Re: Cannot get indexOfObject to work

The problem is that the object @"caption" is NOT an object of your custom class...

So if indexOfObject sends an isEqual message to it, it is the isEqual of NSString class that is executed not yours !

Le 19 Mar 2004, ` 20:16, Bartlomiej Cichosz a icrit :

I have a custom class (let's call it CL) derived from NSObject, which
implements isEqual: - currently, for debugging purposes it is defined
as:

- (BOOL)isEqual:(id)anObject {
NSLog(@"isEqual called");
return YES;
}

I also have an NSMutableArray containing number of CL objects. I am
trying to use indexOfObject to locate particular object, but I get
NSNotFound regardless of what I am searching for. My code looks as
follows:

if([[a objectAtIndex:6] isEqual:@"caption"]) {
NSLog(@"Yes, they are the same");
}


i=[a indexOfObject:@"caption"];
if(i==NSNotFound) {
NSLog(@"Not found");
}


Variable a is the NSMutableArray I mentioned. The output I get is:

2004-03-19 13:57:29.435 App[8533] isEqual called
2004-03-19 13:57:29.435 App[8533] Yes, they are the same
2004-03-19 13:57:29.435 App[8533] Not found
