I'm trying to detect if an entry in a uitextfield is a number or not
but isnan does not seem to work.
NSString * bLong = [NSString stringWithFormat:@"%@",maLong.text];
NSString * bLat = [NSString stringWithFormat:@"%@",maLat.text];
if(isnan([bLat floatValue]) || isnan([bLong floatValue])){
return;
}
What am I doing wrong here?
