如何确定，在我们的设备中的iPhone应用程序（previous /下一个版本）是否存在与否？ [英] How to determine, whether an iphone app (previous/next version) is existed in our device or not?
问题描述
- 我有2个版本.... iPaint1 （
FreeVersion的）及应用程序; iPaint2 （付费版的）
iPaint 2与iPaint1 ..
的功能以及额外功能- 如果用户有iPaint1＆放大器;此外，如果他安装Paint2。
现在我们需要显示警报，当用户启动/使用paint2。警报会弹出如下
你已经在这第二版paint1的所有功能，删除Paint1自由空间
，否则没有必要警觉，这怎么可能。
（我想我们可以利用AppStore的ID和放大器实现这一本，捆绑标识符，但不知道和不知道的进程）
在此先感谢

- I Have an app with 2 versions.... iPaint1 (
FreeVersion) & iPaint2(Paid Version)iPaint 2 has extra features along with the features of iPaint1..
- if user have iPaint1 & also if he installed Paint2.
Now we need to display An alert when user launch/uses paint2. Alert will be pop up as
"You already have all features of paint1 in this 2nd version, Delete Paint1 to free space"only if iPain1 is existed in our device, otherwise no need of alert How is it possible.
(I guess we may achieve this this using AppStore ID & Bundle Identifier but not sure and don't know the process)

Your best alternative may to be use of custom URL schemes. With these you can implement a link in your free app that opens the paid one if it is installed.
