问题 I have a project that was started in Objective-C, and I am trying to import some Swift code into the same class files that I have previously written Objective-C in. I have consulted the Apple docs on using Swift and Objective-C in the same project, as well as SO question like this, but still no avail: I continue to get the file not found error after putting in #import "NewTestApp-Swift.h" ( NewTestApp is the name of the Product and module). Here is what I have done so far: In Define Modules ,

问题 I am trying to build an input screen for the iPhone. The screen has a number of input fields. Most of them on the top of the screen, but two fields are at the bottom. When the user tries to edit the text on the bottom of the screen, the keyboard will pop up and it will cover the screen. I found a simple solution to move the screen up when this happens, but the result is that the screen always moves up and the fields on top of the screen move out of reach when the user tries to edit those. Is

问题 Currently working on a universal SpriteKit project. I'll be supporting the following devices: iPhone 4/s, iPhone 5/c/s, iPhone 6, iPhone 6+ iPad non-ret, iPad retina I am confused on the iPhone part. I already have 4 versions for my background sprite for the 4 different screen resolutions of the iPhones. But which goes to which? I know the 3x is for the 6+, and I think the 5/c/s goes to the Retina 4 2x, but I do not know where the iPhone4/s, and 6 go. Anyone know? Side note, when I create a

问题 I'm playing around with SpriteKit in Xcode 6, iOS 8 beta 5. Everything is all laid out and working perfectly on the iPhone 4S simulator, however when switching to the 5S, the elements at the bottom of the screen are cut off. It was to my understanding that the bottom left corner of the iPhone screen should be CGPoint(0, 0) but after checking the location by printing the coordinates to the console that the lowest point of the left corner I could click was around (5, 44). Is there something

问题 In iOS 7, I could change the keyboard type while it is the firstResponder (on the fly): if (textField.text.length > 2) { textField.keyboardType = UIKeyboardTypeNumbersAndPunctuation; } else { textField.keyboardType = UIKeyboardTypeDefault; } [textField reloadInputViews]; // (Omitting some efficiency stuff to keep example to bare bones) This no longer works under Xcode 6/iOS 8. The documentations mostly reflect changes regarding custom keyboard. Using resign/become first responder is (still)

问题 I have installed xcode 6 beta 4 but after that, when I use xcode 5, there is no simulator can be select, so I also cannot build the project, does anyone encounter this problem?

Press it and add the required simulator. 来源： https://stackoverflow.com/questions

问题 Is there a way to access and update the native alarm settings in the iPhone from my app? I need to have a sliding alarm that changes based on the time of year and I want to use the native iPhone alarm for that. Is this possible in the iOS SDK, maybe asking the user for access to the alarm like when your app needs access to the camera or photos for example? 回答1: Unfortunately, I believe there is no public API for accessing the Clock app and settings. I think the reason for this is that Apple
