Ios -[u NSArrayI objectAtIndex:]：索引1超出范围[0..0]'；

我有以下问题。请帮我做这个。短暂性脑缺血发作

@implementation BasicProfileView

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.

    [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"];
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];

}
  }

你需要补充吗

NSMutableArray *jsonArr;

始终初始化

检查此项

jsonArr = [NSMutableArray alloc] init];

在您的

-（void）jsonData:（NSDictionary*）jsonDict

中，更改：

@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];

}
  }

到

现在改变：

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

致：

---

首先查看此打印

jsonArr

，查看其是否为零或没有数据

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

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

dict=[jsonArr objectAtIndex:0];

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
}
