NSURLSession/NSURLConnection HTTP 加载失败(kCFStreamErrorDomainSSL，-9802) [英] NSURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9802)

问题描述

我收到错误:NSURLSession/NSURLConnection HTTP 加载失败(kCFStreamErrorDomainSSL，-9802)，我怀疑这是因为从 Parse 查询图像.这是我查询的方法:

I am getting the error: NSURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9802), and I suspect that it is because of querying for images from Parse. Here is the method where I am querying:

func fetchImageForEmployee(employee: PFEmployee, completion: (error: String?, image: UIImage?) -> Void) {
    if (employee.profilePicture == nil) {
        completion(error: "No image file", image: nil)
    } else {
        employee.profilePicture!.getDataInBackgroundWithBlock({ (data, error) -> Void in
            if let error = error {
                let errorString = error.userInfo["error"] as? String
                completion(error: errorString, image: nil)
            } else if (data != nil) {
                let image = UIImage(data: data!)
                completion(error: nil, image: image)
            } else {
                completion(error: nil, image: nil)
            }
        })
    }
}

我还打印了错误，这就是调试器中出现的内容:不允许在解除分配时尝试加载视图控制器的视图，并且可能会导致未定义的行为 (UISearchController: 0x13ee44dc0)

I also printed the error, and this is what appeared in the debugger: Attempting to load the view of a view controller while it is deallocating is not allowed and may result in undefined behavior (UISearchController: 0x13ee44dc0)

我不知道出了什么问题，所以感谢所有的答案.

I don't know what is going wrong, so all answers are appreciated.
