I am trying to set my UIView's layer.borderColor property to a custom UIColor like this:
groupPageView.layer.borderColor = [UIColor colorWithRed:203.0 green:17.0 blue:17.0 alpha:1]
and it is not working. What is an easy way to accomplish this? Xcode suggests that I cast it CGColorRef, but this does not work.
像这样:
groupPageView.layer.borderColor = [[UIColor colorWithRed:203.0/255.0 green:17.0/255.0 blue:17.0/255.0 alpha:1] CGColor]
1st Ensure you imported
#import <UIKit/UIKit.h>
then add this 2 lines
groupPageView.layer.borderColor = [UIColor colorWithRed:203.0 green:17.0 blue:17.0 alpha:1].CGColor
groupPageView.layer.borderWidth =2.0;//default width =0 ; so if not set you will not see border colour
