当我测试这个的时候，它就工作了。我不明白它怎么会崩溃

还有一点很奇怪，@objc-goToNext方法，因为我声明它时没有@objc

有人知道的更多吗

编辑：

我测试了回调是否通过

if NSThread.isMainThread() { print("Main Thread") }

因此，取消hud不会是问题。

尝试取消主线程上的SVProgressHUD.disclose（），因为您现在正在后台取消它，hud交互通常必须在主线程中完成

 dispatch_async(dispatch_get_main_queue {
    SVProgressHUD.dismiss()
 })

我猜您的回调发生在视图控制器内存不足之后

无论何时进行异步调用，都应该将self转换为弱self

 SVProgressHUD.show()
    let selectedRow = self.pickerView.selectedRowInComponent(0)
    let profileId = self.profiles[selectedRow].id
    RemoteServiceFactory.serviceCall().updateUser(profileId) { [weak self] (result, error) in

        SVProgressHUD.dismiss()
        guard let weakSelf = self else { return }

        if error != nil {
            weakSelf.showErrorWithMessage("error")
        } else {
            weakSelf.goToNextStep(weakSelf[selectedRow])
        }
    }

我猜@objc是隐含的，因为您的类继承自NSObject。坠机报告中有没有提示原因的信息…无效地址或其他什么？没有，我看不出来。我真的不明白。如果没有选择任何内容，该方法可能会崩溃？如果RemoteServiceFactory.serviceCall（）是对后端服务的调用，那么它的completionHandler实际上不在主线程上，而是它是异步方法回调在线程1上，所以它在主线程上。我认为这不是问题，对吗？我建议你试试这个。。。我也犯了同样的错误，这个问题真的解决了吗？因为我用if-NSThread.isMainThread（）{print（“Main Thread”）}测试了我是否在主线程上。有时它不会让您知道…只是尝试一下

 SVProgressHUD.show()
    let selectedRow = self.pickerView.selectedRowInComponent(0)
    let profileId = self.profiles[selectedRow].id
    RemoteServiceFactory.serviceCall().updateUser(profileId) { [weak self] (result, error) in

        SVProgressHUD.dismiss()
        guard let weakSelf = self else { return }

        if error != nil {
            weakSelf.showErrorWithMessage("error")
        } else {
            weakSelf.goToNextStep(weakSelf[selectedRow])
        }
    }
