(iOS) How to add space on google autocomplete for search bar

I am fairly new to iOS. I am trying to use google autocomplete and have it
working...mostly. :)
I have a UISearchBar and when a user enters a string in search bar it
autocompletes with predicted places (businesses). However when I click on
a space the code suddenly goes to following method:-
(void)connection:(NSURLConnection *)connection didFailWithError:(NSError
*)error
I need a way to search a string with spaces. For example is a user types
in 'london' it is fine. As soon as the put 'london england' the program
will go to the error method and fail. Also you technically wouldn't be
able to write 'england' the error happens as soon as there is a space
after london.
This is the page, that provides information but I can't see what I am
after:
https://developers.google.com/places/documentation/autocomplete#location_biasing
Below are the methods that I think are most relevant.
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
self.autoCompleteResults = [NSJSONSerialization
JSONObjectWithData:self.autoCompleteNSData options:nil error:nil];
//test logging
NSLog(@"Connection did finish loading");
NSLog(@"Auto Complete Results - Dictionary: %@ ",
self.autoCompleteResults);
//parse the auto complete results
self.filteredStrings = [self.autoCompleteResults
objectForKey:@"predictions" ];
NSLog(@"Auto Complete Results - Array: %@", self.filteredStrings);
int i = [self.filteredStrings count];
NSLog(@"Count of array: %i", i);
int n = 0;
for (n = 0; n < i;n= n+1) {
NSString *tempDescription = [[self.filteredStrings
objectAtIndex:n]objectForKey:@"description"];
NSLog(@"tempDescription: %@", tempDescription);
}
}
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError
*)error
{
NSLog(@"Connection didfail with error");
UIAlertView *connectionErrorView = [[UIAlertView
alloc]initWithTitle:@"Connection error" message:@"There is a problem
with the connection. Please ensure that you are connected to 3G or
Wi-Fi" delegate:nil cancelButtonTitle:@"Dismiss"
otherButtonTitles:nil];
[connectionErrorView show];
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
}
//self.filteredStrings is a NSMutableArray (not dictionary)
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView
dequeueReusableCellWithIdentifier:CellIdentifier];
if (!cell) {
cell = [[UITableViewCell
alloc]initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier];
}
if (self.filteredStrings) {
cell.textLabel.text = [[self.filteredStrings
objectAtIndex:indexPath.row]objectForKey:@"description"];
}else{
cell.textLabel.text = @"Currently no results";
}
return cell;
}
-(void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString
*)searchText
{
//To check if alphanumerical characters have been entered
NSString *alphaStr = @"aA09";
NSCharacterSet *alphaSet = [NSCharacterSet alphanumericCharacterSet];
BOOL valid = [[alphaStr stringByTrimmingCharactersInSet:alphaSet]
isEqualToString:searchText];
NSLog(@"SearchText String: %@", searchText);
//The if is needed because without it the program crashes when you
clear the field via the 'X' button in search bar
if (valid) {
NSLog(@"SearchText passed !SearchText: %@", searchText);
}else{
NSLog(@"SearchText should be full: %@", searchText);
NSString *autoCompleteUrl = [NSString
stringWithFormat:@"https://maps.googleapis.com/maps/api/place/autocomplete/json?input=%@&types=establishment&location=37.76999,-122.44696&radius=500&sensor=true&key=Mykey",
searchText];
NSURL *url = [NSURL URLWithString:autoCompleteUrl];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[[NSURLConnection alloc]initWithRequest:request delegate:self];
[self.autoCompleteTableView reloadData];
}
}
