为什么我的数组第二次为空，当我将它的第一个对象分配给目标C中的字典时，ios

Question

Occured a crazy situation. I assinged values to a mutable array in my first method.it worked properly.this is the my code for it.

for  (NSDictionary *final in SectorsArray)
{
    MoreFligh *more = [MoreFligh new];
    more.flightnumber = [final objectForKey:@"FLI_NUM"];
    more.airlinecode = [final objectForKey:@"ARL_COD"];
    more.departureairport = [final objectForKey:@"DepatureAirport"];
    more.departureday = [final objectForKey:@"DepatureDay"];
    more.departuredate = [final objectForKey:@"DepatureDate"];
    more.departuredime = [final objectForKey:@"DepatureTime"];
    more.arrivalairport = [final objectForKey:@"ArrivalAirport"];
    more.arrivalday = [final objectForKey:@"ArrivalDay"];
    more.arrivaldate = [final objectForKey:@"ArrivalDate"];
    more.arrivaltime = [final objectForKey:@"ArrivalTime"];

    [testingArray addObject:more];
}

this time testing array is not null and there are two objects with values.no problem.

then in my second method I chencked that array like this.

- (void)chk
{
    id bbbbb = testingArray.firstObject;
    NSLog(@"%@",bbbbb);
}

then it int the bbbbb (I used a breakpoint here) it had two objects with values.then I check with following code.

- (void)chk
{
    NSDictionary *bbbbb = testingArray.firstObject;
    NSLog(@"%@",bbbbb);
}

at this time it shows testing array has to objects but with no values. then I have to create a new model class assign value.otherwise after this step it shows only like no value.I have attached some pictures.if anyone wants I can provide any other details. ] 2 [ ] 3

when I create a new model, then it works properly until I checked like above.

Answer 1

- (void)chk
{
    MoreFligh *bbbbb =(MoreFligh *) testingArray.firstObject;
    NSLog(@"%@",bbbbb);
}

Answer 2

I do not understand what the testingArray is, instance variable or temporary variable?

If the instance variable that is, take a look at assignment, make sure no place makes testingArray nil or removeAllObjects.

Or show the .m file completely, let us check.
