Could not signal service com.apple.WebKit.WebContent: 113: Could not find specified service
I'm getting this message regularly in iOS when I try to load HTML in WKWebView. Also it's repeating when I open a WKWebView page.
WKWebViewConfiguration *conf = [[WKWebViewConfiguration alloc] init];
_articleWebView = [[WKWebView alloc] initWithFrame:_mainView.containterViiew.bounds configuration:conf];
_articleWebView.navigationDelegate = self;
_articleWebView.scrollView.scrollEnabled = NO;
[_mainView.containterViiew addSubview:_articleWebView];
[_articleWebView loadHTMLString:_articleDesc.pageContent baseURL:nil];
Also I'm trying to get the content height of the WKWebView in finish method. When the above error occurs, I am getting different height values.
- (void)webView:(WKWebView *)webView didFinishNavigation:(null_unspecified WKNavigation *)navigation {
[webView evaluateJavaScript:#"document.readyState"
completionHandler:^(id complete, NSError * _Nullable error) {
if (complete != nil) {
NSString *javascriptString = #"var body = document.body;var html = document.documentElement;Math.max(html.offsetHeight);";
[webView evaluateJavaScript:javascriptString
completionHandler:^(id _Nullable result, NSError * _Nullable error) {
if (!error) {
NSNumber *height = result;
NSLog(#"height ----------->>>%#", height);
});
}
}];
}
Situation
I am trying to change an Objective-C project from Parse to firebase. What I am trying to do is replacing Parse codes with corresponding firebase code. This strategy worked for my login page and login was successful
The login page calls a segue to MainViewController. The MainViewController loads but the app crashes with an error
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Cannot do a comparison query for type: (null)'
What I Did
This is the firebase code I added in LoginViewController - (IBAction)loginButtonClicked:(id)sender
//Checking for username and password
_emailId=_emailTextField.text;
_password=_passwordTextField.text;
//reference for firebase
self.ref = [[FIRDatabase database] reference];
if([self isInternet])
{
//firebase authentication
[[FIRAuth auth]signInWithEmail:_emailId password:_password completion:^(FIRUser *user, NSError *error) {
// ...
if (error) {
//login failed
[self failsLoginWithError:#"Please try again later"];
}
else
{
NSLog(#"Login Successful");
[self successLoginWithResposne:user];
}
and this is the parse code I commented out
PFQuery *query=[PFQuery queryWithClassName:#"normal"];
[query whereKey:#"usermail" equalTo:_emailId];
[query whereKey:#"password" equalTo:_password];
[query whereKey:#"user_removed" equalTo:#(0)];
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (error) {
//login failed
[self failsLoginWithError:#"Please try again later"];
}
if ([objects count]==0) {
NSLog(#"Invalid username or passowrd");
[self failsLoginWithError:#"Invalid email or password"];
} else {
PFObject *obj = [objects firstObject];
ud = [NSUserDefaults standardUserDefaults];
BOOL isBlocked = [[obj valueForKey:#"blocked"] boolValue];
BOOL isLogged = [[obj valueForKey:#"logged"]boolValue];
NSString *userID = [ud objectForKey:#"ObjectID"];
if (isLogged) {
if ([userID isEqualToString:obj.objectId]) {
if (isBlocked) {
[self failsLoginWithError:#"Login Blocked! Please contact your Doctor"];
}else{
// Login success
[self successLoginWithResposne:obj];
}
}
else{
// login Failed
[obj setValue:#(1) forKey:#"blocked"];
[obj saveInBackground];
[self failsLoginWithError:#"Login Blocked! Please contact your Doctor"];
}
}
else {
// login success
[obj setValue:#(1) forKey:#"logged"];
[obj saveInBackground];
[self successLoginWithResposne:obj];
}
}
} ];
The error message says "exception due to comparison with a null value".
Guess this is due to some parse code somewhere comparing a value that is received from the LoginViewController (which I commented out).
Question
How to fix this?
How do I find the part where the comparison is happening?
Do I have to replace every parse code with firebase code before executing?
if so, How to find every parse code in the project?
Crash report:
Exact line where code crashes:
You may look for the User system parse has build in
Example
[PFUser logInWithUsernameInBackground:_emailId password:_password
block:^(PFUser *user, NSError *error) {
if (user) {
if(user[#"blocked"] == #YES){
return [PFUser logOut];
}else{
// USER AUTHENTICATED
}
} else {
// Password, Conection
}
}];
All local store will be available by using this anywhare in your app:
PFUser *currentUser = [PFUser currentUser];
if (currentUser) {
// do stuff with the user
} else {
// show the signup or login screen
}
If you want to auth with the email insted of a "username" just use the username as the email in registration.
I am using facebook SDK , and when I am trying to invite friend via facbook by using fb invite deep linking.
NSDictionary * getParam = #{
#"access_token":accessToken,
#"fields":#"canonical_url",
#"pretty":#(YES),
};
NSString * getCanoicalURL = [NSString stringWithFormat:#"%#/%#",FB_CANONICAL_API, fbAPILinkID];
[self GET:getCanoicalURL parameters:getParam success:^(NSURLSessionDataTask * _Nonnull task, id _Nonnull responseObject)
{
NSError *error;
FacebookLink * getResult = [MTLJSONAdapter modelOfClass:[FacebookLink class] fromJSONDictionary:responseObject error:&error];
if (error)
{
handler(nil,error);
}
else
{
handler(getResult.canonicalUrl,nil);
}
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error)
{
handler(nil,error);
}];
The below is my invite friend method it show successfully :
-(void)inviteFriend:(NSString*)canonicalUrl
{
FBSDKAppInviteContent *content =[[FBSDKAppInviteContent alloc] init];
content.appLinkURL =[NSURL URLWithString:canonicalUrl];
[FBSDKAppInviteDialog showFromViewController:self withContent:content delegate:self];
}
But when I try to fetch for defer deep link it always null:
FBSDKAppLinkUtility fetchDeferredAppLink:^(NSURL *url, NSError *error)
{
NSLog(#"fetch defer app link :%#",url);
if (error) {
NSLog(#"Received error while fetching deferred app link %#", error);
}
if (url) {
[[UIApplication sharedApplication] openURL:url];
}
}];

