使用Box api- Objective-c iOS将文件上传到特定文件夹

#import <BoxContentSDK/BoxContentSDK.h>

// 首先进行身份验证
NSString *APIKey = @"YOUR_API_KEY";
NSString *accessToken = @"YOUR_ACCESS_TOKEN";

BoxSDK *sdk = [BoxSDK sharedSDK];
BoxOAuth2Session *session = [[BoxOAuth2Session alloc] initWithClientID:APIKey
                                                          accessToken:accessToken
                                                       refreshToken:nil
                                                             tokenExpiration:nil];
[sdk.authSession setOAuth2Session:session];

// 创建文件上传请求
NSString *filePath = @"PATH_TO_YOUR_FILE";
NSString *folderID = @"TARGET_FOLDER_ID";

BoxFilesRequestBuilder *builder = [[BoxFilesRequestBuilder alloc] init];
builder.name = [filePath lastPathComponent];
builder.parentID = folderID;

BoxFilesResourceManager *filesManager = [sdk.filesResourceManager];
BoxFilesRequest *request = [filesManager uploadFileRequestToFolderWithID:folderID
                                                              fromLocalFilePath:filePath
                                                                     requestBuilder:builder];

// 发送上传请求
[request performRequestWithProgress:^(long long totalBytesTransferred, long long totalBytesExpectedToTransfer) {
    // 上传进度回调
    float progress = (float)totalBytesTransferred / (float)totalBytesExpectedToTransfer;
    NSLog(@"上传进度：%f", progress);
} completion:^(BoxFile *file, NSError *error) {
    // 上传完成回调
    if (error) {
        NSLog(@"上传失败：%@", error.localizedDescription);
    } else {
        NSLog(@"上传成功！");
    }
}];
