Ios NSString中的UITableViewCell Nib

我正试图根据数组中存储的信息更改将使用的自定义单元格。我已经尝试了所有的方法，但似乎无法让它正常工作。代码似乎不接受单元格nib的字符串输入。还有别的办法吗？将在下面附上我的代码

谢谢

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

{
    if([[Tutortrackinbud[indexPath.row] valueForKey:@"reply"]  isEqual: @"N"])
    {
        nib = @"ReviewCell1";
    }
    else{
          nib = @"ReviewCell2";
    }
    static NSString *simpleTableIdentifier = nib;



    ReviewCell1TableViewCell *cell = (ReviewCell1TableViewCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];

    if (cell == nil)

    {

        NSArray *nibArray = [[NSBundle mainBundle] loadNibNamed:nib owner:self options:nil];

        cell = [nibArray objectAtIndex:0];

    }
    if ([[Tutortrackinbud[indexPath.row] valueForKey:@"stars"]  isEqual: @"1"]){
        NSLog(@"1");
        cell.star1.image = [UIImage imageNamed:@"star.png"];
        cell.star2.image = [UIImage imageNamed:@"greystar.png"];

您最好在

viewDidLoad

示例代码：

UINib *cellNib = [UINib nibWithNibName:@"MyCustomCell" bundle:nil];
[self.tableView registerNib:self.cellNib forCellReuseIdentifier:@"CustomCell"];

---

然后使用

dequeueReusableCellWithIdentifier

，就像您已经做的那样。您可以注册多个具有不同标识符的

nib

文件，只需在

cellforrowatinexpath

中将它们以其唯一标识符排在队列中即可。

您最好在

viewDidLoad

中注册nib文件

示例代码：

UINib *cellNib = [UINib nibWithNibName:@"MyCustomCell" bundle:nil];
[self.tableView registerNib:self.cellNib forCellReuseIdentifier:@"CustomCell"];

然后使用

dequeueReusableCellWithIdentifier

，就像您已经做的那样。您可以使用不同的标识符注册多个

nib

文件，只需在

cellForRowAtIndexPath

中使用其唯一标识符将它们排在队列中。

我建议，而不是多个

xib

文件您需要创建单个

xib

文件，然后从

NSArray

获取对象

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{

    static NSString *simpleTableIdentifier = nib;

    ReviewCell1TableViewCell *cell = (ReviewCell1TableViewCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];

    if (cell == nil){
        NSArray *nibArray = [[NSBundle mainBundle] loadNibNamed:nib owner:self options:nil];

         if([[Tutortrackinbud[indexPath.row] valueForKey:@"reply"]  isEqual: @"N"]){
               cell = [nibArray objectAtIndex:0];
         }else{
              cell = [nibArray objectAtIndex:1];
         }
    }


    return cell;
}

         }else{
              cell = [nibArray objectAtIndex:1];
         }
    }


    return cell;
}

在我的项目中，我经常使用如下类方法执行基本单元：

+ (NSString *)reuseIdentifier {
    return NSStringFromClass([self class]);
}

+ (UINib *)nibName {
    return [UINib nibWithNibName:NSStringFromClass([self class]) bundle:nil];
}

所有其他单元格都从中进行子类化，并在需要时以这种方式使用它：

 [self.tableView registerNib:[UINib nibWithNibName:[FeedCell nibName] bundle:nil] forCellReuseIdentifier:[FeedCell reuseIdentifier]];
