My app is asking for permission to “Have offline access”, why? It's the weirdest thing. I've done a bit of searching and haven't really found anything that's worked. I've tried using these for scopes:
https://www.googleapis.com/auth/plus.profile.emails.read
https://www.googleapis.com/auth/plus.login
and that didn't seem to help.
Below is a screenshot and some of my code to help you see what's going on:

Thank you
This is from https://stackoverflow.com/questions/32210920/why-is-my-app-asking-for-permission-to-have-offline-access?answertab=oldest#tab-top:
This is normal behavior and occurs when the user has granted
permission already.
Basically, no need to worry about it unless you really don't want that
showing up, in that case, you need to un auth the users old token
before requesting a new one.
I'm not exactly sure how because I haven't done this before, but before you authorize a new token you need to un-authorize the old one.
You'll need to modify the -(void)getUserInfo:(NSString *)token method.
For some reason unknown to me. The email scope pops up with
Have offline access
If you want to remove the have offline access remove the email scope. Personally I think it is miss leading to users that you are asking for email access yet are prompted for offline access. Technically speaking all OAuth2 that returns a refresh token gives offline access so the user should always be told that you are getting offline access but it doesnt.

I already successfully integrated Google+ to my iOS app. But with the latest Apple store updates, the app is not allowed to open the browser to initiate the Google authentication using safari so i tried uiwebview for googleplus authentication and i am getting the access token but i cannot able to get the username and email address of the person logged in.Below i added my source,

How i can get the username and email of person logged in by using the access token which i got above ? Please give any suggestions as i dont get any solution on google.
Thanks for your support
if you want to fetch the whole profile of the google+ user, you can use the below URL
https://www.googleapis.com/plus/v1/people/me/?access_token={YOUR_ACCESS_TOKEN}
Then call the GET method. You will be given by an array containing authorized profile details.
Another method is that, if you want to store the authorized users email, its already present in the field as id_token. It is a base64_encoded data with some fields. If you decode the id yo will get some information about the user.For example in your result you found id_token as
eyJhbGciOiJSUzI1NiIsImtpZCI6ImRhNjYyNWIzNmJjMDlkMzAwMzUzYjI4YTc0MWNlMTc1MjVhNGMzM2IifQ.eyJpc3MiOiJhY2NvdW50cy5nb29nbGUuY29tIiwic3ViIjoiMTE0MjE4NDEwODI0NzM1ODkyMDg0IiwiYXpwIjoiMTY5NzY2MjI4OTY4LWtoNzI1dTFpZWdzNHN1bnFhOThhcHUxMHU4djhhcmFmLmFwcHMuZ29vZ2xldXNlcmNvbnRlbnQuY29tIiwiZW1haWwiOiJhcmp1bkBsaW5rd2FyZS5pbiIsImF0X2hhc2giOiJQVnJxTURpNDViZnVGTm9kTmlsSFlRIiwiZW1haWxfdmVyaWZpZWQiOnRydWUsImF1ZCI6IjE2OTc2NjIyODk2OC1raDcyNXUxaWVnczRzdW5xYTk4YXB1MTB1OHY4YXJhZi5hcHBzLmdvb2dsZXVzZXJjb250ZW50LmNvbSIsImhkIjoibGlua3dhcmUuaW4iLCJpYXQiOjE0Mzc0ODIwNTUsImV4cCI6MTQzNzQ4NTY1NX0.uSMrV8rOz4T4i5MhiCeQueNVGLv4NBLP-gtOcyow8t4BY9qvUO78sG4y0jPhbclPdX1kUZjzMVTeah2nU9fTYyl50dlj5FzWNy7LyM-a1GC2jEwkgWMgHdRPh6l7dqMrjQ9sU1rF-ZaiWfG7C9VJTJ76uEWRiSKKA9EFQtBil3xBtmDH07UMRxkbri2jBwaCPAWgjU8-dTarrxNESrwrO_nptaRzfGeaTyQBIYCAk6_9deXmblPgteER1OHoa65xb1OVK3ZPeZ3_dj9gjlXSyGp2ho5WIFGf2xRvW4XoROpUYqhLvrS3s-YrrZ8J5X5-3mafrs1qDjJYJogctbW7dg
The above id_token contains 2 parts separated by '.'. The first part is thebase64_encoded key and the second part is metadata.
you can decode both the data as
$key=base64_decode(eyJhbGciOiJSUzI1NiIsImtpZCI6ImRhNjYyNWIzNmJjMDlkMzAwMzUzYjI4YTc0MWNlMTc1MjVhNGMzM2IifQ)
will give you the key

will give you the metadata.
while decoding the data ,it will give the result as
{"iss":"accounts.google.com","sub":"114218410824735892084","azp":"169766228968-kh725u1iegs4sunqa98apu10u8v8araf.apps.googleusercontent.com","email":"arjun#linkware.in","at_hash":"PVrqMDi45bfuFNodNilHYQ","email_verified":true,"aud":"169766228968-kh725u1iegs4sunqa98apu10u8v8araf.apps.googleusercontent.com","hd":"linkware.in","iat":1437482055,"exp":1437485655}
Above result you can find the email filed. I hope this will help you.

