Hi Julio,
I guess you can create a static instance of the class and use it (kind
of a singleton).
static myClass *sharedInstance = nil;
+(void)myClassMethod:(NSString*)myPath {
if(sharedInstance == nil)
sharedInstance = [[myClass alloc] init];
[[sharedInstance myTextView]
replaceCharactersInRange:NSMakeRange(0,[[[sharedInstance myTextView]
string] length]) withRTF:myData];
}
Regards
Sarat
