Issue with using RGB colors in IOS

Question

I want to use RGB color to set set background color of UIButton.

I have lots of UIButtons so I decided to make a custom class.But when I try to use colorWithRed I am getting error.

First Code:

[self.layer setBackgroundColor:[UIColor colorWithRed:60/255.0f green:146/255.0f blue:180/255.0f alpha:1.0f]];

Error

enter image description here

Second Code

  self.layer.backgroundColor = [UIColor colorWithRed:60/255.0f green:146/255.0f blue:180/255.0f alpha:1.0f];

Error

enter image description here

Read the error message! A layer's background color is a CGColor, not a UIColor. — matt, May 04 '15 at 05:55

try to use this code

self.layer.backgroundColor = [UIColor colorWithRed:60/255.0f green:146/255.0f blue:180/255.0f alpha:1.0f].CGColor;

You need to convert UIColor to CGColor which can be done by above code.

Hope this will solve your problem

layer backgroundcolor is of cgcolorref type, so cant use uicolor. we need to use cgcolor or convert uicolor to cgcolor and use it.

example:

[[UIColor whiteColor] CGColor];

or

[UIColor whiteColor].CGColor;
