You can design your own text suggestion display controller to work with it. 22 | 23 | ##What's inside? 24 | 25 | `WUTextSuggestion` is consists of two parts. 26 | 27 | ####WUTextSuggestionController 28 | 29 | `WUTextSuggestionController` provides the text searching and checking function. It tells you when and how you should give your user text suggestions. 30 | 31 | ####WUTextSuggestionDisplayController 32 | 33 | `WUTextSuggestionDisplayController`, a text suggestion display controller based on `UIMenuController`. It asks it's `dataSource` for the text suggestions, and display them beautifully on the screen. 34 | 35 | ##Usage 36 | 37 | ### A. The simple way, use WUTextSuggestionDisplayController. 38 | 39 | Using `WUTextSuggestionDisplayController` to display text suggestions. 40 | 41 | 1. Setup. 42 | 43 | ``` 44 | //Create a WUTextSuggestionDisplayController and assign the dataSource. 45 | WUTextSuggestionDisplayController *suggestionDisplayController = [[WUTextSuggestionDisplayController alloc] init]; 46 | suggestionDisplayController.dataSource = self; 47 | 48 | //Create a WUTextSuggestionController with a textView and the suggestionDisplayController you just created. 49 | WUTextSuggestionController *suggestionController = [[WUTextSuggestionController alloc] initWithTextView:self.textView suggestionDisplayController:suggestionDisplayController]; 50 | 51 | //Set the suggestion type 52 | suggestionController.suggestionType = WUTextSuggestionTypeAt | WUTextSuggestionTypeHashTag; 53 | 54 | ``` 55 | 56 | 2. Provide the suggestions. 57 | 58 | You need to provide the text suggestions based on `suggestionType` and `suggestionQuery`. 59 | 60 | When a user typed `@na`, the `suggestionType` will be `WUTextSuggestionTypeAt`, and the `suggestionQuery` will be `na`. 61 | 62 | You need to wrap the suggestions in `WUTextSuggestionItem` objects, return an array of WUTextSuggestionItem. 63 | 64 | A `WUTextSuggestionItem` has a `title` and a `customActionBlock`. 65 | 66 | `title` is the suggesting text. 67 | 68 | `customActionBlock`, if assigned, will be executed after user tapped that text suggestion. 69 | 70 | ``` 71 | //WUTextSuggestionDisplayControllerDataSource 72 | 73 | - (NSArray *)textSuggestionDisplayController:(WUTextSuggestionDisplayController *)textSuggestionDisplayController suggestionDisplayItemsForSuggestionType:(WUTextSuggestionType)suggestionType query:(NSString *)suggestionQuery 74 | { 75 | //return an array of WUTextSuggestionItem. 76 | } 77 | 78 | ``` 79 | 80 | You can also chose to use `-textSuggestionDisplayController:suggestionDisplayItemsForSuggestionType:query:callback:` for async data loading. 81 | 82 | 3. Done. **There's a demo project `WUTextSuggestionDemo`**. 83 | 84 | ### B. Working with your custom text suggestion display controller. 85 | 86 | 1. You need to use `- initWithTextView:` to create an instance of `WUTextSuggestionController`. 87 | 88 | 2. The `textView` will hold a strong pointer to the `textSuggestionController` which can be acquired using `textSuggestionController` property of the `textView`. 89 | 90 | 3. Set the `suggestionType` property of the `textSuggestionController`. 91 | 92 | 4. Listen to the callback and present your custom text suggestion view. 93 | 94 | 95 | ``` 96 | //1. 97 | WUTextSuggestionController *suggestionController = [[WUTextSuggestionController alloc] initWithTextView:self.textView]; 98 | 99 | //3. 100 | suggestionController.suggestionType = WUTextSuggestionTypeAt | WUTextSuggestionTypeHashTag; 101 | 102 | //4. 103 | [suggestionController setShouldBeginSuggestingBlock:^{ 104 | //"@" or "#" detected. You should prepare your text suggestion view. 105 | }]; 106 | [suggestionController setShouldReloadSuggestionsBlock:^(WUTextSuggestionType type, NSString *query, NSRange range) { 107 | //User typed something after the "@" or "#", you should show your text suggestion view with suggestions. 108 | }]; 109 | [suggestionController setShouldEndSuggestingBlock:^{ 110 | //Suggesting end. You should hide your text suggestion view. 111 | }]; 112 | 113 | ``` 114 | 115 | ##Roadmap 116 | 117 | - UITextField support. 118 | 119 | ##Requirements 120 | 121 | - Automatic Reference Counting (ARC) 122 | - iOS 5.0+ 123 | - Xcode 4.5+ 124 | 125 | ##Contributing 126 | 127 | If you find a bug and know exactly how to fix it, please open a pull request. 128 | 129 | If you can't make the change yourself, please open an issue after making sure that one isn't already logged. 130 | 131 | ##License 132 | 133 | The MIT license, as aways. 134 | -------------------------------------------------------------------------------- /Screenshots/screenshot.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/YuAo/WUTextSuggestion/3884f37e2028735ca738d3bc24952066b9b1cdb1/Screenshots/screenshot.png -------------------------------------------------------------------------------- /WUTextSuggestion.podspec: -------------------------------------------------------------------------------- 1 | Pod::Spec.new do |s| 2 | s.name = "WUTextSuggestion" 3 | s.version = "0.2.0" 4 | s.summary = "A text suggestion toolkit for iOS." 5 | s.description = <<-DESC 6 | `WUTextSuggestion` aims to be a full featured text suggestion toolkit for iOS. 7 | 8 | It can easily be integrated in your project with only couple lines of code. 9 | 10 | It allows you to load text suggestions asynchronously from a remote server. 11 | 12 | It is fully customizable.
