UIImage unrecognized selector sent to instance

I have the 'classic' error:

unrecognized selector sent to instance.

If I read through other comparable questions it should be memory related, however I can't find out what I'm doing wrong.

Here is what I try to do:

I use the brilliant code of Trevor

This is my code:

The roundedCornerImage:borderSize: is giving the trouble

NSInteger my_borderSize = 0.1;
UIImage *Image_large = [image_sel croppedImage:CGRectMake((my_width/2) -(my_height*0.66)/2, 0, my_height*0.66, my_height) ];
UIImage *roundedCornerImage_temp = [Image_large roundedCornerImage:0.8 borderSize:my_borderSize];

That method is not in Apple's UIImage class. They are extensions to UIImage written by the guy whose code you link to.

You need to make sure to add UIImage+RoundedCorner.h and UIImage+RoundedCorner.m to your Xcode project, and then in the class where you want to use roundedCornerImage:borderSize:, you should

#import "UIImage+RoundedCorner.h"

Also, I notice that you're passing in decimal values for both cornerSize and borderSize. Those are supposed to be NSInteger values, per Trevor's API. I would guess that those are in display points, but apparently, he limited it to integer values.

Update: also make sure that the UIImage+RoundedCorner.m file is listed among your Compile Sources:
