Hi all,
I have a class with a few convenience constructors which take an
NSError ** as a parameter:
+ (id)patchWithContentsOfFile:(NSString *)path error:(NSError **)
outError
{
return [[[self alloc] initWithContentsOfURL:[NSURL
fileURLWithPath:path] error:outError] autorelease];
}
- (id)initWithContentsOfURL:(NSURL *)patchURL error:(NSError **)
outError
{ // Stuff }
The 'return' line always generates a warning:
passing argument 2 of ‘initWithContentsOfURL:error:’ from distinct
Objective-C type
I've tried explicitly casting outError to (NSError **) and a couple
of other things. I'm using GCC 4.0.1 (it also happened on 4.0.0).
What can I do to silence the warning?
Did you forget to declare the -initWithContentsOfURL:error:
constructor in your interface? If you'd done that, and there was
already a constructor with a similar name in a base class but with
different type parameters, you might get that message.
Kind regards,
Alastair.
