Last active December 27, 2015 15:59

Check a string for a whitespace by creating an NSArray from an NSString separated by a whitespace. If this count is greater than one, then there is at least 1 whitespace.

	NSArray *checkPasswordForWhitespace = [password.text componentsSeparatedByString:@" "];

	NSLog(@"%@", checkPasswordForWhitespace);

	if ([checkPasswordForWhitespace count] > 1) {

	UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Whitespace" message:@"Please remove the whitespace from your password." delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
	[alert show];

	return;

	NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];

appyaaron / Setting parameters on an NSString (iOS)

Last active December 26, 2015 15:49

A nice and simple way to get the characters in-between a start character and an end character using NSRange. Replace cell.text with your string.

	NSString *param3 = nil;
	NSRange start3 = [cell.text rangeOfString:@"thestartcharacterhere"];
	if (start3.location != NSNotFound)
	{
	param3 = [cell.text substringFromIndex:start3.location + start3.length];
	NSRange end3 = [param3 rangeOfString:@"theendcharacterhere"];
	if (end3.location != NSNotFound)
	{
	param3 = [param3 substringToIndex:end3.location];
	}
