Here is what I did:

//this is MainViewController.m (NSMutable array is already declared in .h)

myNSMutableArray = [[[NSMutableArray alloc] initWithObjects:@"object1.png", @"object2.png", @"object3.png"]retain];

- (void)ReplaceOneOfMyObjects {
    [myNSMutableArray replaceObjectAtIndex:0 withObject:@"object4.png"];
}

[self ReplaceOneOfMyObjects];

"nil" is missing:

myNSMutableArray = [[NSMutableArray alloc] initWithObjects: @"object1.png", @"object2.png", @"object3.png", nil];
