问题 Hi I have a whole bunch of .mp3 files I want to use with NSFileManager and store in the documents folder.

问题 Is there an method to get the contents of a folder in a particular order? I'd like an array of file attribute dictionaries (or just file names) ordered by date modified. Right now, I'm doing it this way: get an array with the file names get the attributes of each file store the file's path and modified date in a dictionary with the date as a key Next I have to output the dictionary in date order, but I wondered if there's an easier way? If not, is there a code snippet somewhere which will do

Storing images locally on an iOS device

由 与世无争的帅哥 提交于 2019-11-26 21:33:04
Some iOS photo-related apps store images created with the app somewhere other than the photo library. For example Fat Booth shows a scrolling list of photos created with the app at app start-up. Note these photos are persisted w/o the user explicitly saving them to the photo library. What is the simplest way to save and persist images inside an iOS application? The only persistent stores I'm familiar with are NSUserDefaults and the key chain. However I've never heard of these used to store larger pieces of data such as an image. Now I'm wondering if Core Data is the easiest way. Tommy Devoy

How to overwrite a file with NSFileManager when copying?

由 两盒软妹~` 提交于 2019-11-26 18:03:32
问题 I'm using this method to copy a file: [fileManager copyItemAtPath:sourcePath toPath:targetPath error:&error]; I want to overwrite a file when it exists already. The default behavior of this method is to throw an exception/error "File Exists." when the file exists. There's no option to specify that it should overwrite. So what would be the safest way to do this? Would I first check if the file exists, then delete it, and then attempt to copy? This has the danger that the app or device goes OFF
