ios - 向 iCarousel 项目添加自定义手势
<p><p>您好<br/>我已经使用 Xcode 有一段时间了，并且现在使用了很多次 <code>UIGestureRecognizers</code>。目前我正在开发一个需要轮播的 iPad 应用程序，所以有什么比使用 iCarousel 更好，因为我已经遇到过它，我认为它很棒。 <br/>
我在向轮播项目添加 <code>UISwipeGestureRecognizer</code> 时遇到了一些问题(我会用它来删除“刷过”项目)。看起来很容易，但看起来 <code>UIGestureRecognizer</code> 不存在，但如果打印 view.recognizer 我可以看到它实际上存在。我错过了什么？
对于任何语言错误，我们深表歉意!</p>

<pre><code>- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view
{
UILabel *nameLabel = nil;
UILabel *notesLabel = nil;
UIImageView *icon1 = nil;
UIImageView *icon2 = nil;
Notebook *referenceNotebook = ;
//create new view if no view is available for recycling
if (view == nil)
{
view = [ initWithFrame:CGRectMake(0, 0, 250.0f, 373.0f)];
((UIImageView *)view).image = ;
view.contentMode = UIViewContentModeCenter;
CGPoint startingPoint = view.frame.origin;
CGSize startingSize = view.frame.size;
nameLabel = [ initWithFrame:CGRectMake(startingPoint.x, startingPoint.y + 60, startingSize.width, 100)];
nameLabel.backgroundColor = ;
nameLabel.textAlignment = NSTextAlignmentCenter;
nameLabel.font = ;
nameLabel.tag = 1;
;
notesLabel = [initWithFrame:CGRectMake(startingPoint.x, startingPoint.y + 95, startingSize.width, 100)];
notesLabel.backgroundColor = ;
notesLabel.textAlignment = NSTextAlignmentCenter;
notesLabel.font = ;
;
icon1 = [ initWithFrame:CGRectMake(startingPoint.x + 105, startingPoint.y + 18, 40, 40)];
icon1.image = ;
;
icon2 = [ initWithFrame:CGRectMake(startingPoint.x + 105, startingPoint.y + 320, 40, 40)];
icon2.image = ;
;
//UIView *swipeView = [ initWithFrame:CGRectMake(startingPoint.x, startingPoint.y, startingSize.width, startingSize.height)];
//swipeView.backgroundColor = ;
//UISwipeGestureRecognizer *swipeRecognizer = [ initWithTarget:self action:@selector(carouselSwipewipeHandler:)];
//;
// ;
//;
}
else
{
//get a reference to the label in the recycled view
nameLabel = (UILabel *);
}
nameLabel.text = referenceNotebook.name;
notesLabel.text = @"n note";
UISwipeGestureRecognizer *swipeRecognizer = [ initWithTarget:self action:@selector(carouselSwipewipeHandler:)];
;
;
view.tag = index;
NSLog(@"gesture recogs: %@", view.gestureRecognizers);
return view;
}

有人知道我做错了什么吗？

<p><p>默认情况下，任何时候只能激活一种手势，并且轮播在内部使用一种手势进行滚动。因此，如果您想使用其他手势，您需要为您的手势和轮播手势添加一个代理，以便您可以使它们工作 <a href="https://developer.apple.com/library/ios/documentation/uikit/reference/UIGestureRecognizerDelegate_Protocol/Reference/Reference.html#jumpTo_5" rel="noreferrer noopener nofollow">simultaneously</a> .</p></p>
