使用AVPlayer播放网络音频简单易行,但是在使用的时候我们需要很多时间的监控处理,这里就需要分装一下,好供我们使用,在不同的地方使用,省去了繁琐的事件监听出,KVO处理不好容易造成多移除崩溃,为移除崩溃,封装到一个类中,统一处理,简单方便,

<以上便是播放的内容,下面介绍如何使用>
先介绍播放点击tableViewCell的播放事件
pragma mark ====点击播放声音=====
首先在需要播放的类这种的viewdidload中先遵循代理
[PlayerSource sharePlayer].delegate = self;
- (void)tapImgaeWithCell:(QuestionTableViewCell *)cell
{
if (IsLogin) {
NSIndexPath *indexPath = [_QuestionTable indexPathForCell:cell];
QuestionStatues *statues = [_DataArray objectAtIndex:indexPath.section];
if (self.index == indexPath.section) {
// [cell setVoicePlayStatues:cq_VoiceplayStatueCancle];
[[PlayerSource sharePlayer]playAudioWithURLString:[detailPublicUrl stringByAppendingString:statues.ansAudio] atindex:indexPath.section];
self.index = NSIntegerMax;
}else
{
[UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
_IndexQuesID = statues.queID;
[PlayerSource sharePlayer].timeText = statues.ansAudioSec;
[[PlayerSource sharePlayer]playAudioWithURLString:[detailPublicUrl stringByAppendingString:statues.ansAudio] atindex:indexPath.section];
[[PlayerSource sharePlayer] setTitleLabel:statues.queTitle timeLabel:statues.ansAudioSec];
self.index = indexPath.section;
}
}else
{
[PublickResource showTipAlertViewWith:self title:@"未登录" message:@"是否立即登录" CancleTitle:@"取消" downTitle:@"立即登录" CancelButton:^{
} DownButton:^{
LoginViewController *log = [[LoginViewController alloc]init];
MKNavigationController *nav = [[MKNavigationController alloc]initWithRootViewController:log];
[self presentViewController:nav animated:YES completion:nil];
}];
}
}
<*代理方法监听的处理*>
-(void)audioPlayerStatuesDidChanged:(cq_audioPayerState)audioPlayer index:(NSInteger)index
{
if (index < _DataArray.count - 1) {
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:index];
QuestionStatues *statues = [_DataArray objectAtIndex:index];
QuestionTableViewCell *voiceMessageCell = [_QuestionTable cellForRowAtIndexPath:indexPath];
VoiceImageStatues voiceStatues;
switch (audioPlayer) {
case cq_audioPayerStateCancle:
voiceStatues = cq_VoiceplayStatueCancle;
_isPlaying = NO;
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
break;
case cq_audioPayerStatePlaying:
voiceStatues = cq_VoiceplayStatuePlaying;
_isPlaying = YES;
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
break;
case cq_audioPayerStateNormal:
_isPlaying = NO;
[self addClickNumberWithID:_IndexQuesID];
NSInteger inter = [statues.clicked integerValue];
inter++;
statues.clicked = [NSString stringWithFormat:@"%ld",(long)inter];
[self.QuestionTable reloadData];
voiceStatues = cq_VoiceplayStatueNormal;
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
default:
break;
}
dispatch_async(dispatch_get_main_queue(), ^{
[voiceMessageCell setVoicePlayStatues:voiceStatues];
});
}
}
<*cell中代理与定义的实现*>
<*cell.h中定义枚举类型*>
typedef NS_ENUM(NSUInteger,VoiceImageStatues){
cq_VoiceplayStatueNormal,/**< 未播放状态*/
cq_VoiceplayStatuePlaying,/**< 未播放状态*/
cq_VoiceplayStatueCancle,/**< 未播放状态*/
};
<*定义代理方法*>
@protocol SelectVoiceImageDelegate <NSObject>
- (void)tapImgaeWithCell:(QuestionTableViewCell *)cell;
@end
<*在cell中声明枚举与代理方法*>
@property (nonatomic ,weak)id<SelectVoiceImageDelegate>delegate;
@property (nonatomic ,assign)VoiceImageStatues VoicePlayStatues;
<介绍使用方法直接播放的方法>
<*同样的需要在类中遵循代理*>
[PlayerSource sharePlayer].delegate = self;
播放方法
[[PlayerSource sharePlayer] playAudioWithWebUrlString: @""];
<*代理时间监听处理*>
