自定义init parse.com

我正在写一些类是PFObject（Parse.com）的子类。自定义init parse.com

例子： 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; 
}

但是当我运行，里有一些错误：

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

你能不能帮我解决？非常感谢！！！

问题解决了！由我

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

[self fetch]; 

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