ユーザーに新しいアナウンスがある場合にステータスバーから下にアニメーション化する UILabel に UITapGestureRecognizer を追加しようとしています。ユーザーがラベルをクリックして直接アナウンスに移動できるようにしたい。UITapGetureRecognizer が機能していません。これが私がやっていることです:
+(void)animateDown:(NSString *)title view:(UIViewController *)view color:(UIColor *)color time:(NSTimeInterval)duration
{
view = view.navigationController.visibleViewController;
if (currentlyDisplayed == NO) {
if (color == nil) color = customGreen;
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0 ,-40, 320, 40)];
label.text = title;
label.font = [UIFont fontWithName:@"STHeitiTC-Medium" size:18];
label.backgroundColor = color;//customBlue;//[UIColor colorWithRed:0.0993145 green:0.0957361 blue:0.562879 alpha:.8f];
label.layer.cornerRadius = 15.0f;
[label setTextAlignment:NSTextAlignmentCenter];
[label setMinimumFontSize:12];
[label setAdjustsFontSizeToFitWidth:YES];
[label sizeToFit];
label.textColor = [UIColor whiteColor];
if ([color isEqual:customBlue]) {
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(onTap:)];
tap.numberOfTapsRequired = 1;
tap.numberOfTouchesRequired = 1;
label.userInteractionEnabled = YES;
[label addGestureRecognizer:tap];
}
[view.view addSubview:label];
[view.view bringSubviewToFront:label];
currentlyDisplayed = YES;
[UIView animateWithDuration:.5f delay:0 options:UIViewAnimationOptionAllowUserInteraction|UIViewAnimationOptionCurveEaseIn animations:^{
label.frame = CGRectMake(0, 0, 320, 40);
}completion:^(BOOL finished) {
CGFloat dur;
if (duration == 0) {
dur = .5f;
}else {
dur = duration;
}
[UIView animateWithDuration:1 delay:dur options:UIViewAnimationOptionAllowUserInteraction|UIViewAnimationOptionCurveEaseOut animations:^{
label.frame = CGRectMake(0,-40,320,40);
}completion:^(BOOL finished) {
if (finished) [label removeFromSuperview];
currentlyDisplayed = NO;
}];
}];
}else {
NSMethodSignature *sig = [[self class] methodSignatureForSelector:@selector(animateDown:view:color:time:)];
NSInvocation *invocation = [NSInvocation invocationWithMethodSignature:sig];
[invocation setSelector:@selector(animateDown:view:color:time:)];
[invocation setTarget:self];
[invocation setArgument:&title atIndex:2];
[invocation setArgument:&view atIndex:3];
[invocation setArgument:&color atIndex:4];
[invocation setArgument:&duration atIndex:5];
[NSTimer scheduledTimerWithTimeInterval:0.5 invocation:invocation repeats:NO];
}
}
- (IBAction)onTap:(UIPanGestureRecognizer *)recognizer {
[[NSNotificationCenter defaultCenter] postNotification:[NSNotification notificationWithName:@"announcementTapped" object:nil]];
NSLog(@"tapped");
}
onTap メソッドは決して呼び出されません....if ステートメントに入ります..画像を参照してください:
