//一、*项目准备
1、QQ音乐App 界面素材：(我使用PP助手，将QQ音乐App备份，解压ipa文件 即可得到里面的图片素材)
2、豆瓣电台接口:"http://douban.fm/j/mine/playlist?channel=1"
//二、*界面布局
使用Xcode新建一个Single View Application项目，选择Swift语言。
导入素材图片、在默认的ViewController视图进行以下布局。
界面控件不多，如图将几个关键控件布局就可以了。
//三、*背景模糊特效
布局好就马上要写代码了，写完将会看到一个非常漂亮的效果
首先将控件关联到ViewController
1 @IBOutlet weak var photoBorderView: UIView! 2 @IBOutlet weak var progressSlider: UISlider! 3 @IBOutlet weak var backgroundImageView: UIImageView! 4 @IBOutlet weak var photo: UIImageView! 5 @IBOutlet weak var playButton:UIButton! 6 @IBOutlet weak var titleLabel: UILabel! 7 @IBOutlet weak var artistLabel:UILabel! 8 @IBOutlet weak var playTimeLabel:UILabel! 9 @IBOutlet weak var allTimeLabel:UILabel!
在viewDidLoad方法里，写上模糊特效
override func viewDidLoad() {
super.viewDidLoad()
//将图像变圆形
photo.layer.cornerRadius=self.photo.frame.size.width/2.0
photo.clipsToBounds=true
photoBorderView.layer.cornerRadius=self.photoBorderView.frame.size.width/2.0
photoBorderView.clipsToBounds=true
//模糊效果
let blurEffect=UIBlurEffect(style: UIBlurEffectStyle.Dark)
let blureView=UIVisualEffectView(effect: blurEffect)
blureView.frame=self.view.frame
backgroundImageView.addSubview(blureView)
//设置slider图标
progressSlider.setMinimumTrackImage(UIImage(named: "player_slider_playback_left.png"), forState: UIControlState.Normal)
progressSlider.setMaximumTrackImage(UIImage(named: "player_slider_playback_right.png"), forState: UIControlState.Normal)
progressSlider.setThumbImage(UIImage(named: "player_slider_playback_thumb.png"), forState: UIControlState.Normal)
}
运行一下，看看是不是很漂亮。
//四*让图片旋转起来
先把下面这个方法写上，想看到效果就在viewDidLoad（）方法里加上 rotationAnimation()进行调用。
//图片旋转动画
func rotationAnimation(){
let rotation=CABasicAnimation(keyPath: "transform.rotation.z")
rotation.timingFunction=CAMediaTimingFunction(name: kCAMediaTimingFunctionLinear)
rotation.toValue=2*M_PI
rotation.duration=16
rotation.repeatCount=HUGE
rotation.autoreverses=false
photo.layer.addAnimation(rotation, forKey: "rotationAnimation")
}
//五*弹出播放列表页
新建一个PlayListView.swift和PlayListView.xib并将xib的class关联到PlayListView
将PlayListView.xib进行布局
//弹出方法
//显示
func showPlayListView(){
UIApplication.sharedApplication().keyWindow?.addSubview(self)
//动画从下向上进入
var vbFrame:CGRect = self.viewBackground.frame
vbFrame.origin.y=vbFrame.origin.y+vbFrame.size.height
self.viewBackground.frame=vbFrame
UIView.animateWithDuration(0.15, animations: { () -> Void in
var vbFrame:CGRect = self.viewBackground.frame
vbFrame.origin.y=vbFrame.origin.y-vbFrame.size.height
self.viewBackground.frame=vbFrame
});
}
//关闭方法（将关闭按钮，和viewTouch的点击事件，关联此方法）
//关闭
@IBAction func closePlayListView(sender: AnyObject) {
self.removeFromSuperview()
}
//弹出我关闭方法都写好了，下面就在ViewController页，调用此视图让其弹出来
@IBAction func showPlayList(sender: UIButton) {
NSLog("----click---")
var playList:PlayListView=NSBundle.mainBundle().loadNibNamed("PlayListView", owner: self, options: nil).last as PlayListView
playList.showPlayListView()
}
//六、请求网络数据
请求使用到一个封装类：HttpProtocol.swift
import UIKit
protocol HttpProtocol{
func didRecieveResults(results:NSDictionary)
}
class HttpController:NSObject{
var delegate:HttpProtocol?
