I got a problem , How to know the file is accessible ???
For example , the file is writing , but not finish yet. And I check the file again ,
[[NSFileManager defaultManager] fileExistsAtPath:filePath];
It return true ... but the file is not accessible .
How to determine the file is ready ?
EDIT Maybe I'm not telling my problem clearly . I mean if you start transport a video file . before transport finish . the video file is not accessible , but you still can get a part of transporting file.
