有没有办法让MKMapView放置一个给定地址的引脚？不使用坐标

is there a way to make the MKMapView place a pin with a given address? Without using the Coordinates

推荐答案

这里有一个片段我在应用程序中使用的代码

here is a snippet of code I used in an application

-(CLLocationCoordinate2D) getLocationFromAddressString:(NSString*) addressStr {
    NSString *urlStr = [NSString stringWithFormat:@"http://maps.google.com/maps/geo?q=%@&output=csv", 
                           [addressStr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
    NSString *locationStr = [NSString stringWithContentsOfURL:[NSURL URLWithString:urlStr]];
    NSArray *items = [locationStr componentsSeparatedByString:@","];

    double lat = 0.0;
    double lon = 0.0;

    if([items count] >= 4 && [[items objectAtIndex:0] isEqualToString:@"200"]) {
        lat = [[items objectAtIndex:2] doubleValue];
        lon = [[items objectAtIndex:3] doubleValue];
    }
    else {
        NSLog(@"Address, %@ not found: Error %@",addressStr, [items objectAtIndex:0]);
    }
    CLLocationCoordinate2D location;
    location.latitude = lat;
    location.longitude = lon;

    return location;
}
