摘要：
我们直接在m文件的引用头文件部分和@interfaceAddPictureViewController（）之间添加添加部分的代码，然后您可以使用图片传输到Base64#import“AddPictureViewController.h”#import #import #import˂MobileCo
我们直接在.m文件的引用头文件部分 和 @interface AddPictureViewController ()
之间 加入 增加部分的代码
然后就可以使用图片转Base64了
#import "AddPictureViewController.h"
#import <QuartzCore/QuartzCore.h>
#import <QuartzCore/CoreAnimation.h>
#import <MobileCoreServices/UTCoreTypes.h>
