Question

我正在与Restkit同时发送2个请求，并且我从两个请求中都收到了响应，但只有一个请求接收到任何对象。如果我逐个发送它们，那么我的objectloader将接收所有对象。

第一次请求：

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];
}];

第二次请求：

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];
}];

我的目标：

-(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]);
    }

}

更新：设置我的基本网址

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

解决方案

问题是我使用了两个对象管理器的共享管理器，所以我最终做了：

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;

使用块语法加载，

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);
   }
}];

修改

使用您自己的对象管理器并保留它，然后以这种方式使用它，

不要使用sharedManager来代替alloc / init，并提供objectstore并查看。希望这对你有帮助，

[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); }; }];

在Restkit中未在第二个请求上加载的对象
