由 淺唱寂寞╮ 提交于 2019-11-26 12:19:28
问题 I\'ve been referencing a lot of Projects, and i do it through adding their paths in Header Search Paths. I\'ve been following the referencing stuffs through the \"Referenced Project\'s\" getting Started (like for example including the ZXingWidget) . And I\'ve been doing it a lot now, but I don\'t understand the checking of recursive. What does this mean? When do I check a path for \"recursive?\" Thanks 回答1: If you give Xcode a path to use for headers, it will check that path when you use an

How to visually create and use static cells in a UITableView embedded in a UIViewController

由 感情迁移 提交于 2019-11-26 11:50:27
问题 I\'m using XCode 4.2 and have built my UI using Storyboards. I need to create a view that has content above and below a UITableView and I can achieve this by using a UIViewController. A UITableViewController does not let you add content above or below the table. You can use the table header/footer but that doesn\'t work for what I would like to achieve. I now have a UIViewController with a UITableView embedded in it. I can adjust the height and width of the UITableView accordingly which

Is ARC really supported in iOS 4? The iOS 4.2 SDK is missing ARC-related symbols at linking time

由 落花浮王杯 提交于 2019-11-26 08:08:41
问题 I\'ve read and heard since ARC was first announced that it was a compile-time thing and would be backwards-compatible with iOS 4. I have successfully refactored my project to ARC using Xcode 4.2\'s automatic refactoring, and when compiled against the iOS 5.0 SDK, it works fine. However, if I try to compile against my iOS 4.2 SDK, it fails at link time, missing the following symbols: _objc_retainAutoreleaseReturnValue _objc_autoreleaseReturnValue _objc_storeStrong _objc_retain _objc_release

问题 I have the following method in a NSDictionary category, to do a deep copy, which works fine. I just upgraded from Xcode 4.1 to 4.2, and the Analyze function gives two analyzer warnings for this code, as indicated: - (id)deepCopy; { id dict = [[NSMutableDictionary alloc] init]; id copy; for (id key in self) { id object = [self objectForKey:key]; if ([object respondsToSelector:@selector(deepCopy)]) copy = [object deepCopy]; else copy = [object copy]; [dict setObject:copy forKey:key]; // Both

@autoreleasepool without ARC?

由 你离开我真会死。 提交于 2019-11-26 07:35:22
问题 I\'m new to Xcode 4.2, and I\'m not yet fully up to speed on ARC. However, I did read that @autoreleasepool replaces the manual use of autorelease pools and does some special magic under the hood to play nice with ARC. Yet, when I start a new project in Xcode 4.2 specifically with the ARC option turned off I still get @autoreleasepool statements in the template code. What\'s the deal here? 回答1: From http://clang.llvm.org/docs/AutomaticReferenceCounting.html#autoreleasepool: @autoreleasepool

Xcode 4.2 how include one project into another one?

由 坚强是说给别人听的谎言 提交于 2019-11-26 06:57:41
问题 I keep searching, but cannot find a clear and simple explanation on how to include one XCode project, along with all of it\'s sub-classes into another project. I routinely see stuff like that in sample projects that I download off the web, but do not know how to do this myself. Within XCode, along with .h and .m files, and folders, there\'s a whole new project, starting with a blue xcode project icon, that is expandable to contain everything within the project. Please, can someone explain to

由 人盡茶涼 提交于 2019-11-26 03:17:02
问题 I still have Snow Leopard. I have Xcode 4.2 for iOS development. This morning I upgraded my iPhone and iPad to iOS 5.1. But Xcode 4.2 is not detecting my device for testing. I could not find the iOS 5.1 SDK image on Apple\'s developer site, for Xcode 4.2. I don\'t want to do upgrade to Lion to get XCode 4.3 at this time. Will I able to use Xcode 4.2 (on Snow Leopard) for iOS development now? 回答1: To get Xcode 4.2 on Snow Leopard to run code on a device running iOS 5.1 you can do this: If you

Why is @autoreleasepool still needed with ARC?

由 泪湿孤枕 提交于 2019-11-26 00:35:26
问题 For the most part with ARC (Automatic Reference Counting), we don\'t need to think about memory management at all with Objective-C objects. It is not permitted to create NSAutoreleasePool s anymore, however there is a new syntax: @autoreleasepool { … } My question is, why would I ever need this when I\'m not supposed to be manually releasing/autoreleasing ? EDIT: To sum up what I got out of all the anwers and comments succinctly: New Syntax: @autoreleasepool { … } is new syntax for
