googlePlaces string problem iphone

1. i want to put name having spaces in googlePlaces query sting. my string is:

   googleUrl=[[NSString alloc] initWithFormat:@"https://maps.googleapis.com/maps/api/place/search/xml?location=%f,%f&radius=500&name=the burber shop&sensor=fal开发者_JAVA技巧se&key=mykey",ab,bb];

Please note

"&name=the burber shop" 

in above string. If i put &name=asda it works but because the burber shop has space in it, it does not work. Please suggest.

2 i want to get full address of all shops. how to do that.

You need to encode the URL.
