我在使用 Alamofire 时遇到 HTTP 请求问题。当我尝试使用 XCode 调试器重现问题时，它不会崩溃，但是当我存档应用程序并在装有 ios 10.0.2 的 iPad 上运行 .ipa 文件时，我总是会崩溃。
这是一个在运行归档应用程序时崩溃的调用示例:
static func loginOnServerUrl(serverURL: String, user: String, password: String,
successCallback: ((JSON) -> Void)? = nil, failureCallback: ((Error) -> Void)? = nil){
let params = [
ApiParams.ACTION : "login",
ApiParams.LoginParams.USER : user,
ApiParams.LoginParams.PASSWORD : password,
]
Alamofire.request("http://\(serverURL)/AppSrv", method: .get, parameters: params).responseJSON { response in
switch response.result {
case .success(let value):
//JSON raiz
let json = JSON(value)
for (key, value) in json.acceptingSigleValueAsArray {
log("\(key) : \(value)")
}
if let successCallback = successCallback {
successCallback(json)
}
case .failure(let error):
log(error.localizedDescription)
if let failureCallback = failureCallback {
failureCallback(error)
}
}
}
}
这是我收到的崩溃日志之一:

最佳答案
将 Swift 编译器优化级别更改为
Fast, Single File Optimization
而不是整个模块!
整个模块优化和 Alamofire 似乎有些不寻常!
关于ios - Alamofire 仅在运行存档应用程序时崩溃，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/40177652/
