判断两个数组中是否有不同的元素

NSArray *selectTure = [@"数组一" filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"SELF in %@", @"数组二"]];

NSArray *unselectTure = [@"数组一" filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"NOT (SELF in %@)", selectTure]];

if (unselectTure.count >= 1) {

NSLog(@"两个数组中有不同的元素-> %@", unselectTure);

}else{

NSLog(@"两个数组中没有不同的元素-> %@", unselectTure);

}
