UIWebView將不會顯示UTF8String

Question

我試圖從SQLite數據庫中拉出文章並將它們顯示在表格視圖中。選擇表格單元格時，應該在源頁面中顯示Web視圖。到目前爲止，除了顯示源頁面之外，所有內容都可以工下面是我的一些代碼：

（在init方法）

articles = [[NSMutableArray alloc] init]; 
    webPages = [[NSMutableArray alloc] init]; 
    int arrayCount = data.count; 
    int i; 
    for (i = 0; i < arrayCount; i++) { 
     Item *currentItem = [[Item alloc] init]; 
     currentItem = [data objectAtIndex:i]; 
     [articles insertObject:currentItem.itemTitle atIndex:i]; 
     [webPages insertObject:currentItem.detailURL atIndex:i]; 
     NSLog(@"%@", [webPages objectAtIndex:i]); 
     //[webPages insertObject:@"http://onlyfans.cstv.com/schools/tul/sports/w-volley/recaps/102812aaa.html" atIndex:i]; -- >this works fine. i got this url from the nslog above. 

    } 

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { 
    WebViewController *webViewController = [[WebViewController alloc] initWithString:[webPages objectAtIndex: 
    indexPath.row]]; 
    [self.parentViewController.navigationController pushViewController:webViewController animated:YES]; 

這是用於獲取有關從數據庫中每一條信息的方法...

if(sqlite3_open([self.databasePath UTF8String], &database) == SQLITE_OK) { 

    NSLog(@"DataLoader::readItemsFromDatabase : database open successful!"); 

    sqlite3_stmt *compiledStatement; 

    if(sqlite3_prepare_v2(database, [sqlStatement UTF8String], -1, &compiledStatement, NULL) == SQLITE_OK) { 
     NSLog(@"select ok."); 
     // Loop through the results and add them to the feeds array 
     while(sqlite3_step(compiledStatement) == SQLITE_ROW) { 
      // Read the data from the result row 

      int lineItemsID=sqlite3_column_int(compiledStatement, 0); 

      NSLog(@"DataLoader::readItemsFromDatabase : source id [%i]", lineItemsID); 

      NSString *aItemTitle = @" "; 
      NSString *aPublishDate = @" "; 
      NSString *aDetailURL = @" "; 
      NSString *aDesc = @" "; 

      if (sqlite3_column_text(compiledStatement, 2) != nil) { 
       aItemTitle=[NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 2)]; 
       NSLog(@"DataLoader::readItemsFromDatabase :row>>id %i, itemTitle %s",lineItemsID,sqlite3_column_text(compiledStatement, 2)); 
       // NSLog(@"DataLoader::readSourcesFromDatabase :row>>id %i, name %s",lineItemsID,aItemTitleL); 
      } 

      if (sqlite3_column_text(compiledStatement, 3) != nil) { 
       aPublishDate=[NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 3)]; 
       NSLog(@"DataLoader::readItemsFromDatabase :row>>id %i, publishDate %s",lineItemsID,sqlite3_column_text(compiledStatement, 3)); 
      } 

      if (sqlite3_column_text(compiledStatement, 4) != nil) { 
       aDetailURL=[NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 4)]; 
       NSLog(@"DataLoader::readItemsFromDatabase :row>>id %i, detail URL %s",lineItemsID,sqlite3_column_text(compiledStatement, 4)); 

      } 

      if (sqlite3_column_text(compiledStatement, 5) != nil) { 
       aDesc=[NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 5)]; 
       NSLog(@"DataLoader::readItemsFromDatabase :row>>id %i, desc %s",lineItemsID,sqlite3_column_text(compiledStatement, 5)); 
      } 

      Item *item= [[Item alloc] init]; 
      item.itemTitle = aItemTitle; 
      item.publishDate = aPublishDate; 
      item.detailURL = aDetailURL; 
      item.desc = aDesc; 

我可以不明白爲什麼我可以從currentItem對象獲取URL字符串並將其顯示在NSLog中，但我無法直接使用它打開一個webview。有人有過這種問題嗎？

感謝您的幫助！

嘗試的NSLog：

[webPages objectAtIndex:indexPath.row]; 

在didSelectRowAtIndexPath方法

，看看它返回。

此外問題可能是您聲明您的網頁。嘗試使用：

@property(nonatomic, strong) NSMutableArray *webPages; 

合成：

webPages = _webPages; 

，並嘗試初始化您在viewDidLoad中的網頁：

self.webPages = [[NSMutableArray alloc] init];
