how to remove characters from end of the NSString till "/"

I have a string like this @"Root/dbo-NewsLocation/Item 1/dbo-Relator-test/Item 1/Item 1"

When user taps on back button I need to remove @"/Item1" at the end of above string.

I am not able to remove @"Item1" If I do the stringByReplacingOccuranceOfString by using below code it remove all @"Item1" using the below code.

NSString *str1=self.lblCIPath.text;
        NSRange range = [str1 rangeOfString:@"/" options: NSBackwardsSearch];
        NSString *newString = [str1 substringFromIndex:(range.location)];
        self.lblCIPath.text=[self.lblCIPath.text stringByReplacingOccurrencesOfString:newString withString:@""];

I will be thankful if anyone can suggest me the way to delete the last componentPath from NSString.

As Mathieu Meylan suggested you can use stringByDeletingLastPathComponent, or you can simply adjust your code to use substringToIndex instead of substrinFromIndex as follows:

NSString *str1=self.lblCIPath.text;
NSRange range = [str1 rangeOfString:@"/" options: NSBackwardsSearch];
NSString *newString = [str1 substringToIndex:(range.location)];

Final result will be the same: Root/dbo-NewsLocation/Item 1/dbo-Relator-test/Item 1

Have you tried the method stringByDeletingLastPathComponent ?

NSString *updatedPath = [myFullPath stringByDeletingLastPathComponent];