I feel the the method you are using will not help to get the profile detail.
I suggest to use the proper method which ensures the best results.
Please check this out : https://developers.google.com/+/mobile/ios/
This will surely help you to get required outcome.
Hi I am integrating google plus integration I want to fetch user information who is currently login. I am able to get token after login but I don't know how to get personal information.
I am login step by step as following this is only because I want to get login without open external browser.
Open url link in UIWebView which open login screen in View Did Load.
UIWebView * webView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 320, 460)];
webView.tag=99;
NSString *url = [NSString stringWithFormat:#"https://accounts.google.com/o/oauth2/auth?response_type=code&client_id=%#&redirect_uri=%#&scope=%#&data-requestvisibleactions=%#",[GPPSignIn sharedInstance].clientID,callbakc,scope,visibleactions];
[webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:url]]];
[self.view addSubview:webView];
Get call for token Login
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType{
if ([[[request URL] host] isEqualToString:#"localhost"]) {
// Extract oauth_verifier from URL query
NSString* verifier = nil;
NSArray* urlParams = [[[request URL] query] componentsSeparatedByString:#"&"];
for (NSString* param in urlParams) {
NSArray* keyValue = [param componentsSeparatedByString:#"="];
NSString* key = [keyValue objectAtIndex:0];
if ([key isEqualToString:#"code"]) {
verifier = [keyValue objectAtIndex:1];
NSLog(#"verifier %#",verifier);
break;
}
}
if (verifier) {
NSString *data = [NSString stringWithFormat:#"code=%#&client_id=%#&client_secret=%#&redirect_uri=%#&grant_type=authorization_code", verifier,[GPPSignIn sharedInstance].clientID,secret,callbakc];
NSString *url = [NSString stringWithFormat:#"https://accounts.google.com/o/oauth2/token"];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:url]];
[request setHTTPMethod:#"POST"];
[request setHTTPBody:[data dataUsingEncoding:NSUTF8StringEncoding]];
NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:request delegate:self];
receivedData = [[NSMutableData alloc] init];
} else {
// ERROR!
}
[webView removeFromSuperview];
return NO;
}
and I get the response in did recieve data
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data{
[receivedData appendData:data];
NSLog(#"verifier %#",receivedData);}
Now after token I want to call for fetch user information who is login, Kindly guide me on this how can I achieve this target, this will be great for me.
Thanks.
Currently I am developing an hybrid app which uses webView shouldStartLoadWithRequest: to provide a token for the login. My function works fine for every normal request I make (a click e.g.)
- (BOOL)webView:(UIWebView*)webView shouldStartLoadWithRequest:(NSURLRequest*)request
NSLog([NSString stringWithFormat:#"Loading View: %#",[[request URL] absoluteString]]);
if ([[[request URL] absoluteString] rangeOfString:BASE_URL].location != NSNotFound) {
NSString *token = [[NSUserDefaults standardUserDefaults] stringForKey:kDefaultsKeyLoginToken];
NSString *hash = [[NSUserDefaults standardUserDefaults] stringForKey:kDefaultsKeyLoginHash];
NSString *params = [NSString stringWithFormat:#"mobile=app&user_token=%#&user_hash=%#",token,hash];
if([[request URL] query] == nil) {
[self LoadUrl:[[request URL] absoluteString] withGetParams:params append:NO];
return NO;
}else{
if([[[request URL] absoluteString] rangeOfString:params].location == NSNotFound){
[self LoadUrl:[[request URL] absoluteString] withGetParams:params append:YES];
return NO;
}
}
}
-(void)LoadUrl:(NSString *)url withGetParams:(NSString *)params append:(BOOL)append{
NSString *PreUrl;
if(append == YES) PreUrl = [NSString stringWithFormat:#"%#&%#",url,params];
else PreUrl = [NSString stringWithFormat:#"%#?%#",url,params];
NSURL *nsurl = [NSURL URLWithString: PreUrl];
NSURLRequest *request = [NSURLRequest requestWithURL:nsurl];
[self.WebView loadRequest:request];
}
The Problem I have with this Code is that if I load an Image e.g. it will be detected as "to be hashed-appended" (which is correct, I want every request to have the Auth included) BUT the Image will get loaded in the Webview itself.
My first try (before I switched to this model) was to modify the request parsed. But every change got Ignored....
Has anyone an Idea how I could fix this problem? Is there a way to really modify requests? Or if not, can I at least determine the "target" of the request or forward it?
Thanks for any help
I found a Solution for my Problem. Sublcassing was the right approach but not UIWebView but a own NSURLProtocol.
So what I did:
Create an own Sublcass of NSURLProtocol
#interface MyURL : NSURLProtocol <NSURLConnectionDelegate>
Add some standard handling for HTTP-Connections
#interface MyURL () <NSURLConnectionDelegate>
#property (nonatomic, strong) NSURLConnection *connection;
#property (nonatomic, strong) NSMutableData *mutableData;
#property (nonatomic, strong) NSURLResponse *response;
#end
#implementation MyURL
+ (NSURLRequest *)canonicalRequestForRequest:(NSURLRequest *)request
{
return request;
}
- (void)stopLoading
{
[self.connection cancel];
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
[self.client URLProtocol:self didLoadData:data];
}
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
[self.client URLProtocol:self didFailWithError:error];
self.connection = nil;
}
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{

