You can check this way also...

if self.yourMutableArray.count == 0 {
     // Your Mutable array is empty. 
} else {
    // Your Mutable array is not empty.
}

There are multiple ways to check it.

  1. if (array == [NSNull null])
{
    //myarray is blank
}

  2. if(array.count==0)
{
    //myarray is blank
}

  3. if(array == nil)
{
    //my array is blank
}

//if the array has a count of elements greater than 0, then the array contains elements
if(myarray.count>0){
    NSlog(@"myarray contains values/elements");
}
else{ //else the array has no elements
    NSlog(@"myarray is nil");
}

If you want to check if it is empty:

if ([myMutableArray count] == 0) { ... }

If you want to check if the variable is nil:

if (!myMutableArray) { ... }

or:

if (myMutableArray == nil) { ... }
