我正在编写一些类，它是 PFObject (Parse.com) 的子类。
示例：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;
}
但是当我运行时，出现了一些错误：
[PFObject setProp1:]: unrecognized selector sent to instance 0xa2707d0
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[PFObject setProp1:]: unrecognized selector sent to instance 0xa2707d0'
你能帮我解决这个问题吗？非常感谢！！！
问题解决了！！！
-(id)initWithId:(NSString*)uid {
self = [super initWithClassName:@"Photo"];
[self setObjectId:targetID];
[self fetch];
self.prop1 = [self objectForKey:@"propertiseone"];
// other
}
