Question

I’m writing some class with is subclass of PFObject (Parse.com).

Example:
LBSomeClass.h

@interface LBSomeClass : PFObject
@propertise (strong,nonatomic) NSString* prop1;
@propertise (strong,nonatomic) NSString* prop2;
-(id)init;
-(id)initWithId:(NSString*)uid;
@end

LBSomeClass.m

@implementation LBPhoto
@synthesize prop1;
@synthesize prop2;

-(id)init {
self = [super init];
return self;
}

-(id)initWithId:(NSString*)uid {
self = [super init];
PFQuery* query = [PFQuery queryWithClassName:@"someclass"];
self = (LBSomeClass*)[query getObjectWithId:uid];

self.prop1 = [self objectForKey:@"propertiseone"]; //error here
self.prop2 = [self objectForKey:@"propertisetwo"]; //error here

return self;
}

But when i run, there’re some error:

[PFObject setProp1:]: unrecognized selector sent to instance 0xa2707d0
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[PFObject setProp1:]: unrecognized selector sent to instance 0xa2707d0'

Can you help me to solve that? Thanks so much!!!

Problems solved!!!

-(id)initWithId:(NSString*)uid {
self = [super initWithClassName:@"Photo"];
[self setObjectId:targetID];

[self fetch];

self.prop1 = [self objectForKey:@"propertiseone"];
// other
}
