Ios 未调用上载的文件

我有一个应用程序，我上传一个简单的.csv文件到Dropbox。当我发送这些文件时，它们可以完美地上传，但是没有调用restclientuploadedfile方法。我想用它来向用户显示文件已成功上传。我似乎记得在我运行代码的前几次调用它时，它就停止了，我不明白为什么

以下是一些片段：

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (buttonIndex == 0)       //Cancel
{
}
else if (buttonIndex == 1)      //Send
{
    NSString *docPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
    NSString *CCD = [docPath stringByAppendingPathComponent:@"CCD.csv"];


    if ([[NSFileManager defaultManager] fileExistsAtPath:CCD])
    {
        NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
        NSString *machineName = [defaults objectForKey:@"machineName"];
        NSString *fileTitle = [defaults stringForKey:@"setTitle"];
        NSMutableString *filePath = [NSMutableString string];
        [filePath appendString:docPath];
        [filePath appendString:@"/CCD.csv"];
        NSString *destDir = @"/";
        [SVProgressHUD showWithStatus:[NSString stringWithFormat:@"Sending to %@...", machineName]];
        [[self restClient] uploadFile:fileTitle toPath:destDir
                        withParentRev:nil fromPath:filePath];

    }

} 
}
- (void)restClient:(DBRestClient*)restClient uploadedFile:(NSString*)filePath {
    NSLog(@"File uploaded successfully");
    [SVProgressHUD dismiss];
};

正如我所说，它完美地上传了文件，只是没有调用uploadedFile方法。

试试这种方法

@interface ResultClass_vice : UIViewController<DBRestClientDelegate>
{
DBRestClient *restClient;
}

#pragma mark - DropBox

- (void)didPressLink {
   // [[DBSession sharedSession]unlinkAll];

    if (![[DBSession sharedSession] isLinked]) {
        [[DBSession sharedSession] linkFromController:self];
        // Session must be linked before creating any DBRestClient objects.

        //   nstr
        UIAlertView *al=[[UIAlertView alloc]initWithTitle:@"" message:@"You must have to Login"  delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
        [al show];
        [al release];

    }
}

- (DBRestClient *)restClient {
    if (!restClient) {
        restClient =
        [[DBRestClient alloc] initWithSession:[DBSession sharedSession]];
        restClient.delegate = self;
    }
    return restClient;
}


- (void)restClient:(DBRestClient*)client uploadedFile:(NSString*)destPath
              from:(NSString*)srcPath metadata:(DBMetadata*)metadata {

    //NSLog(@"File uploaded successfully to path: %@", metadata.path);
    UIAlertView *alert = [[[UIAlertView alloc]initWithTitle:@"Success" message:@"Your file is successfully uploaded to Dropbox" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil]retain];
    [alert show];
    [alert release];

}

- (void)restClient:(DBRestClient*)client uploadFileFailedWithError:(NSError*)error {
    NSLog(@"File upload failed with error - %@", error);
}

@接口结果类设备：UIViewController
{
DBRestClient*restClient；
}
#pragma标记-下拉框
-（无效）按链接{
//[[DBSession sharedSession]取消链接]；
如果（！[[DBSession sharedSession]已链接]）{
[[DBSession sharedSession]linkFromController:self]；
//在创建任何DBRestClient对象之前，必须链接会话。
//nstr
UIAlertView*al=[[UIAlertView alloc]initWithTitle:@”“消息：@“您必须登录”委托：nil CancelButtontile:@“确定”其他Buttontiles:nil，nil]；
[艾尔秀]；
[铝释放]；
}
}
-（DBRestClient*）restClient{
如果（！restClient）{
restClient=
[[DBRestClient alloc]initWithSession:[DBSession sharedSession]]；
restClient.delegate=self；
}
返回客户；
}
-（void）restClient:（DBRestClient*）客户端上载文件：（NSString*）destPath
from：（NSString*）srcPath元数据：（DBMetadata*）元数据{
//NSLog（@“文件已成功上载到路径：%@”，metadata.path）；
UIAlertView*alert=[[UIAlertView alloc]initWithTitle:@“成功”消息：@“您的文件已成功上载到Dropbox”委托：自取消按钮：@“确定”其他按钮：无]保留]；
[警报显示]；
[警报发布]；
}
-（void）restClient:（DBRestClient*）客户端上载文件失败witherror:（NSError*）错误{
NSLog（@“文件上载失败，错误-%@”，错误）；
}

如果您有任何问题，请告诉我，因为我已经实现了它。

主要问题是您更改了上载方法参数：

您正在使用：

- (void)restClient:(DBRestClient*)restClient uploadedFile:(NSString*)filePath {
     NSLog(@"File uploaded successfully to path: %@", metadata.path);
}

你应该使用：

- (void)restClient:(DBRestClient*)client uploadedFile:(NSString*)destPath
from:(NSString*)srcPath metadata:(DBMetadata*)metadata {
    NSLog(@"File uploaded successfully to path: %@", metadata.path);
}

如果更改参数的数量，则是在创建一个新函数，因此Dropbox SDK不会调用它

我希望这会有帮助

当代码“[[self-restClient]uploadFile:fileTitle-toPath:destDir-withParentRev:nil-fromPath:filePath]；”执行时，是否检查了“[self-restClient]”的值。是nil吗？好的，我所要做的就是将：字符串更改为srcPath。我的印象是这些名字是可以自由转让的。显然不是！非常感谢。我有：-（void）restClient:（DBRestClient*）客户端上载文件：（NSString*）文件路径from:（NSString*）fromPath元数据：（DBMetadata*）元数据{}，但它不起作用。是你的。哦，是的！我只是粘贴了我的最新代码，并试图给出最好的答案。我认为问题在于名称，而不是参数的数量。也许两者都有！
