ios - 无法显示跨到另一个 tableview 的 Tableview 和自定义表格单元格

Question

从一个 TableView 到另一个 TableView (使用 Xcode 4.2 和 iOS 5)。

第一页.h

#import "FavoritesController.h"

#import "Profiles.h"

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    FavoritesController * favoriteview = [[FavoritesController alloc] init];
    [favoriteview setTitle:@"Favorites"];

    NSMutableArray * profiles = [[NSMutableArray alloc]init ];
    profiles = [NSMutableArray arrayWithCapacity:20];

    Profiles * profile = [[Profiles alloc]init];
    profile.profile_name = @"Woot";
    profile.biz_type_desc = @"Woot 1";
    profile.profile_address = @"123, woot";
    profile.profile_email = @"woot@woot.com";
    [profiles addObject:profile];
    profile=[[Profiles alloc]init];
    profile.profile_name = @"Jin-Aurora";
    profile.biz_type_desc = @"Software";
    profile.profile_address = @"682A";
    profile.profile_email = @"jin@jin.biz";
    [profiles addObject:profile];

    [self.navigationController pushViewController:favoriteview animated:YES];
    favoriteview.profilelist = profiles; 
}

收藏夹 Controller .h

@interface FavoritesController : UITableViewController

@property(nonatomic,strong)NSMutableArray * profilelist;

@end

收藏 Controller .m

 #import "FavoritesController.h"
 #import "Profiles.h"
 #import "ProfileCell.h"

-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return 1;
}

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
   return [self.profilelist count];
}

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"ProfileCell";

    ProfileCell *cell = (ProfileCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    Profiles * profile = [self.profilelist objectAtIndex:indexPath.row];

    cell.nameLabel.text = profile.profile_name;
    cell.biztypeLabel.text = profile.biz_type_desc;

    // Configure the cell...

    return cell;
}

这是我得到的错误

Answer 1

您的 cellForRowAtIndexPath 方法尝试将可重复使用的单元格出列，但如果找不到则不会创建它(如果没有可重复使用的单元格，则会发生这种情况)

ProfileCell *cell = (ProfileCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (!cell)
    cell = [[[ProfileCell alloc] initWithStyle:style reusueIdentifier:CellIdenfitier] autorelease];
