xcode4

问题 Note: This question is related to Warn on calls to UIKit from background threads but does not give an answer on two of the approaches below. I have a problem where the app screen blinks rapidly. I already had that problem in the past and it is due to updating the UI elements outside the main thread. Therefore I've put the following code in many places: assertMainThread(); which is: #define assertMainThread() NSAssert([NSThread isMainThread],@"Method called using a thread other than main!") Of

问题 I'm trying to get route-me offline maps to compile in xCode 4. They were fine in xCode 3. I believe my issue is with architecture settings. Looking at the following post, it looks like I should change proj4 to be armv6 only and leave the main project and mapview at standard (v6 & v7). However, I still get the following errors: Undefined symbols for architecture armv6: "_OBJC_CLASS_$_RMMarker", referenced from: objc-class-ref in OSMapViewController.o "_OBJC_CLASS_$_RMDBMapSource", referenced

问题 I'm working on a project where I'm going to eventually have a library of code that will be used by multiple applications. In reading though the documentation it sounded like creating an XCode4 workspace and 2 projects (1 library, and 1 application) was the way to go. I did this and everything appeared to be working just great. However, today I did a bunch of work on my library project and when I run my application to test my library changes it appears to always be including an older compiled

问题 Does anyone know why this does not work? With this, just one tab bar load the view, the other make black screen. I Have tried without Navigation Controller, and Tab bar is correct and the other doesn't show the tabBar item in running mode. 回答1: My answer for this problem if anyone is interested. Add two views that will launch the view we are interested. Same file for this 2 views : @interface PushToAgenceViewController : UIViewController @end -(void) viewWillAppear:(BOOL)animated { [self
