didSelectRowAtIndexPath with section

Question

我有一个UITableView,我已经分配了部分.当使用带有indexPath.row的didSelectRowAtIndex时,我没有得到正确的值.假设我在第2部分,然后它再次将行索引设置为0,因此我得到了错误的索引.

谁能告诉我如何解决这个问题？我意识到可以通过indexPath.section获取段索引,但我无法弄清楚如何使用它.

bandDetailViewController.band = [self.programArray objectAtIndex:indexPath.row];

我希望你能帮助我.提前致谢 :-)

样本数据.表视图的我的单元格是从此plist加载的.

Answer 1

我刚刚遇到过这个问题.我找到了一个简单的解决方案,使用你提到的节号.下面的代码使用segues从两个不同的行导航到新的controlView.非常简单的解决方案!

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {


if (indexPath.section == 0)
{


    switch(indexPath.row) {
        case 0:
            [self performSegueWithIdentifier:@"Mission" sender:self];
            break;
        case 1:
            //[self performSegueWithIdentifier:@"Music" sender:self];
            break;

     }
}else{

    switch(indexPath.row) {
        case 0:
            [self performSegueWithIdentifier:@"Contact" sender:self];
            break;
        case 1:
            //[self performSegueWithIdentifier:@"Home" sender:self];
            break;
    }


}

}

Answer 2

的rows不连续,在每个从头开始section:

第0部分:
第0
行第1
行第2
行......

第1节:
第0
行第1
行第2
行......

...

最好的方法是使用NSMutableArrays为行构建NSMutableArray节.比你的代码变得非常容易:

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    return cellSections.count;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    CellSection *cellSection = [cellSections objectAtIndex:section];
    return cellSection.cellElements.count;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    NSString *cellIdentifier = [NSString stringWithFormat:@"Cell-%i-%i", indexPath.section, indexPath.row];

    CellSection *cellSection = [cellSections objectAtIndex:indexPath.section];
    CellElement *cellElement = [cellSection.cellElements objectAtIndex:indexPath.row];

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier] autorelease];

        [cell.contentView addSubview:cellElement.contentView];

    }


    return cell;

}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    CellSection *cellSection = [cellSections objectAtIndex:indexPath.section];
    CellElement *cellElement = [cellSection.cellElements objectAtIndex:indexPath.row];

}

举个例子:

@interface CellSection : NSObject {

}

@property (nonatomic, retain) NSMutableArray *cellElements;
@property (nonatomic, retain) NSString *headerString;
@property (nonatomic, retain) UIView *headerView;

@end

@interface CellElement : NSObject {

}

@property (nonatomic, retain) UIView *contentView;
@property BOOL isSelectable;
@property BOOL hasAccessoryIndicator;
@property SEL action;

@end
