问题 I have implemented actionsheet in my project having deploy target ios7 and less actionsheet works fine. UIActionsheet in Ios8 not working same as other version of Ios. How i make it working properly? Thanks 回答1: UIActionSheet is deprecated from iOS8, You should use UIAlertController. You have to choose the alert style: it could be an AlertView or a Sheet. Check here for Apple reference. See this for an example. 来源： https://stackoverflow.com/questions/26336252/uiactionsheet-in-ios8

问题 I wanted to build a simple demo app using the new LocalAuthentication framework and Swift. I made a new Single View project, and added one line to the top of the ViewController.swift file: import LocalAuthentication Whereupon Xcode tells me there is no such module. Obviously very new to Swift, what am I doing wrong? 回答1: Same problem occurs with Objective-C code. Seems like it is an issue of beta 1. If you run your project on an iOS 8 device (tested on a 5s iPhone), it will work. But it doesn

问题 My app has one big problem. Mainly on iOS 8 because we have not found this on other iOS versions. It will freeze sometimes when push to a new view controller or pop to a previous view controller. But something strange is if you press home button and launch the app from background. It will run a little. Here I mean the new pushed or popped view controller appeared but you still could not push or pop new view controllers. update: The memory, CPU and disk usage are all normal when the app freeze

问题 I have an app with a UIWebView and I need to change it into WKWebView. Everything works perfectly, except when the webView needs to be with contentInset that is not 0. The problem is, the WKWebView doesn't receive touches outside of the bounds of its scrollView's contentInset. I've made a simple example app for testing it: - (void)viewDidLoad { [super viewDidLoad]; WKWebViewConfiguration *config = [[WKWebViewConfiguration alloc] init]; self.wkWebView = [[WKWebView alloc] initWithFrame:self

问题 I am experiencing an odd problem with legacy code running in iOS8. The code was originally written pre-iOS6, pre-storyboards (using nibs) and functioned without issue on iOS7. However, strange behavior began to occur when running on iOS8. The app is set to run only in landscape (left or right). Therefore it should support autoRotation from landscape-left to landscape-right. The first problem was that the initial view controller was loaded in portrait and one side was cut off. This issue was
