推荐答案

尝试将Roberto的建议放在代码中：

Trying to put Roberto's suggestion in code:

1）生成唯一的ID（由时间戳/散列/ CFUUIDCreate ...生成）。

1) generate a unique Id (generated by time stamp/ hash / CFUUIDCreate ...) .

CFStringRef uStr =  CFUUIDCreateString(kCFAllocatorDefault,CFUUIDCreate(kCFAllocatorDefault));  
NSString *uniqueId = [[NSString alloc] initWithString:uStr];  

2）使用此唯一名称保存文件。现在保存SQLite DB中的 uniqueId 。

2) save the file in with this unique name. Now save the uniqueId in SQLite DB.

NSString *docsDir = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];  
NSString *filePath = [docsDir sstringByAppendingPathComponent:uniqueId];  
NSFileManager *fManager = [NSFileManager defaultManager];   
if (![fManager fileExistsAtPath:fileDirPath])   
{   
    // save the file   
}

3）为了获得视频，从 uniqueId ，尝试从它构造文件路径， p>

3) In order to get the video, from the uniqueId, try to construct the file path from it as,

NSString *docsDir = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *filePath = [docsDir sstringByAppendingPathComponent:uniqueId];
NSFileManager *fManager = [NSFileManager defaultManager];  
if ([fManager fileExistsAtPath:fileDirPath])   
{   
    // access the file   
}
