小编Asd*_*bal的帖子

我想在Xcode 7上的Swift项目中导入我的自定义模块/框架.我理解如何正常地执行它.但我不想在每次创建新项目时继续拖放框架并将其链接起来.我以为我可以将框架移动到iPhoneOS.sdk /../ Frameworks文件夹和/或iPhoneSimulator.sdk /../ Frameworks文件夹中的文件夹.在不将我的自定义框架拖放到项目中的情况下,我可以导入模块(使用自动完成).但是我收到错误"无法构建Objective-C模块'Tumblr'".在构建设置中是否存在我缺少的设置.

**Tumblr模块是我创建的模块.

我还为iPhoneOS.sdk中存在的框架创建了一个.tbd和module.map文件

我想做动画,例如"在滚动collection view cell结束时滚动注释引脚向上/向下滚动.但是当滚动结束时,如何开始滚动时注释引脚等动画上升,注释引脚变为向下collection view

//code --> For Scrolling
func scrollViewDidEndDecelerating(scrollView: UIScrollView) {
    if scrollView == collectionView {
        NSLog("page collection %d",Int(scrollView.contentOffset.x/scrollView.frame.size.width))
        self.UpdateMapAnotationPin(Int(scrollView.contentOffset.x/scrollView.frame.size.width))
    }
}

//  -->When Update Pin

func UpdateMapAnotationPin(vIndex : Int) {
    if self.mapAnnotations.count != 0 {
        let info = self.mapAnnotations[vIndex]
        let aView = map.viewForAnnotation(info)
        info.imageName = "ic_map_pin1"
        info.tagPin = vIndex
        aView?.image = UIImage(named: info.imageName)

        if aView != nil {
            self.animationWithView(aView!)
        }
    }
}
//   --> For animation

    let point:MKMapPoint  =  MKMapPointForCoordinate(mkView.annotation!.coordinate); …

我刚刚安装Xcode 8 beta 2和iOS 10 beta.我有一个现有的项目,我根据Xcode的提示从swift 2.3更新到swift 3.我的代码数据代码收到错误.

这是由xcode从swift 2.3转换为swift 3时自动生成的

var fetchedResultsController: NSFetchedResultsController<AnyObject>!

我收到的错误是

 Type 'AnyObject' does not conform to protocol 'NSFetchRequestResult'

我试图遵守AnyObject

extension AnyObject: NSFetchRequestResult {}

但我收到另一个错误

我不确定我需要做什么,或者我的fetchedResultsController首先需要更改.

回答: var fetchedResultsController: NSFetchedResultsController<Content>!

我正在制作一个应用程序,扫描反转颜色的条形码(黑色背景和白色条).我必须使用AVFoundation.目前,我正在使用AVCaptureMetadataOutput.我可以使用正常的条形码完美地工作.我需要反转白色的颜色 - >黑色和黑色 - >白色等.我CIColorInvert可以在输入中添加一个AVCaptureSession

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.

    mCaptureSession = [[AVCaptureSession alloc] init];
    AVCaptureDevice *videoCaptureDevice = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];
    NSError *error = nil;

    AVCaptureDeviceInput *videoInput = [AVCaptureDeviceInput deviceInputWithDevice:videoCaptureDevice error:&error];

    if([mCaptureSession canAddInput:videoInput]){
        [mCaptureSession addInput:videoInput];
    } else {
        NSLog(@"Could not add video input: %@", [error localizedDescription]);
    }

    // set up metadata output and this class as its delegate so that if metadata …

我XCTest UI对Mac应用程序进行了相当正常的测试,该应用程序单击应用程序菜单中的某些菜单项以打开窗口.

