###Swipe Programmatically II
You can install ZLSwipeableView through CocoaPods adding the following to your Podfile:
pod 'ZLSwipeableView'
Check out the demo app for an example.
ZLSwipeableView can be added to storyboard or initialized programmatically:
ZLSwipeableView *swipeableView = [[ZLSwipeableView alloc] initWithFrame:self.view.frame];
[self.view addSubview:swipeableView];A ZLSwipeableView must have an object that implements ZLSwipeableViewDelegate to act as a data source. ZLSwipeableView will prefetch three views in advance to animate them.
// required data source
self.swipeableView.dataSource = self;
#pragma mark - ZLSwipeableViewDataSource
- (UIView *)nextViewForSwipeableView:(ZLSwipeableView *)swipeableView {
return [[UIView alloc] init];
}A ZLSwipeableView can have an optional delegate to receive callback.
// 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 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 {
NSLog(@"swiping at location: x %f, y%f", location.x, location.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:
[self.swipeableView swipeTopViewToLeft];
[self.swipeableView swipeTopViewToRight];To discard all views and reload programmatically:
[self.swipeableView discardAllSwipeableViews];
[self.swipeableView loadNextSwipeableViewsIfNeeded];- iOS 7 or higher.
