ios - UILabel text color changes when text is changed -

UILabel is built in the interface builder. This is part of a UITableViewCell, its color is set in the red color in the Builder Builder.

I create cells here:

  - (UITableViewCell *) TableView: (UITableView *) tableView cellForRowAtIndexPath: (NSIndexPath *) index {static NSString * CellIdentifier = @ "Notation Mail"; Notification cell * cell = [Tableview deevor reusable cell with iddatifier: Cell Identified for Indeppeth: IndexPath]; // Configure cell ... cell.Notation = [self.notation object atindex: indexpath.ro]; Before UIColor * = cell.symbolLabel.textColor; Cell.symbolLabel.text = @ "New Text"; UIColor * after = cell.symbolLabel.textColor; Return cell; }   
 The first is red, as it is intended. But after changing the text UIDeviceWhiteColorSpace 0 becomes 1 after color, and the text becomes black I am using the layout myself.  
 Why does the text change its color?   
 
 
 found a solution I have created a category:  
  @implementation UILabel (KeepAttributes) - (Zero) setTextWithKeepingAttributes: (NSString *) Text {NSDictionary * attributes = [(NSAttributedString *) self.attributedText attributesAtIndex: 0 Effective Range: Zero]; Self.attributedText = [[NSAttributedString alloc] initWithString: Text attributes: attributes]; } @end   
 Then this method was used to change the text.
