Swift:println() 没有在“查看设备日志"中显示任何内容；在“设备"中标签 [英] Swift : println() doesn't show anything into "View Device Logs" in "Devices" tab

问题描述

我正在开发应用程序，当应用程序使用 AdHoc 配置文件运行时，我需要在其中获取设备令牌.因为我无法使用 AdHoc 配置文件进行调试.我需要查看使用 println() 打印设备令牌的登录信息.但是，我没有展示任何东西.

I am developing the application into which I need to get devicetoken when app is running with AdHoc profile. Because I am not able to debug with AdHoc profile. I need to see log into which I print device token with println(). But, I doesn't show anything into it.

推荐答案

最后，我得到了解决方案.我们也可以使用 NSLog() 进入 swift 代码.所以，我们想在那里打印日志，你使用 NSLog() 函数.例子，

Finally, I got solution for it. We can also user NSLog() into swift code. so, where we want to print log there you use NSLog() function. Example ,

 func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
        var deviceTokenOrigin = deviceToken.description.stringByTrimmingCharactersInSet(NSCharacterSet(charactersInString: "<>"))
        var deviceTokenFiltered = deviceTokenOrigin.stringByReplacingOccurrencesOfString(" ", withString: "")
        self.deviceTocken = deviceTokenFiltered
        NSLog("DeviceToken : %@", deviceTokenFiltered)
    }
