前段时间封装了简易的自适应表单系统，但是未能一并封装表单编辑以及添加附件功能。今天正好有时间，便把之前遗落的编辑以及附件功能加上，希望能为大家提供思路。

github地址(欢迎Star!)：https://github.com/RockChanel/SelAttachmentForm

由于此版本封装较为仓促，最近针对此版本进行重构，去除了第三方的强依赖，可以根据需求引用，修复部分字段无效的问题，并将可定制化内容接口尽可能统一，详情请移步 iOS 高度封装自适应表单(重构版)

1. 表单条目类别

/** 表单cell类型 */
typedef NS_ENUM(NSInteger, SelwynFormCellType) {
    SelwynFormCellTypeNone = 0,     //default
    SelwynFormCellTypeInput = 1,    //单行或多行输入
    SelwynFormCellTypeTextViewInput = 2,    //包含textView输入
    SelwynFormCellTypeSelect = 3,   //选择
    SelwynFormCellTypeAttachment = 4,   //附件
};

2. 表单条目创建

/**
 快捷创建新增表单条目

 @param formTitle 标题
 @param formDetail 详情
 @param cellType cell类型
 @param keyboardType 键盘类型
 @param editable 是否可编辑
 @param required 是否必填（必选）
 @return 表单条目
 */
NS_INLINE SelwynFormItem *SelwynItemMake(NSString *formTitle, NSString *formDetail, SelwynFormCellType cellType, UIKeyboardType keyboardType, BOOL editable, BOOL required){
    return [SelwynFormHandle itemWithFormTitle:formTitle formDetail:formDetail cellType:cellType keyboardType:keyboardType editable:editable required:required];
}

/**
 快捷创建详情表单条目
 
 @param formTitle 标题
 @param formDetail 详情
 @param cellType cell类型
 @return 表单条目
 */
NS_INLINE SelwynFormItem *SelwynDetailItemMake(NSString *formTitle, NSString *formDetail, SelwynFormCellType cellType){
    return [SelwynFormHandle detailItemWithFormTitle:formTitle formDetail:formDetail cellType:cellType];
}

SelwynFormCellTypeInput:

SelwynFormItem *phoneNumber = SelwynItemMake(@"手机号", @"", SelwynFormCellTypeInput, UIKeyboardTypeNumberPad, YES, YES);
phoneNumber.maxInputLength = 11;    //添加字数限制

SelwynFormCellTypeTextViewInput:

SelwynFormItem *intro = SelwynItemMake(@"个人简介", @"", SelwynFormCellTypeTextViewInput, UIKeyboardTypeDefault, YES, NO);

SelwynFormCellTypeSelect:

SelwynFormItem *gender = SelwynItemMake(@"性别", @"", SelwynFormCellTypeSelect, UIKeyboardTypeDefault, NO, YES);
gender.selectHandle = ^(SelwynFormItem *item) { 
};

SelwynFormCellTypeAttachment:

SelwynFormItem *attachment = SelwynItemMake(@"附件", @"", SelwynFormCellTypeAttachment, UIKeyboardTypeDefault, YES, NO);

3. 编辑

//编辑按钮点击事件
self.editCompletion = ^(){
    [weakSelf.editBtn setTitle:@"完成" forState:UIControlStateNormal];
    name.editable = YES;  //重置可编辑属性
    name.required = YES;    //重置可选必选
    [weakSelf.formTableView reloadData];
};

4. 表单内容校验（可根据需求制定）

校验单个条目内容:

/** 校验表单内容 */
+ (SelwynFormItem *)checkContentWithItem:(SelwynFormItem *)item{
    
    item.formError = @"";
    if (item.required) {
        if (!item.formDetail || [item.formDetail isEqualToString:@""]) {
         
            if (item.formCellType == SelwynFormCellTypeInput || item.formCellType == SelwynFormCellTypeTextViewInput) {
                item.formError = [NSString stringWithFormat:@"请输入%@",item.formTitle];
                
            }else if (item.formCellType == SelwynFormCellTypeSelect){
                item.formError = [NSString stringWithFormat:@"请选择%@",item.formTitle];
            }
        }
    }
    return item;
}

校验整个表单:

/** 校验数据 */ 
- (void)commit{
    for (int sec = 0; sec < self.mutableArray.count; sec++) {
        SelwynFormSectionItem *sectionItem = self.mutableArray[sec];
        
        for (int row = 0; row < sectionItem.cellItems.count; row++) {
            
            SelwynFormItem *rowItem = sectionItem.cellItems[row];
            SelwynFormItem *checkItem = [SelwynFormHandle checkContentWithItem:rowItem];
            if (![checkItem.formError isEqualToString:@""]) {
                UIAlertView *alert = [[UIAlertView alloc]initWithTitle:checkItem.formError message:nil delegate:nil cancelButtonTitle:@"确定" otherButtonTitles: nil];
                [alert show];
                return;
            }
        }
    }
}

通过快捷添加条目的方式构建表单系统，大幅度提升表单开发效率，希望此表单系统能够对大家有所帮助。
