Objectif c iOS données de passage

Question

salut je suis nouveau sur iOS et ci-dessous est mon code, je dois passer le haut que je reçois de la demande réponse ... s'il vous plaît aidez-moi je suis coincé ici première vue contrôleur est otp voir deuxième vc est verifyviewcontroller

vue Otp ch

#import <UIKit/UIKit.h> 
@interface OtpViewController : UIViewController 
@property (nonatomic, retain) NSString *str;

}

    NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]; 
    // Next up, we read the postData's length, so we can pass it along in the request. 

    NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]]; 
    // Now that we have what we'd like to post, we can create an NSMutableURLRequest, and include our postData.

à NSLog je reçois comme réponse ("succès": "1"; "BdP": "985123") J'ai besoin ce BdP pour stocker et vérifier dans page suivante s'il vous plaît aider

Answer 1

vous devez d'abord changer la propriété

de

@property (weak,nonatomic) NSArray *tmp; 

Pour

@property (strong,nonatomic) NSStirng *tmp; 

valeur Assigner à tmp comme ci-dessous

[[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]; 

Passe tmp à 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); 
}
