问题 Having trouble getting unit tests set up for a specific scenario. Here's what I'm trying: In Xcode 4.5, I created a simple OSX "Command Line Tool" application project (Foundation). Note that Xcode does not provide the option to add unit tests to a "Command Line Tool" project automatically – so please don't suggest ticking the ticky-box; it ain't there :-/ In my project, I created a trivial example class that I'd like to test; e.g. "Shape". I followed instructions in Apple's Xcode Unit Testing

问题 I am linking a static framework for iOS, against an armv7 ios 6 application, I suspect that the original binaries are from XCode 3.x and were compiled with GCC, and that I'm now linking it using CLang compiler. I do not have the source code for the framework, only the binaries: (null): warning: (armv7) /.../DerivedData/.../armv7/HardwareObjectFile.o unable to open object file I get 69 warnings like the above, one for every .o file linked into the static framework. Is this warning serious for

问题 I noticed that sometimes on viewDidLoad I got the view size right. Sometimes I don't. For example - (void)viewDidLoad { [super viewDidLoad]; self.pullToRefreshController = [self.pullToRefreshController initWithDelegate:self]; PO(self.view); PO(self.view.superview); PO(self.view.superview.superview); PO(self.view.superview.superview.superview); while(false); } -(void)viewWillLayoutSubviews { PO(self.view); PO(self.view.superview); PO(self.view.superview.superview); PO(self.view.superview

问题 Trying to make my app work with both iPhone 5 and iPhone 4/4s. I tried the "AutoLayout" but does not seem to work for my app also read that it is not supported in iOS 5. AutoLayout specifically fails on a view controller that has an UIScrollview and a UIPicker that is re-sized in code. Having two Storyboards one for 4 inch and one for 3.5 inch seems the way to go. The two Storyboard aproch seem to be the solution for me. So this leaves me with two questions; Where should the code to detect

问题 I am new to iOS app development. I want to create a Calculator App in iOS that has split view. The left side is the "History" Feature in Scroll View and the right side is the calculator itself. Now, regarding the History feature of this app, I am thinking that my program needs to recognize what has been pressed and display it on the Scroll View when the Equal (=) button is pressed. Do you have any idea how will this go on Objective-C? I am using XCode 4.5 and iPhone Simulator 6.0. Thanks in
