objective c - Can not change UILabel text color

Question

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.

Answer 1

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)
