這個(gè)播放界面寫(xiě)的, 我真的是坎坷曲折,里面的功能,繁瑣復(fù)雜,改了一遍又一遍,測(cè)試了一遍又一遍,最后也終于是成型了
其實(shí)大家很多人都寫(xiě)過(guò)播放頁(yè),但是功能是否完備就成了各種播放頁(yè)對(duì)比鮮明的因素
好的播放頁(yè),應(yīng)該具備的功能: 跳轉(zhuǎn), 播放, 暫停, 重置, 同首歌曲不重置, 收藏, 分享, 歌詞聯(lián)動(dòng), 耳機(jī)線控,上一曲, 下一曲, 列表循環(huán), 單曲循環(huán), 隨機(jī)播放, 以及播放列表的一系列功能,
當(dāng)然了,我的player也不算是最完善的

靜態(tài)變量創(chuàng)建player, 以及播放音樂(lè)所需用的model
static ALPS_PlayMusicTool *player;
static ALPS_PlayMusicModel *playingMusicModel;
@interface ALPS_PlayMusicTool()
/**

@property (nonatomic, retain) AVPlayerItem *currentItem;

單例初始化播放器
+ (instancetype)manager
{
static dispatch_once_t once_Token;
dispatch_once(&once_Token, ^{
//初始化播放器
player = [[ALPS_PlayMusicTool alloc] init];
});
return player;
}
#pragma mark -- 初始化方法(僅運(yùn)行一次)
- (id)init
{
self = [super init];
if (self)
{
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
self.player = [AVPlayer playerWithPlayerItem:self.currentItem];
self.player.volume = 0.4;
});
isPlaying = NO;
}
return self;
}
播放/暫停音樂(lè)的方法
#pragma mark -- 播放音樂(lè)
- (void)playCurrentMusic
{
if (isPlaying)
{
return;
}
if (!isPlaying)
{
[self.player replaceCurrentItemWithPlayerItem:self.currentItem];
[self.player play];
isPlaying = YES;
}
}
#pragma mark -- 暫停音樂(lè)
- (void)pauseCurrentMusic
{
if (isPlaying)
{
[self.player pause];
isPlaying = NO;
return;
}
if (!isPlaying)
{
return;
}
}
獲取當(dāng)前音樂(lè)的播放時(shí)間
#pragma mark -- 獲取播放時(shí)長(zhǎng)
- (NSString *)getCurrentTime
{
CGFloat currentTime = CMTimeGetSeconds([self.player currentTime]);
int minutes = (int)currentTime / 60;
int seconds = (int)currentTime - minutes * 60;
NSString *timeString;
if (minutes >= 0 && seconds >= 0)
{
if (minutes < 1 && seconds < 10)
{
timeString = [NSString stringWithFormat:@"00:0%d", seconds];
}
else if (minutes <= 1 && seconds >= 10)
{
timeString = [NSString stringWithFormat:@"00:%d", seconds];
}
else if (minutes >= 1 && seconds < 10)
{
timeString = [NSString stringWithFormat:@"%d:0%d", minutes, seconds];
}
else if (minutes >= 1 && seconds >= 10)
{
timeString = [NSString stringWithFormat:@"%d:%d", minutes, seconds];
}
}
else
{
timeString = @"00:00";
}
return timeString;
}
model的set方法來(lái)進(jìn)行當(dāng)前播放歌曲的置換
- (void)setModel:(ALPS_PlayMusicModel *)model
{
isPlaying = YES;
if ([playingMusicModel.playUrl64 isEqualToString:model.playUrl64])
{
return;
}
else
{
self.currentItem = [AVPlayerItem playerItemWithURL:[NSURL URLWithString:model.playUrl64]];
[self.player replaceCurrentItemWithPlayerItem:self.currentItem];
[self.player play];
playingMusicModel = model;
}
}
比較low的方法, 根據(jù)url來(lái)播放
- (void)playRadioWithURL:(NSString *)urlString
{
self.currentItem = [AVPlayerItem playerItemWithURL:[NSURL URLWithString:urlString]];
[self.player replaceCurrentItemWithPlayerItem:self.currentItem];
[self.player play];
isPlaying = YES;
}
播放界面呢, 永遠(yuǎn)沒(méi)有最完善, 只有更完善, 更多的功能, 基本的方法呢, 我介紹給大家, 剩下的就是各家所長(zhǎng)隨機(jī)發(fā)揮了
我所寫(xiě)的這點(diǎn)東西是完全不夠的, 當(dāng)然了UI方面我相信各位大牛小白也都可以, 主要的就是這個(gè)邏輯思維
有一點(diǎn)提醒給大家. 如果大家運(yùn)用avplayer時(shí)候想寫(xiě) 聽(tīng)歌曲和聽(tīng)廣播聯(lián)合的app的話, 盡量使用一個(gè)avplayer然后在播放里面添加判斷, 雖然, 判斷會(huì)很麻煩, 但是如果使用兩個(gè)avplayer會(huì)CPU爆炸的, 相信我
