Cordova Camera Plugin Takes Forever to Fire

Cordova Camera Picker Takes a Long Time to Load. Fast and Easy Fix.

While trying to fire the camera plugin on cordova i realized the action was taking forever to fire about 30-40 seconds. I saw a bug on console and immediately started doing research. I found a useful stackoverflow, but it was not as clear so i decided to leave a clear written example of how it should be fixed. 

1. Locate Plugins/CDVCamera.m

2. Locate showCameraPicker

3. You need to include the top code into the dispatch_async

4. Here is how the function should look. 

- (void)showCameraPicker:(NSString*)callbackId withOptions:(CDVPictureOptions *) pictureOptions
{
    // CDVCameraPicker* cameraPicker = [CDVCameraPicker createFromPictureOptions:pictureOptions];
    // self.pickerController = cameraPicker;

    // cameraPicker.delegate = self;
    // cameraPicker.callbackId = callbackId;
    // // we need to capture this state for memory warnings that dealloc this object
    // cameraPicker.webView = self.webView;

    // Perform UI operations on the main thread
    dispatch_async(dispatch_get_main_queue(), ^{

        CDVCameraPicker* cameraPicker = [CDVCameraPicker createFromPictureOptions:pictureOptions];
        self.pickerController = cameraPicker;

        cameraPicker.delegate = self;
        cameraPicker.callbackId = callbackId;
        // we need to capture this state for memory warnings that dealloc this object
        cameraPicker.webView = self.webView;

        
        // If a popover is already open, close it; we only want one at a time.
        if (([[self pickerController] pickerPopoverController] != nil) && [[[self pickerController] pickerPopoverController] isPopoverVisible]) {
            [[[self pickerController] pickerPopoverController] dismissPopoverAnimated:YES];
            [[[self pickerController] pickerPopoverController] setDelegate:nil];
            [[self pickerController] setPickerPopoverController:nil];
        }

        if ([self popoverSupported] && (pictureOptions.sourceType != UIImagePickerControllerSourceTypeCamera)) {
            if (cameraPicker.pickerPopoverController == nil) {
                cameraPicker.pickerPopoverController = [[NSClassFromString(@"UIPopoverController") alloc] initWithContentViewController:cameraPicker];
            }
            [self displayPopover:pictureOptions.popoverOptions];
            self.hasPendingOperation = NO;
        } else {
            cameraPicker.modalPresentationStyle = UIModalPresentationCurrentContext;
            [self.viewController presentViewController:cameraPicker animated:YES completion:^{
                self.hasPendingOperation = NO;
            }];
        }
    });
}
