根据这里提供的示例代码(Show Timelines),我创建了一个自定义的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

#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,它会立即崩溃,并显示错误消息:-[TWTRSearchViewController initWithCoder:]: unrecognized selector sent to instance 0x7a88f1d0
。应用程序甚至在调用init
或viewDidLoad
之前就崩溃了。
我的代码出了什么问题?关于我可能错过的任何想法?
谢谢
覆盖子类中的initWithCoder:
方法,并执行与当前init
相同的操作
我有类似的错误,也没有合理的解释。即使刷取衍生数据等也不起作用。我最后做的是,在名称中创建一个名为“2”的新类,以区别于第一个,从崩溃的viewcontroller复制代码然后它工作。
