Question

I tried to insert NSDictionary‘s in a NSMutableDictionary. There is no error but it won’t work, it remains empty.

Here’s my code:

NSMutableDictionary *einnahmen = [[NSMutableDictionary alloc] initWithCapacity:20];
NSArray *objects = [NSArray arrayWithObjects:
            name, 
            [NSNumber numberWithInt: x], 
            [NSNumber numberWithInt: y], 
            [NSNumber numberWithInt: z], 
            nil];
NSArray *keys = [NSArray arrayWithObjects:
                     @"name", 
                     @"startJahr",
                     @"zins", 
                     @"entnahmefaehig",
                     nil];
NSDictionary *entry = [NSDictionary dictionaryWithObjects:objects forKeys:keys];

[einnahmen setObject:entry forKey:@"name"]; //seems not to work

After [einnahmen setObject:entry the Debugger shows this:

I have solved this problem. The following code was in the wrong init-method:

NSMutableDictionary *einnahmen = 
              [[NSMutableDictionary alloc] initWithCapacity:20];

The compiler should show a error.
