我有一个与服务器一起使用的应用程序.
我想创建一个离线模式,即当用户创建某些内容或更改它在某处保存时,然后当出现互联网连接时 – 这些请求将转到服务器.我怎样才能做到这一点？如何在NSUserDefaults中存储块？如何不丢失指向这些块的指针？
它可以是不同的控制器.请帮帮我.我为我糟糕的英语道歉.
我试图在NSUserDefaults中保存这些对象

我试图在NSUserDefaults中保存这些对象
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];
但我的块属性变为null
