我找到了我希望在我的应用程序中使用的库XLFORMS 。问题是它没有显示任何行和部分，只是一个空的 tableView。我在我的故事板中创建了一个视图控制器，我在其中删除了视图，因此它只是完全空的视图控制器。然后我将示例代码添加到 ViewDidLoad 方法中，但只是一个空的 tableView？为了显示库中的字段，我还需要什么。

XLFormDescriptor * form;
XLFormSectionDescriptor * section;
XLFormRowDescriptor * row;

form = [XLFormDescriptor formDescriptorWithTitle:@"Add Event"];

// First section
section = [XLFormSectionDescriptor formSection];
[form addFormSection:section];

// Title
row = [XLFormRowDescriptor formRowDescriptorWithTag:@"title" rowType:XLFormRowDescriptorTypeText];
[row.cellConfigAtConfigure setObject:@"Title" forKey:@"textField.placeholder"];
[section addFormRow:row];

// Location
row = [XLFormRowDescriptor formRowDescriptorWithTag:@"location" rowType:XLFormRowDescriptorTypeText];
[row.cellConfigAtConfigure setObject:@"Location" forKey:@"textField.placeholder"];
[section addFormRow:row];

// Second Section
section = [XLFormSectionDescriptor formSection];
[form addFormSection:section];

// All-day
row = [XLFormRowDescriptor formRowDescriptorWithTag:@"all-day" rowType:XLFormRowDescriptorTypeBooleanSwitch title:@"All-day"];
[section addFormRow:row];

// Starts
row = [XLFormRowDescriptor formRowDescriptorWithTag:@"starts" rowType:XLFormRowDescriptorTypeDateTimeInline title:@"Starts"];
row.value = [NSDate dateWithTimeIntervalSinceNow:60*60*24];
[section addFormRow:row];

我也在做同样的事情。代码不应在 ViewDidLoad 中。

因此，在您的 .m 文件中创建一个 void，然后输入代码，使其看起来像这样：

-(void)initform
{

    XLFormSectionDescriptor * section;
    XLFormRowDescriptor * row;

    self.form = [XLFormDescriptor formDescriptorWithTitle:@"Add Event"];

    // First section
    section = [XLFormSectionDescriptor formSection];
    [self.form addFormSection:section];

    // Title
    row = [XLFormRowDescriptor formRowDescriptorWithTag:@"title" rowType:XLFormRowDescriptorTypeText];
    [row.cellConfigAtConfigure setObject:@"Title" forKey:@"textField.placeholder"];
    [section addFormRow:row];

    // Location
    row = [XLFormRowDescriptor formRowDescriptorWithTag:@"location" rowType:XLFormRowDescriptorTypeText];
    [row.cellConfigAtConfigure setObject:@"Location" forKey:@"textField.placeholder"];
    [section addFormRow:row];

    // Second Section
    section = [XLFormSectionDescriptor formSection];
    [self.form addFormSection:section];


// All-day
row = [XLFormRowDescriptor formRowDescriptorWithTag:@"all-day" rowType:XLFormRowDescriptorTypeBooleanSwitch title:@"All-day"];
[section addFormRow:row];


    // Starts
    row = [XLFormRowDescriptor formRowDescriptorWithTag:@"starts" rowType:XLFormRowDescriptorTypeDateTimeInline title:@"Starts"];
    row.value = [NSDate dateWithTimeIntervalSinceNow:60*60*24];
    [section addFormRow:row];

}

除此之外，您还需要确保您的 init 看起来像这样：

- (id)initWithStyle:(UITableViewStyle)style
{
    self = [super initWithStyle:style];
    if (self) {
        // Custom initialization

        [self initform];

    }
    return self;
}

- (id)initWithCoder:(NSCoder *)aDecoder;
{
    self = [super initWithCoder:aDecoder];
    if (self) {
        // Custom initialization

        [self initform];

    }
    return self;
}

希望这对你和我一样有效。祝你好运！:)

您可能错过的另一件事是将您的表格视图（添加到您希望表单呈现的空视图控制器的那个）连接到 XLFormViewController 中的 tableView 出口：

@property IBOutlet UITableView * tableView;

使用 XLFormViewController 而不是 UIViewController 子类化您的 ViewController。创建表单后添加 1 行代码self.form = form。
