ios - 试图找出这次崩溃的原因

Question

我正在检查 crashlytics。跟踪堆栈跟踪并得到他的错误:

HTTPManager.swift line 313
specialized HTTPManager.(createAuthenticationParameters in _F8C28254BDE35F2F2E746C55EB4303F3)() -> [String : AnyObject]

与:

Crashed: com.apple.main-thread
EXC_BREAKPOINT 0x000000010017c690

方法如下:

private func createAuthenticationParameters() -> Dictionary<String, AnyObject> {
    var parameters = [String:AnyObject]()
    if User.sharedInstance.facebookID != nil {
        parameters["facebook_id"] = User.sharedInstance.facebookID!
    } else if User.sharedInstance.email != nil {
        parameters["email"] = User.sharedInstance.email!
    }
    parameters["auth_token"] = User.sharedInstance.authToken!

    return parameters // LINE 313
}

什么可能导致它崩溃？我只是将值放入字典中。任何指示将不胜感激。谢谢

我建议尝试像这样重写您的代码:

private func createAuthenticationParameters() -> [String: Any] {
    var parameters: [String: Any] = [:]
    if let facebookID = User.sharedInstance.facebookID {
        parameters["facebook_id"] = facebookID
    } else if let email = User.sharedInstance.email {
        parameters["email"] = email
    }

    if let token = User.sharedInstance.authToken {
        parameters["auth_token"] = token
    }

    return parameters // LINE 313
}
