tableview-DidSelectRowAtIndexPath調用失敗

DidSelectRowAtIndexPath調用失敗

在masterTableView用到三個不同的detailTableViews ，觸屏時會調用，但是沒有調用成。

master.m文件：

#import "GuideTableViewController.h"
#import "GuideDetailTableViewController.h"
#import "GuideDetailTableViewController2.h"
#import "GuideDetailTableViewController3.h"
#import <QuartzCore/QuartzCore.h>

@interface GuideTableViewController (){

     NSMutableData *weatherResponseData;

    NSArray *headGuide;

    NSArray *leftImages;

}

@property (weak, nonatomic) IBOutlet UITableView *tableView;


@property (weak, nonatomic) IBOutlet UIImageView *imgHeader;


@property (weak, nonatomic) IBOutlet UIImageView *ImgTitle;


@property (weak, nonatomic) IBOutlet UIImageView *ImgWeather;


@property (weak, nonatomic) IBOutlet UIButton *btnMap;

@property (weak, nonatomic) IBOutlet UILabel *LabelWeather;

@property (weak, nonatomic) IBOutlet UILabel *LabelWeather2;

@end

最佳回答：

你的方法聲明大寫不對

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

應該是：

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

方法的名字是區分大小寫的。

另外，關於delegates：

self.tableView.delegate = self;
