Question

I want to pass two arguments to method with NSThread. I tried using this third answer. But unfortunatlly that code was not working well because andKeys:
method is not available.

   [NSThread detachNewThreadSelector:@selector(DownloadCheckServerPath:DirectoryName:) toTarget:self withObject:"How to pass two objects"];

So how should I called -(void)DownloadCheckServerPath:(NSString *)serverPath DirectoryName:(NSString *)directoryName this method in Sector through NSThread. ?

You can’t pass multiple arguments to a method which is invoked by this message send. Workaround: use collections. One argument is more than enough.

- (void)reallyCallMethod:(NSDictionary *)dict
{
    [self downloadCheckServerPath:dict[@"path"] directoryName:dict[@"dir"]];
}

[NSThread detachNewThreadSelector:@selector(reallyCallMethod:)
                         toTarget:self
                       withObject:@{ @"path" : @"/foo/bar", @"dir" : @"baz" }];

Also: don’t begin selector names with capital letters. That’s for classes only (and it’s really ugly, isn’t it?)
