViewController, there will exist a bug. With Simulator or device basing on iOS4.3 is ok, problem happens in iOS5.

in iOS 5: http://media.tumblr.com/tumblr_lz69brENGk1r6gbbu.png

yep you can see the white background of the text in such cells.

According to the source code i found something in TTTableTextItemCell.m:

- (void)setObject:(id)object {

    if (_item != object) {

    [super setObject:object];

    TTTableTextItem* item = object;

    self.textLabel.text = item.text;

    self.textLabel.backgroundColor = TTSTYLEVAR(backgroundTextColor);//here it is

    //some codes here………..

}

And then in the definition of TTSTYLEVAR i found:

#define TTSTYLEVAR(_VARNAME) [TTSTYLESHEET _VARNAME]

and in TTDefaultStyleSheet.m:

- (UIColor*)backgroundTextColor {

    return [UIColor whiteColor];

}

so, it's clear that the function backgroundTextColor caught the problem. And the color changing is coded in the function

- (void)setObject:(id)object;

but not in

- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString*)identifier, so it will be just fine in iOS4.

I'm just a newbie of three20, so i'll apologize if there is anything wrong of my words.

I also post this bug in my blog, but, in Chinese.

Happy to learn and discuss.
