如何将文件上载到Dropbox ios

我正在尝试将文件上载到Dropbox。上传不起作用。上传方法如下所示

//  RootViewController.m

-(NSString *)getDocumentPath{

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *path = [[paths objectAtIndex:0]stringByAppendingPathComponent:FILENAME];
    return path;
}
-(IBAction)download:(id)sender{
    NSLog(@"download pressed");
    [self.activityIndicator startAnimating];
    [self.restClient loadFile:@"/dbTutorial.plist" intoPath:[self getDocumentPath]];

}
-(IBAction)upload:(id)sender{

    NSLog(@"upload pressed");
    [self.activityIndicator startAnimating];
    NSString *path = [self getDocumentPath];
    [self.itemArray writeToFile:path atomically:YES];
    [self.itemArray uploadFile:FILENAME toPath:@"/" fromPath:path];// When I build this is the warning that I get:NSMutableArray may not respond to -uploadFiletoPath:fromPath


}

多谢各位。任何帮助都将不胜感激。

应该如此

[self.restClient上载文件：文件名toPath:@“/”fromPath:path]；

我试过上面的代码，效果很好………

你能告诉我如何跟踪上传进度吗？我检查了-（void）restClient:（DBRestClient*）客户端上载进度：（CGFloat）progress for file:（NSString*）destPath from:（NSString*）srcPath；但是不知道怎么用这个。。。

- (void)uploadPhoto
{

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *path = [[paths objectAtIndex:0]stringByAppendingPathComponent:@"Kallol.jpg"];

    NSString *pathString = @"/Photos";

    [self.restClient uploadFile:@"Kallol12.jpg" toPath:pathString fromPath:path];

}
