Question

How do I wrap a BOOL in an object type in Objective-C?

I want to store a BOOL in the userInfo object of an NSTimer. How do I wrap it?

Answer 1

NSNumber *boolForUserInfo = @YES; // or [NSNumber numberWithBool:YES] the old way
[userInfo setObject:boolForUserInfo forKey:@"myBool"];

Retrieve with:

[[userInfo objectForKey:@"myBool"] boolValue];
