handleOpenURL not called after linking to Dropbox - iOS - ios

I have started exploring the Dropbox API for an app that I have where I would like the user to be able to back up the database file. The problem I have run into is that after the user links the app with their account (similar to logging in via Facebook) the app doesn't return to the foreground. When I manually go back to the app it is still on the backups screen, but the account has not been linked (as best as I can tell) and the handleOpenUrl app delegate method is not called.
Any ideas? or maybe someone knows a good tutorial for this. The sample Dropbox app works fine, and I'm doing my best to use it as a guide but obviously i've messed something up.
App Delegate:
#import "AppDelegate_iPad.h"
#import <DropboxSDK/DropboxSDK.h>
#interface AppDelegate_iPad () <DBSessionDelegate>
#end
#implementation AppDelegate_iPad
#synthesize window,viewController;
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.viewController = [[mainMenuViewController alloc]init];
[window addSubview:viewController.view]; //< this is a main menu viewcontroller for my app
[self.window makeKeyAndVisible];
// Set these variables before launching the app
NSString* appKey = #"XXXX";
NSString* appSecret = #"XXX";
NSString *root = kDBRootAppFolder;
NSString* errorMsg = nil;
if ([appKey rangeOfCharacterFromSet:[[NSCharacterSet alphanumericCharacterSet] invertedSet]].location != NSNotFound) {
errorMsg = #"Make sure you set the app key correctly in DBRouletteAppDelegate.m";
} else if ([appSecret rangeOfCharacterFromSet:[[NSCharacterSet alphanumericCharacterSet] invertedSet]].location != NSNotFound) {
errorMsg = #"Make sure you set the app secret correctly in DBRouletteAppDelegate.m";
} else if ([root length] == 0) {
errorMsg = #"Set your root to use either App Folder of full Dropbox";
} else {
NSString *plistPath = [[NSBundle mainBundle] pathForResource:#"Info" ofType:#"plist"];
NSData *plistData = [NSData dataWithContentsOfFile:plistPath];
NSDictionary *loadedPlist =
[NSPropertyListSerialization
propertyListFromData:plistData mutabilityOption:0 format:NULL errorDescription:NULL];
NSString *scheme = [[[[loadedPlist objectForKey:#"CFBundleURLTypes"] objectAtIndex:0] objectForKey:#"CFBundleURLSchemes"] objectAtIndex:0];
if ([scheme isEqual:#"db-APP_KEY"]) {
errorMsg = #"Set your URL scheme correctly in DBRoulette-Info.plist";
}
}
DBSession* session =
[[DBSession alloc] initWithAppKey:appKey appSecret:appSecret root:root];
session.delegate = self; // DBSessionDelegate methods allow you to handle re-authenticating
[DBSession setSharedSession:session];
[session release];
if (errorMsg != nil) {
[[[[UIAlertView alloc]
initWithTitle:#"Error Configuring Session" message:errorMsg
delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil]
autorelease]
show];
}
NSURL *launchURL = [launchOptions objectForKey:UIApplicationLaunchOptionsURLKey];
NSInteger majorVersion =
[[[[[UIDevice currentDevice] systemVersion] componentsSeparatedByString:#"."] objectAtIndex:0] integerValue];
if (launchURL && majorVersion < 4) {
// Pre-iOS 4.0 won't call application:handleOpenURL; this code is only needed if you support
// iOS versions 3.2 or below
[self application:application handleOpenURL:launchURL];
return NO;
}
return YES;
}
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url { /// this is never called
if ([[DBSession sharedSession] handleOpenURL:url]) {
if ([[DBSession sharedSession] isLinked]) {
NSLog(#"App linked successfully!");
// At this point you can start making API calls
}
return YES;
}
return NO;
}
#end
From the main Menu, the user pressed a backup button and that opens the following view controller:
#import "BackupManagerViewController.h"
#import <DropboxSDK/DropboxSDK.h>
#import <stdlib.h>
#interface BackupManagerViewController () <DBRestClientDelegate>
//#property (nonatomic, readonly) DBRestClient* restClient;
#end
#implementation BackupManagerViewController
#synthesize itemsArray,delegate;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
#pragma mark - View lifecycle
- (void)viewDidLoad
{
//[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
}
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)orientation
{
return (orientation != UIDeviceOrientationLandscapeLeft) &&
(orientation != UIDeviceOrientationLandscapeRight);
}
- (IBAction)didPressLink {
if (![[DBSession sharedSession] isLinked]) {
[[DBSession sharedSession] link];
} else {
[[DBSession sharedSession] unlinkAll];
[[[[UIAlertView alloc]
initWithTitle:#"Account Unlinked!" message:#"Your dropbox account has been unlinked"
delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil]
autorelease]
show];
}
}
-(DBRestClient *)restClient{
if (restClient == nil) {
restClient = [[DBRestClient alloc]initWithSession:[DBSession sharedSession]];
restClient.delegate = self;
}
return restClient;
}
-(IBAction) closeButtonPressed {
[delegate closeBackupManager];
}
#end

Things to check are
Make sure you don't have two applications with same db-APP_KEY
Make sure only one of these is implemented (not both) in your application delegate.
(a)
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
(b)
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url
Option (b) is deprecated so please go with the option (a) in your new applications
You have entered correct APP_KEY in the URL scheme .

