我在第二個tableview時總是出錯。我使用storyboard創建一個簡單的應用程序。我的應用第一次運行時,它會顯示我創建的數據列表。如果用戶點擊該行,我想更改爲其他頁面,在其他頁面上也有一個tableview。我也對數據列表進行了硬編碼,但是我沒有顯示出來。從UITableView中選擇單元格並轉到另一個UITableView
我總是得到一個錯誤在這一部分
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"SubSiteCellDetail"];
cell.textLabel.text = [ListDetailSubSite objectAtIndex:indexPath.row]; //this always give me the error
return cell;
}
這裏是我創建的數據列表
ListDetailSubSite = [NSMutableArray arrayWithCapacity:10];
SubSite *detailSubSite = [[SubSite alloc] init];
detailSubSite.sSubSiteName = [subsite.sSubSiteName stringByAppendingString:@"1"];
[ListDetailSubSite addObject:detailSubSite];
detailSubSite = [[SubSite alloc] init];
detailSubSite.sSubSiteName = [subsite.sSubSiteName stringByAppendingString:@"2"];
[ListDetailSubSite addObject:detailSubSite];
這裏是如何,我從UITableView中移動到另一個UITableView的。
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([[segue identifier] isEqualToString:@"ShowSubSiteDetail"]) {
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
SubSite *subsetSelected = [ListSubSite objectAtIndex:indexPath.row];
[[segue destinationViewController] setSubsite:subsetSelected];
}
}
這是我的錯誤看起來像

這裏是圖:
類SubSite.h
#import <UIKit/UIKit.h>
@interface SubSite : NSObject
@property (nonatomic, copy) NSString *sSubSiteName;
@end
類SubSite.m
#import "SubSite.h"
@implementation SubSite
@synthesize sSubSiteName;
@end
任何人都可以幫我解決這個問題嗎?謝謝。
