12 | (It's a component of [YYKit](https://github.com/ibireme/YYKit)) 13 | 14 | Documentation 15 | ============== 16 | 17 | You can build and install docset use `Docset` scheme in Xcode, `appledoc` need to be pre-installed. 18 | Or your can read the [Documentation](http://github.ibireme.com/doc/YYCategories/index.html) online. 19 | 20 | 21 | Installation 22 | ============== 23 | 24 | ### CocoaPods 25 | 26 | 1. Add `pod 'YYCategories'` to your Podfile. 27 | 2. Run `pod install` or `pod update`. 28 | 3. Import \. 29 | 30 | 31 | ### Carthage 32 | 33 | 1. Add `github "ibireme/YYCategories"` to your Cartfile. 34 | 2. Run `carthage update --platform ios` and add the framework to your project. 35 | 3. Import \. 36 | 37 | 38 | ### Manually 39 | 40 | 1. Download all the files in the YYCategories subdirectory. 41 | 2. Add the source files to your Xcode project. 42 | 3. Add `-fno-objc-arc` compiler flag to `NSObject+YYAddForARC.m` and `NSThread+YYAdd.m`. 43 | 4. Link with required frameworks: 44 | * UIKit 45 | * CoreGraphics 46 | * QuartzCore 47 | * Accelerate 48 | * ImageIO 49 | * CoreText 50 | * CoreFoundation 51 | * libz 52 | 5. Import `YYCategories.h`. 53 | 54 | 55 | Documentation 56 | ============== 57 | Full API documentation is available on [CocoaDocs](http://cocoadocs.org/docsets/YYCategories/).
58 | You can also install documentation locally using [appledoc](https://github.com/tomaz/appledoc). 59 | 60 | 61 | Requirements 62 | ============== 63 | This library requires `iOS 6.0+` and `Xcode 8.0+`. 64 | 65 | 66 | Notice 67 | ============== 68 | I want to use the APIs as if it was provided by system, so I don't add prefix in 69 | these categories. This may cause some potential problems（such as conflict with other libraries), so if you just need some pieces of code 70 | in this project, pick them out and don't import the whole library. 71 | 72 | 73 | License 74 | ============== 75 | YYCategories is provided under the MIT license. See LICENSE file for details. 76 | 77 | 78 | 79 | 80 |

85 | (该项目是 [YYKit](https://github.com/ibireme/YYKit) 组件之一) 86 | 87 | 文档 88 | ============== 89 | 90 | 你可以用 `Docset` scheme 来生成文档 (需要预先安装 appledoc)，或者[在线查看](http://github.ibireme.com/doc/YYCategories/index.html)。 91 | 92 | 93 | 安装 94 | ============== 95 | 96 | ### CocoaPods 97 | 98 | 1. 在 Podfile 中添加 `pod 'YYCategories'`。 99 | 2. 执行 `pod install` 或 `pod update`。 100 | 3. 导入 \。 101 | 102 | 103 | ### Carthage 104 | 105 | 1. 在 Cartfile 中添加 `github "ibireme/YYCategories"`。 106 | 2. 执行 `carthage update --platform ios` 并将生成的 framework 添加到你的工程。 107 | 3. 导入 \。 108 | 109 | 110 | ### 手动安装 111 | 112 | 1. 下载 YYCategories 文件夹内的所有内容。 113 | 2. 将 YYCategories 内的源文件添加(拖放)到你的工程。 114 | 3. 为 `NSObject+YYAddForARC.m` 和 `NSThread+YYAdd.m` 添加编译参数 `-fno-objc-arc`。 115 | 4. 链接以下 frameworks: 116 | * UIKit 117 | * CoreGraphics 118 | * QuartzCore 119 | * Accelerate 120 | * ImageIO 121 | * CoreText 122 | * CoreFoundation 123 | * libz 124 | 5. 导入 `YYCategories.h`。 125 | 126 | 127 | 文档 128 | ============== 129 | 你可以在 [CocoaDocs](http://cocoadocs.org/docsets/YYCategories/) 查看在线 API 文档，也可以用 [appledoc](https://github.com/tomaz/appledoc) 本地生成文档。 130 | 131 | 系统要求 132 | ============== 133 | 该项目最低支持 `iOS 6.0` 和 `Xcode 8.0`。 134 | 135 | 136 | 注意 137 | ============== 138 | 我希望调用 API 时，有着和调用系统自带 API 一样的体验，所以我并没有为 Category 方法添加前缀。我已经用工具扫描过这个项目中的 API，确保没有对系统 API 产生影响。我知道没有前缀的 Category 可能会带来麻烦（比如可能和其他某些类库产生冲突），所以如果你只需要其中少量代码，那最好将那段代码取出来，而不是导入整个库。 139 | 140 | 141 | 许可证 142 | ============== 143 | YYCategories 使用 MIT 许可证，详情见 LICENSE 文件。 144 | 145 | 146 | -------------------------------------------------------------------------------- /YYCategories.podspec: -------------------------------------------------------------------------------- 1 | Pod::Spec.new do |s| 2 | s.name = 'YYCategories' 3 | s.summary = 'A manager to get iOS keyboard views, frames and transform.' 4 | s.version = '1.0.4' 5 | s.license = { :type => 'MIT', :file => 'LICENSE' } 6 | s.authors = { 'ibireme' => 'ibireme@gmail.com' } 7 | s.social_media_url = 'http://blog.ibireme.com' 8 | s.homepage = 'https://github.com/ibireme/YYCategories' 9 | s.platform = :ios, '6.0' 10 | s.ios.deployment_target = '6.0' 11 | s.source = { :git => 'https://github.com/ibireme/YYCategories.git', :tag => s.version.to_s } 12 | 13 | s.requires_arc = true 14 | s.source_files = 'YYCategories/**/*.{h,m}' 15 | s.public_header_files = 'YYCategories/**/*.{h}' 16 | 17 | non_arc_files = 'YYCategories/Foundation/NSObject+YYAddForARC.{h,m}', 'YYCategories/Foundation/NSThread+YYAdd.{h,m}' 18 | s.ios.exclude_files = non_arc_files 19 | s.subspec 'no-arc' do |sna| 20 | sna.requires_arc = false 21 | sna.source_files = non_arc_files 22 | end 23 | 24 | s.libraries = 'z' 25 | s.frameworks = 'UIKit', 'CoreFoundation' ,'QuartzCore', 'CoreGraphics', 'CoreImage', 'CoreText', 'ImageIO', 'Accelerate' 26 | 27 | end 28 | -------------------------------------------------------------------------------- /YYCategories/Foundation/NSArray+YYAdd.h: -------------------------------------------------------------------------------- 1 | // 2 | // NSArray+YYAdd.h 3 | // YYCategories 4 | // 5 | // Created by ibireme on 13/4/4. 6 | // Copyright (c) 2015 ibireme. 7 | // 8 | // This source code is licensed under the MIT-style license found in the 9 | // LICENSE file in the root directory of this source tree. 10 | // 11 | 12 | #import 13 | 14 | NS_ASSUME_NONNULL_BEGIN 15 | 16 | /** 17 | Provide some some common method for `NSArray`. 18 | */ 19 | @interface NSArray (YYAdd) 20 | 21 | /** 22 | Creates and returns an array from a specified property list data. 23 | 24 | @param plist A property list data whose root object is an array. 25 | @return A new array created from the plist data, or nil if an error occurs. 26 | */ 27 | + (nullable NSArray *)arrayWithPlistData:(NSData *)plist;
