Question

If i add an object to a property “dreamsArr”, which is NSMutableArray:

@synthesize dreamsArr;

-(void) viewDidLoad
{
    Dream *d1 = [[Dream alloc] init];
    d1.title = [[NSString alloc] initWithString:@"my 1st dream"];

    self.dreamsArr = [[NSMutableArray alloc] init];
    [self.dreamsArr addObject:d1];

    Dream *dr = [self.dreamsArr objectAtIndex:0];
    NSString *title=dr.title;

    const char *chTitle = [title UTF8String]; 
    NSLog(@"%s", chTitle);
}

Why does NSLog print “null”?
when i trace this code, after [self.dreamsArr addObject:d1] , dreamsArr still empty, why?

Answer 1

problem was in the other part of code
