Question

我似乎能够正常启动restkit并使用传统的loadobjectsatresourcepath：delegate：方法加载对象。但是，当我引入块：^ {}时，restkit每次都会崩溃。

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

我在日志中得到了这个：

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'

有关如何解决此问题的任何想法？谢谢！

该例外确切地告诉您问题所在：RKObjectManager不响应loadObjectsAtResourcePath:delegate:block:。快速浏览API文档可以发现{0}已不再存在于0.10.0中，并且似乎已被the original method替换。

您应该能够通过使用新方法来避免异常：

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

升级到0.10.0后，RestKit崩溃
