实用知识：摇一摇功能的方法使用（真简单？？）

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

// 开始摇一摇
- (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
NSLog(@"开始摇一摇");
}

// 结束摇一摇
- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
NSLog(@"结束摇一摇");
}

// 摇一摇被取消
- (void)motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
NSLog(@"取消摇一摇");
}

@end
