xcode4.6

问题 I heavily use the c++0x/c++11 features in my project, particularly code blocks and shared pointers. When I upgraded my OS to 10.8 Mountain Lion (Edit: From 10.7), I was forced to upgrade Xcode. In upgrading Xcode, I lost the ability to compile my c++ project for deployment on 10.6 systems as I get the following error. clang: error: invalid deployment target for -stdlib=libc++ (requires Mac OS X 10.7 or later) It appears that Apple is trying to force people to upgrade by not allowing

问题 xcode 4.6 (4H127), xcode 4.6.3 (4H1503): A simple lower/uppercase conversion of a string with an accented char crashes, depending on the setting of Deployment Target. Code snippet: NSString *lc1 = @"Bosnië-Herzegovina"; NSString *lc2 = [lc1 lowercaseString]; NSString *uc3 = [lc1 uppercaseString]; NSLog( @"\nlc1=%@\nlc2=%@\nuc3=%@ ", lc1,lc2,uc3); The "ë" is simply typed as "opt-u e", the source code file is regular UTF Unicode. lc1 looks as expected in the debugger. But, lc2 and uc3 strings

问题 I did some searching and the answer is still unclear to me. I am trying to create an instance of a UISearchDisplayController inside a TableViewController (TVC). In the header of my TVC, I declared a searchDisplayController as a property: @interface SDCSecondTableViewController : UITableViewController @property (nonatomic, strong) NSArray *productList; @property (nonatomic, strong) NSMutableArray *filteredProductList; @property (nonatomic, strong) UISearchDisplayController

问题 I've started a new project in Xcode (a command line app using C++), and am encountering a problem I haven't had in my other projects: I can successfully commit files, but can't push them to the repo, under the pretence that the changes haven't been committed yet (which they have). There's a question here with the same issue, but none of the answers there solve my problem. In the organizer, under the remote repo I've set up, the commits show up, comments and all, but I still can't manage to

问题 I have a UITextField that I need to select programmatically so when the user taps on a date in a UIDatePicker, it will be sent to that UITextField. This is the code I have, which does not select the UITextField; I have tried all possible combinations of UIControlEvent , but none of them work. Any other ideas? // set textField parameters if([whichTextField isEqualToString:@"oStartTime"]) { oStartTime.backgroundColor = [UIColor colorWithRed:252.0/255.0 green:255.0/255.0 blue:197.0/255.0 alpha:1

问题 I have a project that I created before iPhone 5 was released and I'm working on this project in xCode 4.6. By default xCode changes the build architecture of new projects to include the latest iPhone 5 instruction set. One of the issues I faced is that a static library that I'm using for the project is not compiled for armv7s (new iPhone 5 and possibly new iPad). The workaround is to change the valid architectures property during my debugging of the project to exclude armv7s: I'm interested

问题 I'm developing a new application for Iphone, using Xcode (Version 4.6 (4H127)) and the iPhone 6.1 simulator (Versión 6.0 (369.2)). At the beginning everything was great: every time I pressed the "run" button, the application was loaded into the simulator and I was able to test it. But sometimes it is not working: when I press the run button, I only get the message "Finished running on iPhone 6.1 Simulator". The code successfully compiles (only minor warnings). The main problem is that when I
