我使用UITableViewControllerdetailView来显示一个实体细节.我在我的viewDidLoad方法中填充了PFQuery的一行数据.我有一个单元格,我正在使用标签,我想根据大小更改NSString大小.我检查了很多答案,但都与indexPath动态相关,我有静态单元格.My label显示完整的字符串,但我的单元格已修复.如何更改单元格的高度？请帮我纠正这个问题.

这是我的代码:

- (void)viewDidLoad
{
    [super viewDidLoad];
    PFQuery *query = [PFQuery queryWithClassName:@"Entities"];
    [query whereKey:@"name" equalTo:entityName];
    [query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
        if (!error) {
            PFFile *thumbnail = [objects[0]  objectForKey:@"image"];
            detailsImageView.image = [UIImage imageNamed:@"loader.gif"];
            detailsImageView.file = thumbnail;
            [detailsImageView loadInBackground];
            detailLabel.numberOfLines = 0; // this label need dynamic height and its cell
            detailLabel.text = [objects[0]  objectForKey:@"descriptionLarge"];
            [detailLabel sizeToFit];
        } else {
            NSString *errorString = [[error userInfo] objectForKey:@"error"];
            NSLog(@"Error: %@", errorString);
        } …
