ios-simulator

I program for both iPhone and iPad. When doing iPhone stuff, I prefer the retina iPhone simulator. When doing iPad stuff, I prefer the non-retina simulator. Swapping between them is a two-step process for me. I have to switch xCode from the "iPhone simulator" target to the "iPad simulator" target. The problem is that when I do this, the simulator switches from retina iPhone to retina iPad. I therefore also have to go into the simulator app and change the hardware to non-retina iPad. Is there a way to accomplish that in a single step? Yes! and its super easy. In Xcode 4+ click the dropdown with

I have created an app, and then later changed the core data model. I changed the model and this all works fine during development. However to my surprise, when users download the updated version (with the new core data model), the app keeps the old model from the previous version. This causes the app to crash. Is there some way to simulate an update as if it was updated from the app store? I need to be able to do this in order to test my possible solutions to the problem. You cannot simulate update in XCode, look at this: https://developer.apple.com/library/ios/technotes/tn2285/_index.html You

I got a .app folder from a developer friend. I would try his application and run .app to my iPhone Simulator, without XCode. Is there a way to run this .app to my iPhone Simulator ? Of course this .app has been built for iPhone Simulator target. Try something like this: /Developer/Platforms/iPhoneSimulator.platform/Developer/Applications/iPhone\ Simulator.app/Contents/MacOS/iPhone\ Simulator -SimulateApplication path_to_your_app/YourFavouriteApp.app/YourFavouriteApp 来源： https://stackoverflow.com/questions/7362852/iphone-run-app-to-iphone-simulator

in an iPhone app, I have a UITabBar with three tabs. One has a system image, two more have custom images. These are PNGs, 30x30, palette-based, mostly transparent. These images show up fine in the simulator, but on the device, all I see is a grey gradiented square on a tab. The shapes on these images are grey to begin with, but they do show up as expected on the simulator. Any ideas, please? The image should be white on transparent. It's in the UI design guide. In my case, it was grey on transparent. Simulator forgives that, the device does not. The device itself is pickier about image formats

I want to try some "programming for iphone". For that I need a Mac OS X, no question about it.. But I have a problem I don't have a Mac Computer. I have a Intel Dual-Core PC, running XP. Snow Leopard its for Intel, but for Intel Mac computers, right?. If I manage to install Mac OS X Snow Leopard in my Notebook. Do you think I can still install and do programming for Iphone, as well in a Mac Computer? There will be any problems in the programming or debugging? And there is another thing.. I don't have an iphone. That will may be a problem right? There's a commercial environment which allows to

Is there a way to test code using iPhone camera in the simulator? (Somebody must have written something - you could have a replacement component that simulates the camera) In the simulator there are some sample photo library images that you can access. Use: UIImagePickerControllerSourceTypePhotoLibrary If you want to test your actual camera API usage, you would have to closely emulate a fairly large non-trivial portion of the AVFoundation framework. If you just want to test the rest of your app, you could just ifdef out all the camera related stuff and replace your image capture and preview
