Restkit中的第二個請求沒有加載的對象

Question

我使用Restkit同時發送了2個請求，並且我收到來自它們兩個的響應，但只有一個請求接收到任何對象。如果我逐一發送它們，那麼我的objectloader會收到所有對象。

第一個請求：

self.firstObjectManager = [RKObjectManager sharedManager]; 
[self.firstObjectManager loadObjectsAtResourcePath:[NSString stringWithFormat: @"/%@.json", subUrl] usingBlock:^(RKObjectLoader *loader){ 
    [loader.mappingProvider setObjectMapping:designArrayMapping forKeyPath:@""]; 
    loader.userData = @"design"; 
    loader.delegate = self; 
    [loader sendAsynchronously]; 
}]; 

第二個請求：

self.secondObjectManager = [RKObjectManager sharedManager]; 
[self.secondObjectManager loadObjectsAtResourcePath:[NSString stringWithFormat: @"/%@.json", subUrl] usingBlock:^(RKObjectLoader *loader){ 
    [loader.mappingProvider setObjectMapping:designerMapping forKeyPath:@""]; 
    loader.userData = @"designer"; 
    loader.delegate = self; 
    [loader sendAsynchronously]; 
}]; 

我objecloader：

-(void)objectLoader:(RKObjectLoader *)objectLoader didLoadObjects:(NSArray *)objects 
{ 
    //NSLog(@"This happened: %@", objectLoader.userData); 
    if (objectLoader.userData == @"design") { 
     NSLog(@"Design happened: %i", objects.count); 
    }else if(objectLoader.userData == @"designer"){ 
     NSLog(@"designer: %@", [objects objectAtIndex:0]); 
    } 

} 

我的回答是：

更新：設置我基本URL

RKURL *baseURL = [RKURL URLWithBaseURLString:@"http://iphone.meer.li"]; 
[RKObjectManager setSharedManager:[RKObjectManager managerWithBaseURL:baseURL]]; 

解決方案

問題是，我同時用於對象管理的共享管理器，所以我結束up做：

RKURL *baseURL = [RKURL URLWithBaseURLString:@"http://iphone.meer.li"]; 
RKObjectManager *myObjectManager = [[RKObjectManager alloc] initWithBaseURL:baseURL]; 
self.firstObjectManager = myObjectManager; 

和：

RKURL *baseURL = [RKURL URLWithBaseURLString:@"http://iphone.meer.li"]; 
RKObjectManager *myObjectManager = [[RKObjectManager alloc] initWithBaseURL:baseURL]; 
self.secondObjectManager = myObjectManager; 

Answer 1

加載使用塊語法，

self.secondObjectManager = [RKObjectManager sharedManager]; 
[self.secondObjectManager loadObjectsAtResourcePath:[NSString stringWithFormat: @"/%@.json", subUrl] usingBlock:^(RKObjectLoader *loader){ 
    [loader.mappingProvider setObjectMapping:designerMapping forKeyPath:@""]; 
    loader.userData = @"designer"; 
    loader.onDidLoadObjects = ^(NSArray *objects){ 
     NSLog(@"Loaded objects %@", objects); 
     }; 
    loader.onDidFailedWithError = ^(NSError *error){ 
     NSLog(@"Failed with error %@", error.userInfo); 
    } 
}]; 

編輯

使用您自己的對象管理器，並保留它，然後使用這種方式，

不要使用sharedManager來代替alloc/init它並提供對象存儲並查看。希望這可以幫助你，

[self.objectManager loadObjectsAtResourcePath:resourcePath usingBlock:^(RKObjectLoader *loader){ 
     [loader.mappingProvider setMapping:[MyClass mapping] forKeyPath:@""]; 
     loader.onDidLoadObjects = ^(NSArray *objects){ 

     }; 
     loader.onDidLoadResponse = ^(RKResponse *response){ 
      NSLog(@"Loaded response %@", response.bodyAsString); 
     }; 
     loader.onDidFailLoadWithError = ^(NSError *error){ 
      NSLog(@"Error occurred ... %@", error.userInfo); 

     }; 
    }];
