FBConnect的handleOpenURL方法未被我的AppDelegate调用 [英] FBConnect's handleOpenURL Method Not Called by my AppDelegate

问题描述

我已经在我的应用程序中实现了FBConnect SDK，并且在模拟器上工作得很好。然后我适当地修改了我的应用程序的.plist文件，并在设备上安装了Facebook时将AppDelegate添加了必要的方法：

   - （BOOL）应用程序：（UIApplication *）应用程序handleOpenURL :( NSURL *）url {
 NSLog（@handleOpenURL方法被调用并发送以下内容：）; 
 NSString * urlString = [NSString stringWithContentsOfURL：（NSURL *）url]; 
 NSLog（@URL String：％@，urlString）; 
 return [[flipsideViewController facebook] handleOpenURL：url]; 
} 
  

从上面的NSLogs和观察我的应用程序返回到前台后授权通过Facebook访问，我推断，FB应用程序正在适当地移交给我的应用程序的控制权。不幸的是，Facebook.m的handleOpenURL：url方法实际上没有像我在AppDelegate中请求一样调用（即，不显示以下NSLogs）。

   - （BOOL）handleOpenURL：（NSURL *）url {
 //如果URL的结构与用于Facebook授权的结构不匹配，则中止。 
 NSLog（@handleOpenURL由SDK处理好！）; 
 if（！[[url absoluteString] hasPrefix：[self getOwnBaseUrl]]）{
 NSLog（@handleOpenURL结构与用于Facebook授权的结构不匹配）。 
 return NO; 
} 
 // ... 
  

因此，我的应用程序的视图控制器（我点击我的Facebook按钮开始）只是返回到屏幕，我放在'fbDidLogin'方法（在我的视图控制器中用于发布到用户的墙上）的代码从来没有被调用模拟器。

我俯视什么？需要什么其他信息来解决这个问题？任何帮助将非常感激，因为我一直在努力一段时间。

重要摘要注：
1.）应用程序在模拟器上运行。
2.）handleOpenURL当我从AppDelegate请求它时，不调用方法。
3.）我没有收到任何错误/警告。
4.）我可以在我的设备上运行DemoApp，我注意到handleOpenURL方法被DemoAppAppDelegate请求时被适当地调用。

谢谢

解决方案

我最终不得不让我的Facebook对象成为一个单身（存储在appDelegate中）。不完全确定为什么这是必要的，因为我没有在多个viewController中使用fb对象。请注意，如果您知道为什么这是必要的。

I have implemented the FBConnect SDK into my app, and it works perfectly on the simulator. I then modified my app's .plist file appropriately, and added the necessary method to my AppDelegate for when Facebook is installed on the device:

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {
NSLog(@"handleOpenURL Method was called and sent the following:");
NSString *urlString = [NSString stringWithContentsOfURL:(NSURL *)url];     
NSLog(@"URL String: %@", urlString);
return [[flipsideViewController facebook] handleOpenURL:url];
}

From the above NSLogs and the observation that my application is returned to the foreground after authorizing access via Facebook, I infer that the FB App is handing off control to my application appropriately. Unfortunately, Facebook.m's "handleOpenURL:url" method does not actually get called as I request in my AppDelegate (i.e. neither of the below NSLogs are displayed).

- (BOOL)handleOpenURL:(NSURL *)url {
// If the URL's structure doesn't match the structure used for Facebook authorization, abort.
NSLog(@"handleOpenURL was handled by SDK. Good!");
if (![[url absoluteString] hasPrefix:[self getOwnBaseUrl]]) {
NSLog(@"handleOpenURL structure doesn't match the structure used for Facebook authorization. Aborting.");
return NO;
}
//...

As a result, my app's view controller (where I clicked my facebook button to begin with) is simply returned to the screen, and the code I placed in the 'fbDidLogin' method (used in my view controller to publish to the user's wall) never gets called as it did in the simulator.

What am I overlooking? What, if any, other information is needed to solve this problem? Any help would be very much appreciated, as I have been struggling with this for a while.

Important Summary Notes: 1.) Application runs as desired on simulator. 2.) handleOpenURL Method not called when I request it from my AppDelegate. 3.) I do not receive any errors/warnings. 4.) I can run the DemoApp on my device, and I notice that the handleOpenURL Method is called appropiately when requested by the 'DemoAppAppDelegate.'

Thanks in Advance!

解决方案

I ended up having to make my facebook object a singleton (stored in the appDelegate). Not completely sure why this was necessary though, as I was not using the fb object in multiple viewControllers. Please comment if you know why this was necessary.
