I have some arrays whose contents are picked from db.I want to match up the text i have entered in 'searchTextField' with those array's contents which is taken from DB.
For example: my array contains, myArray={'bat man','bat and ball','ball'};
if i have entered 'bat' in 'searchTextField'; it must show index of matching text in array(in this case index 0 and 1).
How can i achieve this.. Waiting for your help..
NSMutableArray *tempArray = [NSMutableArray arrayWithObjects:@"bat man",@"bat and ball",@"ball", nil];
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF contains[c] 'bat'"];
NSArray *result = [tempArray filteredArrayUsingPredicate:predicate];
result array will be containing the filtered objects, from there you can get the index as:
[tempArray indexOfObject:/the object from result array, one by one/]
contains[c] means search will be case insensitive. For more on predicates: https://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/Predicates/Articles/pUsing.html
EDIT
set the textField's delegate as self. Before that go to YourFile.h, there add UITextFieldDelegate. now in textFieldShouldReturn do this:
- (BOOL)textFieldShouldReturn:(UITextField *)textField {
[textField resignFirstResponder];
NSMutableArray *tempArray = [NSMutableArray arrayWithObjects:@"bat man",@"bat and ball",@"ball", nil];
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF contains[c] %@",textField.text];
NSArray *result = [tempArray filteredArrayUsingPredicate:predicate];
return YES;
}
