objc表头是否隐藏表行

Question

我有一个tableView，在其中添加了一个标题部分。不知怎的，标题隐藏了行。。。当我删除标题部分时，行是可见的。当我添加标题部分时，它会隐藏行。通常情况下，排应在集管段之后可见。我没有胶水为什么这不起作用。。。

我有一个类似的tableView，在那里它可以完美地使用相同的设置，显示标题和行。

表格标题部分和行应同时可见。我该怎么做代码下方：

LocationViewController.h

#import <UIKit/UIKit.h>
#import "SingletonClass.h"
#import "WebApi.h"
#import <AFNetworking/UIImageView+AFNetworking.h>
@interface LocationViewController : UITableViewController
@property (nonatomic, strong) SingletonClass *sshare;
@property (nonatomic, strong) WebApi *swebapi;
@property (strong, nonatomic) IBOutlet UITableView *tableView;
@property (strong, nonatomic) NSString *locationID;
@end

LocationViewController.m

#import "LocationViewController.h"
@interface LocationViewController ()
@end
@implementation LocationViewController

{
    self = [super initWithStyle:style];
    if (self) {
    }
    return self;
}
- (void)vinit {
    self.sshare = [SingletonClass sharedInstance];
    self.swebapi = [[WebApi alloc] init];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handleNotification:) name:@"reloadDetails" object:nil ];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handleNotification:) name:NFlocationReload object:nil ];
}

{
    [self vinit]; 
    [self.navigationController setNavigationBarHidden:NO animated:NO];
    [super viewDidLoad];
    self.tableView.tableFooterView = [[UIView alloc] init]; 
    [self getData]; 
}
- (void)viewDidAppear:(BOOL)animated
{
    [self.navigationController setNavigationBarHidden:NO animated:NO];
}
-(void)handleNotification:(NSNotification *)message {
    if ([[message name] isEqualToString:@"reloadDetails"]) {
        [self.tableView reloadData];
    }
    if ([[message name] isEqualToString:NFlocationReload]) {
        DLog(@"%@, lData", self.sshare.lData);
        [self.tableView reloadData];
    }
}

    UIImageView *BGView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 10, 320, 174)];
    [BGView setBackgroundColor:[UIColor whiteColor]];
    UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 169)];
    [imageView setBackgroundColor:[UIColor orangeColor]];
    imageView.contentMode = UIViewContentModeScaleAspectFill;
    [imageView setClipsToBounds:YES];
    NSString *photoURL;
    if (self.sshare.imageDetails) {
        photoURL = self.sshare.imageDetails.url
        [imageView setImageWithURL:[NSURL URLWithString:photoURL] placeholderImage:[UIImage imageNamed:@"foo.jpg"]];
        [BGView addSubview:imageView];
    }
    return BGView;
}

Answer 1

它缺少一个委托方法。来自viewForHeaderInSection上的文档：。。。

返回的对象可以是UILabel或UIImageView对象，以及自定义视图。只有当tableView:heightForHeaderInSection:也实现了。

所以添加。。。

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {
    return 174;
}
