Remove last "/" from string in Iphone SDK - iphone

Question

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??

Answer 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];

Answer 2

try this code ...
NSString *Mystring = #"http://feedproxy.google.com/~r/MakePartsFast/~3/1dZEOLADapg/";
if ([Mystring isEqualToString:#""]||[Mystring isEqual:nil]) {
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);
}

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];

Answer 4

I think you need to encode the string like:
NSString *encodedString = [Mystring stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

NSString * Mystring=#"http://feedproxy.google.com/~r/MakePartsFast/~3/1dZEOLADapg/";
[alfa substringToIndex:alfa.length-1];
