Here I give an example of how to export a file to iPhone documents folder programmatically. I spent a lot of time on managing of how to do it. My main problem was that I couldn’t find documents folder of iPhone simulator. I couldn’t write anything to file and I used a wrong way with NSData class. Finally, I found a recipe in Internet and modified it a little bit.<\/p>\n
So look at the example:<\/p>\n
This is just a method. Firstly, we discover a documents Directory<\/strong> of a device. Then we NSLog<\/strong> it in order to find that directory on Mac, if we use iPhone\/iPad simulator. Then we make a file name to write the data to using the documents directory. Then create content – four lines of text, including even some non ASCII<\/strong> text(that’ the modification). Then we just save content to the documents directory. Now that file is available through iTunes in programs tab<\/strong>, in the bottom of it for the given Applicaton. Note that you should add “Application supports iTunes file sharing”<\/strong> line and check it in your Info.plist file for your application in order to be able to use iTunes\/iPhone\/Programs\/Your app to share files. Also note that encoding:NSUTF8StringEncoding<\/strong> is needed if you want to use non ASCII letters.<\/p>\n Here I give an example of how to export a file to iPhone documents folder programmatically.
