Question

Answer 1

+1 A:

If lpath is of type NSString then you should use %@. It is used every time you need to convert a Cocoa object (or any other descendant of NSObject) into its string representation.

smallURL:(@"bundle://%@", [visuel lpath])

It seems to work, thanks. Now I have another problem and I don't know why, when I use what you told me the picture don't want to display and if I use NSLog(@"bundle://%@", [visuel lpath]); the path for the picture is good --> bundle://image.jpg

I beleive that Niels Castle has already answered that question in his comment to the Hoang's answer. The right decisiion is to use the syntax suggested by Hoang.

Thanks its working now, but why do I have to pecify NSString again? I don't understand.

NSLog is special. It supports recieving both a string with a format and its parameters. smallURL only takes one parameter, a string. In order for the single parameter to smallURL to be correctly formatted we have to first create a new string with a format and then pass the resulting foratted string to smallURL.
