ios系统自带摇一摇功能实现

第一步:根试图成为第一响应者

- (BOOL)canBecomeFirstResponder{

    return YES;

}

开始摇动

- (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)even

{     NSLog(@"开始摇动手机");

}

结束摇动

- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event {         

//    UIAlertView *yaoyiyao = [[UIAlertView alloc]initWithTitle:@"提示"

message:@"摇动结束" delegate:nil cancelButtonTitle:@"取消" otherButtonTitles:nil, nil];

//    [yaoyiyao show];   

      [self getPhoto];

}

获得截图

- (void)getPhoto{ 

     UIGraphicsBeginImageContext(self.view.bounds.size);   

  [self.view.layer renderInContext:UIGraphicsGetCurrentContext()]; 

   UIImage *image = UIGraphicsGetImageFromCurrentImageContext(); 

   UIGraphicsEndImageContext();

  UIView *subView = [[CustomView alloc]initWithFrame:self.view.frame withImage:image];   [[UIApplication sharedApplication].keyWindow addSubview:subView];

  UIImageWriteToSavedPhotosAlbum(image, self, nil, nil);

}
