nsurl

问题 I want to take a url and convert it to a more readable format. For example I have the following link: http://en.wikipedia.org/wiki/S%C3%A1ndor_Font I take away the unnecessary parts and am left with "S%C3%A1ndor_Font" as a NSString . Is there any sort of way to convert this into "Sándor Font" (what it actually should be), without having to type out every single combination of special characters and replacing each part of the string? To demonstrate how I want to use this, I wrote the following

As my application manages two types of subclassed NSdocument (Text as a reader/writer and Image as a reader only), I try to implement a separate "Open Recent" menu for images.

问题 We are trying to add in functionality into our app to allow it to POST a large file approx 50kb to our web service the file itself is a HTML template, however with the code below what we are finding is that the data seems to get cut off when the web service saves it. The web service is currently designed to check the $_POST['html'] variable and write it to a file. Is there a better way to do this and does anyone have any idea why the upload is not complete?

问题 When resolving an NSURL from a security scoped bookmark, if the user has renamed or moved that file or folder, the bookmark will be stale. Apple's document says this regarding staleness: isStale On return, if YES, the bookmark data is stale. Your app should create a new bookmark using the returned URL and use it in place of any stored copies of the existing bookmark. Unfortunately, this rarely works for me. It may work 5% of the time.

问题 I am having a String to Number problem that is taking me days to resolve. So it all started out in my app that involves taking a phone number from the addressbook and making a call. Everything was working fine until I noticed some phone numbers were causing my program to crash. After some time, I finally figured that they were crashing for the phone numbers that had a space in it, which finally made sense because even though it is a phone number I am using NSURL to call "tel://(555) 555 5555"
