Unity-iOS-MemoryCheck

A simple Unity 3D Plugin that allows C# code to call a static C function to obtain the available disk space on iOS.

Instructions - XCode

• Clone or download the project (Built using XCode 7.2)
• Run the project
• CTRL-Click the libMemoryViewIOS.a file under /Products and select 'Show in Finder'
• Copy the compiled .a file and place it in Assets/Plugins/iOS under your Unity project

Instructions - Unity

• Browse to the file in your Project explorer
• In the Inspector, ensure that only iOS is selected, and click apply
• Wherever you want to use the methods, add the internal flag and call the methods

For example, in the global variable scope of a class:

#if UNITY_IPHONE
    [DllImport("__Internal")]
    public static extern double CheckFreeSpace();
#endif

... and then from within a method scope:

#if UNITY_IPHONE
    double space = CheckFreeSpace();
    print("Unity found " + space + " free space");
#endif

Features

Currently the Plugin only has one method - CheckFreeSpace(), which returns a double (calculated to megabytes) of how much available space the iOS device has. Other methods may be added in the future, such as general file tree utilities - feel free to open an issue if one is requested.
