ios8

问题 I'm trying to convert my iOS 7 app to iOS 8 in Xcode 6 GM, and when i run it on the iPhone 5s or lower simulators with iOS 8 everything is fine, but on the iPhone 6 and 6 Plus simulators, the Status Bar has black text instead of white like it is everywhere anytime else. I've set the Info.plist UIStatusBarStyle to "Transparent Black Style (alpha of 0.5)" thru Xcode, and that seems to have the desired effect everywhere else. Any ideas what is going on? (I haven't touched any of the storyboards

问题 tldr; Auto constrains appear to break on push segue and return to view for custom cells Edit : I have provided a github example project that shows off the error that occurs https://github.com/Matthew-Kempson/TableViewExample.git I am creating an app which requires the title label of the custom UITableCell to allow for varying lines dependent on the length of the post title.

问题 I've tried a number of things and can't seem to reset the badge count from notifications comings from cloudKit. Has anyone else ran into this problem.

No luck... 2) Call the server to clear the badge count CKModifyBadgeOperation *oper = [[CKModifyBadgeOperation alloc] initWithBadgeValue:0]; [oper start]; No luck... 3) Pull in all notification changes

问题 So I'm making a game in which I am dropping objects which have to be destroyed by a spike(triangle) at the bottom of the screen by a user. I cannot work out how to make a UIView that is a triangle. However I have been able to make it work as a rectangle like this: let barrier = UIView(frame: CGRect(x:125, y: 650, width: 130, height:20)) barrier.backgroundColor = UIColor.orangeColor() view.addSubview(barrier) And this has worked. But I cannot work out how to make a triangle. The reason I want

问题 I am trying to mimic the UINavigationController's new hidesBarsOnTap with a tab bar. I have seen many answers to this that either point to setting the hidesBottomBarWhenPushed on a viewController which only hides it entirely and not when tapped. @IBAction func tapped(sender: AnyObject) { // what goes here to show/hide the tabBar ??? } thanks in advance EDIT: as per the suggestion below I tried self.tabBarController?.tabBar.hidden = true which does indeed hide the tabBar (toggles true/false on

问题 When using the old UIWebView you could catch the requests by implementing a custom NSURLProtocol. I us this to handle requests that requires authentication. I tried the same code and it doesn't work with the new WKWebView but my protocol class isn't called at all. Is someone experiencing the same problem or is there a better way of doing authentication with the WKWebView? Without any modifications I get a 401 response in the decidePolicyForNavigationResponse delegate function. I've also tried

问题 I am developing an iOS8 application which supports interactive notification. But I don't have clarity on the features supported by interactive notification and how to send/handle interactive notifications. If any one can give an example, that would be very much helpful for me. Thanks in Advance :) 回答1: First you need to create the notification Action.
