To integrate `CRRefresh` into your Xcode project using Carthage, specify it in your `Cartfile`: 54 | 55 | ``` 56 | github "CRAnimation/CRRefresh" 57 | ``` 58 | 59 | Run `carthage update` to build the framework and drag the built `CRRefresh.framework` (in Carthage/Build/iOS folder) into your Xcode project (Linked Frameworks and Libraries in `Targets`). 60 | 61 | ### Manually 62 | 63 | 1. Download the latest code version . 64 | 2. Open your project in Xcode,drag the `CRRefresh` folder into your project. Make sure to select Copy items when asked if you extracted the code archive outside of your project. 65 | 3. You need it with `import CRRefresh `. 66 | 67 | ## Usage 68 | 69 | ![](CRRefresh3.gif) 70 | 71 | **Add `CRRefresh` to your project** 72 | 73 | ```swift 74 | import CRRefresh 75 | ``` 76 | 77 | **Add pull-to-refresh** 78 | 79 | ```swift 80 | /// animator: your customize animator, default is NormalHeaderAnimator 81 | tableView.cr.addHeadRefresh(animator: NormalHeaderAnimator()) { [weak self] in 82 | /// start refresh 83 | /// Do anything you want... 84 | DispatchQueue.main.asyncAfter(deadline: .now() + 2, execute: { 85 | /// Stop refresh when your job finished, it will reset refresh footer if completion is true 86 | self?.tableView.cr.endHeaderRefresh() 87 | }) 88 | } 89 | /// manual refresh 90 | tableView.cr.beginHeaderRefresh() 91 | ``` 92 | 93 | **Add infinite-scrolling** 94 | 95 | ```swift 96 | /// animator: your customize animator, default is NormalFootAnimator 97 | tableView.cr.addFootRefresh(animator: NormalFootAnimator()) { [weak self] in 98 | /// start refresh 99 | /// Do anything you want... 100 | DispatchQueue.main.asyncAfter(deadline: .now() + 2, execute: { 101 | /// If common end 102 | self?.tableView.cr.endLoadingMore() 103 | /// If no more data 104 | self?.tableView.cr.noticeNoMoreData() 105 | /// Reset no more data 106 | self?.tableView.cr.resetNoMore() 107 | }) 108 | } 109 | ``` 110 | 111 | ## Customize Style 112 | 113 | Customize refresh need conform the **CRRefreshProtocol** protocol. 114 | 115 | ```swift 116 | public protocol CRRefreshProtocol { 117 | /// Customize view 118 | var view: UIView {get} 119 | 120 | /// View insets 121 | var insets: UIEdgeInsets {set get} 122 | 123 | /// The height of the trigger to refresh 124 | var trigger: CGFloat {set get} 125 | 126 | /// The height of the animation is executed 127 | var execute: CGFloat {set get} 128 | 129 | /// Start refresh 130 | mutating func refreshBegin(view: CRRefreshComponent) 131 | 132 | /// End refresh 133 | mutating func refreshEnd(view: CRRefreshComponent, finish: Bool) 134 | 135 | /// Refresh the progress changes 136 | mutating func refresh(view: CRRefreshComponent, progressDidChange progress: CGFloat) 137 | 138 | /// Refresh the state changes 139 | mutating func refresh(view: CRRefreshComponent, stateDidChange state: CRRefreshState) 140 | } 141 | ``` 142 | 143 | ## Remove 144 | 145 | ```swift 146 | tableView.cr.removeFooter() 147 | tableView.cr.removeHeader() 148 | ``` 149 | 150 | ## Contribution 151 | 152 | You are welcome to contribute to the project by forking the repo, modifying the code and opening issues or pull requests. 153 | 154 | ## Contacts 155 | 156 | If you wish to contact me 157 | 158 | - Email: wangchonglei93@icloud.com 159 | - Github: https://github.com/imwcl 160 | - QQ: 631106979 161 | - Dynamic effect study group: 547897182 162 | 163 | ## License 164 | 165 | CRRefresh is released under the [MIT license](LICENSE).
