Why can't I save files to my iOS apps /Documents directory?
Tag : ios , By : Marianisho

I wish this help you Here you have an example of saving the image: assuming you get the content of the image into NSData object: NSData *pngData = UIImagePNGRepresentation(image);
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsPath = [paths objectAtIndex:0]; //Get the docs directory
NSString *filePath = [documentsPath stringByAppendingPathComponent:@"image.png"]; //Add the file name
[pngData writeToFile:filePath atomically:YES]; //Write the file

Listing files from specific documents directory folder

around this issue Don't try to get to the documents directory that way. It won't work. Use this code fragment instead:
NSString *docsPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];

iOS 8 - Share Documents Directory Between Apps
Date : March 29 2020, 07:55 AM
Any of those help No, you cannot have a shared documents directory, but you can have a shared folder in which you can use as your documents directory. When you create an app group Create an identifier for each of your apps in the app group.Then you can use the file manager to get the URL for the directory you want with the given group identifier. let url = NSFileManager.defaultManager().containerURLForSecurityApplicationGroupIdentifier("group.com.MTC.DataSender")!
