How to Substring a NSString in iOS?

Question

How can I remove all dollar($) symbols from my NSString?

amountDataArray = 
    [[NSMutableArray alloc]
         initWithObjects:@"$ 10", @"$ 20", @"$ 30", @"$ 40", @"$ 50", @"$ 60", nil];

I am showing displaying string in UILabel:

confirm.balanceStr = self.amountLbl.text;

I am also setting amountLbl.text to confirm.balanceStr, but I don't want '$' in my string.

I want to show only amount like 20, 30 , 40 but not with the dollar, like $10, $20,

Answer 1

Try something like this

amountLbl.text = [confirm.balanceStr stringByReplacingOccurrencesOfString:@"$ " withString:@""];

Answer 2

There are several solutions:

1. String operations, if there is no doubt, that the string has the prefix @"$ ":

   NSString *valueString = [dollaredString substringFromIndex:2];

2. Scanning. A little bit more robust, but more work to do.

3. Number formatter.

Build a number formatter for your string and let it make the work. You simply have to confgure it to your format.

Answer 3

confirm.balanceStr = [self.amountLbl.text replaceOccurencesOfString:@"$" 
                               withString:@"" 
                                  options:NULL
                                    range:NSMakeRange(0, [receiver length])];

Try this code...

Answer 4

lbl.text = [[yourStringWithDollor componentsSeparatedByString:@" "] objectAtIndex:1];
