parsing a URL link into segments

Question

http://180.160.1.140/webapp/camera?id=fksmf84-8493-45u3

How to get this url part fksmf84-8493-45u3?? -- this part is keep changing on run time.

This is what i have tried so far.

NSString *url = @"http://180.160.1.140/webapp/camera?id=";
NSArray *parts = [url componentsSeparatedByString:@"="];
NSString *personID = [parts lastObject];
NSLog(@"My ID: %@", personID);

Answer 1

see:

NSString *url = @"http://180.160.1.140/webapp/camera?id=fksmf84-8493-45u3"; // you forgot to add the id in your test case
NSArray *parts = [url componentsSeparatedByString:@"="];
NSString *personID = [parts lastObject];
NSLog(@"My ID: %@", personID);

The output: My ID: fksmf84-8493-45u3

EDIT:

To Store the data:

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];

[defaults setObject:personID forKey:@"personID"];

To read the data:

 NSString *personID = [defaults objectForKey:@"personID"];

With this method you can easily get the value of the last run. Hope this will help you :) .