I have run into an issue on iOS 8 with the Assets Library framework that appears to be a bug in iOS 8. If I create an album called 'MyMedia' and then delete it, then when I try to create the album again, this chunk of code below returns 'nil' indicating that the album 'MyMedia' exists even though it does not because I deleted it using the 'Photos' app.
__block ALAssetsGroup *myGroup = nil;
__block BOOL addAssetDone = false;
NSString *albumName = #"MyMedia";
[assetsLib addAssetsGroupAlbumWithName:albumName
resultBlock:^(ALAssetsGroup *group) {
myGroup = group;
addAssetDone = true;
} failureBlock:^(NSError *error) {
NSLog( #"failed to create album: %#", albumName);
addAssetDone = true;
}];
while (!addAssetDone) {
[[NSRunLoop currentRunLoop] runUntilDate:[NSDate dateWithTimeIntervalSinceNow:0.05f]];
}
return myGroup; // returns nil if group has previously been created and then deleted
This same method works when creating a brand new album 'MyMedia2.' Has anyone else experienced this issue and know of a workaround or solution? Is the only solution to move to the new 'Photos' framework or am I doing something incorrect here? Note that this code always works on iOS7.X
Actually the steps to reproduce this problem are as follows ->
1. Uninstall your app that takes photos and saves them to a custom album
2. Under iOS Photos delete the custom album that has saved photos in it
3. Install your app
4. If you take pictures or record videos with the app it does not create them or store them. If you look under iOS Photos albums the custom album one does not exist and none of the pictures/videos taken with the app exist.
My previous answer was incorrect. I had not really tested it out. I did finally figure out what had to be done and it was difficult but I got it to work. This is what I had to do to get my app to run on both iOS 7.x.X and iOS 8.X.x and create a custom album that had been previously deleted by the app -->
I wrote two chunks of code: one that uses the Photos framework on iOS 8.x.x and one that uses the AssetsLibrary framework on iOS 7.x.x
Sp the app could run on both iOS versions, I linked the app to the Photos framework but then changed it from required to optional so it would not be loaded on iOS 7.x.x
Because the Photos framework code could not be called directly at runtime on iOS 7.x.x, I had to change it so it loaded the classes, functions (and blocks!) dynamically at runtime
Here is the code chunk that works when running on an iPhone. This should work in the simulator too -->
// PHPhotoLibrary_class will only be non-nil on iOS 8.x.x
Class PHPhotoLibrary_class = NSClassFromString(#"PHPhotoLibrary");
if (PHPhotoLibrary_class) {
/**

