iOS 圖片上傳的兩種方式

我們在寫代碼的時候經常會將頭像進行上傳伺服器，上傳頭像圖片我試過兩種方式

一種方式就是使用base64字串上傳圖片，這種形式我個人認為比較適合上傳圖片數量比較少的，比如上傳頭像，上傳圖片數量多的話，速度會慢些

另一種方式是使用二進位流進行上傳圖片，這種方式上傳圖片少或者數量多都沒關係，速度也很快

選擇頭像效果：



程式如下：

ViewController.h

#import <UIKit/UIKit.h>

@interface ViewController : 
UIViewController

@property (weak, 
nonatomic) IBOutlet
UIImageView *headIcon;
- (IBAction)changeIconAction:(UITapGestureRecognizer *)sender;

@end

ViewController.m

#import "ViewController.h"

#import "AFHTTPRequestOperationManager.h"

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


UIImagePickerController *pickerController;

AFHTTPRequestOperationManager *manager;
}

@end

@implementation ViewController

- (void)viewDidLoad {

[super
viewDidLoad];

//初始化頭像控制項

[self
initHeadIcon];

//初始化pickController

[self
createData];
}
- (void)initHeadIcon
{

self.view.backgroundColor = [UIColor
lightGrayColor];

self.headIcon.layer.cornerRadius
= self.headIcon.frame.size.height/2;

self.headIcon.clipsToBounds =
YES;

self.headIcon.layer.borderColor
= [UIColor whiteColor].CGColor;

self.headIcon.layer.borderWidth
= 3;
}
- (void)createData
{

//初始化pickerController

pickerController = [[UIImagePickerController
alloc]init];

pickerController.view.backgroundColor = [UIColor
orangeColor];

pickerController.delegate =
self;

pickerController.allowsEditing =
YES;
}

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

UIActionSheet *actionSheet = [[UIActionSheet
alloc]initWithTitle:@"選擇頭像"
delegate:self
cancelButtonTitle:@"取消"
destructiveButtonTitle:nil
otherButtonTitles:@"拍照",@"相簿",@"圖庫",
nil];

[actionSheet showInView:[UIApplication
sharedApplication].keyWindow];
}

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{

if (buttonIndex == 
0) {//相機

if([UIImagePickerController
isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{

NSLog(@"支援相機");
[self
makePhoto];
}else{

UIAlertView *alert = [[UIAlertView
alloc]initWithTitle:@"提示"
message:@"請在設定-->隱私-->相機，中開啟本應用的相機存取權限。。"
delegate:self
cancelButtonTitle:@"取消"
otherButtonTitles:@"我知道了",
