EDIT: You can use Refactoring to find where a specific variable is referenced. Select the variable and choose Edit->Refactor->Rename. In the refactoring screen,

问题 I'm trying to add some Tests for my application. Following the Document from Apple, I add two testing bundles to my project. The logic tests are no problem, but when I try to make the application tests on a device I always get the error that the logic tests don't run on a device. In Xcode 3 there is no problem with that. Only Xcode 4 throws this error... Any suggestions? Thanks, Tim 回答1: i was also having problems with setting up application tests in xcode4. A solution that worked for me was

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 5 years ago . In my project the app launches in ViewController, which loads inside a table (Table class) by adding it as a subview (ViewController.h - [self.view addSubview: Table.tableView];) Camera Class is the detailed view, so when you tap in a table row it loads Camara.xib. Until here everything works fine. The problem

问题 Am having some trouble hooking up instance variables in the visual object editor using Xcode4. Have been able to connect the Whereami App Delegate to the mapView and activityIndicator, but for some reason, can't find the locationTitleField. Am also having trouble connecting the delegates back to the App Delegate. What am I doing wrong? Here is the code for Whereami App Delegate.h: #import <UIKit/UIKit.h> #import <CoreLocation/CoreLocation.h> #import <MapKit/MapKit.h> @interface

问题 I noticed after upgrading from 4.2 to 4.3.1 that there is no longer a 32 bit mode option in the Get Info for Xcode. How would I run Xcode 4.3.1 in 32 bit mode now? 回答1: You can't. Xcode is now 64-bit only -- there's no 32-bit code in it anymore. If you had some plugins which were previously 32-bit only, you will need to upgrade them. 回答2: If you run your mac in 32 bit mode (when you start the computeer with "3" and "2" key) you will have your machine and their programs in 32 mode. 来源： https:/
