Question

以下是从Google地方信息自动填充API获取NSDictionary的代码：

(GooglePlacesAutocompletePlace *)placeFromDictionary:(NSDictionary *)placeDictionary 
{
    GooglePlacesAutocompletePlace *place = [[self alloc] init];
    place.name = [placeDictionary objectForKey:@"description"];
    return place;
}

上面的代码将以下内容存储在place.name中：

"Name: Apple Store Palo Alto, University Avenue, Palo Alto, CA, United States"

结果以逗号分隔。在将其存储在place.name之前删除Country的名称的最佳方法是什么。我想只显示州的地址。

Answer 1

你可以使用rangeOfString：options：range和NSBackwardsSearch选项找到最后一个逗号：

    NSString *s = @"Name: Apple Store Palo Alto, University Avenue, Palo Alto, CA, United States";
    NSRange lastCommaRange = [s rangeOfString:@"," options:NSBackwardsSearch range:NSMakeRange(0, s.length)];
    NSString *noCountryString = [s substringToIndex:lastCommaRange.location];
    NSLog(@"%@",noCountryString);
