自定义表视图控制器崩溃并显示"initWithCoder: unrecognized selector sent to instance"

Question

基于此处提供的示例代码（显示时间表），我创建了一个自定义twtrsearchviewController：

.h：

#import <TwitterKit/TwitterKit.h>
@interface TWTRSearchViewController : TWTRTimelineViewController
@end

.m：

#import "TWTRSearchViewController.h"
@interface TWTRSearchViewController ()
@end
@implementation TWTRSearchViewController
- (instancetype)init {
    TWTRAPIClient *APIClient = [[Twitter sharedInstance] APIClient];
    TWTRSearchTimelineDataSource *searchTimelineDataSource = [[TWTRSearchTimelineDataSource alloc] initWithSearchQuery:@"#twitterflock" APIClient:APIClient];
    return [super initWithDataSource:searchTimelineDataSource];
}
- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
}

这是TwtrtimelineviewController.h的标题：

//
//  TWTRTimelineViewController.h
//  TwitterKit

//  Copyright (c) 2015 Twitter. All rights reserved.
//
#import <UIKit/UIKit.h>
#import "TWTRTimelineDataSource.h"
/**
 This class is a `UITableViewController` subclass that displays `TWTRTweetTableViewCell` cells. It handles cell-reuse, cell-configuration, and loading more tweets from the given timeline once the last cell is reached.
 ## Usage
 Initialize this class with any object that conforms to the `TWTRTimelineDataSource` protocol. We provide two such classes, `TWTRUserTimelineDataSource` and `TWTRSearchTimelineDataSource`. These provide `TWTRTweet` objects to this table view which then configures the instances of `TWTRTweetTableViewCell`.
    // Create the data source
    TWTRAPIClient *client = [Twitter sharedInstance].APIClient;
    TWTRUserTimelineDataSource *dataSource = [[TWTRUserTimelineDataSource alloc] initWithScreenName:@"jack" APIClient:client];
    // Create the timeline view controller
    TWTRTimelineViewController *timeline = [[TWTRTimelineViewController alloc] initWithDataSource:dataSource];
 ## Loading More
 This class loads the first batch of `TWTRTweet` objects from the Twitter API when `viewWillAppear:` is received. It also handles loading more tweets automatically once the last cell has been shown.
 */
@interface TWTRTimelineViewController : UITableViewController
/**
   Initializes a timeline view controller. Does not start loading tweets until 
   `viewWillAppear:` is called. 
   This method must be used to initialize this class. The `init` method is unavailable.
   @param dataSource   Required. A timeline data source object that conforms to the `TWTRTimelineDataSource` protocol.
   @return A fully initialized `TWTRTimelineViewController` or nil if the data source is missing.
 */
- (instancetype)initWithDataSource:(id<TWTRTimelineDataSource>)dataSource __attribute((nonnull)) NS_DESIGNATED_INITIALIZER;
/**
  The source of `TWTRTweet` objects for this `TWTRTimelineViewController`.
  May be set to update the tweets being shown by this table view. Must be set on the main thread.
 */
@property (nonatomic, strong) id<TWTRTimelineDataSource> dataSource;
- (instancetype)initWithStyle:(UITableViewStyle)style __attribute__((unavailable("Use -initWithDataSource: instead")));
- (id)initWithCoder:(NSCoder *)aDecoder __attribute__((unavailable("Use -initWithDataSource: instead")));
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil __attribute__((unavailable("Use -initWithDataSource: instead")));
@end

应用程序启动后，它立即崩溃了错误消息：-[TWTRSearchViewController initWithCoder:]: unrecognized selector sent to instance 0x7a88f1d0。该应用程序甚至在调用init或viewDidLoad之前崩溃。

我的代码怎么了？对我可能错过的东西有任何想法吗？

谢谢

Answer 1

覆盖子类中的initWithCoder:方法，并在当前的init

Answer 2

我有同样的错误，也没有逻辑上的解释。即使刷出派生的数据，也无效。我最终所做的是，在名称中创建一个带有" 2"的新类，以将其与第一个区分开，将代码与崩溃的ViewController复制，然后使用。
