Question

OK, I’m a little confused.
It’s probably just a triviality.

I’ve got a function which looks something like this:

- (void)getNumbersForNews:(BOOL)news andMails:(BOOL)mails {
NSMutableDictionary *parameters = [[NSMutableDictionary alloc] init];
[parameters setValue:news  forKey:@"getNews"];
[parameters setValue:mails forKey:@"getMails"];...}

It doesn’t matter whether I use setValue:forKey: or setObject:ForKey:, I’m always getting a warning:

“Passing argument 1 of set… makes pointer from integer without a cast”…

How on earth do I insert a bool into a dictionary?

Answer 1

Values in an NSDictionary must be objects. To solve this problem, wrap the booleans in NSNumber objects:

[parameters setValue:[NSNumber numberWithBool:news] forKey:@"news"];
[parameters setValue:[NSNumber numberWithBool:mails] forKey:@"mails"];
