Question

Hallo ich bin neu bei iOS und unten ist mein Code Ich muss die Spitze, die ich von Anfrage erhalten Antwort ... bitte helfen Sie mir, ich bin hier stecken erste Ansicht Controller ist otp Ansicht zweiten vc ist verifyviewcontroller

Erste Hilfe benötigen Sie Eigenschaft ändern

Von

@property (weak,nonatomic) NSArray *tmp; 

Um

@property (strong,nonatomic) NSStirng *tmp; 

zuordnen Wert tmp wie unten

[[session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) { 
      NSString *requestReply = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding]; // this is json string 
      NSError *error; 
      NSDictionary *jsonDict = [NSJSONSerialization JSONObjectWithData:data options:0 error:&error]; // you need to convert to dictionary object 

      NSLog(@"requestReply: %@", jsonDict); 
      self.tmp=[jsonDict valueForKey:@"otp"] ; // you need to extract value using the key [requestReply valueForKey:@"otp"]; 
      NSLog(@"%@",self.tmp); 

    }] resume]; 

Pass tmp VerifyVIewController

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(nullable id)sender{ 

VerifyViewController *loadCtr = (VerifyViewController *)segue.destinationViewController; 
loadCtr.delegate = self; 
loadCtr.tmpStr = self.tmp; 
NSLog(@"passing val: %@",_tmp); 
}
