Hi,
Here is the way to separate numbers from a mixed character string. For this , anybody can use "NSScanner" in their own way. I use this one to filter numbers from the given input string. Please have look ...
For Example :
NSString *string = @"45#%ds32(())_*x 34";
NSMutableString *newStrStrip = [NSMutableString
stringWithCapacity:newStrStrip.length];
NSScanner *scanner = [NSScanner scannerWithString:string];
NSCharacterSet *numbers = [NSCharacterSet
characterSetWithCharactersInString:@"0123456789"];
while ([scanner isAtEnd] == NO)
{
NSString *buffer;
if ([scanner scanCharactersFromSet:numbers intoString:&buffer])
{
[newStrStrip appendString:buffer];
}
else
{
[scanner setScanLocation:([scanner scanLocation] + 1)];
}
}
NSLog(@"OUTPUT : %@", newStrStrip); // "OUTPUT : 453234"
