在 iOS 上使用 Branch.io 的 applicationDidBecomeActive 崩溃

Question

TL;DR
错误是 url 中的 space 未被编码。将由他们这边的 Branch Guys 修复

我集成了 iOS SDK 并按照指南中的说明完成了通用链接的所有设置。我已正确配置所有内容（或看起来如此），打开 link 将我带到应用程序。然而，这个问题似乎与深度linking 功能无关。

步骤：

1.- 打开应用程序
2.- 返回主屏幕（不要关闭应用程序）
3.- 再次打开应用程序
4.- 崩溃

指定的 URL 有一个不支持的方案。仅支持 HTTP 和 HTTPS URL

线路崩溃是(BNCStrongMatchHelper.m:114):
UIViewController * safController = [[SFSafariViewControllerClass alloc] initWithURL:[NSURL URLWithString:urlString]];

但是此时urlString是一个httpslink.

Answer 1

尝试将此添加到您的 Info.plist 文件中：

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

Answer 2

来自 Branch.io 的 Alex 进行了更新：经过一些调试，我们确定这是由于 urlString 中的 space（从应用程序版本号通过）。删除此 space 解决了崩溃问题。

Branch 端的一个更永久的解决方案也在开发中。