[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
[PHAssetCollectionChangeRequest creationRequestForAssetCollectionWithTitle:title];

if (!success) {

}];

Using Adam's answer, and Marin Todorov's Category on ALAssetsLibrary, ALAssetsLibrary+CustomPhotoAlbum to create photo Albums, and place photos in them, this code below replaces the main workHorse in that Category, it works on both iOS7 devices and iOS 8.1 devices for those who need to have both.
it gives two warnings about performSelector on unknown class though, any improvements are appreciated:
(it will not copy a photo from a shared album that you did not create and will fail with message, any enhancements there also would be good)
1) add the "Photos" Frameworks, set to "optional"
2) include the import line #import < Photos/PHPhotoLibrary.h >

Just wanted to update everyone I should have updated sooner but I got kind of swamped with work. This issue is/was an issue with iOS 8 but has been fixed with iOS 8.0.2 so all you need to do to fix it is update your iOS to iOS 8.0.2
I used the below code to check whether a specific album exists, and if it does not exist, create it and add a couple of images to it. After creating an Asset from a UIImage, I use its placeholder to add it to the album without leaving the block.
//Will enter only in iOS 8+
Class PHPhotoLibrary_class = NSClassFromString(#"PHPhotoLibrary");
if (PHPhotoLibrary_class)
{
[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^
{
//Checks for App Photo Album and creates it if it doesn't exist
PHFetchOptions *fetchOptions = [PHFetchOptions new];
fetchOptions.predicate = [NSPredicate predicateWithFormat:#"title == %#", kAppAlbumName];
PHFetchResult *fetchResult = [PHAssetCollection fetchAssetCollectionsWithType:PHAssetCollectionTypeAlbum subtype:PHAssetCollectionSubtypeAlbumRegular options:fetchOptions];
if (fetchResult.count == 0)
{
//Create Album
PHAssetCollectionChangeRequest *albumRequest = [PHAssetCollectionChangeRequest creationRequestForAssetCollectionWithTitle:kAppAlbumName];
//Add default photos to it
NSMutableArray *photoAssets = [[NSMutableArray alloc] init];
for (UIImage *image in albumDefaultImages)
{
PHAssetChangeRequest *imageRequest = [PHAssetChangeRequest creationRequestForAssetFromImage:image];
[photoAssets addObject:imageRequest.placeholderForCreatedAsset];
}
[albumRequest addAssets:photoAssets];
}
}
completionHandler:^(BOOL success, NSError *error)
{
NSLog(#"Log here...");
}];
}
As none of the above suggestions helped me, this is how I went about solving the issues with saving assets (photos) to a custom album name.
This code: "fetchCollectionResult.count==0" specifically handles the situation when you have deleted your custom album once and trying to save to it again, as I suppose fetchCollectionResult might stop being 'nil'.
You can easily change this to support saving of videos/movies too.
This code is for iOS 8 only!
You must make sure not to call it if the device is running on earlier versions!
#define PHOTO_ALBUM_NAME #"MyPhotoAlbum"
NSString* existingAlbumIdentifier = nil;
-(void)saveAssetToAlbum:(UIImage*)myPhoto
{
PHPhotoLibrary* photoLib = [PHPhotoLibrary sharedPhotoLibrary];
__block NSString* albumIdentifier = existingAlbumIdentifier;
__block PHAssetCollectionChangeRequest* collectionRequest;
[photoLib performChanges:^
{
PHFetchResult* fetchCollectionResult;
if ( albumIdentifier )
fetchCollectionResult = [PHAssetCollection fetchAssetCollectionsWithLocalIdentifiers:#[albumIdentifier] options:nil];
// Create a new album
if ( !fetchCollectionResult || fetchCollectionResult.count==0 )
{
NSLog(#"Creating a new album.");
collectionRequest = [PHAssetCollectionChangeRequest creationRequestForAssetCollectionWithTitle:PHOTO_ALBUM_NAME];
albumIdentifier = collectionRequest.placeholderForCreatedAssetCollection.localIdentifier;
}
// Use existing album
else
{
NSLog(#"Fetching existing album, of #%d albums found.", fetchCollectionResult.count);
PHAssetCollection* exisitingCollection = fetchCollectionResult.firstObject;
collectionRequest = [PHAssetCollectionChangeRequest changeRequestForAssetCollection:exisitingCollection];
}
NSLog(#"Album local identifier = %#", albumIdentifier);
PHAssetChangeRequest* createAssetRequest;
createAssetRequest = [PHAssetChangeRequest creationRequestForAssetFromImage:myPhoto];

