Question

我在Angular2教程中遇到以下错误。 TNS医生可以，那么为什么会出现以下错误？

'tns livesync ios --emulator --watch

我正在使用新的8x Xcode。

示例 - Groceries项目的Dependences版本很快将更新为最新的NativeScript版本，但是您可以打开package.json文件并更改以下版本：

tns-ios": {"version": "2.3.0"}

"nativescript-angular": "1.0.0"

"tns-core-modules": "2.3.0"。

您还应确保已删除hooks，node_modules，platforms个文件夹。关于这一点，使用Xcode 8，现在某些方法是属性，并且在项目中使用本机代码时将导致问题，就像在样本 - Groceries中一样。作为临时解决方案，您可以替换status-bar-util.ts和grocery-list.component.ts文件中的一些代码。

应用/共享/状态栏-util.ts

UIApplication.sharedApplication().statusBarStyle = UIStatusBarStyle.LightContent;替换为UIApplication.sharedApplication.statusBarStyle = UIStatusBarStyle.LightContent;

应用/杂货/杂货列表/杂货list.component.ts

cell.backgroundColor = UIColor.clearColor();替换为cell.backgroundColor = UIColor.clearColor;
