How to find If array contains two or more objects

Question

I'm attempting to implement the containsObject but with two or more parameters, is this possible?

Currently I've got:

and apparently there's too many arguments. I've delved through Apple's docs but I'm yet to find anything. Any suggestions?

if ([ myArray containsObject:@"1", @"2"]){
    NSLog(@"if");
} else if([ myArray containsObject:@"1", @"2",@"3",@"4"]) {
   NSLog(@"else if");
}else if([ myArray containsObject:@"1", @"2",@"3"]) {
   NSLog(@"else");
}

myArray:-

myArray is (
    1,
    2,
    3,
    4
)

Answer 1

you can check subsets of array

 NSArray *arry1= [NSArray arrayWithObjects:@"1",@"2",@"3",@"4", nil];
        NSArray *arry2= [NSArray arrayWithObjects:@"1",@"2", nil];

        NSSet *set1 = [NSSet setWithArray:arry1];
        NSSet *set2 = [NSSet setWithArray:arry2];

        if ([set2 isSubsetOfSet:set1])
        {
            NSLog(@"array1 contains all elements of array 2");
        }else{
            NSLog(@"array1 does not contains all elements of array 2");
        }

Answer 2

if ([myArray containsObject:@"1"] || [ myArray containsObject: @"2"]) {
    NSLog(@"if");
} else {
   NSLog(@"else");
}

You need to write your own custom code. Pass all the required objects in method as an array and iterate over the array of all objects. If any object is not found, return false .

-(BOOL)containsObjects:(NSArray*)arrObj
{
    BOOL result = YES;
    for(CustomObject *cObj in arrObj) {
        result = [mainArray containsObject:cObj];
        if(result == NO) {
            break;
        }
    }

    return result;
}