And now the interesting part - Modifying every request that goes to my server
So first: Check if this Request goes to my Server and determine if my protocol should take care of it
+ (BOOL)canInitWithRequest:(NSURLRequest *)request
{
NSString *token = [[NSUserDefaults standardUserDefaults] stringForKey:kDefaultsKeyLoginToken];
NSString *hash = [[NSUserDefaults standardUserDefaults] stringForKey:kDefaultsKeyLoginHash];
if([NSURLProtocol propertyForKey:#"TokenSet" inRequest:request]) return NO; // We already handled it
if((hash == nil) || (token == nil) ) return NO; // We are not logged in
NSString *params = [NSString stringWithFormat:#"mobile=app&user_token=%#&user_hash=%#",token,hash];
if (([[[request URL] absoluteString] rangeOfString:BASE_URL].location != NSNotFound) && ([[[request URL] absoluteString] rangeOfString:#"/assets/"].location == NSNotFound)){
if([[[request URL] absoluteString] rangeOfString:params].location == NSNotFound){
return YES; // URL does not contain the login token & we're not requesting an asset (js/img/etc.)
}
}
return NO;
}
So if + (BOOL)canInitWithRequest:(NSURLRequest *)request returned yes, I have to handle the request. I already know that it does not contain the login token & hash so I've got to determine if it has to be appended or not. To modify the request in general, I create a MutableCopy of our request, Modify it and set our URLConnection to the request.
- (void)startLoading
{
NSMutableURLRequest *newRequest = [self.request mutableCopy];
NSString *PreURL;
NSString *token = [[NSUserDefaults standardUserDefaults] stringForKey:kDefaultsKeyLoginToken];
NSString *hash = [[NSUserDefaults standardUserDefaults] stringForKey:kDefaultsKeyLoginHash];
NSString *params = [NSString stringWithFormat:#"mobile=app&user_token=%#&user_hash=%#",token,hash];
if([[newRequest URL] query] == nil) {
PreURL = [NSString stringWithFormat:#"%#?%#",[[newRequest URL] absoluteString],params];
}else{
if([[[newRequest URL] absoluteString] rangeOfString:params].location == NSNotFound){
PreURL = [NSString stringWithFormat:#"%#&%#",[[newRequest URL] absoluteString],params];
}
}
NSURL *nsurl = [NSURL URLWithString: PreURL];
[newRequest setURL:nsurl];
[NSURLProtocol setProperty:#"YES" forKey:#"TokenSet" inRequest:newRequest];
self.connection = [NSURLConnection connectionWithRequest:newRequest delegate:self];
}
And to finish it all, we register our URL-Protocol as Protocol in AppDelegate.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[NSURLProtocol registerClass:[MyURL class]];
}
With this Solution I first have the advantage of having my login token in ANY request ANY part of my App sends to my Server. No more worries about this. And I can do cool stuff, like saving resources after loading them the first time or even use Images from my App-Bundle in Webviews...
I hope this helps someone.
I'm posting to a RESTful webservice and receiving a response, this works great if I'm getting back only a few records however there is a threshold where didReceiveData: stops being called (6 records) and it just hangs. (does not matter what records, just the number)
I can't seem to figure out why. I'm getting a status message of 200 application/json in didReceiveResponse: however that's the last I hear from my connection.
From other clients I can get the full data with any number of records so it's related to my NSURLConnection code.

Edit Server was not giving back a valid length after a certain size triggering NSURLResponseUnknownLength which I had mistakenly not logged so I was not getting my "Invalid URL" message in the console.
if (expectedLength == NSURLResponseUnknownLength)
{
NSString *reason = [NSString stringWithFormat:#"Invalid URL"];
SAFE_PERFORM_WITH_ARG(delegate, #selector(dataDownloadFailed:), reason);
[connection cancel];
return;
}
Try this:
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self startImmediately:NO];
[connection scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSRunLoopCommonModes];
[connection start];
Because if you run the connection in the NSDefaultRunLoopMode and there is UITableView scrolling, it will hang the connection delegate.
However your problem is different. Some servers will limit the number of simultaneous connections from a single client. If you are in the case, then the first connections would succeed and the others would hang until previous connections complete.
