Body
 

Note that there are some explanatory texts on larger screens.

  1. POCore Data fails to generate primitive accessors
    text
    copied!<p>From my understanding of Core Data, all that is necessary for primitive accessors to work is the @dynamic directive for the property name (as well as declaring primitive accessors for that property within the entity implementation).</p> <p>For some reason, when using the generated primitive accessor the setState: method is <em>not</em> modifying the state property:</p> <pre><code>- (int)state { NSNumber * tmpValue; [self willAccessValueForKey:@"state"]; tmpValue = [self primitiveState]; [self didAccessValueForKey:@"state"]; return [tmpValue intValue]; } - (void)setState:(int)value { [self willChangeValueForKey:@"state"]; [self setPrimitiveState:[NSNumber numberWithInt:value]]; [self didChangeValueForKey:@"state"]; } </code></pre> <p>while using the key-value-coding version <em>does</em> modify the state property</p> <pre><code>- (int)state { NSNumber * tmpValue; [self willAccessValueForKey:@"state"]; tmpValue = [self primitiveValueForKey:@"state"]; [self didAccessValueForKey:@"state"]; return [tmpValue intValue]; } - (void)setState:(int)value { [self willChangeValueForKey:@"state"]; [self setPrimitiveValue:[NSNumber numberWithInt:value] forKey:@"state"]; [self didChangeValueForKey:@"state"]; } </code></pre> <p>in both cases, I primitive accessors are declared as follows (and as per Apple's example and code generation):</p> <pre><code>@interface Post (CoreDataGeneratedPrimitiveAccessors) - (NSNumber *)primitiveState; - (void)setPrimitiveState:(NSNumber *)value; @end </code></pre> <p>I'm a bit at a loss to why this would be. Any help would be greatly appreciated!</p>
