如何编写IF ELSE来检查数组的字符串内容？

Question

I'm trying to write an IF ELSE statement to enable shipping, If user doesn't add an address the array contents remain as "-" & "-" for the two items in the array. I want to check to see if those are in the array, if they are then I want to enableshipping.

Here is the code for getting the array:

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *fullFileName = [NSString stringWithFormat:@"%@/arraySaveFile", documentsDirectory];
NSMutableArray *array = [[NSMutableArray alloc] initWithContentsOfFile:fullFileName];

How do I write this first line to look for the "-" & "-"?

if ([fullFileName isEqualToString:@"-","-"]) 
{
[nnNEP EnableShipping];
}
else {
    [nnNEP DisableShipping];
}

Thanks,

michael

I think you want to check the contents of the first two items of the array and not fullFileName.

For example:

if ([[array objectAtIndex:0] isEqualToString:@"-"] 
      && [[array objectAtIndex:1] isEqualToString:@"-"])
{
    [nnNEP EnableShipping];
}
else
{
    [nnNEP DisableShipping];
}
