我有两个不同的数组与一些重复的字符串,我想创建一个只有唯一字符串的新数组.

例如,取这两个数组:

NSArray *array1 = [[NSArray alloc] initWithObjects:@"a",@"b",@"c",nil]; 
NSArray *array2 = [[NSArray alloc] initWithObjects:@"a",@"d",@"c",nil];

// Result should be an array with objects "b", and "d" 
// since they are the only two that are not repeated in the other array.
