由于業(yè)務需求要搞一個類似微信視頻來電规婆，然后手機循環(huán)震動并播放鈴聲的功能泽裳。
網(wǎng)上搜了很多隘谣，沒有得到理想的效果增拥，于是自己寫了一個工具類。

思路：
把震動和音樂拆開來實現(xiàn)寻歧，并給震動設(shè)置了定時器掌栅，每隔一秒調(diào)用；音樂也是码泛，設(shè)置了循環(huán)1000000次猾封。

直接上代碼：

#import "MediaTool.h"
#import <AudioToolbox/AudioToolbox.h>
#import <AVFoundation/AVFoundation.h>

@interface MediaTool ()

@property (nonatomic, strong) NSTimer* shakeTimer;//震動定時器
@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;
}

-(void)shakeOnceTime{
    AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);
}

-(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];
}
