Courses Plus Student 307 PointsPLEASE Help! Search Feature For Ribbit
I almost got the search for friends feature in Ribbit working. I did some of the coding from this post:
https://teamtreehouse.com/forum/adding-search-friends-to-ribbit
- I changed this code in EditFriendsViewController.m:
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (error) {
NSLog(@"Error: %@ %@", error, [error userInfo]);
}
else {
self.allUsers = nil; <<MADE THIS NIL
[self.tableView reloadData];
- I added this to the .m as well. I added @property (nonatomic, strong) PFUser *user; to the .h
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if (self.user) {
//a user was found, we need to display one row.
return 1;
}
else {
//a user was not found/searched for yet, dont display any rows
return 0;
}
// Return the number of rows in the section.
return [self.allUsers count];
}
Everything is added and there are no issues in Xcode but the search isn't showing someone when I type in their name and hit search...any suggestions?

42,016 Pointswhen the query finds a user, you need to set your user property as the user that was returned by the query
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (error) {
NSLog(@"Error: %@ %@", error, [error userInfo]);
}
else {
//set your user property to the first (and only) object in the objects array
self.user = [objects objectAtIndex:0];
[self.tableView reloadData];
}
you also need to update your cellForRowAtIndexPath to use your new user property as its data. so inside cellForRowAtIndexPath you need to make sure you set the text label using the user username.
cell.textLabel.text = self.user.username;

7,286 Pointshave you changed the data source for your tableview to self.user for numberOfRowsInSection and cellForRowAtIndexPath ?

Courses Plus Student 307 PointsThank you! I've been able to add everything!
In the simulator it when I press search it won't show any users, it that only because its not a actual device?

Courses Plus Student 307 PointsSo I guess I never connected the search bar property to the search bar and the search bar started working. But when I search for a person nothing comes up?
