iOS packaged app, generate IPA file

If my program is well debugged, how can I send it to others? The IPA file is normally output from Xcode's organizer, but we do not have a certificate so the output generates an error.

Here's how to generate an IPA file:

1. Under your current project--products right-click Show in Finder

2. Go to the Finder to select your project app file, open itunes, drag the current project app into itunes

3. In your itunes app you will see your engineering program, select it, and then drag it out of the itunes list (for example, to the desktop)

4. By This, you will get. IPA! then you can share your program with your friends.
