插入html字符串到sqlite數據庫使用目標c

Question

我使用下面的代碼片段插入到sqlite數據庫的html字符串，我的代碼工作正常，但是當我檢索相同的html字符串並在web視圖中顯示它不呈現，一些數據正在修改，任何人都可以請幫助如何將長的html字符串插入數據庫。

爲const char * SQL = 「插入到文章 （art_id，sub_cat_id，art_title，art_details）VALUES（？，？，？？）」;

    if(sqlite3_prepare_v2(database, sql, -1, &addStmt, NULL) != SQLITE_OK) 
         NSAssert1(0, @"Error while creating add statement. '%s'", sqlite3_errmsg(database)); 

        sqlite3_bind_text(addStmt, 1, [[tuser objectForKey:@"art_id"] UTF8String], -1, SQLITE_TRANSIENT); 
        sqlite3_bind_text(addStmt, 2, [[tuser objectForKey:@"sub_cat_id"] UTF8String], -1, SQLITE_TRANSIENT); 
        sqlite3_bind_text(addStmt, 3, [[tuser objectForKey:@"art_title"] UTF8String], -1, SQLITE_TRANSIENT); 
        sqlite3_bind_text(addStmt, 4, [[tuser objectForKey:@"art_details"] UTF8String], -1, SQLITE_TRANSIENT); 


        if(SQLITE_DONE != sqlite3_step(addStmt)) 
         NSAssert1(0, @"Error while inserting data. '%s'", sqlite3_errmsg(database)); 
        else 
         //SQLite provides a method to get the last primary key inserted by using sqlite3_last_insert_rowid 
         //coffeeID = sqlite3_last_insert_rowid(database); 

         //Reset the add statement. 
         sqlite3_reset(addStmt);

單引號內是有可能導致該問題。由於它是HTML，因此您可以使用&替換單引號;或者你可以在「雙節」像這裏顯示的單引號，這樣SQLite是接受這個：

NSString *artdetails = [tuser objectForKey:@"art_details"]; 
    NSString *arttitle = [tuser objectForKey:@"art_title"]; 

    NSString *ad = [artdetails stringByReplacingOccurrencesOfString:@"'" withString:@"''"];  
    NSString *at = [arttitle stringByReplacingOccurrencesOfString:@"'" withString:@"''"]; 

...

sqlite3_bind_text(addStmt, 3, [at UTF8String], -1, SQLITE_TRANSIENT); 
    sqlite3_bind_text(addStmt, 4, [ad UTF8String], -1, SQLITE_TRANSIENT);
