Invalid argument type to unary expression - HELP!

[teCma]

Hey forum, noob here.

I have this program with a tableView as my first view. I have also implemented (or at least tried to) a search bar on top of the view. Have used several hours to search for a solution, but without positive results.

 #import "FirstViewController.h"
    #import "NSDictionary-MutableDeepCopy.h"


    @implementation FirstViewController

    @synthesize listData, table, search, allNames;

    #pragma mark -
    #pragma mark Custom Methods 
    -(void)resetSearch {
        NSMutableDictionary *allNamesCopy = [self.allNames mutableDeepCopy];
        self.names = allNamesCopy;
        [allNamesCopy release];
        NSMutableArray *keyArray = [[NSMutableArray alloc] init];
        [keyArray addObjectsFromArray:[[self.allNames allKeys]
                                       sortedArrayUsingSelector:@selector(compare:)]];
        self.keys = keyArray;
        [keyArray release];
    }

    -(void)handleSearchForTerm:(NSString *)searchTerm {
        NSMutableArray *sectionsToRemove = [[NSMutableArray alloc] init];
        [self resetSearch];

        for (NSString *key in self.keys) {
            NSMutableArray *array = [names valueForKey:key];
            NSMutableArray *toRemove = [[NSMutableArray alloc] init];
            for (NSString *name in array) {
                if ([name rangeOfString:searchTerm
                    options:NSCaseInsensitiveSearch].location == NSNotFound)
                    [toRemove addObject:name];
            }

            if ([array count] == [toRemove count])
                [sectionsToRemove addObject:key];

            [array removeObjectsInArray:toRemove];

            [toRemove release];

        }

        [self.keys removeObjectsInArray:sectionsToRemove];
        [sectionsToRemove release];
        [table reloadData];

    }

@end

My errors occur in the following:

#pragma mark -
#pragma mark Table View Delegate Methods
- (NSIndexPath *)tableViewUITableView *)tableView
willSelectRowAtIndexPathNSIndexPath *)indexPath {
[search resignFirstResponder];
return indexPath;

It's the third line. Im aware that it is the missing } just before this method. But when I insert that, the rest of the document becomes error'ed..

1. Invalid argument type 'NSIndexPath *' to unary expression
2. Wrong type argument to unary minus
3. Expected ';' before ':' token

I don't know if I should post more of my code, if needed - let me know. There's alot.

Thanks alot in advance...

Btw. sorry for bad english and grammar

[smasher]

As you said, you are missing the } at the end of your sectionIndexTitlesForTableView: method. You must fix that error.

After that you're missing a colon in this line:

-(void)searchBar(UISearchBar *)searchBar

should be

-(void)searchBar: (UISearchBar *)searchBar

In that same method you have self [resetSearch]; which is incorrect too.

Ehm. Thanks alot for your help - I do appreciate it.

I can launch my app, type in charaters, press cancel button - BUT: when i launch the app it highlights these line:

NSString *key = [keys objectAtIndex:section];
NSArray *nameSection = [names objectForKey:key];

it comes with an error that says Thread 1: Program recieved signal :"SIGABRT"... this it at the "self.names = allNamesCopy" line. O.o

If anybody has any suggestions for what i should do to make my array: listData searchable PLZZ LET ME KNOW. Also how to fix that error message which is actully green :O

Sorry that I'm so stupid xD - I guess I am.

I think the error is pretty clear

[NSMutableArray objectAtIndex:]: index 0 beyond bounds for empty array'

[teCma]

right, ty

but actully I dont really get my code :O

What is supposed to be stored in keys?...

[Domele]

The answer to that is to stop copying and pasting code you don't understand.

yes, I know that is very, very dumb. I just really want to get that searchbar function implemented in my program... I'm really reading and learning alot atm.

Even though I wrote it all my self, didnt paste - not that it matter's :/

[Domele]

Okay then. Pretty sure your keys arrays is supposed to be your datasource for your tableview.

Then I guess it's pretty fail that my array with all the data that is for the tableView is in an array called listData. O.o
