ios7

问题 There are different solutions for the issue when you go to the background in the iPhone or iPad and the sound continuous playing, the most of them for the HMTL5 audio tag, but are not relevant if you are using Web Audio API because there are not an event like "timeupdate" and is a different concept of course. The Page Visibility API works in iOS7 only if you change of tab, but doesn't if you go to the background, in iOS6 not at all. Someone knows any way to stop/mute a sound using Web Audio

问题 Im trying to change the color of the unselected images in the tab bar, by default they are changed to gray, even if the image is another color. I already search this, but the answers are only for iOS 6 or below. 回答1: This drove me mad just recently so I wrote my own class to handle it that works with every version of iOS I've tried it on ;) Its really easy to extend to do whatever you want it to do too! GozTabBar.h: #import <UIKit/UIKit.h> #import "GozTabBarItem.h" @protocol GozTabBarDelegate

问题 set cell.selectionStyle = UITableViewCellSelectionStyleBlue , or even manually set Blue in storyboard, but neither of them works. if using setSelectedBackgroundView: , it may work.

I want to create a collidable custom shape (from any SpriteKit kind) filled with a pattern image. I've tried the following: UIBezierPath *path = [[UIBezierPath alloc] init]; [path addArcWithCenter:CGPointMake(0.0, 0.0) radius:50.0 startAngle:0.0 endAngle:(M_PI*2.0) clockwise:YES]; SKShapeNode *shape = [[SKShapeNode alloc] init]; UIImage *patternImg =

问题 I'm trying to set up a very simple UIAlertView with a text edit, an Ok and a cancel button, and I want to disable the Ok button based on the content of the text edit. To be able to retain the delegate so that he doesn't go away before the alert view (and thus cause a crash as soon as the user does something with the alert view), I've subclassed it. Now, I want to be able to forward the otherButtonTitles argument from my init method to the UIAlertView init method, but for some reasons, simply

问题 PROBLEM STATEMENT When attempting to save a record to a read/write store that is one of two SQLite stores assigned to the same PersistentStoreCoordinator, my iPhone app crashes. One obvious issue when saving a record is the PersistentStoreCoordinator does not know in which Store to save the data (only because I don't know how to make this happen). First I will provide the big picture to make sure my approach is sound. Then I will supply the implementation details. BACKGROUND This is a

问题 I am deploying a test version of my app over the air to my beta testers. Before iOS 7, I could get their UDID by having them install an app like UDID Pro and having them email it to me. How do I get the UDID from my beta testers if they have iOS 7, so I can set up the provisioning profiles for the Ad Hoc distribution of my app? 回答1: Getting UDID programmatically will not work from iOS7.0 and upwards, since Apple apparently has moved it to "Private API" space for security reasons. However, you

问题 I have searched all over StackOverFlow but did not find any answer on how to use Required Device Capabilities or UIRequiresPersistentWiFi . How do I set values in my application such that the app only works on cellular data/WiFi in the iPhone? Currently I have set the string WiFi property in the Required Device Capabilities Array according to iOSDeviceCompatibility.
