由于业务需求要搞一个类似微信视频来电，然后手机循环震动并播放铃声的功能。
网上搜了很多，没有得到理想的效果，于是自己写了一个工具类。
思路：
把震动和音乐拆开来实现，并给震动设置了定时器，每隔一秒调用；音乐也是，设置了循环1000000次。
直接上代码：
#import "MediaTool.h"
#import <AudioToolbox/AudioToolbox.h>
#import <AVFoundation/AVFoundation.h>
@interface MediaTool ()
@property (nonatomic, strong) NSTimer* shakeTimer;//震动定时器
@property (nonatomic, strong) AVAudioPlayer* player;
@end
@implementation MediaTool
+(instancetype)shareInstance{
static MediaTool* tool = nil;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
tool = [[MediaTool alloc]init];
});
return tool;
}
/**
震动一次
*/
-(void)shakeOnceTime{
AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);
}
/**
开始震动和播放音乐
@param soundName 音乐文件路径
*/
-(void)beginShakeAndSound:(NSString *)soundName{
self.shakeTimer = [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(shakePhone) userInfo:nil repeats:YES];
[[NSRunLoop currentRunLoop] addTimer:self.shakeTimer forMode:NSDefaultRunLoopMode];
NSError *error;
NSString *path = [[NSBundle mainBundle] pathForResource:soundName ofType:nil];
if (![[NSFileManager defaultManager] fileExistsAtPath:path]) {
return;
}
SystemSoundID soundID = 0;
CFURLRef urlRef = (__bridge CFURLRef)([NSURL fileURLWithPath:path]);
AudioServicesCreateSystemSoundID(urlRef, &soundID);
self.player = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:&error];
if (!self.player) {
NSLog(@"Error: %@", [error localizedDescription]);
return;
}
[self.player setNumberOfLoops:1000000];
[self.player prepareToPlay];
[self.player play];
}
/**
停止震动和音乐
*/
-(void)stopShakeAndSound{
[_player stop];
//停止前手动出发震动一下
[self shakePhone];
[_shakeTimer invalidate];
}
-(void)shakePhone{
AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);
}
-(void)dealloc{
}
