如何刪除存儲在文檔文件夾中的視頻？

Question

我已將視頻存儲在文檔文件夾中。路徑是

/Users/sridhar/Library/Application Support/iPhone Simulator/User/Applications/EC177E77-8665-485C-93DE-62350FA6D0E7/Documents/air.mp4 

我想刪除視頻。我怎樣才能以編程方式做到這一點。

它應該工作：

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentsDirectory = [paths objectAtIndex:0]; 
NSString *filePath = [documentsDirectory stringByAppendingPathComponent:@"air.mp4"]; 
BOOL succeed = [[NSFileManager defaultManager] removeItemAtPath:filePath error:nil];
