Question

Sorry if this is basic, but I can’t get my head around this. I have an array and would like to go through every single object in it and see if it isEqualToString:@”something”. If tried this, but it will crash:

    for (int i = 0; i < ([myNSMutableArray count]); i++) {

    NSLog(@"i = %i", i);

    if ([[myNSMutableArray objectAtIndex:i] isEqualToString:@"something"]) {
        ...
    } else {
        ...
    }


}

I’ll get:

    2011-07-14 13:38:40.983 MNs[21416:207] i = 0
2011-07-14 13:38:40.985 MNs[21416:207] -[__NSArrayM isEqualToString:]: unrecognized selector sent to instance 0x4c976f0
2011-07-14 13:38:40.987 MNs[21416:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSArrayM isEqualToString:]: unrecognized selector sent to instance 0x4c976f0'

Any help would be very much appreciated. Thanks in advance!

EDIT:

Sorry, I forgot. This is how I created the array:

NSMutableArray *myNSMutableArray = [[NSMutableArray alloc] init];

    for (int x = 0; x < 30; x++) {
        [myNSMutableArray addObject:@""];
        [myNSMutableArray addObject:@"something"];
        [myNSMutableArray addObject:@""];
    }

EDIT2:

So sorry, the problem was that I tried to copy a mutable array … so all of your answers are correct, I just need to pick one now, I guess.

Try This,

for (int i = 0; i < ([myNSMutableArray count]); i++) {

    NSLog(@"i = %i", i);

NSString *stringToCheck = (NSString *)[myNSMutableArray objectAtIndex:i];

    if ([stringToCheck isEqualToString:@"something"]) {
        ...
    } else {
        ...
    }


}
