how to implement two or more checkbox in one viewcontroller, when one of them is checked then all other have to be unchecked automatically ? any help @Boris-Em ?

Here you can download a video that shows the problem: https://dl.dropboxusercontent.com/u/8581359/check_box_usage.mp4

Untill I show an UIAlertController, the behavior is correct, but as soon as I show it, the disabled animation brokes.

Here is the didTapCheckBox event:

-(void)didTapCheckBox:(id)sender {
    BEMCheckBox *checkBox = (BEMCheckBox*)sender;

    SpaceTargetInfoV2 *spaceTarget;
    for(SpaceTargetInfoV2 *st in self.spaceTargetListResponse.spaceTargetList) {
        if(st.idSpaceTarget == checkBox.tag) {
            spaceTarget = st;
        }
    }

    // if user wants to unbind check if it was the bind owner
    if(!checkBox.on) {
        if(spaceTarget.idUserBindOwner == [[[NSNumberFormatter alloc] init] numberFromString:[Util getIDUser]]) {
            // call the unbind
        }
        else {
            // alert user he cannot do that op
            UIAlertController * alert = [UIAlertController alertControllerWithTitle:[Util getLangValueForTag:@"geofenceUnbindNotAuthorized"]
                                                                            message:@""
                                                                     preferredStyle: UIAlertControllerStyleAlert];

            UIAlertAction *ok = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleCancel handler:^(UIAlertAction *action){}];
            [alert addAction:ok];

            [self presentViewController:alert animated:YES completion:nil];
            [self.tableView reloadData];
        }
    }
    else {

    }
}

Waiting for your replay.

Thanks in advance, Samuel

I'm using this with Carthage (not by choice) and it seems like the Framework Carthage generates doesn't have the Group header file. I'm not sure what the issue is, maybe it needs some configuration updates in the Framework's Xcode project?

So I'm creating a questionnaire app in which I have a UITableView with a custom Cell class that inherits from UITableViewCell, and it contains an additional checkbox attribute on top of the inherited ones. My problem is twofold.

Firstly, for whatever reason, the checkboxes will not render in the XCode interface builder. I'm running the latest versions of Swift and Xcode, and I installed via CocoaPods. Secondly, when the controller starts up some of the checkboxes are selected while others are not. As I scroll, some of them even change. Do you have any ideas as to what might be causing this?

I have migrated everything to Swift (with proper ObjC compat).

Along the way I have solved the main rendering issues - the one where too many layer recreations are performed, and the one where stroke line is bleeding outside of the component.

@Boris-Em I think this will make many people happy. Please take a look.

I'm not sure what you think about this, but I've added some functionality that enables the creation of radio button groups. This allows for the definition of a group of check boxes where only one can be selected at a time, and it can optionally disallow no selections in that group.

If you like the idea I can add some documentation to the README file before merging.

Here's basics on how it works.

Say we have 3 checkboxes that we want to group:

@property (strong, nonatomic) IBOutlet BEMCheckBox *checkBox1;
@property (strong, nonatomic) IBOutlet BEMCheckBox *checkBox2;
@property (strong, nonatomic) IBOutlet BEMCheckBox *checkBox3;

We create a group for the checkboxes:

@property (strong, nonatomic) BEMCheckBoxGroup *group;

Then we add the checkboxes to the group:

- (void)viewDidLoad {
    [super viewDidLoad];

    self.group = [BEMCheckBoxGroup groupWithCheckBoxes:@[self.checkBox1, self.checkBox2, self.checkBox3]];
    self.group.selectedCheckBox = self.checkBox2; // Optionally set which checkbox is pre-selected
    self.group.mustHaveSelection = YES; // Define if there can be no checkboxes selected
}

That's it. You can find out which box is currently selected in the group by asking for it:

BEMCheckBox *selection = self.group.selectedCheckBox;

We can also manually change which box is selected at any time, which will automatically update the other group's box states as well:

self.group.selectedCheckBox = self.checkBox1; // Boxes 2 and 3 will be deselected if one is selected

Of course, the target action and delegate callbacks will all get sent as expected.

Let me know any feedback you have. Hopefully this will be useful.

What is the best scenario for this?

30 checkboxes in 10 tableviewcells, 3 checkboxes in each cell. each defined with tags (a.tag = 101; b.tag = 201; c.tag = 301;) a,b,c are every checkbox has a defined value (how can we achieve this ??) - Example: a.value = @"this is a value"; b.value = [NSDate new]; etc.

Now, i want to get the value tapped on a checkbox when is checked or unchecked (.on event) and to populate the checkboxes with data coming from a json file (matrix of checks?)

Any good idea on how to approach this?

Thanks. Chris

Hi,

I'm using your library and it's truly awesome, congrats =)

I'm suffering a little issue and perhaps you might help me. I've placed an UIView and changed its class to BEMCheckBox afterwards from Storyboard. Everything is running pretty well, but when I try to make an outlet from the BEMCheckBox object in Storyboard to my View Controller I'm getting the next 2 errors:

'weak' may only be applied to class and class-bound protocol types, not '<<error type>>'
Use of undeclared type 'BEMCheckBox'

This is the outlet:

@IBOutlet weak var taskCheckBox: BEMCheckBox!

I'm using Swift and I had to create a bridge. Any idea of what's happening?

If the on value is set without calling reload, the entire checkbox disappears. It is actually still tappable, and would re-appear when it is tapped to on.

Then I tried calling reload after changing on value. This time the checkbox won't disappear, but the on/off animation will be gone forever in this checkbox instance.

If this checbox is a property of a UITableViewCell how do you recieve the delegate method of didTapOn? Perhaps i'm doing this wrong, but i've tried to assign the delegate within my custom tableviewcell and within my cellForRowAtIndexPath inside my tableViewController and still that delegate method does not fire when tapping on the checkbox.

It seems, that BEMPathManager doesn't take into account lineWidth, therefore drawings of the box will be clipped at the bottom by container view and drawings of the checkmark will be slightly skewed downwards

"Platforms" in Package.swift should be updated from iOS v8 to iOS v9 to reflect the minimum supported deployment target version and thus silence a warning when using Swift Package Manager.

Hi, may I propose some enhancement: It would be beneficial to have a delegate function like "shouldChange" with Bool result that gets called just before any state change (selected, unselected) happens triggered form UI. In case the delegate returns false, no change happens and the box stays as it is. Default behaviour: Allow changes. Something similar is available e.g. for UITextField. I have situations, where I need to run checks or calculations before allowing to switch the state. In addition the state sometimes is populated from a popup where multiple entries are required to allow the state become true - clicking on the checkbox with this delegate function would allow me to trigger the popup easily and avoid the user being able to manually check the box. Would keep things simple and avoid having to work with additional gesture recognizers above the box. Regards Oggerschummer

Already updated cocoapods, carthage manager, and podfile and BEMCheckBox dependencies, has anyone faced this before?

Error says the following:
