Question

我正在使用Dropbox Core API，当我想发送一个简单的[restClient loadMetadata:@"/"]请求以便测试我的应用时，我既不会收到错误也不会成功回复。我用Charles嗅到了我的流量，看来Dropbox SDK没有发送任何请求。我的应用已关联。我已经复制粘贴了他们提供的代码。在这里。

-(BOOL) application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {

    if ([[DBSession sharedSession] handleOpenURL:url]) {
        if ([[DBSession sharedSession] isLinked]) {
            NSLog(@"App linked successfully!");
// At this point you can start making API calls
            DBRestClient *restClient = [[DBRestClient alloc] initWithSession:[DBSession sharedSession]];
            restClient.delegate = self;

                [restClient loadMetadata:@"/"];       
        }
        return YES;
    }
    // Add whatever other url handling code your app requires here
    return NO;

}

我也在控制台上显示“App linked successfully”。

Dropbox iOS SDK中存在与内存管理相关的错误。以下是我在Dropbox论坛上的帖子的引用：

当DBRestClient实例声明为局部变量时，它   在范围的最后发布。它可能在此之前发生   实际上它完成了执行请求。因此，连接   被取消，我们无法收到回电。为了避免这种情况   DBRestClient在启动任何请求时保持自己   完成后自我释放。

你可以做的是，首先用下面的函数替换你的那个函数（你发布的函数）...（在Appdelegate.m文件中）

   - (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url
{
if ([[DBSession sharedSession] handleOpenURL:url])
{
    if ([[DBSession sharedSession] isLinked])
    {
        NSLog(@"App linked successfully!");
        // At this point you can start making API calls

        NSArray *tmp=[self.navigationController viewControllers];
        for(int i=0;i<[tmp count];i++){
            if([[tmp objectAtIndex:i] isKindOfClass:[YourViewController class]]){//YourViewController is a class in which you want to implement dropbox sdk...
                //[self.navigationController popToViewController:[tmp objectAtIndex:i] animated:YES];
                [[tmp objectAtIndex:i]  uploadToDropBox];
                break;
            }

        }
    }
    return YES;
}
return NO;
}

现在在“YourViewController”类中，您要在dropbox上存在该文件。在该文件（.m文件）中的代码下面写入

  -(void)uploadToDropBox
{
    NSString *strzipname=[NSString stringWithFormat:@"%@_Document.zip",strname];
    NSString *path = [DOCUMENTS_FOLDER stringByAppendingPathComponent:strzipname];
    NSString *destDir = @"/";
     restClient = [[DBRestClient alloc] initWithSession:[DBSession sharedSession]];//DBRestClient *restClient; declare object in .h file
    restClient.delegate = self;

   [restClient uploadFile:strzipname toPath:destDir withParentRev:nil fromPath:path];//strzipname is a file name,"path" is path where that file is located
}

最后实现了dropbox的委托方法......

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

NSLog(@"File uploaded successfully to path: %@", metadata.path);
 }

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

不要忘记在.h文件中声明uploadToDropBox ...

让我知道它的工作与否!!!

快乐编码!!!!
