自定义单元格未重绘 Three20

我有一个尴尬的问题，调用 [self invalidateModel]; 不会重绘我的自定义单元格。

我有一个带有操作表的 TTTableViewController，允许在按下时命令表格的显示。数据正确重绘，但单元格未重绘。反而有重用。

为了更好地说明：
在我的 CustomTableItemCell 类的 - (void)layoutSubviews { 中，我有这个：

if (bookmarked) {
        UIImage *bookmark = [UIImage imageNamed: @"[email protected]"];
        TTImageView *bookmarkView = [[TTImageView alloc] init];
        bookmarkView.defaultImage = bookmark;
        bookmarkView.frame = CGRectMake(297, 0, 16, 27);
        [self.contentView addSubview:bookmarkView];
        TT_RELEASE_SAFELY(bookmarkView);
}

基本上，如果我得到一个已添加书签的项目，我想在单元格的右侧显示一个功能区。此功能区可以正确显示。
当我使用操作表方法重新排序单元格并调用 invalidateModel 时，第一个没有任何功能区的单元格被放置在以前是功能区项目的位置，但没有重新绘制单元格，从而为没有功能区的项目提供功能区。

代码来源：
这是我的 TTTableViewController 的 createDatasource 函数：

- (void)createModel {
    self.dataSource = [ServiceRequestDetailedDataSource viewDataSource:self.typeOfAction andOrderBy:orderBy];
    // If dataSource nil, show an empty Message
    if (self.dataSource == nil) {
        [self showEmpty:YES];
    }
}

这是我的 TTTableViewController 的操作表操作，它更改 orderBy 并调用无效模型：

-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
    if (buttonIndex == 0) {
        self.orderBy = @"portfolio";
    [self invalidateModel];
}

任何提示都很棒，我真的被困在这里了:'(

原文

i have an awkward problem where calling to [self invalidateModel]; does not redraw my custom cells.

I have a TTTableViewController with an action sheet that allows to order the display of a table when pressed. The data gets redrawn correctly but the cells are not redrawn. Instead there are reused.

To illustrate better :
In my - (void)layoutSubviews { of my CustomTableItemCell class i have this :

if (bookmarked) {
        UIImage *bookmark = [UIImage imageNamed: @"[email protected]"];
        TTImageView *bookmarkView = [[TTImageView alloc] init];
        bookmarkView.defaultImage = bookmark;
        bookmarkView.frame = CGRectMake(297, 0, 16, 27);
        [self.contentView addSubview:bookmarkView];
        TT_RELEASE_SAFELY(bookmarkView);
}

Basically if I get a bookmarked item, I want to display a ribbon on the right of my cell. This ribbon gets display correctly.
When I reorder my cell with the action sheet method and call invalidateModel, the first cell which didn't have any ribon gets putten at a place where was previously a ribbonned item but without redrawing the cell, thus giving a ribon to an item without ribbon.

Code source :
This is my createDatasource function of my TTTableViewController :

- (void)createModel {
    self.dataSource = [ServiceRequestDetailedDataSource viewDataSource:self.typeOfAction andOrderBy:orderBy];
    // If dataSource nil, show an empty Message
    if (self.dataSource == nil) {
        [self showEmpty:YES];
    }
}

This is my action sheet action of my TTTableViewController that change the orderBy and calls invalidate model :

-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
    if (buttonIndex == 0) {
        self.orderBy = @"portfolio";
    [self invalidateModel];
}

Any tips would be great, I am really stuck here :'(
