问题描述
我正在尝试将Facebook登录信息集成到我的解析应用程序中.我遵循了解析教程中提到的每个步骤.在下面的代码中，出现编译错误.
I'm trying to integrate facebook login in my parse application. I followed every step mentioned in parse tutorial. In the below code, I'm getting compilation error.
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
line1: Parse.setApplicationId("xxx", clientKey: "yyy")
line2: PFFacebookUtils.initializeFacebookWithApplicationLaunchOptions(launchOptions)
line3: PFAnalytics.trackAppOpenedWithLaunchOptions(launchOptions)
line4: return true
}
在第3行中，我收到了错误消息:
In line 3, I'm getting error:
如果我使用'!'手动解开包装，因为launchOptions可以为nil，我得到:
If I manually unwrap it using '!', because launchOptions can be nil, I get:
如果我检查是否为零，我得到:
If I check for nil, I get:
有什么想法要解决吗?
推荐答案
这是ParseSDK中的错误.在解析此问题之前，您可以在PFFacebookUtils.h头文件中更改初始化函数声明
It is a bug in ParseSDK. Until Parse fix this you can change the initialize function declaration at PFFacebookUtils.h header file
1)转到PFFacebookUtils.h
1) Go to PFFacebookUtils.h
2)更改:
- (void)初始化FacebookWithApplicationLaunchOptions:(NSDictionary *)launchOptions;
收件人:
- (void)初始化FacebookWithApplicationLaunchOptions:(PF_NULLABLE NSDictionary *)launchOptions;
