小编ace*_*des的帖子

我在stackoverflow中看了几乎所有关于这个的相关问题,并尝试了所有可能的解决方案,但我仍然无法弄清楚为什么我会收到此错误:

*** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<CustomCell 0x6e627d0> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key title.'

我正在尝试使用nibname加载自定义表格视图单元格:@"CustomCell".它的类被分配给"CustomCell"(与nib名称相同的类名).它的文件所有者也设置为加载这些单元格的类 - "ProductsTableViewControllerWithSearch".笔尖中的所有插座都连接到CustomCell.m中的插座

这是我的代码:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellClassName = @"CustomCell";
    static NSString *CellIdentifier = @"Custom Items Cell";

    CustomCell *cell = (CustomCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil)
    {

      NSArray *topLevelItems =  [[UINib nibWithNibName:CellClassName bundle:[NSBundle mainBundle]] instantiateWithOwner:self options:nil];
        cell = [topLevelItems objectAtIndex:0];

    }
//... more irrelevant code here
}

请有人帮帮我.我已经工作了4个多小时.非常感谢!

PS:我正在使用ARC,正在为iOS …

我正在尝试将NSDictionary转换为XML.(我成功地将NSDictionary转换为JSON).但现在我需要将NSDictionary转换为XML.在Objective-C中是否有类似JSON的内置序列化程序？

int r = arc4random() % 999999999;

//simulate my NSDictionary (to be turned into xml)
NSString *name = [NSString stringWithFormat:@"Posted using iPhone_%d", r];
NSString *stock_no = [NSString stringWithFormat:@"2342_%d", r];
NSString *retail_price = @"12345";

NSArray *keys = [NSArray arrayWithObjects:@"name", @"stock_no", @"retail_price", nil];
NSArray *objects = [NSArray arrayWithObjects:name,stock_no,retail_price, nil];
NSDictionary *theRequestDictionary = [NSDictionary dictionaryWithObjects:objects forKeys:keys];

NSDictionary *theFinalRequestDictionary = [NSDictionary dictionaryWithObject:theRequestDictionary forKey:@"product"];

... //省略了其他不相关的代码

NSData *theBodyData = [NSPropertyListSerialization dataFromPropertyList:theFinalRequestDictionary format:NSPropertyListXMLFormat_v1_0   errorDescription:nil];
NSPropertyListFormat format;

id XMLed = [NSPropertyListSerialization propertyListFromData:theBodyData
                                            mutabilityOption:NSPropertyListImmutable
                                                      format:&format
                                            errorDescription:nil];

NSLog(@"the XMLed …

我想设计一个看起来几乎与此类似的网站:http: //bird-nest.com.my/v1/

我想要一个类似的照片幻灯片放映与缩略图和细节弹出和东西.

有人知道CMS用于这个网站吗？Wordpress也许吧？
