Can not change UILabel text color

I want to change the UILabel text color but I can't change the color, This is how my code looks like.

UILabel *categoryTitle = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 46, 16)];
categoryTitle.text = @"abc";
categoryTitle.backgroundColor = [UIColor clearColor];
categoryTitle.font = [UIFont systemFontOfSize:12];
categoryTitle.textAlignment = UITextAlignmentCenter;
categoryTitle.adjustsFontSizeToFitWidth = YES;
categoryTitle.textColor = [UIColor colorWithRed:188 green:149 blue:88 alpha:1.0];
[self.view addSubview:categoryTitle];
[categoryTitle release];

The label text color is white ,not my custom color.

Thank for any help.

// This is wrong 
categoryTitle.textColor = [UIColor colorWithRed:188 green:149 blue:88 alpha:1.0];

// This should be  
categoryTitle.textColor = [UIColor colorWithRed:188/255 green:149/255 blue:88/255 alpha:1.0];

// In the documentation, the limit of the parameters are mentioned.

Add attributed text color in swift code.

Swift 4:

  let greenColor = UIColor(red: 10/255, green: 190/255, blue: 50/255, alpha: 1)
  let attributedStringColor = [NSAttributedStringKey.foregroundColor : greenColor];

  let attributedString = NSAttributedString(string: "Hello World!", attributes: attributedStringColor)
  label.attributedText = attributedString

for Swift 3:

  let greenColor = UIColor(red: 10/255, green: 190/255, blue: 50/255, alpha: 1)
  let attributedStringColor : NSDictionary = [NSForegroundColorAttributeName : greenColor];


  let attributedString = NSAttributedString(string: "Hello World!", attributes: attributedStringColor as? [String : AnyObject])
  label.attributedText = attributedString

UIColor's RGB components are scaled between 0 and 1, not up to 255.

Try 

categoryTitle.textColor = [UIColor colorWithRed:(188/255.f) green:... blue:... alpha:1.0];

In Swift:

categoryTitle.textColor = UIColor(red: 188/255.0, green: ..., blue: ..., alpha: 1)

Try this one, where alpha is opacity and others is Red,Green,Blue chanels- 

self.statusTextLabel.textColor = [UIColor colorWithRed:(233/255.f) green:(138/255.f) blue:(36/255.f) alpha:1];

It is possible, they are not connected in InterfaceBuilder.

Text colour(colorWithRed:(188/255) green:(149/255) blue:(88/255)) is correct, may be mistake in connections,

backgroundcolor is used for the background colour of label and textcolor is used for property textcolor.

May be the better way is

UIColor *color = [UIColor greenColor];
[self.myLabel setTextColor:color];

Thus we have colored text
