Type safe accessors for NSDictionary, better used with dictionary parsed from JSON.
Before:
id value = nil;
value = [dictionary objectForKey:@"id"];
if ([value isKindOfClass:[NSNumber class]]) {
model.identifier = [value unsignedLongLongValue];
}
value = [dictionary objectForKey:@"title"];
if ([value isKindOfClass:[NSString class]]) {
model.title = value;
}
value = [dictionary objectForKey:@"content"];
if ([value isKindOfClass:[NSString class]]) {
model.content = value;
}
Problems:
- Boilerplate code
- 64bit ids will be returned as string instead of number in some api
- Libs like RestKit even lighter JSONModel are still heavy for simple apps sometimes
What you need is just AFNetworking + NSDictionary+Accessors
After:
model.identifier = [dictionary unsignedLongLongForKey:@"id"];
model.title = [dictionary stringForKey:@"title"];
model.content = [dictionary stringForKey:@"content"];
