#"23.0984" USD to #"23.09 USD" - ios

Question

I am sending URLRequest as mentioned below.
NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *balanceString = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
And I am getting #"23.0984 USD" in balanceString
Then I would like to display it on uilabel.tex= 23.09 USD Please help me

Answer 1

NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *balanceString = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
float amount = [balanceString floatValue]; // This will return 23.0984 as a float
NSString *formattedAmount = [NSString stringWithFormat:#"%01.2f USD", amount];

Answer 2

Then something like this should work:
NSString * inp = #"29.2994 USD";
// Initialize a scanner to process the input
NSScanner * scanner = [NSScanner scannerWithString:inp];
// Pull out a floating point value
float v;
[scanner scanFloat:&v];
NSCharacterSet * ws = [NSCharacterSet whitespaceAndNewlineCharacterSet];
// scan through the whitespace after the float
[scanner scanCharactersFromSet:ws intoString:nil];
NSString * currency;
[scanner scanUpToCharactersFromSet:ws intoString:&currency];
// write out value:
uilabel.text= [NSString stringWithFormat:#"%.2f %#",v,currency];

Answer 3

There might be easier ways.. But this should work..
NSString *originalString = #"23.0984 USD";
NSString *numberString = [originalString stringByReplacingOccurrencesOfString:#" USD"
withString:#""];
float number = [numberString floatValue];
NSString *changedString = [NSString stringWithFormat:#"%.2f",number];
NSLog(#"ChangedString : %# USD",changedString);
EDIT: This answer is already accepted. But I think a better method to get number from string is to search for spaces rather than replacing hardcoded string #" USD".
NSString *originalString = #"23.0984 USD";
NSString *numberString = nil;
NSArray *parts = [originalString componentsSeparatedByString:#" "]; //space
if(parts && [parts lenght]){
numberString = [parts objectAtIndex:0];
}
float number = [numberString floatValue];
NSString *changedString = [NSString stringWithFormat:#"%.2f",number];
NSLog(#"ChangedString : %# USD",changedString);
