Answer 1

NSMutableArray *jsonArr; 

ü需要添加

jsonArr = [NSMutableArray alloc] init]; 

送花儿给人初始化

Answer 2

检查这一点，

@implementation BasicProfileView 

- (void)viewDidLoad { 
    [super viewDidLoad]; 
    // Do any additional setup after loading the view from its nib. 
    jsonArr = [NSMutableArray new]; 
    [self.scrollView addSubview:_basicProfileView]; 
    [_scrollView setContentSize:self.basicProfileView.frame.size]; 

    gender=@"0"; 
    seekingGender=@"0"; 
    _basicProfileView.backgroundColor=[UIColor clearColor]; 

    } 

- (IBAction)btnContinue:(id)sender { 

[self callSignupProfileService]; 
    } 

-(void)callSignupProfileService 
{ 
NSString * post = [[NSString alloc]initWithFormat:@"userId=%@&cell_phone=%@&work_phone=%@&gender=%@&seekgender=%@&address=%@&country=%@&state=%@&city=%@&motherTongue=%@&zipcode=%@",UserId,_txtCellPhone.text,_txtWorkPhone.text,gender,seekingGender,_txtAdress.text,_WSConstCountryID,_WSConstStateID,_WSConstCityID,_WSConstLanguageID,_txtZipcode.text]; 
    NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"URL"]]; 
    RBConnect = [[RBConnection alloc]init]; 
    RBConnect.delegate = self; 
    [RBConnect postRequestForUrl:url postBody:post]; 
} 

- (void)jsonData:(NSDictionary *)jsonDict 
{ 
    [SVProgressHUD dismiss]; 

    NSMutableArray *jsonArr; 
    NSMutableDictionary *userDict,*dict; 

    jsonArr=[jsonDict objectForKey:@"DataTable"]; 

    if (jsonArr != nil && [jsonArr count] > 0) { 

    dict=[jsonArr objectAtIndex:0]; 

    userDict=[dict objectForKey:@"ABSUserProfile"]; 

    if (userDict.count>2) { 
     self.navigationController.navigationBarHidden=YES; 
     UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"Main" bundle: nil]; 

     ECSlidingViewController *newView = [mainStoryboard instantiateViewControllerWithIdentifier:@"slidingmenu"]; 
     [self.navigationController pushViewController:newView animated:YES]; 
    } 

} 

else 
{ 

    NSString *error=@"Somthing Went Wrong"; 

    [SVProgressHUD showErrorWithStatus:error]; 

} 
    } 

Answer 3

在你- (void)jsonData:(NSDictionary *)jsonDict，更改：

jsonArr=[jsonDict objectForKey:@"DataTable"]; 

到

jsonArr = [[NSMutableArray alloc] initWithArray:[jsonDict objectForKey:@"DataTable"]]; 

现在改变：

dict=[jsonArr objectAtIndex:0]; 

到：

if([jsonArr count]>0){ 
    dict=[jsonArr objectAtIndex:0]; 
    //Do whatever you want, your jsonArr is valid as it has objects 
} 
else{ 
//Perform necessary action here as your jsonArr is empty 
}
