XCode 5.x + Maverick crashes on File operations

由 你说的曾经没有我的故事 提交于 2019-12-07 01:57:05
问题 after updating my OS to Maverick, Xcode 5.01 started to crash every time a "file operation" is attempted. With file operation I mean any operation that requires a file picker window to appear (e.g.: distribute an .ipa, add a file to the project, open a new project, etc) with a delay wich goes from seconds to split seconds. The error is always the same: Process: Xcode [2802] Path: /Applications/Xcode.app/Contents/MacOS/Xcode Identifier: com.apple.dt.Xcode Version: 5.0.1 (3335.23) Build Info:

override getter only needs @synthesize

由 自古美人都是妖i 提交于 2019-12-07 01:09:23
问题 I want to ovveride getter for lazy instantiation and leave default setter. Do I need @synthesize ? Why ? @interface Foo() @property (strong, nonatomic) NSObject *bar; @end @implementation Foo - (NSObject *)bar { if(!_bar) _bar = [[NSObject alloc] init]; return _bar; } @end Update: I've changed variable and class name, because it was confusing. From Deck and card to Foo and bar. 回答1: No, you only need to explicitly synthesize (to get the synthesized ivar) if you explicitly implement all of the

Springboard failed to launch application with error 3, 0, 4, etc

由 谁都会走 提交于 2019-12-06 18:33:17
问题 Why Xcode fails to launch application in simulator? I've gone through many solutions on the web but sometimes they work and sometimes they don't. Many times what I did to solve the problem is quitting the simulator, deleting the application, resetting content settings of simulator, and clean and build. But why should I try anyone (all) of these each time. Xcode is eating the development time in by having all these bugs. And even sometimes it gives lost connection, app quit unexpectedly errors

Use iOS 5 Simulator in XCode 5?

由 若如初见. 提交于 2019-12-06 16:49:11
问题 It seems that XCode 5 only comes with the iOS 6 and 7 simulators. Is there a way to use the iOS 5 simulator with XCode 5? 回答1: If you're using Xcode 5 under OS X v10.8 then if you go to Preferences -> Downloads you should see the 5.0 and 5.1 simulators available under 'Components'. You can download and install directly from there. If you're using Xcode 5 under OS X v10.9 then the iOS 5 simulator is no longer available. In terms of lessons to learn, Apple did exactly the same thing with iOS 4

Insert test data in Core Data

由 无人久伴 提交于 2019-12-06 16:21:38
I'm currently writing some unit tests in a project using Core Data (Xcode 5). For testing purpose I need to insert a bundle of data into my Core Data model in the setUp . What is the easiest way doing that? For instance it would be helpful if I could write an XML file and populate this into my Core Data . You can use Valentina studio to open Core Data Model(SQLite file) and insert values. I end up inserting the test data programatically in the test setup. You can check this article for a guide for testing Core Data - to sum it up, they are using MagicalRecord: http://www.cimgf.com/2012/05/15

问题 I have a parse database with a class named MeetingObject filled with 6000 objects (it will grow by the way...). Being the parse query limit 1000 I'm trying to get them using the skip query property.
