ios晃动检测

第一种

1、在AppDelegate.h中进行如下设置：

C代码  

1. - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
2. {
3. application.applicationSupportsShakeToEdit = YES;
4. }

2、在你需要对晃动事件进行处理的ViewController中添加如下代码：

C代码  

1. -(BOOL)canBecomeFirstResponder {
2. return YES;
3. }
4. -(void)viewDidAppear:(BOOL)animated {
5. [super viewDidAppear:animated];
6. [self becomeFirstResponder];
7. }
8. - (void)viewWillDisappear:(BOOL)animated {
9. [self resignFirstResponder];
10. [super viewWillDisappear:animated];
11. }
12. - (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event
13. {
14. if (motion == UIEventSubtypeMotionShake) {
15. NSLog(@"检测到晃动");
16. }
