CocoaPods - 用CocoaPods安装

You can install ZLSwipeableView through CocoaPods adding the following to your Podfile:

你可以通过CocoaPods来安装这个文件:

pod 'ZLSwipeableView'

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];
