问题 I'm currently working on the simulator. I'd like to save an UIImage to a jpg file, on my desktop. It seems that I have a problems with paths or something. Thank you for your help :) 回答1: The following should get you started... myImage is an UIImage object.

问题 nw_host_stats_add_src recv too small, received 24, expected 28 So I'm getting this appear in the console and I'm not sure whether it is an issue that I should be bothered about or not.

Thanks! 回答1: This is a bug with logs in Xcode8 + iOS10. We can get round it in this way: When on simulator , add the

问题 TL;DR: It seems localization does not work with xCode 6.1 and 8.1 simulator. Workaround: Go to "edit schemes" >> "Run" (side bar) >> "Options" tab >> "Application Language" Select the language you wish to run the app on the simulator. Long Story: I've updated xCode to 6.1. The update deleted the iOS 7.x simulators and left me only with 8.x simulator.

I have the following code in AppDelegate . - (BOOL) application: (UIApplication *) application didFinishLaunchingWithOptions: (NSDictionary *) launchOptions { UIScreen *screen = [UIScreen mainScreen]; NSLog(@"Screen width %.0f px, height %.0f px, scale %.1fx", (double) screen.bounds.size

问题 I have added the UIBackgroundModes property in Info.plist to have an array entry of " audio " and have added the call to setup the audio session: [session setCategory: AVAudioSessionCategoryPlayback error: &error]; .

问题 Is there any way to test the iPhone camera in the simulator without having to deploy on a device? This seems awfully tedious. 回答1: There are a number of device specific features that you have to test on the device, but it's no harder than using the simulator. Just build a debug target for the device and leave it attached to the computer. List of actions that require an actual device: the actual phone the camera the accelerometer real GPS data the compass vibration push notifications... 回答2: I
