iPhone：无法启动模拟应用程序：未知错误 [英] iPhone: Failed to launch simulated application: Unknown error

问题描述

这是一个新的iPhone项目，只有一个目标（不同于这个问题）

This is a new iPhone project, only 1 target (different from this question)

在构建中我们得到：

Failed to launch simulated application: Unknown error.

谷歌再一次给了我们什么，很多人都遇到过这个，并且有很多疯狂的想法尝试哦清理构建，清除缓存，扭动这个标志，它们都不能正常工作和工作。我们可以使用SDK 2.2.1和3.0 beta在两台不同的机器上重现这一点。不是在机器上安装，因为其他iphone项目工作正常，所以我们认为它与这个特定项目的配置有关，但在梳理了两次配置后我们无法发现问题。

The google again gives us nothing, lots of people have encountered this and there are lots of crazy ideas to try "oh clean the build", "clear the cache", "twiddle this flag" and none of them work and work consistently. We can reproduce this on two different machines with SDK 2.2.1 and 3.0 beta. Not the install on the machines since other iphone projects work just fine so we believe it has something to do with the config of this particular project but after combing through the config twice we can't spot the problem.

Vanna，我想以200美元的价格买一条线索。

Vanna, I'd like to buy a clue for $200 please.

• 试过：XCode菜单 - >清除缓存


• 尝试：清理所有目标


• 尝试：rm -rf~ / Library / Application \ Support / iPhone \ Simulator

推荐答案

更改产品名称对我有用。我尝试了几种不同的选择，所有这些都很好。这是我在开始时使用的魔术产品名称，每次我回到它时都会失败。 YMMV。

Changing the product name worked for me. I tried several different alternatives and all of them worked fine. It was the "magic product name" I used at the onset that failed every time I went back to it. YMMV.
