我将Xcode更新到版本8.3(8E162),在我的单元测试文件中,我有这个警告:
通过模块'myframe'隐式导入桥接头'myframe-Bridging-Header.h'已弃用,将在更高版本的Swift中删除
在这条线上:
@testable import myframe
如何修复此警告？
我只有 iOS14 的特定崩溃。我的代码很长一段时间没有改变，所有以前版本的 iOS 上都没有问题，但根据 Crashlytics，我看到了这个堆栈跟踪：
Crashed: com.apple.main-thread
0 libdispatch.dylib 0x19125b7f4 <redacted> + 36
1 libdispatch.dylib 0x1912298c4 dispatch_group_leave + 126

6 libdispatch.dylib 0x191226fd0 <redacted> + 32
7 …我有元素数组(它是一个基本数组).数组的类型是String
basicArray = [1710, 1725, 1740, 1755, 1810, 1825, 1840, 1855, 1925, 1955, 2020, 2050, 2120, 2150, 2220, 2250, 2320, 2350, 2430]
我需要创建两个新数组,其中basicArray的每个元素必须分成两部分,例如:
array1 = [17, 17, 17, 17, 18, 18, 18, 18, 19, 19, 20, 20....]
array2 = [10, 25, 40, 55, 10, 25, 40, 55, 25,55, 20, 50...]
怎么做得更好？感谢您的意见!
我已经为UIButton实现了popover：
@objc func showList(sender: AnyObject?) {
guard let buttonView = sender?.value(forKey: "view") as? UIButton else { return }
guard let popVC = R.storyboard.first.VC() else { return }
popVC.modalPresentationStyle = .popover
let popOverVC = popVC.popoverPresentationController
popOverVC?.delegate = self
popOverVC?.sourceView = buttonView
popOverVC?.sourceRect = CGRect(x: 0, y: 190, width: 0, height: 0)
popOverVC?.permittedArrowDirections = .init(rawValue: 0)
popVC.preferredContentSize = CGSize(width: 150, height: 250)
showedViewController.present(popVC, animated: true, completion: nil)
}
extension VCInteractor: UIPopoverPresentationControllerDelegate {
func adaptivePresentationStyle(for controller: UIPresentationController) -> UIModalPresentationStyle {
return .none
} …我有两个Int数组,例如:
array1 = [1,2,3,4]为Int
array2 = [10,20,30,40]为Int
为了工作,我需要创建字典,其中Key - 它是来自array1和Value的元素 - 它是来自array2的元素,在我的例子中 - [1:10,2:20,3:30,4:40]为[Int:Int].
所以,当我创建循环时:
for i in 0..<arrayOfKeys.count {
dictionaryOfData[arrayOfKeys[i]] = arrayOfValues[i]
}
我只看到最后[4:40],但我知道我必须有4个键值的字典.
请给我,建议,如何快速做到这一点？!
upd,我发现我的问题 - 键必须是唯一的!所以,非常感谢你的回答,我很快就知道了拉链
