Question

我正在尝试使用Codeigniter分页，我收到以下错误＆＃34;致命错误：调用未定义的方法Pagination :: initialize（）＆＃34;。

我发现了一些有相同问题的帖子，但他们都表示解决方案是自动加载我已经在做的Pagination类。我能想到的唯一问题是我的班级使用自定义控制器＆＃34; MY_Controller＆＃34;它扩展了CI控制器。以下是我的代码，请帮忙。提前谢谢。

MY_Controller.php

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class MY_Controller extends CI_Controller {

public function __construct()
{
    parent::__construct();

    $this->init();
}

}

主控制器

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Main extends MY_Controller {

function index()
{
    $this->display();   
}

function display()
{
//pagination settings
$config['base_url']    = base_url();
$config['total_rows']  = 200;
$config['per_page']    = 50;

$this->pagination->initialize($config);
}
}

如果你创建了一个自定义控制器并使用核心@interface DownloadManager () @property (nonatomic, strong) NSProgress *progress; @property (nonatomic, strong) Settings *settings; @property (nonatomic, strong) DocumentDirectory *documentDirectory; @end @implementation DownloadManager - (instancetype)init { self = [super init]; if (self) { self.progress = [NSProgress new]; [self.progress addObserver:self forKeyPath:@"fractionCompleted" options:NSKeyValueObservingOptionNew context:NULL]; self.settings = [Settings new]; self.documentDirectory = [DocumentDirectory new]; } return self; } - (void) dealloc { [self.progress removeObserver:self forKeyPath:@"fractionCompleted"]; } //Download the file from remote server in the document directory as Zip format - (void) downloadCarContents:(NSArray *)urlArray forContent:(NSArray *)contentArray { AFHTTPSessionManager *manager = [AFHTTPSessionManager manager]; self.progress.totalUnitCount = urlArray.count; self.progress.completedUnitCount = 0; for (NSInteger i = 0; i < urlArray.count; i++) { NSString *destinationPath = [self.documentDirectory getDownloadContentPath:contentArray[i]]; NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:urlArray[i]]]; NSURLSessionTask *task = [manager downloadTaskWithRequest:request progress:nil destination:^NSURL *(NSURL *targetPath, NSURLResponse *response) { return [NSURL fileURLWithPath:destinationPath]; } completionHandler:^(NSURLResponse *response, NSURL *filePath, NSError *error) { }]; NSProgress *childProgress = [manager downloadProgressForTask:task]; [self.progress addChild:childProgress withPendingUnitCount:1]; NSLog(@"Total downloaded : %f", self.progress.fractionCompleted * 100.0); [task resume]; } } @end扩展它而不是My_Controller函数中的加载分页库：

display()
