Question

I am new to iPhone SDK.I am printing each and every array in console.No matter how much data consume.and I note that some times my application is crashing.it gives me BAD_ACCESS and pointer showing on my NSLog line.I am confused can NSLog crash the application?
Here is my code :

for (int i = 0; i < [UserNeedListArray count]; i++) {
    EndUserNeed* aEndUser = [UserNeedListArray objectAtIndex:i];
    if ([appData.CurrentUser.userId isEqualToString:aEndUser.UserId]) {
        NSMutableArray* temp = [[NSMutableArray alloc]init];
        [temp addObject:aEndUser];
        NSLog(@"%@",temp);
        [arr_ShowMyOnly addObject:[temp objectAtIndex:0]];
        NSLog(@"%@",arr_ShowMyOnly);
        [temp removeAllObjects];
        [temp release];
        temp = nil;
    }
}

Please help me.Thanking you…

Yes it can. when you do NSLog(@"%@",temp); it expects that temp is a type of NSString class.

In your case you should do NSLog(@"%@",[temp description]); Almost all the classes have a description method that will return you an NSString object.
