18 | 19 | `TXScrollLabelView` is an iOS lightweight library that can displays adverts or boardcast e.g. with an custom view. 20 | 21 | > [中文介绍](http://www.jianshu.com/p/8f1f1b1ee814) 22 | 23 | ![x-scroll-label-view](https://tingxins.com/assets/histories/TXScrollLabelView/master/x-scroll-label-view.gif) 24 | 25 | ## Support what kinds of scrollType 26 | 27 | - **TXScrollLabelViewTypeLeftRight** : scrolling from right to left, and cycle all contents(`scrollTitle`) in a single line. 28 | 29 | 30 | - **TXScrollLabelViewTypeUpDown**: scrolling from bottom to top, and cycle all contents. 31 | 32 | 33 | - **TXScrollLabelViewTypeFlipRepeat**: scrolling from bottom to top, and cycle the first line of your contents. 34 | 35 | 36 | - **TXScrollLabelViewTypeFlipNoRepeat**: scrolling from bottom to top, and cycle all contents with a line once times. 37 | 38 | And `scrollVelocity` property now supports all above enum of `TXScrollLabelViewType`, just enjoy it! 39 | 40 | ## Installation 41 | 42 | There are three ways to use TXScrollLabelView in your project: 43 | 44 | * Using CocoaPods 45 | 46 | * Manual 47 | 48 | * Using Carthage 49 | 50 | ### CocoaPods 51 | 52 | CocoaPods is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries in your projects. 53 | 54 | **Podfile** 55 | 56 | platform :ios, '7.0' 57 | pod 'TXScrollLabelView' 58 | 59 | ### Manual 60 | 61 | Download repo's zip, and just drag **ALL** files in the TXScrollLabelView folder to your projects. Import header file when you are using: 62 | 63 | #import "TXScrollLabelView.h" 64 | 65 | ### Carthage 66 | 67 | [Carthage](https://github.com/Carthage/Carthage) is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks. 68 | 69 | You can install Carthage with [Homebrew](http://brew.sh/) using the following command: 70 | 71 | $ brew update 72 | $ brew install carthage 73 | 74 | To integrate **TXScrollLableView** into your Xcode project using Carthage, specify it in your Cartfile: 75 | 76 | github "tingxins/TXScrollLableView" 77 | 78 | Run carthage to build the frameworks and drag the framework into your Xcode project. 79 | 80 | ## Usage 81 | 82 | Now, TXScrollLabelView supports both **array & string**. just enjoy it. 👀 83 | 84 | ### Example 85 | 86 | **Objective-C :** 87 | 88 | /** Step1: 滚动文字 */ 89 | NSString *scrollTitle = @"xxxxxx"; 90 | 91 | /** Step2: 创建 ScrollLabelView */ 92 | TXScrollLabelView *scrollLabelView = [TXScrollLabelView scrollWithTitle:scrollTitle type:TXScrollLabelViewTypeFlipNoRepeat velocity:velocity options:UIViewAnimationOptionCurveEaseInOut]; 93 | 94 | /** Step3: 设置代理进行回调(Optional) */ 95 | scrollLabelView.scrollLabelViewDelegate = self; 96 | 97 | /** Step4: 布局(Required) */ 98 | scrollLabelView.frame = CGRectMake(50, 100, 300, 30); 99 | [self.view addSubview:scrollLabelView]; 100 | 101 | /** Step5: 开始滚动(Start scrolling!) */ 102 | [scrollLabelView beginScrolling]; 103 | 104 | 105 | You can running **TXScrollLabelViewDemo** for more details. 106 | 107 | **Swift :** Producting.([**Swift-version**](https://github.com/tingxins/ScrollLabelView)) 108 | 109 | ### Delegate Method 110 | 111 | Tap Gesture callback. 112 | 113 | ``` 114 | 115 | - (void)scrollLabelView:(TXScrollLabelView *)scrollLabelView didClickWithText:(NSString *)text atIndex:(NSInteger)index; 116 | 117 | ``` 118 | 119 | ## Communication 120 | 121 | Absolutely，you can contribute to this project all the time if you want to. 122 | 123 | - If you **need help or ask general question**, just [**@tingxins**](http://weibo.com/tingxins) in `Weibo` or `Twitter`, ofcourse, you can access to my [**blog**](https://tingxins.com). 124 | 125 | - If you **found a bug**, just open an issue. 126 | 127 | - If you **have a feature request**, just open an issue. 128 | 129 | - If you **want to contribute**, fork this repository, and then submit a pull request. 130 | 131 | ## License 132 | 133 | `TXScrollLabelView` is available under the MIT license.