在某些地方 - 比如我自己的Mac - 测试工作正常.但在其他地方 - 比如Travis CI- 他们失败了,出现了这个错误:

UI Testing Failure - Failed to receive event delivery confirmation within 2.5s of the original dispatch.
...
menuBarsQuery.menuBarItems["Top level menu item"].click()
menuBarsQuery.menuItems["Menu item in sub menu"].click()

系统:

• Mac OS 10.11.5
• Xcode 7.2.1
• Mac OS SDK版本:10.11.2
• Swift 2.1.1

稍微消毒的测试用例版本:

import XCTest

class FooUITests: XCTestCase {

    override func setUp() {
        super.setUp()
        continueAfterFailure = false
        XCUIApplication().launch()
    }

    override func tearDown() {
        super.tearDown()
    }

    func testCanDoSomething() {
        let app …

我有一个for循环,我希望在迭代之间添加延迟.我已将waitUntilDone更改为YES并获得相同的结果.我的数组中只有两个数字,并且在五秒后调用它们而不是:

0s - 没有5s - Block叫10s-Block叫

for(NSNumber* transaction in gainsArray) {

    double delayInSeconds = 5.0;
    dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(delayInSeconds * NSEC_PER_SEC));
    dispatch_after(popTime, dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^(void) {

        NSLog(@"Block");

        [self performSelectorOnMainThread:@selector(private_addTransactionToBankroll:)
        withObject:transaction waitUntilDone:NO];

    });
}

如果重要的话,我正在使用Cocos2d

我正在对一种新的潜在产品进行初步研究。此产品的一部分要求iPhone和iPad上的“语音转文本”功能保持打开状态，直到用户将其关闭为止。自己使用它时，我注意到它要么在30秒钟左右自动关闭，无论用户是否停止讲话，或者在说话者发出一定数量的可疑词后关闭它。无论如何，该产品要求它始终保持打开状态，直到明确要求停止为止。以前有人为此工作吗？是的，我尝试了很好的搜索，似乎找不到任何实质内容，尤其是找不到用正确语言编写的内容。谢谢朋友！

我尝试通过我的应用发送电子邮件，但收到一个错误消息

“请设置邮件帐户以发送电子邮件”。

我的代码块在下面。

import MessageUI

@IBAction func emailTapped(_ sender: Any) {   

    let mailComposerVC = MFMailComposeViewController()
    mailComposerVC.mailComposeDelegate = self
    mailComposerVC.setToRecipients(["abc@gmail.com"])
    mailComposerVC.setSubject("Sending you an in-app e-mail...")
    mailComposerVC.setMessageBody("Sending e-mail in-app is not so bad!", isHTML: false)

    if MFMailComposeViewController.canSendMail() {
        self.present(mailComposerVC, animated: true, completion: {() -> Void in })
    }  
}

func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Swift.Error?){
    controller.dismiss(animated: true) { () -> Void in } 
}

我有一个UIColor extension与enum命名为myColors:

enum myColors {
    static let backgroundColor = UIColor(hex: "#373737")
    static let strokeColor = UIColor(hex: "#FFFCF9")
    static let red = UIColor(hex: "#FF6978")
    static let green  = UIColor(hex: "#BCE784")
    static let blue   = UIColor(hex: "#B1DDF1")
    static let yellow = UIColor(hex: "#FFFD98")
    static let purple = UIColor(hex: "#A09ABC")
}

我试图将sprite颜色随机设置为这些颜色之一(红色,绿色,蓝色,黄色,紫色).我在Stack Overflow上找到的答案很少,但没有一个有用.我试着这样做:

let sprite = Player(x,y,color: myColors(rawValue: myColors.purple.rawValue+1)

但它没有用.紫色是枚举的最后一项,所以我选择了它.

我正在将我的应用程序迁移到4.1并遇到此错误的一些麻烦:

刚刚更新到Swift 3和xCode 8 Beta 4.

修复所有代码问题后,我现在有一个无错误的项目,但是当我点击我的前屏幕上的一个特定按钮时,它会抛出SIGABRT错误.

我确信它与目标页面上的UIPickerView元素有关,因为我已经删除,检查并重新添加了所有的segue和outlet以确保从那一方清楚一切.

控制台显示以下内容:
