nsnumberformatter

I have a UITextField in my application that is supposed to receive only numeric input from the user. This numeric input is supposed to represent currency (i.e. have only two decimal places), have the default value of 0.00 when nothing has been entered. I also would like to have a "$" sign that is on the far left, with the number right aligned, such that the number moves from right to left like such: e.g. when entering the number "1234.56" . 1. $ 0.00 . 2. $ 0.01 . 3. $ 0.12 . 4. $ 1.23 . 5. $ 12.34 . 6. $ 123.45 . 7. $ 1,234.56 . 8. and so on... I have the UITextField right aligned so that it

I have an NSNumberFormatter which I'm trying to use to generate a whole number of GBP (£) from an NSNumber. I keep getting two decimal places regardless of which incantation I try. My code is: NSNumberFormatter *fmtCurrency = [[[NSNumberFormatter alloc] init] autorelease]; [fmtCurrency setNumberStyle: NSNumberFormatterCurrencyStyle]; [fmtCurrency setGeneratesDecimalNumbers:FALSE]; [fmtCurrency setCurrencyCode:@"GBP"]; [fmtCurrency setCurrencySymbol:@"£"]; txtTotal.text = [fmtCurrency stringFromNumber: result.Bill ]; // this is an NSNumber zpasternack I think you want to call

It seems that the NSNumberFormatter can't parse Euro (and probably other) currency strings into a numerical type. Can someone please prove me wrong. I'm attempting to use the following to get a numeric amount from a currency string: NSNumberFormatter *currencyFormatter = [[[NSNumberFormatter alloc] init] autorelease]; [currencyFormatter setNumberStyle:NSNumberFormatterCurrencyStyle]; NSNumber *currencyNumber = [currencyFormatter numberFromString:currencyString]; This works fine for UK and US currency amounts. It even deals with $ and £ and thousands separators with no problems. However, when I

I'm trying to add a decimal after every 3 characters. (Counting backwards like this: 1,325,541 instead of 1325451.) Here is what I tried: - (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string { NSNumberFormatter *numberFormat = [[NSNumberFormatter alloc] init]; [numberFormat setGroupingSeparator:@","]; [numberFormat setGroupingSize:3]; [numberFormat setNumberStyle:NSNumberFormatterDecimalStyle]; NSNumber *amount = [numberFormat numberFromString:textField.text]; textField.text = [numberFormat stringFromNumber:amount]; return

I am having an issue with an NSNumber variable "num" that is currently containing 0.522000003606 I looked up several other issues on stackoverflow with others having the same issue but nothing. My project is currently using ARC so I think some features are unavailable, that is, unless I disallow ARC within the class I am currently wanting to set the precision of the NSNumber. I understand NSNumberFormatter is the basic setPrecision class function I must use but I am having issues.... Everytime i use NSNumberFormatter, it spits back NULL!!! nowValue = [now objectForKey:@"value"]; // This is
