相册选择头像或者拍照 上传头像以NSData 图片二进制格式 表单上传

一、点击头像图片 或者按钮 在相册选择照片返回img，网络上传头像要用data表单上传

(1)上传头像属性

// 图片二进制格式 表单上传
@property (nonatomic, strong) NSData *imageWithData;

（2）头像点击事件

- (void)headImageEvent{
    NSLog(@"上传头像");
    [self selectPhotoAlbumWithSelectPhotoHandle:^(UIImage *img) {
        self.headerImageView.image = img;
        NSData *dataWithImage;
        dataWithImage = UIImageJPEGRepresentation(img, 0.3);
        self.imageWithData = dataWithImage;
    }];

}

（3）打开相册或者拍照

/**
 弹出提示框 选择相机或者相册

 @param selectPhotoHandle 选中或拍摄的图片
 */
- (void)selectPhotoAlbumWithSelectPhotoHandle:(void (^)(UIImage *))selectPhotoHandle{
    self.selectPhotoHandle = selectPhotoHandle;

    UIAlertController *av = [UIAlertController alertControllerWithTitle:nil message:nil preferredStyle:UIAlertControllerStyleActionSheet];
    UIAlertAction *action1 = [UIAlertAction actionWithTitle:@"拍照" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
        [self takePhoto];
    }];
    UIAlertAction *action2 = [UIAlertAction actionWithTitle:@"从手机相册选择" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
        [self LocalPhoto];
    }];
    UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:nil];
    [av addAction:action1];
    [av addAction:action2];
    [av addAction:cancelAction];
    [self presentViewController:av animated:YES completion:nil];
}

//开始拍照
-(void)takePhoto
{
    UIImagePickerControllerSourceType sourceType = UIImagePickerControllerSourceTypeCamera;
    if ([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeCamera])
    {
        UIImagePickerController *picker = [[UIImagePickerController alloc] init];
        picker.delegate = self;
        //设置拍照后的图片可被编辑
        picker.allowsEditing = YES;
        picker.sourceType = sourceType;
        [self presentViewController:picker animated:YES completion:nil];
    }else{
        NSLog(@"模拟其中无法打开照相机,请在真机中使用");
    }
}

//打开本地相册
-(void)LocalPhoto{
    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    picker.delegate = self;
    //设置选择后的图片可被编辑
    picker.allowsEditing = YES;
    [self presentViewController:picker animated:YES completion:nil];
}

//当选择一张图片后进入这里
-(void)imagePickerController:(UIImagePickerController*)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{
    UIImage* image = [info objectForKey:@"UIImagePickerControllerEditedImage"];
    if (self.selectPhotoHandle) {
        self.selectPhotoHandle(image);
    }
    [picker dismissViewControllerAnimated:YES completion:nil];

}

（4）网络上传头像

- (void)postUserHeaderImage
{
    NSMutableDictionary *parameter = [[NSMutableDictionary alloc]init];
    [parameter setValue:userToken forKey:@"userId"];
    [parameter setValue:self.nickeNameTextField.text forKey:@"nickName"];

    [[[NetRequest alloc]init]postRequestWithAPINameForData:@"/robot/userController/updateRecord.do" parameters:parameter imageWithData:self.imageWithData imageWithNameFile:@"portrait" NetRequestProgress:nil NetRequestSuccess:^(NSInteger code, NSString *msg, id response) {

        ShowMessage(@"编辑资料成功");
    } NetRequestFaile:^(NSInteger code, NSString *msg, id response) {
        ShowMessage(@"获取网络数据失败");
    }];
}

（5）上传头像方法

// 以流文件方式上传图片（表单上传）
- (void)postRequestWithAPINameForData:(NSString *)api parameters:(NSDictionary *)param imageWithData:(NSData *)fileData imageWithNameFile:(NSString *)nameFile NetRequestProgress:(NetRequestProgress)progress NetRequestSuccess:(NetRequestSuccess)sucess NetRequestFaile:(NetRequestFaile)faile
{
    // 请求地址
    NSString *urlString = [NSString stringWithFormat:@"%@/%@", baseUrl, api];

    // 设置状态栏网络访问的风火轮
    [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:YES];

    // 网络请求Session
    AFHTTPSessionManager* session = [AFHTTPSessionManager manager];
    session.requestSerializer.timeoutInterval = .f;
    session.responseSerializer.acceptableContentTypes = [session.responseSerializer.acceptableContentTypes setByAddingObject:@"text/html"];
    //    session.responseSerializer = [AFHTTPResponseSerializer serializer];
    // 参数初始化
    NSMutableDictionary *dicParam;
    if (param) {
        dicParam = [NSMutableDictionary dictionaryWithDictionary:param];
    } else {
        dicParam = [NSMutableDictionary dictionary];
    }
//    [dicParam setObject:@"i" forKey:@"p"];      // 平台
//    [dicParam setObject:@"1.0.0" forKey:@"v"];   // 版本

    [session POST:urlString parameters:dicParam constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {

        if (fileData.length > ) {
            NSTimeInterval time = [[NSDate date] timeIntervalSince1970];
            // 注意 img 是后台给的流文件名  一定对应接口否则上传失败
            [formData appendPartWithFileData:fileData name:nameFile fileName:[NSString stringWithFormat:@"%ld.jpg",(unsigned long)time] mimeType:@"image/jpeg"];

        }

    } progress:^(NSProgress * _Nonnull uploadProgress) {
        if (progress) {
            progress(uploadProgress);
        }
    } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        // 取消设置状态栏风火轮
        [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO];

        // API返回结果
        NSInteger nCode = [[responseObject objectForKey:@"status"] integerValue];
        NSString *strMsg = [responseObject objectForKey:@"msg"];
//        id res = [responseObject objectForKey:@"data"];

        if (sucess) {
            sucess(nCode,strMsg,responseObject);
        }
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        // 取消设置状态栏风火轮
        [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO];
        NSString* errResponse = [[NSString alloc] initWithData:(NSData *)error.userInfo[AFNetworkingOperationFailingURLResponseDataErrorKey] encoding:NSUTF8StringEncoding];
        NSLog(@"----%@",errResponse);

        if (faile) {
            faile([@"" intValue],@"网络请求失败\n请检查网络设置",nil);
        }
    }];
}
