Question

任何人都可以帮助我。如何使用WEB API或带有JSON＆amp ;;的SERVER API来获取远程数据？然后在iphone中存储到SQLite表中如何做到这一点。对于获取数据我想使用JSON.In SQLite数据库表是user_detailes，其中包含用户名＆amp;密码。服务器也有我想要获取的相同数据。帮助我。

提供一些提示或链接或示例来解决此问题

Answer 1

NSString * txtUsername = @“”;

NSString * txtPassword = @"";

sqlite3 *database;

NSString *sqlStatement = @"";

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

    sqlStatement = [NSString stringWithString:@"select * from account_info "];
    NSLog(@"%@",sqlStatement);
    sqlite3_stmt *compiledStatement;

    if(sqlite3_prepare_v2(database, [sqlStatement cStringUsingEncoding:NSUTF8StringEncoding], -1, &compiledStatement, NULL) == SQLITE_OK) 
    {

        while(sqlite3_step(compiledStatement) == SQLITE_ROW) 
        {
            txtUsername = [[NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 1)] retain];
            txtPassword = [[NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 2)] retain];

        }
    }

    sqlite3_finalize(compiledStatement);
    sqlite3_close(database);

if（txtUsername isEqulaToString：@“user1”]） { //在这里使用UIAlertView }

在iphone中获取数据并进行编译
