Question

desc = [[NSMutableArray alloc] init];
for (NSString * strName in results) 
{
    arrRates = [results objectForKey:strName];
    for (int i = 0; i <= [arrRates count]; i++) 
    {
        if ([[[arrRates objectAtIndex:i] valueForKey:@"type"] isEqualToString:@"0"])
        {
            nextUrl = [[arrRates objectAtIndex:i] valueForKey:@"Nexturl"];
            [desc addObject:[[arrRates objectAtIndex:i] valueForKey:@"desc"]];
        }
    }
}
NSLog(@"type 0 desc is:--> %@",desc);

输出： -

我在json解析字段“desc”中有这种类型的数据。

此数据有一些“|” ＆安培; “;”分开的值。

从这种数据我希望将数据存储在两个不同的参数中，如...

title              id
-------            ----

Home               2028

Services           2029

Clients            2030

Portfolio          2031

Company            2032

Contact Us         2033

Career             2034

Answer 1

  NSString *desc=@"Home|2028;Services|2029;Clients|2030;Portfolio|2031";
NSArray *arr=[desc componentsSeparatedByString:@";"];
NSString *sub=@"|";
NSMutableArray *arrTitle=[[NSMutableArray alloc]init];
NSMutableArray *arrId=[[NSMutableArray alloc]init];
for (int i=0; i<[arr count]; i++) {
    [arrTitle addObject:[[arr objectAtIndex:i] substringToIndex:NSMaxRange([[arr objectAtIndex:i] rangeOfString:sub])-1]];
    [arrId addObject:[[arr objectAtIndex:i] substringFromIndex:NSMaxRange([[arr objectAtIndex:i] rangeOfString:sub])]];
}

使用JSON时，最好使用词典。

JSON基本上只是一个键值对列表。因此，您应该使用NSDictionary来存储值。

如果你有一个有效的JSON，那么有很多JSON解析器会派上用场。例如。 have a look
