use this : 

for (NSString * string in yourArray) {
    if ([string isEqualToString:textField.text])
    {       
      NSLog(@" They are equal");        
    }
    else
    {
      NSLog(@" They are not");
    }
}

Use isEqualToString: method for campare two String.

for (int i=0; i<[array count]; i++) {
    NSString * string = [array objectAtIndex:i];
    i if (string isEqualToString:textField.text)
    {       
      NSLog(@"Equal");        
    }
    else
    {
      NSLog(@"Not Equal");
    }
}

Use compare: method.

for (int i=0; i<[yourArray count]; i++) {
    NSString * string = [yourArray objectAtIndex:i];
    if ([textfield.text compare:string]) {
        NSLog(@"yes");
        break;
    }
}

I think it will be helpful to you.

If you have an NSArray of NSString's and you just want to see whether or not the text field string is in the array you can use:

NSString *textFieldString;   // Contents of my text field
NSArray *myArray;            // Array to search
BOOL stringMatches = [myArray containsObject:textFieldString];

If you instead want to know the index of the string in the array use:

NSUInteger index = [myArray indexOfObject:textFieldString];

If index == NSNotFound the array does not contain the text field string.
