Preventing decimals with NSNumberFormatter

I think you want to call setMaximumFractionDigits with zero.

NSNumberFormatter *fmtCurrency = [[[NSNumberFormatter alloc] init] autorelease];
[fmtCurrency setNumberStyle: NSNumberFormatterCurrencyStyle];
[fmtCurrency setGeneratesDecimalNumbers:NO];
[fmtCurrency setCurrencyCode:@"GBP"];
[fmtCurrency setCurrencySymbol:@"£"];

NSNumber* myNumber = [NSNumber numberWithFloat:12.34];
NSString* myString = [fmtCurrency stringFromNumber:myNumber];
NSLog( @"the number is %@", myString );

[fmtCurrency setMaximumFractionDigits:0];
myString = [fmtCurrency stringFromNumber:myNumber];
NSLog( @"now it's %@", myString );  


2011-07-25 01:05:39.823 FormatterTest[841:707] the number is £12.34
2011-07-25 01:05:39.824 FormatterTest[841:707] now it's £12

You can try the following

[fmtCurrency setGeneratesDecimalNumbers:NO];
[fmtCurrency setMaximumFractionDigits:0];

or

Get intValue from the NSNumber as suggested by @Praveen
