Why are you use self.array ? Only write like this. [array addObject:photoID]; — Dipen Chudasama

if you want to use the array in a parent scope, probably you have to define the array in the parent scope. does is make sense to you? — holex

for adding NSString in NSMutableArray is like this

NSString *str = @"object";
NSMutableArray *loArr = [[NSMutableArray alloc] init];
[loArr addObject:str];

In your code Why are you using self.array ? just write like this. [array addObject:photoID];

self keyword is used for global variables but here in your code "array" is a local variable .So need of self.array

[array addObject:photoID];

Before adding check that photoID is nil or not

 if (photoID.length > 0) {
        [array addObject:photoID];
    }

I observe that in your code. you declare mutable array in local scope.

So just use

 [array addObject:photoID];

Instead of 

   [self.array addObject:photoID];

May be you are create property for this array with same name, then you need to alloc it.

If you create a property for this then remove local declaration and alloc array like this.

 self.array=[[NSMutableArray alloc]init];

and then use

   [self.array addObject:photoID];
