Question

cell = [[[NSBundle mainBundle] loadNibNamed:@"Empty" owner:self options:nil] objectAtIndex:0];
    cell = [[[NSBundle mainBundle] loadNibNamed:@"Cell1" owner:self options:nil] objectAtIndex:1];

我得到超出边界错误的索引。我试图改变数字，但没有运气！任何帮助将不胜感激。我一直在谷歌搜索，在网上找到的所有解决方案都没有帮助。感谢。

要加载我正在使用的自定义笔尖，

制作NSObject类别类并在其中添加此代码。

+ (id)loadNibNamed:(NSString *)NibName {
    NSObject *cl = nil;
    if (NSClassFromString(NibName) != nil) {
        NSArray *arr = [[NSBundle mainBundle] loadNibNamed:NibName owner:self options:nil];
        for (id cls in arr) {
            if([cls isKindOfClass:NSClassFromString(NibName)])
            {
                cl = cls;
                break;
            }
        }
    }
    return cl;
}

并称之为，

 UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];
    if (cell == nil) {
        cell = (UITableViewCell *)[[class class] loadNibNamed:NSStringFromClass(class)];
    }

它会帮助你。