func onSearch(url:String){
NSLog("请求地址:%@", url)
var nsUrl:NSURL=NSURL(string:url)!
var request:NSURLRequest=NSURLRequest(URL:nsUrl)
NSURLConnection.sendAsynchronousRequest(request, queue: NSOperationQueue.mainQueue(), completionHandler: {(response:NSURLResponse!,data:NSData!,error:NSError!)->Void in
if (data != nil){
var jsonResult:NSDictionary=NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: nil) as NSDictionary
self.delegate?.didRecieveResults(jsonResult)
}
})
}
}
新建一个实体类Song.swift用来存放请求的数据
import Foundation
class Song: NSObject {
var adtype:NSNumber = 0.0
var aid:NSString = ""
var album:NSString = ""
var albumtitle:NSString = ""
var artist:NSString = ""
var company:NSString = ""
var kbps:NSNumber = 0.0
var length:NSNumber = 0.0
var like:NSNumber = 0.0
var monitor_url:NSString = ""
var picture:NSString = ""
var public_time:NSString = ""
var rating_avg:NSString = ""
var sha256:NSString = ""
var sid:NSString = ""
var songlists_count:NSNumber = 0.0
var ssid:NSString = ""
var subtype:NSString = ""
var title:NSString = ""
var url:NSString = ""
}
将请求的数据转化了实体集合
var eHttp:HttpController = HttpController()
//请求网络数据
eHttp.delegate=self
eHttp.onSearch("http://douban.fm/j/mine/playlist?channel=1")//华语
//请求网络数据结果
func didRecieveResults(results:NSDictionary){
NSLog("请求到的数据:%@", results)
if (results["song"] != nil) {
let resultData:NSArray = results["song"] as NSArray
let list:NSMutableArray = NSMutableArray()
for(var index:Int=0;index<resultData.count;index++){
var dic:NSDictionary = resultData[index] as NSDictionary
var song:Song=Song()
song.setValuesForKeysWithDictionary(dic as NSDictionary)
list.addObject(song)
}
self.tableData=list
self.setCurrentSong(list[0] as Song)
}
}
//七、*将请求后的第1条数据设置为当前将要播发的歌曲
绑定当前歌曲信息
//设置当前播放的音乐
func setCurrentSong(curSong:Song){
currentSong=curSong
photo.image=getImageWithUrl(currentSong.picture)
backgroundImageView.image=photo.image
titleLabel.text=currentSong.title
artistLabel.text=currentSong.artist
playButton.selected=false
playTimeLabel.text="00:00"
self.progressSlider.value=0.0
self.rotationAnimation()
}
//八、*播放音乐
self.audioPlayer.stop()
self.audioPlayer.contentURL=NSURL(string:currentSong.url)
timer?.invalidate()
timer=NSTimer.scheduledTimerWithTimeInterval(0.4, target: self, selector: "updateTime", userInfo: nil, repeats: true)
@IBAction func playButtonClick(sender: UIButton) {
if sender.selected {
//暂停播放
self.audioPlayer.pause()
pauseLayer(photo.layer)
}else{
//开始/继续播放
self.audioPlayer.play()
resumeLayer(photo.layer)
}
sender.selected = !sender.selected
}
//更新播放时间
func updateTime(){
let c=audioPlayer.currentPlaybackTime
// audioPlayer.endPlaybackTime
if c>0.0 {
let t=audioPlayer.duration
let p:CFloat=CFloat(c/t)
progressSlider.value=p;
let all:Int=Int(c)//共多少秒
let m:Int=all % 60//秒
let f:Int=Int(all/60)//分
var time=NSString(format:"%02d:%02d",f,m)
playTimeLabel.text=time
}
}
//九、*当点击播放或暂停时，需要将图片的动画动起来或停止动画
使用到以下两个方法
//停止Layer上面的动画
func pauseLayer(layer:CALayer){
var pausedTime:CFTimeInterval=layer.convertTime(CACurrentMediaTime(), fromLayer: nil)
layer.speed=0.0
layer.timeOffset=pausedTime
}
//继续Layer上面的动画
func resumeLayer(layer:CALayer){
var pausedTime:CFTimeInterval = layer.timeOffset
layer.speed=1.0
layer.timeOffset=0.0
layer.beginTime=0.0
var timeSincePause:CFTimeInterval=layer.convertTime(CACurrentMediaTime(), fromLayer: nil)-pausedTime
layer.beginTime=timeSincePause
}
