ios – 从PubNub消息中检索内容

我可以使用PubNub成功发送和接收消息,当我尝试显示消息中的内容并加载UITableViewCell的UITextView时会出现问题.

第二个TEST LOG写出了我从iPhone发送的整个消息(我已经使用开发控制台尝试过了),但在此之后应用程序崩溃了.

[__NSCFDictionary length]: unrecognized SELEctor sent to instance

我知道字典有问题,但我无法弄清楚.我只使用一个NSDictionary作为我通过PubNub发送的消息,它“到达”控制台,因此我认为它正常工作.正如你在代码中看到的那样,我尝试了一些变化,但没有任何成功.

updatE

如果我发送NSString而不是NSDictionary,它会工作.

@interface ViewController ()
@property (nonatomic,strong) NSString *myIncomemessage;
@property (nonatomic,strong) NSString *messageFromDict;
@property (nonatomic,strong) NSArray *twoChAnnels;
@property (nonatomic,strong) NSDictionary *messagePbnb;
//@property (nonatomic,strong) PNmessage *messageNew;
@end

@implementation ViewController

    [super viewDidLoad];

    PNChAnnel *chAnnel_2 = [PNChAnnel chAnnelWithName:current.username shouldObservePresence:NO];
    PNChAnnel *chAnnel_1 = [PNChAnnel chAnnelWithName:self.messageRecipient shouldObservePresence:NO];

    [PubNub subscribeOnChAnnels:self.twoChAnnels];

    [PubNub requestHistoryForChAnnel:chAnnel_1 from:nil to:nil limit:100 reverseHistory:YES];
    [PubNub requestHistoryForChAnnel:chAnnel_2 from:nil to:nil limit:100 reverseHistory:YES];

    [[PNObservationCenter defaultCenter] addmessageReceiveObserver:self withBlock:^(PNmessage *messagE) {
        NSLog(@"OBSERVER: ChAnnel: %@,message: %@",message.chAnnel.name,message.messagE);

   //   self.messageFromDict = [NSString StringWithFormat:keymessage,self.messagePbnb];
   //   self.messageFromDict = [NSString StringWithFormat:keymessage,message];
    }];
