CLLocation Manager not updated when App is in Guided Access mode

由 我的未来我决定 提交于 2020-01-25 02:07:57
问题 I kept Guided Access for iPad app. When the app is launched it asks for user's current location using CLLocationManager .This is working under Normal mode and updates user current location. But under Guided Access, popup ("Allow to access your location") is not shown and authorizationStatus is always kCLAuthorizationStatusNotDetermined and doesn't update current location of user . Couldn't understand what could be the problem.Searched a lot but couldn't find it. ViewController.m : - (void

Check whether a CLLocation is based on GPS or cellular

由 左心房为你撑大大i 提交于 2020-01-24 22:22:10
问题 With a 3G GPS device (i.e. iPad 3G) is there a way to know if a reported CLLocation is based on a GPS signal, and not the inaccurate cellular data? 回答1: The CLLocation class has a method called -horizontalAccuracy:. This will give you some idea of the radius of accuracy of that measurement. This is probably better than asking just "is it GPS" because GPS readings can also be pretty inaccurate, depending on receiving conditions and satellite visibility. 来源： https://stackoverflow.com/questions

Script For Assigning Viewport Meta Parameters, iPhone / iPad Conundrum

由 拜拜、爱过 提交于 2020-01-24 17:05:26
问题 I am using a JavaScript snippet to set the content parameters of the viewport meta tag, based on the width of the browser window. The script does almost what it should: it sets the initial scale value for any large screen device as 1, for iPad in portrait mode as 0.5, and for any devices smaller than 700px in screen width, back to 1. However, it seems to ignore the value assigned for iPad in landscape mode: 0.75. I suspect somehow I incorrectly the conditional for width in the landscape mode.

Missing Title Bar in Detail View of UISplitViewController

由 被刻印的时光 ゝ 提交于 2020-01-24 10:49:27
问题 I have a UISplitViewController embedded in a container view (because it's not at the root of my app), the mechanics of which are working nicely except for one issue: The navigation bar for the detail view is missing on the iPad. Initial setup is essentially as follows: In IB, drag a Split View Controller onto the storyboard, which creates a Split View Controller, a Navigation Controller, a Table View Controller (Master), a basic View Controller (Detail), and the segues connecting them. Add a

iPad 3 Retina Display, @2x images, and apps already in the store

由 核能气质少年 提交于 2020-01-24 03:28:25
问题 So some iPad in the future is probably going to have Retina Display. And Apple is most likely going to stick to the @2x paradigm. I've been expecting this for awhile and so I already have @2x artwork for iPad in my apps; some are already in the app store. My question is this: Will I need to recompile and/or resubmit apps to use said artwork when this mythical iPad is released for it to take advantage of these files? Or is this something baked into the OS itself and it should just

Is rotation a requirement for iPad apps?

由 柔情痞子 提交于 2020-01-24 00:12:33
问题 Is it a requirement for iPad apps to be able to rotate? I am looking at a few apps, one example is http://squareup.com they only have one rotation, while others have rotation. What is the exact spec? 回答1: It's not required but I've seen apps butchered for it in reviews. I believe I saw that for the app Facepad. 回答2: You do not have to support rotation; however almost all apps do. 回答3: At least support 180° rotation. Preferably 360°, but this depends on the content your app shows . Fir example
