问题 I am doing a app for iPad in which we have added two images one for Landscape and the other for portrait mode, I have written code for. - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { // in this method we have called landscape and portrait frames basing on the // status bar rotation if it is turned to landscape then the landscape image // is called and the textfields frames are set else portrait image is set and // then the textfield frames are

问题 I have seen this question but it is 2 years old. Is there a better\easier\newer way to check if string has numeric values. e.g 1 or 1.54 or -1 or -1.54 etc etc. 回答1: bool status; NSScanner *scanner; NSString *testString; double result; scanner = [NSScanner scannerWithString:testString]; status = [scanner scanDouble:&result]; status = status && scanner.scanLocation == string.length; If status == YES then the string is fully numeric. Or as @Dave points out from this SO answer: NSNumberFormatter

问题 I have to connect to my workplace's subversion. The ip is open on a specific port. I have tried to connect with Tortoise from my Win 7 laptop and it works just fine, so I guess the subversion server and repository is all right. When ever I insert the IP to the subversion server the Repository-wizard in Xcode 4 says it can connect (to the server). But when ever I put the custom port number after with ":" between it cant checkout from subversion. The url I want to connect to is: xxx.xxx.xxx.xxx

问题 When I'm running my app on my device using XCode and I have a crash it's easy tracking where it happened on code. However, when I deploy my ad-hoc version to testers and they have a crash, is there a way for me to load the crash on XCode as if it crashed on my computer, actually seeing the stack and the variable values ? Thanks 回答1: As far as I know, there is no known method to obtain a full core dump file for iOS apps that you can later load on GDB. Are you already asking your testers to

问题 I have a c++ project, add a text file to the project, now I can't read from it I remember in XCode 3 there was property in GetInfo of the Project node, to set the build relative to the project directory and that made it work. But in XCode 4 I can't find such setting or find a substitute I can only reference files if they are with absolute paths. #include <iostream> using namespace std; int main (int argc, const char * argv[]) { //This works freopen("/Volumes/MyHD/XProjects/Test/File.txt", "r"

问题 I've been trying to use Xcode 4 on my 1GB Mac Mini. It's not a happy situation. It frequently slows way down, presumably due to memory shortages. Are there any settings I can change so it won't be such a memory hog? 回答1: Another post here suggests that the problem may be having the "predictive compilation turned on in the Xcode preferences." 回答2: I ended up doing the following. None of them reduced Xcode's memory consumption, but they did reduce the memory needed by other programs, and hence

问题 Using Xcode 4.0.2 , I have a target that compiles, links, and runs properly in the simulator. However when I compile and link it for an iOS device I get the following (full) linker error: Ld /Users/mike/Library/Developer/Xcode/DerivedData/FOObar-ezjrxybxyybadxguvscgaqtaelju/Build/Products/Debug-iphoneos/FrameworkHarness.app/FrameworkHarness normal armv7 cd /Users/mike/src/FOO/FOObar setenv IPHONEOS_DEPLOYMENT_TARGET 4.2 setenv PATH "/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin:

问题 Right now I'm just trying to test my app on my phone and not deploy to the store. How are all these things related? Since I'm not trying to upload to the store, can I ignore any of them? I'm on the University Developer program. I was able to get a certificate and install it in Xcode, but builds still fail. Is solving this problem just a matter of changing the application identifier? How do I know what to put in? One thing I noticed is that in the Developer Portal I see only one App ID but it
