升級到0.10.0後RestKit崩潰

Question

我似乎能夠使用傳統的loadobjectsatresourcepath：delegate：方法啓動restkit，並且加載對象。但是，當我介紹塊時：^ {}，restkit每次崩潰。

[[RKObjectManager sharedManager] loadObjectsAtResourcePath:@"/api/v1/places" delegate:self block:^(RKObjectLoader* loader) { 
    loader.objectMapping = [[RKObjectManager sharedManager].mappingProvider objectMappingForClass:[Place class]]; 
}]; 

我得到這個在日誌中：

2012-05-12 19:07:32.266 App - [RKObjectManagerloadObjectsAtResourcePath:delegate:block:]: unrecognized selector sent to instance 0x3aa2e0 
2012-05-12 19:07:32.268 App - *** Terminating app due to uncaught exception 'NSInvalidArgumentException', 
reason: '-[RKObjectManager loadObjectsAtResourcePath:delegate:block:]: unrecognized selector sent to instance 0x3aa2e0' 

如何解決這個問題有什麼想法？謝謝！

異常告訴你問題是什麼：RKObjectManager不響應loadObjectsAtResourcePath:delegate:block:。快速瀏覽API文檔顯示the original method不再存在於0.10.0中，似乎已被替換爲loadObjectsAtResourcePath:usingBlock:。

您應該能夠通過使用新的方法，以避免該異常：

[[RKObjectManager sharedManager] loadObjectsAtResourcePath:@"/api/v1/places" usingBlock:^(RKObjectLoader* loader) { 
    loader.objectMapping = [[RKObjectManager sharedManager].mappingProvider objectMappingForClass:[Place class]]; 
}];
