Question

I have an array with two blank characters as follows:

shuffleArray = [[NSMutableArray alloc] initWithObjects:@"H",@"E",@"",@"",@"O", nil];

Now I want to assign the values of array to unichar for further coding as follows:

for(int i=0; i<[shuffleArray count]; i++)
{
       NSString *temp = [shuffleArray objectAtIndex:i];
        NSLog(@"string:%@",temp);
        unichar c = [temp characterAtIndex:0];
}

it prints “H” and “E” fine but when it found blank characters i.e. @”” .

It gets crash at the point

unichar c = [temp characterAtIndex:0];

How can I solve this problem.

Any help will be appriciable.

Thanx in advance..

try this out it works

  for( NSString *temp in shuffleArray )
  {
    NSLog(@"string:%@",temp);
    if (temp.length) {
      unichar c = [temp characterAtIndex:0];
    }
  }
