Usage - 使用
Check out the demo app for an example.
你可以在示例中查看使用方法.
ZLSwipeableView can be added to storyboard or instantiated programmatically:
ZLSwipebleView可以直接在storyboard中使用或者是直接实例化出来:
ZLSwipeableView *swipeableView = [[ZLSwipeableView alloc] initWithFrame:self.view.frame];
[self.view addSubview:swipeableView];
A ZLSwipeableView must have an object that implements ZLSwipeableViewDataSource to act as a data source. ZLSwipeableView will prefetch three views in advance to animate them.
ZLSwipeableView必须有一个对象,这个对象是作为data source来使用的.
// required data source
self.swipeableView.dataSource = self;
#pragma mark - ZLSwipeableViewDataSource
- (UIView *)nextViewForSwipeableView:(ZLSwipeableView *)swipeableView {
return [[UIView alloc] init];
}
The demo app includes examples of both creating views programmatically and loading views from Xib files that use Auto Layout.
A ZLSwipeableView can have an optional delegate to receive callback.
demo中已经包含了通过Xib和普通模式创建出来view的例子,ZLSwipeableView能够通过可选的协议来接受回调.
// optional delegate
self.swipeableView.delegate = self;
#pragma mark - ZLSwipeableViewDelegate
- (void)swipeableView:(ZLSwipeableView *)swipeableView didSwipeLeft:(UIView *)view {
NSLog(@"did swipe left"); } - (void)swipeableView:(ZLSwipeableView *)swipeableView didSwipeRight:(UIView *)view { NSLog(@"did swipe right"); } - (void)swipeableView:(ZLSwipeableView *)swipeableView didCancelSwipe:(UIView *)view { NSLog(@"did cancel swipe"); } - (void)swipeableView:(ZLSwipeableView *)swipeableView didStartSwipingView:(UIView *)view atLocation:(CGPoint)location { NSLog(@"did start swiping at location: x %f, y%f", location.x, location.y); } - (void)swipeableView:(ZLSwipeableView *)swipeableView swipingView:(UIView *)view atLocation:(CGPoint)location translation:(CGPoint)translation { NSLog(@"swiping at location: x %f, y %f, translation: x %f, y %f", location.x, location.y, translation.x, translation.y); } - (void)swipeableView:(ZLSwipeableView *)swipeableView didEndSwipingView:(UIView *)view atLocation:(CGPoint)location { NSLog(@"did start swiping at location: x %f, y%f", location.x, location.y); }
To swipe the top view programmatically:
滑动顶部的view:
[self.swipeableView swipeTopViewToLeft];
[self.swipeableView swipeTopViewToRight];
To discard all views and reload programmatically:
弃用所有的view,然后重新加载:
[self.swipeableView discardAllSwipeableViews];
[self.swipeableView loadNextSwipeableViewsIfNeeded];
Requirements - 需要的环境
