iOS 8 SDK: modal UIWebView and camera/image picker

I found that in iOS 8.0.2 iPad does not seem to have that bug but iPhone still does.

However, overriding following in the view controller containing the uiwebview

-(void)dismissViewControllerAnimated:(BOOL)flag completion:(void (^)(void))completion

And checking that there is a presentedViewController seems to work.

But need to check side effects

#import "UiWebViewVC.h"@interface UiWebViewVC ()@property (weak, nonatomic) IBOutlet UIWebView *uiwebview;@end@implementation UiWebViewVC- (void)viewDidLoad{    [super viewDidLoad];    NSURL *url = [NSURL URLWithString:@"http://html5demos.com/file-api-simple"];    NSURLRequest *request = [NSURLRequest requestWithURL:url];    self.uiwebview.scalesPageToFit = YES;    [self.uiwebview loadRequest:request];}-(void)dismissViewControllerAnimated:(BOOL)flag completion:(void (^)(void))completion{    if ( self.presentedViewController)    {        [super dismissViewControllerAnimated:flag completion:completion];    }}@end

I have the same issue on iOS 9. Try to add ivar '_flag' and then override this methods in view controller with UIWebView

#pragma mark - Avoiding iOS bug- (UIViewController *)presentingViewController {    // Avoiding iOS bug. UIWebView with file input doesn't work in modal view controller    if (_flagged) {        return nil;    } else {       return [super presentingViewController];    }}- (void)presentViewController:(UIViewController *)viewControllerToPresent animated:(BOOL)flag completion:(void (^)(void))completion {    // Avoiding iOS bug. UIWebView with file input doesn't work in modal view controller    if ([viewControllerToPresent isKindOfClass:[UIDocumentMenuViewController class]]    ||[viewControllerToPresent isKindOfClass:[UIImagePickerController class]]) {        _flagged = YES;    }    [super presentViewController:viewControllerToPresent animated:flag completion:completion];}- (void)trueDismissViewControllerAnimated:(BOOL)flag completion:(void (^)(void))completion {    // Avoiding iOS bug. UIWebView with file input doesn't work in modal view controller    _flagged = NO;    [self dismissViewControllerAnimated:flag completion:completion];}

This works for me fine

For me I tend to have a custom UINavigationController so that multiple views can share the same logic. So for my workaround (in Swift) here is what I put in my custom NavigationController.

import UIKitclass NavigationController: UINavigationController {    override func didReceiveMemoryWarning() {        super.didReceiveMemoryWarning()        // Dispose of any resources that can be recreated.    }    override func dismissViewControllerAnimated(flag: Bool, completion: (() -> Void)?) {        if let vc = self.presentedViewController {            // don't bother dismissing if the view controller being presented is a doc/image picker            if !vc.isKindOfClass(UIDocumentMenuViewController) || !vc.isKindOfClass(UIImagePickerController) {                super.dismissViewControllerAnimated(flag, completion:completion)            }        }    }    override func viewDidLoad() {        super.viewDidLoad()        // make sure that the navigation controller can't be dismissed        self.view.window?.rootViewController = self    }}

This means that you can have loads of view controllers with webviews and they'll all work with the file upload element.
