问题 I have an app that uses TestFlight SDK and other debugging frameworks which I want to remove automatically for App Store release builds. I created a new "App Store" build configuration, but how can I teach Xcode which frameworks I want to be included with this build? And how can I make the code that uses these frameworks conditional so it is excluded from the App Store release build? 回答1: You have three components of the process that work in your favor, to remove extraneous code. First, you

问题 I currently have two classes. Class A has my UIView attached to it. My second Class, Class B has some other functions that works in the background. I have one function that ends up with a string. Is there a easy way to move that string from Class B to Class A that has the UIView. 回答1: Sure -- just make sure that the instance of B has a reference to the instance of A that you want to pass the string to. Rule: Any time you want one object, say foo , to be able to communicate directly with

问题 I'm defining a class 'function' and two others classes 'polynomial' and 'affine' that inherit from 'function'. class function { public: function(){}; virtual function* clone()const=0; virtual float operator()(float x)const=0; //gives the image of a number by the function virtual function* derivative()const=0; virtual float inverse(float y)const=0; virtual ~function(){} }; class polynomial : public function { protected: int degree; private: float *coefficient; public: polynomial(int d);

问题 In the xcode, after you creating a UIViewController subclass, in the viewDidUnload method, there is a comment added by xcode: - (void)viewDidUnload { [super viewDidUnload]; // Release any retained subviews of the main view. // e.g. self.myOutlet = nil; } Here, xcode recommends us to use self.myOutlet=nil to release object. But in xcode4, there is a cool feature: you can just drag a Interface Builder outlet to its owner's header file, then xcode will automatically create the IBOutlet object

问题 I've created a View Based Application in XCode4 ; when creating the application I selected iPhone as the Device Family : The application was created with the following files: I designed the UI on the TestushViewController.xib file and without adding any code in the Delegate files, the application is uploading immediately to the TestushViewController.xib view and I'm very happy about it. Now I want to add an iPad xib . How do I do that? (I knew how to do it in XCode 3, but I used some code in

问题 I've created a View Based Application in XCode4 and trying to do the code and UI design according to the way Apple have intended it to be. So I designed the UI in the AppNameViewController.xib and it works fine; now I want to enable it as a UNIVERSAL application that runs on iPad as well. I changed the App-Target>>Summary>>Devices from iPhone to Universal and miraculously XCode had automatically created MainWindow-iPad.xib (Apple, very nice...), but since I designed the application first

问题 I have iPhone app and I converted it in xcode4 to universal app, and it worked fine, but after that I deleted MainWindow-iPad and return to iPhone app only. Now I need to make my app universal again, I clicked in Xcode4 "Devices-Universal", but XCode don't create MainWindow-iPad and don't ask me "Transition to universal target" so when I'm building and running in iPad simulator app crashes. How can I fix this? Thank you. 回答1: Create your own mainwindow-ipad nib file and set it as main nib

问题 load a xib file as a UIView, and I got a UITextField form a Xib file(it just a view that contains textfield and button). But when the app launched and that textfield comes up. i cannot type any alphabet on this UITextField. But paste a text to that UITextField was OK. Why? Here is my adding code -(IBAction)showSheet{ UIView *myView = [[[NSBundle mainBundle] loadNibNamed:@"LoginViewComp" owner:self options:NULL] lastObject]; [myView setFrame:CGRectMake(0, 44, 320, 400)]; UIButton *btn1 =

问题 This is in Xcode 4.5 Organizer on the 'Projects' screen. I have lots of snapshots including many made after updating to Xcode 4.5. If I select one of them (it doesn't matter which one) then click "Export Snapshot" I get a dialog box with this message: fatal: ambiguous argument 'ae30b7dea8b5..a934b593abf6': unknown revision or path not in the working tree. Use '--' to separate paths from revisions. This makes all of my snapshots useless. Can anybody explain what's going on and how to get
