确实有可能从另一个申请中进口一个文件,如果是一纸空档机,则使用国际交易日志管理人。你们都需要做的是无益的。您的申请清单需要添加支持的文件格式。增编 DidFinshWithLaunchingOptions sent methods to You app in application delegation category in the following manner.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    [self applicationDidFinishLaunching:application];

    if (launchOptions && [launchOptions objectForKey:UIApplicationLaunchOptionsURLKey])
    {
        NSString* path = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];

        NSURL *url=[launchOptions objectForKey:UIApplicationLaunchOptionsURLKey];
        NSString *sourceFilePath=[url path];        
        NSFileManager *fileManager=[NSFileManager defaultManager];
        NSData *fileData=[fileManager contentsAtPath:sourceFilePath];
        NSString *fileName = [NSString stringWithFormat:@"test.pdf"];
        NSString *updatedFilePath = [path stringByAppendingPathComponent:fileName];

        BOOL hasWrittenSuccessfully = [fileData writeToFile:updatedFilePath atomically:TRUE];   
    }

    return YES;
}

You can t fetch documents, you can tell iOS that your app can open PDF/Doc/XLS. Do this by adding supported filetype to you info.plist: http://developer.apple.com/library/ios/#documentation/FileManagement/Conceptual/DocumentInteraction_TopicsForIOS/Articles/RegisteringtheFileTypesYourAppSupports.html#//apple_ref/doc/uid/TP40010411-SW1
