iOS震动反馈

长震动

AudioServicesPlaySystemSoundWithCompletion(kSystemSoundID_Vibrate, nil);
//未来即将弃用
//AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);  //4095

支持iPhone基本机型，支持iOS9
注：用户在“系统设置”中关闭了振动功能，此震动会失效。

短震动一

// 普通短震，3D Touch 中 Peek 震动反馈
AudioServicesPlaySystemSoundWithCompletion(1519, nil);
// 普通短震，3D Touch 中 Pop 震动反馈
AudioServicesPlaySystemSoundWithCompletion(1520, nil);
// 连续三次短震
AudioServicesPlaySystemSoundWithCompletion(1521, nil);
// 'Try Again' feedback (week boom then strong boom)
AudioServicesPlaySystemSoundWithCompletion(1102, nil);

支持iPhone 6s及其以上机型
注：可能会涉及私有属性，影响iOS审核，请谨慎选择。
关于是否调用了私有 API，也有一些讨论，可以查看这里。

关于自定义震动

如果你想自定义震动，或者想在iPhone基本机型，iOS9系统下实现短震，可以尝试使用私有API来实现。
但是同样的也要承受App审核被拒的风险。

NSMutableDictionary* dict = [NSMutableDictionary dictionary];
NSMutableArray* arr = [NSMutableArray array ];

[arr addObject:[NSNumber numberWithBool:YES]]; //vibrate for 2000ms
[arr addObject:[NSNumber numberWithInt:2000]];

[arr addObject:[NSNumber numberWithBool:NO]];  //stop for 1000ms
[arr addObject:[NSNumber numberWithInt:1000]];

[arr addObject:[NSNumber numberWithBool:YES]];  //vibrate for 1000ms
[arr addObject:[NSNumber numberWithInt:1000]];

[arr addObject:[NSNumber numberWithBool:NO]];    //stop for 500ms
[arr addObject:[NSNumber numberWithInt:500]];

[dict setObject:arr forKey:@"VibePattern"];
[dict setObject:[NSNumber numberWithInt:1] forKey:@"Intensity"];

AudioServicesPlaySystemSoundWithVibration(4095,nil,dict);
AudioServicesStopSystemSound();
