[置顶] iOS 图片上传使用base64或者二进制流上传头像

我们在写代码的时候经常会将头像进行上传服务器，上传头像图片我试过两种方式

一种方式就是使用base64字符串上传图片，这种形式我个人认为比较适合上传图片数量比较少的，比如上传头像，上传图片数量多的话，速度会慢些

另一种方式是使用二进制流进行上传图片，这种方式上传图片少或者数量多都没关系，速度也很快

选择头像效果：

程序如下：

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController

@property (weak, nonatomic) IBOutletUIImageView *headIcon;

- (IBAction)changeIconAction:(UITapGestureRecognizer *)sender;

@end

ViewController.m

#import "ViewController.h"

#import "AFHTTPRequestOperationManager.h"

@interface ViewController ()<UIImagePickerControllerDelegate,UINavigationControllerDelegate,UIActionSheetDelegate>

{

   UIImagePickerController *pickerController;

    AFHTTPRequestOperationManager *manager;

}

@end
