RestKit 和 Swift 错误响应描述符

Question

我添加了作为函数结果的响应描述符

class func responseDescriptors() -> [RKResponseDescriptor] {
        var successCodes : NSIndexSet = RKStatusCodeIndexSetForClass(RKStatusCodeClass.Successful);

        var retResponseDescriptors : [RKResponseDescriptor] = [];

        //Settings
        retResponseDescriptors.append(RKResponseDescriptor(mapping: BBLocalization.mapping(), method: RKRequestMethod.GET, pathPattern: BBServerAPIPaths.Settings.LanguageTranslate.rawValue, keyPath: nil, statusCodes: successCodes));
        retResponseDescriptors.append(RKResponseDescriptor(mapping: BBWakeUP.mapping(), method: RKRequestMethod.GET, pathPattern: "v1.2/user/wakeup", keyPath: nil, statusCodes: successCodes));

        //User
        retResponseDescriptors.append(RKResponseDescriptor(mapping: BBUser.mapping(), method: RKRequestMethod.GET, pathPattern: "v1.2/user/:userId", keyPath: nil, statusCodes: successCodes));

        return retResponseDescriptors;
    }

通过调用添加

RKObjectManager.sharedManager().addResponseDescriptorsFromArray(self.responseDescriptors());

映射响应本地化效果很好，但如果我调用wakeUp，它会映射到

to object <BBUser: 0x7fbe306b1210>

如果我没有为用户请求添加响应描述符

//User
//retResponseDescriptors.append(RKResponseDescriptor(mapping: BBUser.mapping(), method: RKRequestMethod.GET, pathPattern: "v1.2/user/:userId", keyPath: nil, statusCodes: successCodes));

效果很好，映射到 BBWake 工作中。

在 ObjectiveC 中不会发生此错误。

为什么？

映射：

BBWakeUP

class func mapping() -> RKObjectMapping {
    var mapping : RKObjectMapping = RKObjectMapping(forClass: BBWakeUP.self);
    mapping.addAttributeMappingsFromDictionary(["localization_hash" : "localizationHash"]);
    return mapping;
}

BB用户

class func userMapping() -> RKEntityMapping {
    var mapping = RKEntityMapping(forEntityForName: "BBUser", inManagedObjectStore: RKManagedObjectStore.defaultStore());
    mapping.identificationAttributes = ["userId"];
    mapping.addAttributeMappingsFromDictionary(["id" : "userId"]);
    return mapping;
}

Answer 1

在objective-c 中你应该看到完全相同的行为，因为pathPattern: "v1.2/user/wakeup" 和pathPattern: "v1.2/user/:userId" 就模式匹配器而言是相同的。所以，无论哪个先注册，都会先被使用。

如果您的 obj-c 正在工作，那么它的指定方式会有所不同。
