Answer 1

Yeah, no checkbox for you in iOS (-:

Here, this is what I did to create a checkbox:

UIButton *checkbox; BOOL checkBoxSelected; checkbox = [[UIButton alloc] initWithFrame:CGRectMake(x,y,20,20)]; // 20x20 is the size of the checkbox that you want // create 2 images sizes 20x20 , one empty square and // another of the same square with the checkmark in it // Create 2 UIImages with these new images, then:  [checkbox setBackgroundImage:[UIImage imageNamed:@"notselectedcheckbox.png"]                     forState:UIControlStateNormal]; [checkbox setBackgroundImage:[UIImage imageNamed:@"selectedcheckbox.png"]                     forState:UIControlStateSelected]; [checkbox setBackgroundImage:[UIImage imageNamed:@"selectedcheckbox.png"]                     forState:UIControlStateHighlighted]; checkbox.adjustsImageWhenHighlighted=YES; [checkbox addTarget:(nullable id) action:(nonnull SEL) forControlEvents:(UIControlEvents)]; [self.view addSubview:checkbox]; 

Now in the target method do the following:

-(void)checkboxSelected:(id)sender {     checkBoxSelected = !checkBoxSelected; /* Toggle */     [checkbox setSelected:checkBoxSelected]; } 

That's it!

On iOS there is the switch UI component instead of a checkbox, look into the UISwitch class. The property on (boolean) can be used to determine the state of the slider and about the saving of its state: That depends on how you save your other stuff already, its just saving a boolean value.
