移除指定范围的数组

 NSMutableArray * array = [NSMutableArray new];

    for (int i = 0; i < 15; i++) {

        [array addObject:@(i)];

    }

   

   

    NSLog(@"%@",array);

    NSRange  range = {10,array.count - 10};

    [array removeObjectsInRange:range];

    NSLog(@"%@",array);

 

 

比较两个数组是否相等

NSSet *seta = [NSSet setWithArray:self.selectedArray];

        NSSet *setb = [NSSet setWithArray:self.labelArray];

       

        if ([seta isEqualToSet:setb]) {

 

        } else {

 

        }