I have recently started using Facebook SDK 3.1, and am encountering some problems with logging in using openActiveSessionWithReadPermissions.
Actually, loggin in works perfectly, if there is a cached token available, it logs in without presenting Facebook UI, and if not, it presents the UI.
The problem occurs after I make a call to reauthorizeWithPublishPermissions. If I call reauthorizeWithPublishPermissions, then close and reopen the application, and make a call to openActiveSessionWithReadPermissions, it presents the Facebook UI and requires the user to say "yes I'm OK with read permissions", even though there is a cached token available.
It only presents the Facebook UI erroneously if I make a call to reauthorizeWithPublishPermissions, otherwise everything works fine.
Open for read code:
[FBSession openActiveSessionWithReadPermissions:readpermissions allowLoginUI:YES
completionHandler:^(FBSession *aSession, FBSessionState status, NSError *error) {
[self sessionStateChanged:[FBSession activeSession] state:status error:error];
if (status != FBSessionStateOpenTokenExtended) {
// and here we make sure to update our UX according to the new session state
FBRequest *me = [[FBRequest alloc] initWithSession:aSession
graphPath:#"me"];
[me startWithCompletionHandler:^(FBRequestConnection *connection,
NSDictionary<FBGraphUser> *aUser,
NSError *error) {
self.user = aUser;
aCompletionBlock(aSession, status, error);
}];
}
}];
the sessionStateChanged function:
- (void)sessionStateChanged:(FBSession *)aSession state:(FBSessionState)state error:(NSError *)error {
if (aSession.isOpen) {
// Initiate a Facebook instance and properties
if (nil == self.facebook || state == FBSessionStateOpenTokenExtended) {
self.facebook = [[Facebook alloc]
initWithAppId:FBSession.activeSession.appID
andDelegate:nil];
// Store the Facebook session information
self.facebook.accessToken = FBSession.activeSession.accessToken;
self.facebook.expirationDate = FBSession.activeSession.expirationDate;
}
} else {
// Clear out the Facebook instance
if (state == FBSessionStateClosedLoginFailed) {
[FBSession.activeSession closeAndClearTokenInformation];
}
self.facebook = nil;
}
}
the Publish call, with an empty aPublishAction for testing:
- (void)doPublishAction:(void(^)(FBSession *aSession, NSError *error))aPublishAction {
if ([FBSession.activeSession.permissions
indexOfObject:#"publish_actions"] == NSNotFound) {
NSArray *writepermissions = [[NSArray alloc] initWithObjects:
#"publish_stream",
#"publish_actions",
nil];
[[FBSession activeSession]reauthorizeWithPublishPermissions:writepermissions defaultAudience:FBSessionDefaultAudienceFriends completionHandler:^(FBSession *aSession, NSError *error){
if (error) {
NSLog(#"Error on public permissions: %#", error);
}
else {
aPublishAction(aSession, error);
}
}];
}
else {
// If permissions present, publish the story
aPublishAction(FBSession.activeSession, nil);
}
}
Thanks for everything in advance, I would be grateful for any and all help!!
You need to add
[FBSession.activeSession handleDidBecomeActive];
to your -(void) applicationDidBecomeActive:(UIApplication *)application method in your app's delegate as stated in the migration guide.
What if you use openActiveSessionWithPermissions instead of openActiveSessionWithReadPermissions?
