Question

I am having a problem setting the border colour on a UIView. If set tempColor to [UIColor lighGreyColor], [[UIColor alloc] initWithRed:0 green:0 blue:0 alpha:1.0], or [UIColor blueColor], the border gets set as expected. However, the code below does not set the colour and no border appears. unamecontainer is UIView. Any ideas why I can set the border colour to the colours mentioned above, and not the to the colour below.

UIColor *tempColor = [[UIColor alloc] initWithRed:169 green:201 blue:229 alpha:1.0];
self.unamecontainer.layer.borderColor = tempColor.CGColor;
self.unamecontainer.layer.borderWidth = 1.0;

The RGB values for UIColor need to be in the range [0, 1], so you need to divide each value by 255.0 (not 255 because that is integer division) to get a percentage:

UIColor *tempColor = [[UIColor alloc]
    initWithRed: 169/255.0
    green:       201/255.0
    blue:        229/255.0
    alpha:       1.0];
