Handling Dropbox authentication response - ios

Question

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
}
}
