Remove last "/" from string in Iphone SDK

I have a string like:

http://feedproxy.google.com/~r/MakePartsFast/~3/1dZEOLADapg/

I want to use this string to load html page. But because of "/" at last in string, I get the URL is as null.

my code is as follow:

NSURL *ur=[NSURL URLWithString:Mystring];
        NSLog(@"%@",ur); //getting null value

    NSURLRequest *requestObj = [NSURLRequest requestWithURL:ur];

        NSLog(@"%@",requestObj);

So, How can i remove this last "/" from string??

        NSLog(@"\n\n String is NULL");
    }
    else {
        NSString *TempURl = [Mystring substringToIndex:[Mystring length]-1];

        NSString *urlstr =[TempURl stringByReplacingOccurrencesOfString:@" " withString:@""];
        urlstr =[urlstr stringByReplacingOccurrencesOfString:@"\n" withString:@""];

        urlstr =[urlstr stringByReplacingOccurrencesOfString:@"\t" withString:@""];
        [urlstr retain];

        NSURL *ur=[NSURL URLWithString:urlstr];
        NSLog(@"%@",ur); //now get string value here

        //        NSURLRequest *requestObj = [NSURLRequest requestWithURL:ur];
        //        
        //        NSLog(@"%@",requestObj);

I think you need to encode the string like:

NSString *encodedString = [Mystring stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

If you are sure that you need to remove the last character from string in every case, then you can get a newString as 

NSString *newString = [oldString substringToIndex:[oldString length]-1];

Are you sure it's because of the last '/'? Could it be because of the '~' character in the middle?

Whichever way, to check for the last character, simply do

unichar last = [urlString characterAtIndex:urlString.length - 1];
if (last == '/')
    urlString = [urlString substringToIndex:urlString.length - 1];
