iOS:在离线中列出HTTP请求的队列



我有一个可与服务器一起使用的应用程序。我想创建一个离线模式,即用户创建某些东西或更改的东西,然后将其保存在某个地方,然后出现Internet连接时 - 这些请求转到服务器。我该如何实现?如何将块存储在NSUserDefaults中?如何不为这些块失去指针?它可以是不同的控制器。请帮帮我。我为我的英语不好道歉。我尝试将此对象保存在NSUserDefaults

typedef void (^ExecutionBlock)(void);
@interface OfflineBlockObject : NSObject
@property (nonatomic, copy) ExecutionBlock block;
@property (nonatomic, strong) NSArray<NSMutableArray *> *operandsArray;
@property (nonatomic, strong) NSArray *conditionsArray;
@end
OfflineBlockObject *blockObject = [[OfflineBlockObject alloc] init];
        BOOL first = [self.reservation.reservationID boolValue];
        NSArray *conditions = @[@(first), @(self.shouldCallSetTagsForReservation)];
        NSArray *operands = @[@[[self.reservation json], self.reservation.reservationID ? : @0, self.selectedTags ? : @[]],
                              @[[self.reservation json], @(self.shouldForceApproved), self.selectedTags? : @[]]];
        blockObject.conditionsArray = [conditions copy];
        blockObject.operandsArray = [operands copy];
        @weakify(blockObject);
        blockObject.block = [^{
            @strongify(blockObject);
            if ([blockObject.conditionsArray[0] boolValue]) {
                ReservationsModel *m = [[ReservationsModel alloc] init];
                [m editReservation:blockObject.operandsArray[0][0] success:^(id responseObject) {
                    if ([blockObject.conditionsArray[1] boolValue]) {
                        [m setReservationTags:blockObject.operandsArray[0][1] tags:blockObject.operandsArray[0][2] success:nil failure:nil];
                    }
                } failure:nil];
            } else {
                self.reservation.eventId = self.reservationEvent.eventInfoID;
                ReservationsModel *m = [[ReservationsModel alloc] init];
                [m createReservation:blockObject.operandsArray[1][0] shouldForceApproved:[blockObject.operandsArray[1][1] boolValue] success:^(id responseObject) {
                    Reservation *reservation = [Reservation reservationWithJson:responseObject];
                    if (reservation.reservationID) {
                        if ([blockObject.conditionsArray[1] boolValue]) {
                            [m setReservationTags:reservation.reservationID tags:blockObject.operandsArray[0][2] success:nil failure:nil];
                        }
                    }
                } failure:nil];
            }
        } copy];
        [[OfflineQueueHelper sharedHelper] addTask:blockObject];

但是我的块属性变为null :(

,所以我有一个做到这一点的POD,但是它在迅速(OBJ -C使界面太过令人费解( - https://cocoapods.orgs.org/pods/offlineerequestmanager。您可以制作任何符合OfflineRequest的对象,以包装您要将其送入服务器的任何网络请求。如果您想确保通过应用程序终止持续存在,则还可以提供将其写入磁盘的字典。我们已经在内部应用程序中使用了一段时间了,因此希望其他人可以从中使用一些。

最简单的用例将看起来像以下内容,尽管大多数实际情况(保存到磁盘,特定的请求数据等(将有更多的箍可以跳过:

import OfflineRequestManager
class SimpleRequest: OfflineRequest {
    func perform(completion: @escaping (Error?) -> Void) {
        doMyNetworkRequest(withCompletion: { response, error in
            handleResponse(response)
            completion(error)
        })
    }
}
///////
OfflineRequestManager.defaultManager(queueRequest: SimpleRequest())
