XCode-在文档目录中找不到文件

Question

I am having random error while reading saved photos from document directory in iPhone. I save photos taken from my app to document directory and then read it from there next time when user come back. However, after XCode 6 & base SDK change to 8.1, this document directory path keeps changing. So sometime I found photos and sometime not.

I read few posts online thats says that not Apple differentiate App from Data and that's why this issue coming up. Anyone has any thoughts on this? Any solution?

This is how I save file to document Directory

NSArray *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentDirectory = [path firstObject];
NSString *filePath = [documentDirectory stringByAppendingPathComponent:@"key"];
[image writeToFile:path atomically:YES];

And this is how I read it:

NSArray *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentDirectory = [path firstObject];
NSString *filePath = [documentDirectory stringByAppendingPathComponent:@"key"];
UIImage *cellImage = [[UIImage alloc] initWithContentsOfFile:filePath];
