问题 I am creating a title bar for my iOS application and I am making this inside a UIView. The only issue I am having is with the "home button". When the home button is pressed, it needs to go to the home page, which is ViewController. However, it doesn't look as if [self presentViewController:vc animated:NO completion:NULL]; works for UIView. How do I work around this problem ? - (void) createTitlebar { CGRect titleBarFrame = CGRectMake(0, 0, 320, 55); //Create the home button on the top right

问题 I already have the base code that supports ios 4.3 to ios 5. Now I would also like to support ios 6.0. The present base code has modal views , hard coded CGRect's , and rotation is different for each view. So I would like to know whether we can support ios 4.3 to ios 6.0 with the same base code, by just tweaking some changes, or do we need to create a complete new target? Like we cannot use auto layout of ios 6.0 if I want to support previous versions as it will lead to a crash. 回答1: Yes, we

问题 So, as by the question, I use the following code to set userinterfaceOrientation for the viewcontroller. - (BOOL) shouldAutorotate { return YES; } -(NSUInteger)supportedInterfaceOrientations { return UIInterfaceOrientationMaskPortrait; } I tried setting UIInterfaceOrientationMaskAll for another viewController. Prior, I checked all the items for Supported interface orientations in the info-plist. Both the viewControllers returned true (as set in the info-plist) for all the orientations and

问题 I am updating our app and I have added the new default image but my tab bar was not working on the iPhone 5. I did some research and created an if statement checking for the size of the display and then placing the tab bar in the proper location. The problem is that when the if statement hits the iPhone 5 screen size and places the tab bar in the right place, the buttons do not work... If I change the vertical location to a lesser value the buttons then work. Here is the code: UITabBar

问题 Is it possible to list my iPhone app in iPhone's native photos app's share/send menu? Some links says not possible. But then how facebook, twitter apps are allowed as those too are native apps not developed by apple. Any help is appreciated. Thanks Sayali 回答1: Apple has made a special exception for Facebook and Twitter because of their integration with iOS. Any other apps cannot do that.
