I think you have to escape the url string. Try using somthing like this.

+(NSString *)escapeURL:(NSString *)text{
CFStringRef tmp=CFURLCreateStringByAddingPercentEscapes(
                                                        NULL,
                                                        (CFStringRef)text,
                                                        NULL,
                                                        (CFStringRef)@"!*'\"();:@&=+$,/?%#[]% ",
                                                        kCFStringEncodingUTF8 );
NSString * encodedString = (NSString *)tmp;
return encodedString;

}
