Question

我在使用具有模态视图切换的摇动手势时遇到问题。第一次进入指定的视图控制器时，摇动手势有效。然而，当我退出并返回时，它没有。我已经实现了can成为第一响应者和viewdidAppear技术，并且控制台使用NSLog条目检测到抖动，但没有任何反应。其他一切似乎都有效，但它不会在第二次观看时发起动摇。

非常感谢任何帮助或见解

请告诉我其他哪些代码会有所帮助 -

-(BOOL)canBecomeFirstResponder {
return YES;}


- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
if ( event.subtype == UIEventSubtypeMotionShake )
{
    // Put in code here to handle shake
    NSLog(@"Shaken");
    time = 9.0;
    timer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(countdown) userInfo:nil repeats:NO];
    myAnimatedView.hidden = NO;
    myAnimatedView2.hidden = NO;
    myAnimatedView3.hidden = NO;
    webViewRandomizer.hidden = YES;
    backToRandomizer.hidden = YES;
    backToRandomizerBG.hidden = YES;
    backRandomizer.hidden = YES;
    forwardRandomizer.hidden = YES;
    backToRandomizerMenu.hidden = YES;
    tweetView.image = [UIImage imageNamed:@"3988567990_60d8da5cdf_o.jpg"];
    [webViewRandomizer resignFirstResponder];
    [self becomeFirstResponder];




    [myAnimatedView setAnimationRepeatCount:6];
    [myAnimatedView2 setAnimationRepeatCount:2];
    [myAnimatedView3 setAnimationRepeatCount:1];
    myAnimatedView.animationDuration = 0.5;
    myAnimatedView2.animationDuration = 3.0;
    myAnimatedView3.animationDuration = 9.0;

    [myAnimatedView startAnimating];
    [myAnimatedView2 startAnimating];
    [myAnimatedView3 startAnimating];



    NSURL *url = [NSURL URLWithString:@"http://historicaltweets.com/"];
    NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
    [webViewRandomizer loadRequest:requestObj];
    [self performSelector:@selector(aShowRandomizer) withObject:nil afterDelay:10.0f];}

if ( [super respondsToSelector:@selector(motionEnded:withEvent:)] ){
    [super motionEnded:motion withEvent:event]; }}

#define kUpdateInterval (1.0f/60.0f)

- (void)viewDidAppear:(BOOL)animated{
UIAccelerometer *accel = [UIAccelerometer sharedAccelerometer];
accel.delegate = self;
accel.updateInterval = kUpdateInterval;
[super viewDidAppear:animated];
[self becomeFirstResponder];}

- (void)viewDidDisappear:(BOOL)animated{
UIAccelerometer *accel = [UIAccelerometer sharedAccelerometer];
accel.delegate = nil;}

-(IBAction)backToRandomizerMenuGo{


[self dismissModalViewControllerAnimated:YES];}
