Unity3d upload and crop images locally-----iOS platform

Note: Engine version unity4.x

Recent project needs, need to do the user picture, requirements:

1. can upload from local

2. Local cropping

3. Compression control size

4. Implementation of Pc/android/ios on three platforms

I've been doing it for days.

On the Internet for a period of time, someone recommended a plugin, network address forgot to save, directly on the code bar

OpenPhotoController.h:

@interface Openphotocontroller:nsobject<uiapplicationdelegate,uiimagepickercontrollerdelegate, Uiactionsheetdelegate,uinavigationcontrollerdelegate>
{

uiview* _rootview;
uiviewcontroller* _rootcontroller;
@private
ID _popoverviewcontroller;
}
@property (nonatomic, retain) ID Popoverviewcontroller;
@end

OPENPHOTOCONTROLLER.MM:

Calling Methods in Unity

Directly put these two files in the plugins iOS directory, or packaged out Xcode project and then import these two files can also, recommend the first, do version control time is more convenient

[DllImport ("__internal")]
private static extern void Openphoto ();

public void Openphoto (string vname)
{
#if Unity_iphone
Openphoto ();
#endif
}

Note:

Imgdata= uiimagejpegrepresentation (Image2, 0.5); is a compressed file 0.5 is a compression quality

Upload local image section to get it done!