I ran into the same problem, but got it working after deleting the sample app DBRoulette from the simulator. I also deleted my own app and restarted the simulator, but I am not sure if those steps were necessary.

Did you add the drop box URL schema to your app's info.plist?

I believe this problem had to do with running in the simulator. I ran it on a device and it worked fine.

Crash when EZRecorder calls ExtAudioFileWrite on iPhone X

I have a sample app that uses AudioKit to record audio and display a waveform of that audio data. This sample app has two viewControllers with the root vc being a blank page with a button that will take the user to the audio recording page.
For some reason, only on iPhone X (iOS 11.4.1), while recording audio, if I hit the back button on the navigation bar (top left) and then try to go and record again the app will crash.
Specifically the app appears to crash when the recorder's method appendDataFromBufferList: withBufferSize: calls ExtAudioFileWrite(self.info->extAudioFileRef, bufferSize, bufferList). The error message that is printed in the console is:
testAudioCrash(1312,0x16e203000) malloc: * **error for object 0x109803a00: incorrect checksum for freed object - object was probably modified after being freed.
* **set a breakpoint in malloc_error_break to debug
I've gone through zombie profiling, leak profiling, stepped through the logic and the stack but I can't seem to figure out why this is happening.
Below i've provided the code for the test app as well as screenshots of the stack and the console output. Any help with figuring out why this is crashing would be greatly appreciated. Unfortunately the fact that this crash is also not 100% reproducible makes it a little more obscure to me.
Notes for code below:
There is no custom code in the .h files so I have not provided that. There are xib files for each view controller with the UI components for this. They're pretty simple so I have not provided information on those as well though I have no problem in providing any information on them, that anyone requests. I can also zip up the project and share that if anyone feels it's necessary.
Repro steps:
1) launch app
2) tap on record Audio button
3) tap on record button
4) hit back button on navigation bar
5) repeat steps 2-4 until crash happens

Azure AD B2C getting oauthConnection Error: Bad Request

While trying to integrate Azure AD B2C, I am stuck with an error "oauthConnection Error: Bad Request". Following their given sample app it all works fine. But after integrating the same copy paste code from the working sample app, and trying to log in with Facebook or Google Plus, it throws an error! I am pretty sure that every credential that I used in the sample app is the same for my app. Any idea about this will be highly appreciated. Here is my code, AppDelegate.m

Google + sign in within app

I want to integrate Google+ sign in functionality to my app. I have used Google+ sdk , but it redirect to safari to sign in to google , I want to open that web dialog within my application. Can anybody help me on that thing?
I did it. By inheriting UIApplication class and then handling url in web view. Here is code:
Add Google+ FrameWork to your project.
Now, on authentication call, catch that URL by inhereting UIAPPLICATION Class.
- (IBAction)btnGooglePlusTap:(id)sender
{
[[GPPSignIn sharedInstance] authenticate];
}
SubClassUIApplication.h
#import <UIKit/UIKit.h>
#define ApplicationOpenGoogleAuthNotification #"GoogleFriendInvitationPosted"
#interface SubClassUIApplication : UIApplication
#end
#import "SubClassUIApplication.h"
#implementation SubClassUIApplication
- (BOOL)openURL:(NSURL *)url
{
if([[url absoluteString] hasPrefix:#"googlechrome-x-callback:"])
{
return NO;//This will prevent call to Google Chrome App if installed.
}
else if([[url absoluteString] hasPrefix:#"https://accounts.google.com/o/oauth2/auth"])
{
[[NSNotificationCenter defaultCenter] postNotificationName:ApplicationOpenGoogleAuthNotification object:url];
return NO;// Here we will pass URL to notification and from notification observer , we will load web view.
}
else if ([[url absoluteString] hasPrefix:#"com.google"])
{
return NO;
}
return [super openURL:url];
}
#end
Set this subclass as principal class in info.plist file.
Now open URL to web view
- (void)catchNotificationforGooglePlusSharing:(NSNotification *)notiofication
{
NSURL *u=(NSURL *)notiofication.object;
UINavigationController *navWebView =(UINavigationController *) [self.storyboard instantiateViewControllerWithIdentifier:#"WebViewNavController"];
WebViewController *vcWebView = navWebView.viewControllers[0];
vcWebView.webURL = u;
[self.navigationController presentViewController:navWebView animated:YES completion:Nil];
}
Now in webviewcontroller.m
- (void)viewDidLoad
{
[super viewDidLoad];
NSURLRequest *req= [[NSURLRequest alloc]initWithURL:webURL];
[webvGoogle loadRequest:req];
}
#pragma mark - UIWebViewDelegate method
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
BOOL canHandle = [GPPURLHandler handleURL:request.URL sourceApplication:#"com.apple.mobilesafari" annotation:nil];
if(canHandle == YES)
{
[self dismissViewControllerAnimated:YES completion:^
{
}];
}
return YES;
}
- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error
{
NSLog(#"Error in loading : %#",error.description);
}
Don't forget to register your class for ApplicationOpenGoogleAuthNotification notification.
You can use GTMOAuth2ViewControllerTouch from Google Toolbox for Mac - OAuth 2 Controllers.
#import <GTMOAuth2ViewControllerTouch.h>
GTMOAuth2ViewControllerTouch *googleAuthViewController = [[GTMOAuth2ViewControllerTouch alloc]
initWithScope:#"https://www.googleapis.com/auth/userinfo#email"
clientID:kClientId
clientSecret:kSecretId
keychainItemName:#"GooglePlus_Sample_App"
delegate:self
finishedSelector:#selector(viewController:finishedWithAuth:error:)];
[self.navigationController pushViewController:googleAuthViewController animated:YES];

