问题 Assuming both XML plist and JSON are delivered over http, gzipped, which one will be processed faster on an iPhone? 回答1: A co-worker and I did some rudimentary benchmarks recently to test which was faster for an application we were writing. We tested this JSON framework, and the NSXML parser as well as a TreeNode parser we found in an Objective-C book. Here is the note I sent to the other developers on our team: The benchmark tested how each library handled getting the filename and path of

问题 So the regular intro: I am a newbie to objective c, searched everywhere and could not find, so please help... All I want to do is to set my app to get location updates in the background - THAT'S IT. I know that I suppose to add location to UIBackgroundModes in the info.plist file in my project, however I have just NO CLUE where info.plist is. All I see under my project Build Settings under Packaging is info.plist file (with Release and Debug underneath). No presence of UIBackgroundModes

问题 I've been searching several days for a descent answer on how to acquire the list of installed applications on a device running iOS > 5.0 (com.apple.mobile.installation.plist). I've tried codes from different sources and the only almost successful solution I got was with shared URL scheme approach using Daniel Amitay API (http://www.ihasapp.com) - thumbs up for it - great job! But with the URL scheme I wasn't able to get all installed apps on the device cause not all of them have shared URL

iOS: How to save a custom object that is created in an app

由 情到浓时终转凉″ 提交于 2019-12-09 07:05:16
问题 I've been reading up on saving objects, preserving state etc, but I'm still a little confused on the route I should take when saving objects that are created from my app. I have built an app where a user can create a Radio Station with the Genre, name and frequency. Once a user hits save, a "RadioStation" object is created using a custom class and is stored in an NSMutableArray that is placed in the RootViewController. While RadioStation objects can be stored in this array and are displayed

问题 I have the following Info.plist which I am attempting to associate .mybin files with the applcation. However after installing the .mybin files do not have the icon, the description or the association (when viewing with Get Info). I'm completely new to OSX development and I inherited the packaging of the application so I have no idea how to debug problems. The app is packaged to a .app using productbuild if that makes any difference. I have compared my info.plist against several other

问题 I'm learning how to use plist files for storing data in my iPhone app. I've been reading a bunch of the questions about plist and dictionaryWithContentsOfFile on this site, but can't see what I'm doing wrong. The following line returns nil ("The dictionary is null" to the console). NSLog(@"The dictionary is %@",[NSDictionary dictionaryWithContentsOfFile:@"myFile"]); The myFile.plist file is in the resources folder, and contains a few strings: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE

I am very close to implementing this inside a table view controller but I am having a few issues. The main issue is accessing the names and putting it in an array so that it can be
