问题 In iOS 7, when navigating back using the new swipe-from-edge-of-screen gesture, the title of the Back button ("Artists") fades from being pink (in the example below) and having regular font weight to being black and having bold font weight. It seems to me that the animation uses two different labels in order to achieve this effect; one fading out as the other fades in. However, Apple has somehow adjusted the font so that the regular label perfectly overlays the bold one, thus creating the

问题 I've been looking all over the place for the required bluetooth connection parameters that will work for all three of these operating platforms.

问题 So I tried to create an infinite scrolling background by using this post's solution (Sprite kit side scrolling). However, I would want to make the image repeatable. As you can see in the video below, after the image has finished it's horizontal way, there is some empty gap.. I would like to make the image fill that gap, so repeat it endlessly. http://www.youtube.com/watch?v=kyLTGz7Irrc or https://vimeo.com/79555900 (password: spritekit) What I did : for (int i = 0; i < 2; i++) { SKSpriteNode

问题 I've read every tutorial I've found about UIPageViewController, but they show just basics, I'd like to create something like new twitter app has: UIPageViewController is embedded into Navigation controller, title of navigation bar is based on current page and those page dots are there as well, user can tap on item on current page(item from table view/collection view) to see detail.

问题 I want to know if there is a way to change the iOS 7 status bar text color besides black and white color? 回答1: Theoretically this is possible. You will need to read about private api's on iOS. Here is o good place to start with UIStatusBar example: http://b2cloud.com.au/tutorial/using-private-ios-apis/ Keep in mind that probably you won't be able to submit your app on Appstore if you would use private api. 回答2: Put this in your AppDelegate application:didFinishLaunchingWithOptions: Swift 4.2:

问题 I've got an app that uses a UIWebView , and everything was (and still is) working perfectly on iOS 6. On iOS 7, though, it is sometimes kicking back an error ImageIO: PNG not a PNG file when I try to load certain PNG files, (for example this one). Now, obviously the PNG files aren't corrupted because they work on iOS 6 and they sometimes work even on iOS 7, but then sometimes they kick back that error. I can't find any common cause that determines when the error happens, and I'm not doing

问题 I have the following setup: Bluetooth scanner iPad Webpage with a textfield for scan input Usage: User focus textfield and scan barcode with bluetooth scanner Scanner adds ENTER (13) at the end of the scan Problem: On Safari in IOS7 there seems to be a change on how keyboard events are handled on bluetooth devices.

问题 I am trying to use the new iOS7 MKMapSnapshotter to generate a static map image. Whenever my app needs a map, I call the following: MKMapSnapshotter *snapshotter = [[[MKMapSnapshotter alloc] initWithOptions:theOptions] autorelease]; dispatch_queue_t aQueue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_BACKGROUND, 0); DebugLog(@"Snapshotter allocated %@ and run on queue %@", snapshotter, aQueue); [snapshotter startWithQueue:aQueue completionHandler:^(MKMapSnapshot *snapshot, NSError

问题 I am having a problem getting localization on iOS to work the way I think it is suppose to, but this is my first foray into localization so maybe I am misunderstanding. I have three Localizable.strings files: Base "TAB_TITLE_Camera" = "CAMERA"; English "TAB_TITLE_Camera" = "Camera"; Spanish "TAB_TITLE_Camera" = "Cámara"; NSLocalizedString(@"TAB_TITLE_Camera", nil) iOS 6.1 On Xcode 5 with a 4th generation iPod Touch running iOS 6.1 , English and Spanish seem to work, but if I change to German

Here is my code, can anyone point me in the correct direction? -(IBAction)click_select_fruit_type { select_dialog = [[[UIAlertView alloc] init] retain]; [select_dialog setDelegate:self]; [select_dialog setTitle:@"Fruit Type"]; [select_dialog setMessage:@"\n\n\n\n"]; [select_dialog addButtonWithTitle:@"Cancel"]; idType_table = [[UITableView
