音乐播放器的简单使用:
<1>AVAudioPlayer使用简单方便，但只能播放本地音频，不支持网络连接的播放.
<2>AVPlayer可以播放本地音频也支持网络播放以及视屏播放，但是提供接口较少，处理音频不够灵活.
使用它们都需要导入系统的AVFoundation框架
今天介绍一下AVAudioPlayer的使用
它的使用非常简单直接获取本地音乐路径
NSString *path = [[NSBundle mainBundle] pathForResource:@"本地音乐的名字" ofType:@"后缀"];
NSURL *url = [NSURL fileURLWithPath:path];
AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:nil];
[player play];
这样就可以播放了
但是如果添加上暂停 上一曲 下一曲 歌词 功能 就不能这么简单了由于代码有点多直接上代码了 每一次播放都会创建新的player, 再把上一次的清掉, 并且, 承载音乐播放的VC也不能多次创建
先创建一个Model对象存放本地音乐的数据
Model.h
#import
@interface ModelOfMusic : NSObject
@property (nonatomic, copy) NSString *filename;
@property (nonatomic, copy) NSString *icon;
@property (nonatomic, copy) NSString *name;
@property (nonatomic, copy) NSString *singer;
@property (nonatomic, copy) NSString *singerIcon;
@property (nonatomic, copy) NSString *lrcname;
- (instancetype)initWithDic:(NSDictionary *)dic;
+ (ModelOfMusic *)modelWithDic:(NSDictionary *)dic;
@end
Model.m
#import "ModelOfMusic.h"
@implementation ModelOfMusic
- (instancetype)initWithDic:(NSDictionary *)dic {
self = [super init];
if (self) {
[self setValuesForKeysWithDictionary:dic];
}
return self;
}
+ (ModelOfMusic *)modelWithDic:(NSDictionary *)dic {
return [[self alloc] initWithDic:dic];
}
- (void)setValue:(id)value forUndefinedKey:(NSString *)key {
}
- (id)valueForUndefinedKey:(NSString *)key {
return nil;
}
@end
还要创建管理音乐数据的类
