![image](https://github.com/RockChanel/SWGIF/blob/master/SWForm/SWForm.gif) ![image](https://github.com/RockChanel/SWGIF/blob/master/SWForm/SWForm_1.png) `SWForm` 旨在快捷构建表单系统框架，支持大部分表单系统所需条目样式，且包含了图片附件、编辑、新增、详情等功能的拓展. ### Warning 若下载项目之后，运行报错 `incompatible project version`，是由于此项目创建 Xcode 版本为 `9.4.1`。若运行 Xcode 版本低于此版本，解决方法如下： 方法一：更新 Xcode 版本 方法二：右键 `SWFormExample.xcodeproj`， 点击显示包内容，打开 `project.pbxproj` 文件，修改降低 `objectVersion` 即可运行 ### 使用方式 使用 `SWForm` 框架只需将 `SWForm`文件夹导入项目中，将所有可定制化配置的接口都已经统一入口，方便使用者根据自身需求实现定制化功能. 本项目中提供了所有定制化接口的示例 `SWFormDemo`，以作为参考。
`SWForm` 根据需求提供了三个接口文件，以方便使用者实现高度定制化，分别为 `UIImageView+FormImage`、`SWFormImageCell+ImageHandle`、`SWFormHandler`.
`UIImageView+FormImage` 针对表单图片条目图片加载提供接口: ```objective-c - (void)sw_setImageItemWithUrl:(NSURL *)url; ```
`SWFormImageCell+ImageHandle` 提供图片添加接口以及图片预览接口，使用者可以在此接口添加自定义图片选择以及图片预览功能: ```objective-c /** 选择图片数据回调 @param maxImages 最大可选择图片数 @param currentImages 当前选择图片数 @param completion 选择图片数组回调 */ - (void)sw_selectImageWithMaxImages:(NSInteger)maxImages currentImages:(NSInteger)currentImages completion:(void(^)(NSArray *selectImages))completion; /** 图片浏览 @param images 图片数组 @param currentIndex 当前浏览的index */ - (void)sw_photoBrowserWithImages:(NSArray *)images currentIndex:(NSInteger)currentIndex; ```
`SWFormHandler` 为数据校验文件，提供了相机权限、相册权限以及表单空数据校验功能: ```objective-c /** 必选(必填)数据空数据校验，可根据需求定制 @param datas 表单数据源 @param success 必选(必填)数据全部校验成功 @param failure 必选(必填)数据某一项校验失败 */ + (void)sw_checkFormNullDataWithWithDatas:(NSArray *)datas success:(void(^)(void))success failure:(void(^)(NSString *error))failure; /** 校验是否有相机权限 */ + (void)sw_checkCameraAuthorizationStatusWithGrand:(void(^)(BOOL granted))permissionGranted; /** 校验是否有相册权限 */ + (void)sw_checkAlbumAuthorizationStatusWithGrand:(void(^)(BOOL granted))permissionGranted; ``` ================================================ FILE: SWForm/SWForm.bundle/Root.plist ================================================ StringsTable Root PreferenceSpecifiers Type PSGroupSpecifier Title Group Type PSTextFieldSpecifier Title Name Key name_preference DefaultValue IsSecure KeyboardType Alphabet AutocapitalizationType None AutocorrectionType No Type PSToggleSwitchSpecifier Title Enabled Key enabled_preference DefaultValue Type PSSliderSpecifier Key slider_preference DefaultValue 0.5 MinimumValue 0 MaximumValue 1 MinimumValueImage MaximumValueImage ================================================ FILE: SWForm/SWForm.h ================================================ // // SWForm.h // SWFormDemo // // Created by zijin on 2018/5/28. // Copyright © 2018年 selwyn.
