cocoa - Objective-C: Why is my object being instantiated as __NSMallocBlock__? -


i running strange problem trying dynamically create new instance of class property (arrayclass) have set , stored previously:

nsobject *instance = [[self.arrayclass alloc] init]; if ( ![instance iskindofclass:self.arrayclass] )     nslog(@"say what?!");

if break , log self.arrayclass, shows proper class on console (in case, called store), when attempt create instance of dynamically , log type of instance, showing class __nsmallocblock__.

what heck going on??

it turns out silly mistake indeed. had somehow created empty init method in class trying instantiate, had forgotten implement (or return anything). strangely, compiler didn't complain this.

here's empty init method looked like:

- (instancetype)init {  }

obviously since i'm not defining or returning self, runtime doesn't object init expects. does get, oddly enough, comes __nsmallocblock__ type, , trying pretty object result in crash.
