Question

我有一个分组表，如果我写：

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
        if (indexPath.row == 7){

它没有点击第7行...

我有这种UITableView（分组）：

- (void)viewDidLoad {
    NSArray *arrTemp1 = [[NSArray alloc]
                         initWithObjects:@"Scuola/Università",@"Uscita con le amiche",@"Pranzo di lavoro",@"Lavoro",@"Appuntamento",@"All'ultimo momento",nil];
    NSArray *arrTemp2 = [[NSArray alloc]
                         initWithObjects:@"Cena con amici",@"Cena di lavoro",@"Pub/Discoteca",@"Festa elegante",@"Appuntamento",@"All'ultimo momento",nil];
    NSArray *arrTemp3 = [[NSArray alloc]
                         initWithObjects:@"Compleanno",@"Anniversario",@"Matrimonio",@"Laurea/Promozione",@"San Valentino",@"Natale/Capodanno",nil];
    NSArray *arrTemp4 = [[NSArray alloc]
                         initWithObjects:@"Scelta e uso fondotinta",@"Scelta dei colori",@"I pennelli",@"Come sfumare",@"Contouring",@"Labbra perfette",nil];
    NSDictionary *temp =[[NSDictionary alloc]
                         initWithObjectsAndKeys:arrTemp1,@"Trucco da giorno",arrTemp2,
                         @"Trucco da sera",arrTemp3,@"Eventi speciali",arrTemp4,@"Lezioni di base",nil];
    self.tableContents =temp;
    [temp release];
    self.sortedKeys =[[self.tableContents allKeys]
                      sortedArrayUsingSelector:@selector(compare:)];
    [arrTemp1 release];
    [arrTemp2 release];
    [arrTemp3 release];
    [arrTemp4 release];
    [super viewDidLoad];
}

我是否需要与== 7不同的东西？

提前谢谢

整个代码：

#import "TabellaController.h"

@implementation TabellaController
@synthesize tableContents;
@synthesize sortedKeys;



- (UITableViewCellAccessoryType)tableView:(UITableView *)tableView accessoryTypeForRowWithIndexPath:(NSIndexPath *)indexPath {  
    return UITableViewCellAccessoryDisclosureIndicator;
}

// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
    NSArray *arrTemp1 = [[NSArray alloc]

    NSArray *arrTemp2 = [[NSArray alloc]

- (void)dealloc {

Answer 1

if (indexPath.row == 7)没有显示第七行显示第8行，所以你可能只有7行，而且选择类型也可能是none。所以检查一下。

编辑：

好的，您需要将if(indexPath.row == 7)行更改为

 if (indexPath.section == 1 && indexPath.row==0)

实际上这里发生了什么，你正在制作3节有6行，所以对于第七行，你可以访问第1节然后第0行用于访问第13行，你需要访问第2节和第0行。

现在我觉得你可以理解。

至于第一组只能点击，我相信这是由于你创建表格单元格的方式。尝试替换：


cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero
                                                     reuseIdentifier:@"cellID"]

with：


cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
                                                     reuseIdentifier:@"cellID"]

第二：当你在每个tempArray上定义了6行时，我不明白为什么你试图在第6行（第7行）上检测点击。确保永远不会检测到点击，因此永远不会创建“详细”视图控制器。
