iOS摇一摇的使用

Sian

一、实现系统自带的motionBegan方法

[Objective-C] 纯文本查看 复制代码

/// 开始
- (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event NS_AVAILABLE_IOS(3_0);
/// 结束
- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event NS_AVAILABLE_IOS(3_0);
/// 取消
- (void)motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)event NS_AVAILABLE_IOS(3_0);

假如程序不响应此方法，再实现以下方法：

[Objective-C] 纯文本查看 复制代码

- (BOOL)canBecomeFirstResponder
{
    return YES;
}

二、motionBegan+通知的方法（建议）
1.在Appdelegate里写motionBegan方法

[Objective-C] 纯文本查看 复制代码

-(void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
    [[NSNotificationCenter defaultCenter] postNotificationName:@"SAMotionBegan" object:@(motion)];
}

2.在需要接收通知的页面添加通知

[Objective-C] 纯文本查看 复制代码

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    [SANotice addObserver:self selector:@selector(shake) name:@"SAMotionBegan" object:nil];
}

- (void)shake
{
    SALog(@"摇一摇开始...");
}
