ios 为什么我不能安装三个以上的应用程序？

Why can I not install more than three apps?

提问by Lewis Lebentz

I have just started learning how to make iOS apps, and am using the free personal developer account.

我刚刚开始学习如何制作 iOS 应用程序，并且正在使用免费的个人开发者帐户。

I have made four apps so far, but do not seem to be able to install more than three apps. Even if I have three apps installed, and go to update one of the installed apps I receive the following error message in Xcode:

到目前为止我已经制作了四个应用程序，但似乎无法安装三个以上的应用程序。即使我安装了三个应用程序，然后去更新其中一个已安装的应用程序，我也会在 Xcode 中收到以下错误消息：

App installation failed

The maximum number of apps for free development profiles has been reached.

应用安装失败

已达到免费开发配置文件的最大应用程序数量。

From what I have read, each app should be signed for a week, but I've only been coding from a few days.

从我读到的内容来看，每个应用程序都应该签名一周，但我只从几天开始编写代码。

How can I install more apps, or do I have to delete my existing apps from my device?

如何安装更多应用程序，或者是否必须从我的设备中删除现有应用程序？

Just delete the apps that you have installed using the same profilefrom your device. just clean the project by using the command SHIFT+Command+K,Try to run the project again.In my case it worked .No need to pay any fee.I hope it works for you too.

只需从设备中删除使用相同配置文件安装的应用程序即可。只需使用命令SHIFT+Command+K清理项目，尝试再次运行该项目。在我的情况下，它有效。无需支付任何费用。我希望它也适用于您。

Go to Window-> Devices and Simulators. Then deleteany apps from the INSTALLED APPSsection. Just clean and run the project. It worked for me.

转到Window-> Devices and Simulators。然后从已安装的应用程序部分删除任何应用程序。只需清理并运行项目。它对我有用。

For me by removing unnecessary provisioning profiles from the device.

对我来说，通过从设备中删除不必要的配置文件。

1. In the Xcode go to Window → Devices and Simulators.
2. Right click the device you are unable to install app.
3. Delete some provisioning profiles.

1. 在 Xcode 中，转到 Window → Devices and Simulators。
2. 右键单击您无法安装应用程序的设备。
3. 删除一些配置文件。

Clean App and then run will work.

Clean App 然后运行即可。

The actual limitation for the number of applications on a free developer account (at the time of writing) seems to be like this:

免费开发者帐户上的应用程序数量的实际限制（在撰写本文时）似乎是这样的：

• Three usable apps (I mean: 3 apps with an active provisioning profile)

• 三个可用的应用程序（我的意思是：3 个具有活动配置文件的应用程序）

But, probably due to an error the way Apple counts, you can't compile and install directly the third app. You have to remove it from the device before installing.

但是，可能由于 Apple 计算方式的错误，您无法直接编译和安装第三个应用程序。在安装之前，您必须将其从设备中删除。

I believe there was not a satisfactory answer yet...

我相信还没有一个令人满意的答案......

It is a big sudden problem that came with OSX10. There are several errors I and others report:

这是 OSX10 带来的一个大问题。我和其他人报告了几个错误：

on new project:

1/ The maximum number of apps for free development profiles has been reached.

on the project working on macOS before 10 (8 or 9) .

1/ mycode0001 requires a provisioning profile. Select a provisioning profile for the "Debug" build configuration in the project editor.

2/ Code signing is required for product type 'Application' in SDK 'iOS 10.0'

在新项目上：

1/ 已达到免费开发配置文件的最大应用程序数量。

在 10 (8 或 9) 之前在 macOS 上工作的项目。

1/ mycode0001 需要配置文件。在项目编辑器中为“调试”构建配置选择配置文件。

2/ SDK 'iOS 10.0' 中的产品类型 'Application' 需要代码签名

It is critical for quite a few developers to know how to address this!

对于很多开发人员来说，知道如何解决这个问题至关重要！

This is how I solved this issue: I deleted all my test apps in the emulator and on the iPhone. Additionaly, I removed them in iTunes. Afterwards that message disappeared and I was able to build my app.

我是这样解决这个问题的：我删除了模拟器和 iPhone 上的所有测试应用程序。另外，我在 iTunes 中删除了它们。之后该消息消失了，我能够构建我的应用程序。

I just delete one app installed using the same profile, then it works. Besides I change another Apple Develper ID, then it works.

我只是删除了一个使用相同配置文件安装的应用程序，然后它就可以工作了。此外，我更改了另一个 Apple Developer ID，然后它就可以工作了。
