I’m new to this and in my application I use UISearchBar. When I enter any word to search in it the application crashes.

In my project I am using sqlite and values are fetched from the db in AppDelegate and saved in an NSMutableArray named docArray.

RootViewController.m

    - (void)viewDidLoad{
        listOfItems = [[NSMutableArray alloc] init];
        NSDictionary *value = [NSDictionary dictionaryWithObject:appDelegate.docArray forKey:@"doctors"];
        [listOfItems addObject:value];
        //  Intialize copy array that will store the result of search result
        copyListOfItems = [[NSMutableArray alloc] init];
            //  Add Search bar to main view .....
        self.tableView.tableHeaderView = searchBar;
        searchBar.autocorrectionType = UITextAutocorrectionTypeNo;

for one thing, please condense your code so we don’t have to scroll through all the newlines. Furthermore, is this the dataSource of your table view, and if so, where are:

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

they have to access copyListOfItems, which may fail and be the source of your crash.

What does the console show when it crashes?

edit: thanks for providing the extra info. Your problem lies here:

for (NSString *sTemp in searchArray)

searchArray contains “waitsup” objects, I think, not NSString. You cast it to an NSString pointer, but it’s your responsibility that it actually points to an NSString object. Therefore you get the error that rangeOfString is called on a waitsup, which is “unrecognized”. You cannot then call rangeOfString on the waitsup object, if you didn’t provide the rangeOfString method in it yourself.

Looking at the rest of your code, I think you could fix it like this:

for (waitsup *sTemp in searchArray) {
    NSRange titleResultsRange = [sTemp.name_last rangeOfString:searchText options:NSCaseInsensitiveSearch];
    if (titleResultsRange.length > 0)
        [copyListOfItems addObject:sTemp];
}

but then only name_last is searched. Expanding this to include more fields is trivial.
