iphone-5

问题 I have made two different background images for my iPhone app: one in 640x960px (iPhone4s) and one in 640x1136px (iPhone5). But when I create the application layouts in the Xcode 4.5 Main Storyboard, how do I define and create it for both iPhone4s and iPhone5? So that the background automatically updates when i choose iPhone5 screen? 回答1: Just import your background image with the correct suffix For example : myImage.png for non-retina display myImage@2x.png for retina display myImage-568h@2x

问题 According to this rather old, but still current page on Apple's Developer Site (the public portion), there are supposed to be APIs within iOS 6 that allow for access to "real-time video stabilization". Sadly, I cannot find any API documents that seem to support this. Could someone please point me in the right direction? 回答1: Well, I finally found it. Link to Apple API Document Discussion The default value of this property is NO. If the supportsVideoStabilization property contains the value

You'll need Xcode 4.5 to do this. Get started with

Now i

问题 I've been looking for Apple's documentation and posts regarding this issue, but I didn't make it clear how should I deal with this, since most of information I found is about storyboards and autolayout feature. I'm using nib files instead of storyboards, and in addition I need to support iOS 5+, so I can't use autolayout. I'm using Xcode 4.6.3 and I've observed that, in IB, going to the view's Attributes inspector > Simulated Metrics, you can choose its size ("Retina 3.5 Full Screen", "Retina

问题 The iPhone 5 has 3 microphones, according to its product presentation: After looking through the website of iFixit and others I now know where the bottom microphone is and I've identified the one on the back, right next to the camera. There should be another one on the front, at the top, but I can't see it, so I assume it's behind the earpiece/receiver opening. (Is this correct?) I would like to record from two different microphones while the iPhone 5 is lying on it's back. (So the rear mic

问题 I read on the internet that iOS 4.3 with armv7 is the lowest you can go if you want to support iPhone 5. So, if I want my app to run on iPhone 5, then do I need to set the deployment target as iOS 4.3 and set the architecture as armv7? I couldn't find an official documentation for this. Could you correct this information if it's wrong? UPDATE: I've found the answer in the Xcode 4.5 GM seed Release Notes documentation of Apple: Changes in Xcode 4.5: - Support removed for armv6 Xcode 4.5 and

问题 In my Project I have done 90% development using XCode 4.2 (was only need to support 4.x,5.x), Now I need to Build for iOS 6 as well, so I switched to Xcode 4.5 & iOS 6.

Xcode linker Directory not found for option Can anyone please tell me How can I compile "Sqlite3", "MobileCoreServices" frame work for

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 I've added a Default-568h@2x.png launch image to my app. The app needs to display a second launch image after the "real" launch image. Because the UIImage imageNamed: method doesn't automatically load the taller image the way it automatically loads retina images, I've added some code to detect the screen size and display the correct image: -(void)pickRightImage { CGSize result = [[UIScreen mainScreen] bounds].size; UIImageView *imgv = [self loadingImage]; UIImage *img; if(result.height == 480
