Question

Dropbox文档默认解释了身份验证的响应被触发到Appdelegate.m中如何使我自己班级的代表同样开火？

- (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;
}

enter image description here 在信息plist网址类型 - ＆gt;在url方案中只需添加db-YourAppKey即可调用此方法。

此方法将自动调用。我希望你已经从dropbox开发者网站创建了app并获得了appKey和appSecret。在app delegate NSString * appKey = @“”;
中使用此代码

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;
        }

//使用此后，打开的URL会自动调用。

这些方法只在AppDelegate.m中响应，你不能在它之外使用它。要在ViewController或任何类中使用，您应该使用帖子后通知

- (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;
}

然后在您的课程中，在ViewController中接收此通知，例如：

- (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

    }
}
