我需要绘制一个rect带有阴影的画布，其四个侧面都有阴影rect，类似于 div 的样式为"box-shadow":"0px 0px 5px 5px"

我需要使用Swift代码获取本地IP地址和子网掩码.

请帮帮我.我有一些代码在Objective-C中工作.如何在Swift中获取等效代码？

下面我添加了Objective-C代码:

+(NSDictionary *)getLocalIPAddress{ 
NSDictionary *dictIPDetails; 
NSString *address = @"error";
NSString *netmask = @"error";
struct ifaddrs *interfaces = NULL;
struct ifaddrs *temp_addr = NULL;int success = 0;

    // retrieve the current interfaces - returns 0 on success
    success = getifaddrs(&interfaces);

    if (success == 0)
    {
        temp_addr = interfaces;

        while(temp_addr != NULL)
        {
            // check if interface is en0 which is the wifi connection on the iPhone
            if(temp_addr->ifa_addr->sa_family == AF_INET)
            {
                if([@(temp_addr->ifa_name) isEqualToString:@"en0"])
                {
                    address = @(inet_ntoa(((struct sockaddr_in *)temp_addr->ifa_addr)->sin_addr));
                    netmask …

这是我的整个代码.我想提供一个来自youtube的视频ID,以获取与此vedio ID相关的评论.但总是表明我的权限不足.

我试图解决这个问题,发现youtube .commentThreads().list("snippet").setVideoId("tLTm_POao1c") .setTextFormat("plainText").execute();是问题所在.具体来说,execute()在这一行中称为"权限不足".为什么是这样？

    return x;
}

为什么我会收到此错误？我还尝试将所有“ IEnumerable”更改为“ List”，请帮帮我！谢谢 ：）

无法将类型'System.Collections.Generic.List'隐式转换为'System.Collections.Generic.IEnumerable'。存在显式转换（您是否缺少演员表？）

我正在尝试使用 Web 服务将数组返回到我的 GUI，但我不知道如何从WebResponse.

这是 GUI 中调用 Web 服务的方法：

public static ArrayList getList()
{
    String[] list;

    WebRequest request = WebRequest.Create("localhost:8080/test");
    WebResponse response = request.GetResponse();
    list = ??? //<--What do I put here to actually access the returned array?

    return response;
}

我不知道如何在iOS 9中更改引脚颜色的代码(因为最近Apple更改了它的代码),而且我在Swift中仍然是新手.所以,我现在不知道如何集成pinTintColor我的代码.

请在下面找到我的代码:

import MapKit

class ViewController: UIViewController, MKMapViewDelegate {
    @IBOutlet var map: MKMapView!

    override func viewDidLoad() {
        super.viewDidLoad()

        let annotation = MKPointAnnotation()
        let latitude:CLLocationDegrees = 40.5
        let longitude:CLLocationDegrees = -74.6
        let latDelta:CLLocationDegrees = 150
        let lonDelta:CLLocationDegrees = 150
        let span:MKCoordinateSpan = MKCoordinateSpanMake(latDelta, lonDelta)
        let location:CLLocationCoordinate2D = CLLocationCoordinate2DMake(latitude, longitude)
        let region:MKCoordinateRegion = MKCoordinateRegionMake(location, span)

        map.setRegion(region, animated: false)

        annotation.coordinate = location
        annotation.title = "Niagara Falls"
        annotation.subtitle = "One day bla bla"
        map.addAnnotation(annotation)
    }

这是API的错误吗？

我想编写过滤器,并httprequest在控制器之前获取客户端并制作一些代码,取决于URL.

请求可以是:HttpRequest,MultipartHttpServletRequest,可POST还是GET.如果此请求的URL开头,我需要向另一个REST API发出请求api.

我目前有一个 Swift 应用程序，可以将正方形的填充颜色从红色更改为绿色。我希望发生的是，当动画完成后，我想执行更多代码。

这是我的文件：

import UIKit

class PathViewController: TapToCloseViewController {

    override func viewDidAppear(animated: Bool) {
        super.viewDidAppear(animated)

        let tempView = UIView(frame: CGRectMake(0,0,100,100))
        tempView.layer.borderColor = UIColor.blackColor().CGColor
        tempView.layer.borderWidth = 2
        view.addSubview(tempView)

        let bounds = CGRect(x: 0, y: 0, width: 100, height: 100)

        // Create CAShapeLayerS
        let rectShape = CAShapeLayer()
        rectShape.bounds = bounds
        rectShape.position = tempView.center
        rectShape.cornerRadius = bounds.width / 2
        tempView.layer.addSublayer(rectShape)
        tempView.backgroundColor = UIColor.redColor()

        // Apply effects here

        // fill with white
        rectShape.fillColor = UIColor.greenColor().CGColor

我有一个AVAudioPlayer存储在名为"播放器"的属性中.当用户单击按钮时,它会触发此代码:

@IBAction func restartPressed(sender: AnyObject) {
    player.play()
}

当用户非常快速地连续两次单击按钮时,就会出现问题.

如果第一次点击的声音仍在播放,则似乎忽略了第二次调用.

相反,我想要:

a)第二次点击按钮时,从头开始重启播放器; 要么

b)同时播放声音的两个"实例".

我将如何实现其中一个或两个选项？
