问题 I am trying to run application using xcode 6 on ios8 simulator but I am getting error "The runtime for selected device is not installed ". I have set the command line tool in preferences but no luck. Please help. 回答1: This just happened to me right after a beta update to Yosemite 10.10 and Xcode 6.6. I still have XCode 5 installed, and I thought it may have been from deleting XCode 6.5, but putting it back in Applications did not help. First, make sure you have all devices installed in your

问题 I want to take a screenshot of my iOS application when it is running in the simulator, and save the screenshot on my Mac. How can I do this? 回答1: It's just as simple as command + s or File > Save Screen Shot in iOS Simulator. It will appear on your desktop by default. 回答2: Use ⌘ + S to capture a screen shot.

问题 On my old Mac running Snow Leopard, I could type "ios" into spotlight and it would start up the iPhone/iPad emulator by itself. I have since had to get a new machine running Lion. I have installed Xcode for Lion, I have installed the developer tool options from the preferences panel. But the "ios" option is no longer there :( The only way now seems to be to run Xcode, create an empty project and then launch emulator with the run option. I have searched and searched the intertubes and the

问题 can i disable wifi in iphone simultaor to test my app? I disconnect pc from network, but the icon of wifi on iphone simulator is always on. 回答1: After disabling your network connection, the icon is still present showing it as enabled, but the connection is of course dead. If you are using the Reachability class or just attempting to ping a URL to verify a connection, the simulator will respond the same way a device with disabled Wifi would, which makes testing on the simulator under these

问题 I am using Alert from react-native. How do I get detox to press the "Log out" button on the alert message? I tried using await element(by.text('Log out')).tap(); But I get "Multiple elements were matched" error. Presumably it finds 3 elements with same label. The original button with label "Log out" used to trigger the alert message, the alert message title, and the alert message button I want detox to press.

问题 Every time I switch Xcode between debugging on my iPhone and running in the simulator it resets the simulated device. I want to run the simulator as an iPhone device, but it keeps changing back to iPad. Does anyone know how to set the configuration so that the simulator defaults to an iPhone device?

问题 This is a new iPhone project, only 1 target (different from this question) On build we get: Failed to launch simulated application: Unknown error. The google again gives us nothing, lots of people have encountered this and there are lots of crazy ideas to try "oh clean the build", "clear the cache", "twiddle this flag" and none of them work and work consistently. We can reproduce this on two different machines with SDK 2.2.1 and 3.0 beta. Not the install on the machines since other iphone