how to ask permissions for email again if its permission is denied in authoriztion on facebook login into iOS app

In my app,there is facebook login am creating custom ui for facebook login.I am fetching users public profile and email.On first time logining in with facebook there is an authorization screen shown as shown in 1.jpg.In this screen there is a option to user which displays edit the info you provide.On clicking that edit button user is directed to next screen where he can deny access for email.My issue is if there is a provision that edit the info you provide button is hidden or is there any possibilty that user is asked for email permission again.

Try this. Hope it helps

Handling Dropbox authentication response

Dropbox documentation explains by default the response for authentication gets fired into Appdelegate.m
How do I make the same fire my own class's delegate?
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url
sourceApplication:(NSString *)source annotation:(id)annotation {
if ([[DBSession sharedSession] handleOpenURL:url]) {
if ([[DBSession sharedSession] isLinked]) {
NSLog(#"App linked successfully!");
// At this point you can start making API calls
}
return YES;
}
// Add whatever other url handling code your app requires here
return NO;
}
In info plist url type --> in url schemes just add db-YourAppKey this method will get called.
This method is getting called automatically. I hope you already created app from dropbox developer site and get the appKey and appSecret. Use this code in app delegate NSString* appKey = #"";
NSString* appSecret = #"";
NSString *root = kDBRootDropbox;
NSString* errorMsg = nil;
if ([appKey rangeOfCharacterFromSet:[[NSCharacterSet alphanumericCharacterSet] invertedSet]].location != NSNotFound) {
errorMsg = #"Make sure you set the app key correctly in DBRouletteAppDelegate.m";
} else if ([appSecret rangeOfCharacterFromSet:[[NSCharacterSet alphanumericCharacterSet] invertedSet]].location != NSNotFound) {
errorMsg = #"Make sure you set the app secret correctly in DBRouletteAppDelegate.m";
} else if ([root length] == 0) {
errorMsg = #"Set your root to use either App Folder of full Dropbox";
} else {
NSString *plistPath = [[NSBundle mainBundle] pathForResource:#"Info" ofType:#"plist"];
NSData *plistData = [NSData dataWithContentsOfFile:plistPath];
NSDictionary *loadedPlist =
[NSPropertyListSerialization
propertyListFromData:plistData mutabilityOption:0 format:NULL errorDescription:NULL];
NSString *scheme = [[[[loadedPlist objectForKey:#"CFBundleURLTypes"] objectAtIndex:0] objectForKey:#"CFBundleURLSchemes"] objectAtIndex:0];
if ([scheme isEqual:#"db-APP_KEY"]) {
errorMsg = #"Set your URL scheme correctly in DBRoulette-Info.plist";
}
}
DBSession* session =
[[DBSession alloc] initWithAppKey:appKey appSecret:appSecret root:root];
session.delegate = self; // DBSessionDelegate methods allow you to handle re-authenticating
[DBSession setSharedSession:session];
[DBRequest setNetworkRequestDelegate:self];
// [[DBSession sharedSession]unlinkAll];
if ([[DBSession sharedSession] isLinked])
{
isAccountForDropBox = YES;
}
else{
isAccountForDropBox = NO;
}
//After using this that open url will get call automatically.
These method only respond in AppDelegate.m,you can't use outside it.
To use in your ViewController or any class, you should use post notification
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url
sourceApplication:(NSString *)source annotation:(id)annotation {
if ([[DBSession sharedSession] handleOpenURL:url]) {
if ([[DBSession sharedSession] isLinked]) {
NSLog(#"App linked successfully!");
// Post Notify here
[[NSNotificationCenter defaultCenter] postNotificationName:#"applicationDidLinkWithDropbox" object:self];
}
return YES;
}
// Add whatever other url handling code your app requires here
return NO;
}
Then receive this notification in your class, in a ViewController for example:
- (void)viewDidLoad
{
[super viewDidLoad];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(dropBoxDidLink:)
name:#"applicationDidLinkWithDropbox"
object:nil];
}
- (void) dropBoxDidLink:(NSNotification *)notification {
if ([[notification name] isEqualToString:#"applicationDidLinkWithDropbox"]) {
//Handle your task here
}
}
