iOS开发之XLForm的使用方法-移动开发

这篇文章主要介绍了iOS开发之XLForm的使用方法，小编觉得挺不错的，现在分享给大家，也给大家做个参考。一起跟随小编过来看看吧

在iOS开发中，开发"表单"界面，字段稍微多一点的一般都用UITableView来做，而XLForm就是这样一个框架，它是创建动态表格视图最牛逼的iOS库，用它实现表单功能，非常简单，省心省力。但是很可惜，搜索了很多文章都只是翻译官方文档，很多人在使用该库的时候可能都被官方文档带走远了，不知道如何具体使用。正好最近也要用到这个库，所以写个入门使用文章供大家参考。

一、导入项目

使用CocoaPods或者手动导入库文件，本人选择直接导入项目源文件的方式。

二、改造表单ViewController

让ViewController继承自XLFormViewController,并重写下面的两个方法


@interface OneViewController : XLFormViewController

@end


@implementation OneViewController

- (instancetype)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
  self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
  if (self){
    [self initializeForm];
  }
  return self;
}

- (id)initWithCoder:(NSCoder *)aDecoder {
  self = [super initWithCoder:aDecoder];
  if (self){
    [self initializeForm];
  }
  return self;
}
@end

三、构造表单


- (void)initializeForm {
  
  // 设置是否显示Cell之间分界线
  //self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
  // 设置Section的高度
  self.tableView.sectionHeaderHeight = 30;
  
  XLFormDescriptor * form;//form，一个表单只有一个
  XLFormSectionDescriptor * section;//section，一个表单可能有多个
  XLFormRowDescriptor * row; //row，每个section可能有多个row
  
  // Form
  form = [XLFormDescriptor formDescriptor];

  
  // First section
  section = [XLFormSectionDescriptor formSection];
  section.title = @"用户";
  [form addFormSection:section];
  // 普通文本
  row = [XLFormRowDescriptor formRowDescriptorWithTag:@"username" rowType:XLFormRowDescriptorTypeText];
  // 设置placeholder
  [row.cellConfig setObject:@"用户名" forKey:@"textField.placeholder"];
  // 设置文本颜色
  [row.cellConfig setObject:[UIColor redColor] forKey:@"textField.textColor"];
  [section addFormRow:row];
  // 密码
  row = [XLFormRowDescriptor formRowDescriptorWithTag:@"password" rowType:XLFormRowDescriptorTypePassword];
  // 设置placeholder的颜色
  NSAttributedString *attrString = [[NSAttributedString alloc] initWithString:@"密码" attributes:
                   @{NSForegroundColorAttributeName:[UIColor greenColor],
                    }];
  [row.cellConfig setObject:attrString forKey:@"textField.attributedPlaceholder"];
  [section addFormRow:row];
  
  
  
  // Second Section
  section = [XLFormSectionDescriptor formSection];
  section.title = @"日期";
  [form addFormSection:section];
  // 日期选择器
  row = [XLFormRowDescriptor formRowDescriptorWithTag:@"birthday" rowType:XLFormRowDescriptorTypeDate title:@"出生日期"];
  row.value = [NSDate dateWithTimeIntervalSinceNow:60*60*24];
  [section addFormRow:row];
  
  
  
   // Third Section
  section = [XLFormSectionDescriptor formSection];
  section.title = @"头像";
  [form addFormSection:section];
  // 图片选择
  row = [XLFormRowDescriptor formRowDescriptorWithTag:@"userpic" rowType:XLFormRowDescriptorTypeImage];
  [section addFormRow:row];
  
  
  
  // Fourth Section
  section = [XLFormSectionDescriptor formSection];
  section.title = @"选择器";
  [form addFormSection:section];
  // 选择器
  row = [XLFormRowDescriptor formRowDescriptorWithTag:@"sex" rowType:XLFormRowDescriptorTypeSelectorPush];
  row.noValueDisplayText = @"暂无";
  row.selectorTitle = @"性别选择";
  row.selectorOptions = @[@"男",@"女",@"其他"];
  row.title = @"性别";
  [row.cellConfigForSelector setObject:[UIColor redColor] forKey:@"textLabel.textColor"];
  [row.cellConfigForSelector setObject:[UIColor greenColor] forKey:@"detailTextLabel.textColor"];
  [section addFormRow:row];
  
  
  
  // Fifth Section
  section = [XLFormSectionDescriptor formSection];
  section.title = @"加固";
  [form addFormSection:section];
  // 开关
  row = [XLFormRowDescriptor formRowDescriptorWithTag:@"enforce" rowType:XLFormRowDescriptorTypeBooleanSwitch title:@"加固"];
  [section addFormRow:row];
  
  
  // Sixth Section
  section = [XLFormSectionDescriptor formSection];
  [form addFormSection:section];
  // 按钮
  row = [XLFormRowDescriptor formRowDescriptorWithTag:@"conform" rowType:XLFormRowDescriptorTypeButton];
  row.title = @"确定";
  [section addFormRow:row];
  

  self.form = form;
}

-(void)didSelectFormRow:(XLFormRowDescriptor *)formRow{

  // 判断是不是点击了确定按钮
  if([formRow.tag isEqualToString:@"conform"] && formRow.rowType == XLFormRowDescriptorTypeButton){

    //获取表单所有到的值
    NSDictionary *values = [self formValues];

    NSLog(@"%@", values);

  }
  
  [super didSelectFormRow:formRow];

}

//重写改该方法 上面的方法就不会调用了
//-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
//
//  NSLog(@"%s", __func__);
//
/
