ios-simulator

问题 I am writing an application which contains some graphs drawn in OpenGL ES. each of these graphs are in a table cell, when I press some of those graphs, it is being opened in full screen mode. Everything worked perfectly since I upgraded to iOS4.2. Now the problem is in simulator, I can't see the drawn graph in cells, but in full screen mode I do see the chart. There are no changes no the device, it is only on the simulator and only in a case. The behavior is the same for other Mac's here.

问题 Why would does this work on simulator but not on a device. I am trying to capture a screenshot of a view that contains more than one AVPlayer.I can snap a frame from a player, but I need the actual screenshot as the view contains a few players, in specific locations on the screen at once. There are multiple threads regarding this topic, but I am yet to find an answer. - (UIImage *) takeScreenShot { UIImage *image; CGSize snapArea = self.view.bounds.size; int bottomTobBarHeight = 44; snapArea

问题 I was working on an iOS app in xCode and I was perfectly using the simulator. Yesterday I had to create a new project and after putting some code I found out that when clicking Run, the app compiles, links, but then the simulator never starts. And stop is disabled. I tried with both iOS sim on and off. Opening the old project back shows the simulator but after switching to the new one, nothing happens. Any ideas on how to fix this? I am using a Single-View app. 回答1: We switch between apps all

问题 I want to ask a question about the iPhone application. Where does the calendar information stored in the iPhone? Is it by using EKEvent? 回答1: The calendar is stored in a SQLite3 database at /var/mobile/Calendar/Calendar.sqlitedb . On the simulator, it is at /Users/<username>/Library/Application Support/iPhone Simulator/User/Library/Calendar/Calendar.sqlitedb . You shouldn't access this database directly. And yes, EventKit is just using this database. 来源： https://stackoverflow.com/questions

问题 I just get this bug,some images on the iOS 8 simulator get distorted.iOS9,and iOS10 don't have this bug. I'm not sure that this is a Xcode 8 bug,or this is my problem. 回答1: Same here, this seems to be a valid Xcode-issue. It is only happening on iOS 8 sims and only with the latest Xcode 8 Beta 6. We should file a bugreport for this. 来源： https://stackoverflow.com/questions/48019309/image-in-assets-xcassets-rendering-error

问题 WatchKit allows us to simulate notifications with an .apns file. How can I do the same thing in an iOS app? (Preferably in the simulator.) The reason I ask is that I want to have the debugger active when the app is initially launched via a notification (i.e. I want to see what happens in the application:didFinishLaunchingWithOptions: method). If I start a new debugging session it will call application:didFinishLaunchingWithOptions: immediately, and then I can never test that code path when I

问题 I am using jquery-mobile and it seems it doesn't detect the landscape setting.
