從NSUserDefault

Question

在檢索從NSUserDefaultNSUrl我已存儲的路徑NSURL爲NSString到NSUserDefault檢索NSURL，我越來越NSURL路徑像"file:///var/mobile/Containers/Data/Application/EB2E7DCD-5B73-4B0B-9BC5-6758AF75C68C/Documents/FinalVideo-958.mov"但視頻是從這個鏈接顯示....上面的路徑是從iPhone設備

始終使用與下面的代碼相同的相對路徑。

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentsDirectory = [paths objectAtIndex:0]; 

NSString *myPathDocs = [documentsDirectory stringByAppendingPathComponent:@"FinalVideo-958.mov"]; 

if ([[NSFileManager defaultManager] fileExistsAtPath:myPathDocs]) 
{ 
    NSLog(@"video file found."); 
}
