String search in string array in objective c

BOOL isTheObjectThere = [myArray containsObject: @"my string"];

or if you need to know where it is

NSUInteger indexOfTheObject = [myArray indexOfObject: @"my string"];

I strongly recommend you read the documentation on NSArray. It's best to do that before posting your question :-)

You can use NSPredicate class for searching strings in array of strings.See the below sample code.

NSMutableArray *cars = [NSMutableArray arrayWithObjects:@"Maruthi",@"Hyundai", @"Ford", @"Benz", @"BMW",@"Toyota",nil];NSString *stringToSearch = @"i";NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF contains[c] %@",stringToSearch]; // if you need case sensitive search avoid '[c]' in the predicateNSArray *results = [cars filteredArrayUsingPredicate:predicate];

This is the most efficient way for searching strings in array of strings

NSMutableArray *cars = [NSMutableArray arrayWithObjects:@"Max",@"Hai", @"Fine", @"Bow", @"Bomb",@"Toy",nil];NSString *searchText = @"i"; NSArray *results = [cars filteredArrayUsingPredicate:predicate];// if you need case sensitive search avoid '[c]' in the predicate NSPredicate *resultPredicate = [NSPredicate                                predicateWithFormat:@"title contains[c] %@",                                searchText];searchResults = [cars  filteredArrayUsingPredicate:resultPredicate];
