i'm trying to make calls from my app, but it seems i can't because the numbers are in india format (example : ٩٦٦٥٩٥٨٤٨٨٨٢) and to make it work , I have to convert this string to arabic format (example : 966595848882)
my code :
NSString *cleanedString = [[ContactInfo componentsSeparatedByCharactersInSet:[[NSCharacterSet characterSetWithCharactersInString:#"0123456789-+()"] invertedSet]] componentsJoinedByString:#""];
NSString *phoneNumber = [#"telprompt://" stringByAppendingString:cleanedString];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:phoneNumber]];
Use NSNumberFormatter with the appropriate locale. For example:
NSString *indianNumberString = #"٩٦٦٥٩٥٨٤٨٨٨٢";
NSNumberFormatter *nf1 = [[NSNumberFormatter alloc] init];
NSLocale *locale = [NSLocale localeWithLocaleIdentifier:#"hi_IN"];
[nf1 setLocale:locale];
NSNumber *newNum = [nf1 numberFromString:indianNumberString];
NSLog(#"new: %#", newNum);
This prints "966595848882".
I'm not 100% certain on the locale identifier above-- hi_IN should be "Hindi India". If that's not correct, use [NSLocale availableLocaleIdentifiers] to get a list of all known locale identifiers, and find one that's more appropriate.
Update: in order to pad this out to nine digits (or however many you want), convert back to an NSString using standard NSString formatting:
NSString *paddedString = [NSString stringWithFormat:#"%09ld", [newNum integerValue]];
The format %09ld will zero-pad out to nine digits.
It's also possible to do this using the same number formatter, converting the number above back into a string while requiring 9 digits. This also gives at least nine digits, with zero padding if necessary:
[nf1 setMinimumIntegerDigits:9];
NSString *reverseConvert = [nf1 stringFromNumber:newNum];

I have number 36381129. I need number 36.381,129
I tried this code, but it doesn't work.
int number = 36381129;
NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init];
[numberFormatter setNumberStyle: NSNumberFormatterCurrencyStyle];
NSString *numberAsString = [numberFormatter stringFromNumber: [NSNumber numberWithInt:number]];
I give this number.
36.381.129,00 $
I think this is BRAZILIAN REAL CURRENCY Format. You have to call this method with your price in float value, and this method returns your string into your format. Like if we pass 123456789, then it will return 123,456,789.00.
//Convert Price to Your Price Format
+(NSString*)convertFormat:(float)value{
NSString * convertedString = [NSString stringWithFormat:#"%.2f", value];
NSString * leftPart;
NSString * rightPart;
if (([convertedString rangeOfString:#"."].location != NSNotFound)) {
rightPart = [[convertedString componentsSeparatedByString:#"."] objectAtIndex:1];
leftPart = [[convertedString componentsSeparatedByString:#"."] objectAtIndex:0];
}
//NSLog(#"%d",[leftPart length]);
NSMutableString *mu = [NSMutableString stringWithString:leftPart];
if ([mu length] > 3) {
[mu insertString:#"." atIndex:[mu length] - 3];
//NSLog(#"String is %# and length is %d", mu, [mu length]);
}
for (int i=7; i<[mu length]; i=i+4) {
[mu insertString:#"." atIndex:[mu length] - i];
//NSLog(#"%d",mu.length);
}
convertedString = [[mu stringByAppendingString:#","] stringByAppendingString:rightPart];
return convertedString;
}

Hope, this is what you're looking for. Any concern get back to me.
Welcome to SO. Your question is pretty vague.
Currency formats depend on the user's locale. It's generally better to either use the default locale of the device, or set a locale, and then let the currency formatter create that string that's appropriate for that locale.
If you set up a hard-coded currency format then it will be wrong for some users. (For example in the US we use a "." as a decimal separator and commas as a grouping symbol. In most of Europe they use a comma as a decimal separator and the period as a grouping symbol. Some countries put the currency symbol at the end of a currency amount, and others put it at the beginning.)
You can use this code:
NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];
[formatter setNumberStyle:NSNumberFormatterCurrencyStyle];
NSString *groupingSeparator = [[NSLocale currentLocale] objectForKey:NSLocaleGroupingSeparator];
[formatter setGroupingSeparator:groupingSeparator];
[formatter setGroupingSize:3];
[formatter setAlwaysShowsDecimalSeparator:NO];
[formatter setUsesGroupingSeparator:YES];
and use it this way:
NSString *formattedString = [formatter stringFromNumber:[NSNumber numberWithFloat:rev];
This is a generic solution and will work for any country according to their grouping separator

I am having difficulties converting NSString's that have numbers into floats or something more useful.
I have tried the following code:
NSString *mystring = #"123"
int currentBidAmount = [myString integerValue];
No problem there.
Then float
NSString *mystring = #"123.95"
float currentBidAmount = [myString floatValue];
Again, no problem
However when myString has three decimals - I get an inaccurate number. For Example:
NSString *mystring = #"1.123.95"
float currentBidAmount = [myString floatValue];
It prints out: 1
Can someone tell me what I am doing wrong here?
The goal is to have two NSStrings - get their values and add them up for a total amount. So I need more accuracy than just I am getting now.
While you can get an NSString integer or floatValue you should use NSNumberFormatterfor that. Why? The decimal and grouping separator varies between countries and the floatValue code does only account for . as decimal separator. So users with a locale using a , are doomed.
How to:
NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init];
float myFloat = [numberFormatter numberFromString:myString].floatValue;
Read up on various settings here: https://developer.apple.com/library/ios/documentation/cocoa/reference/foundation/classes/NSNumberFormatter_Class/Reference/Reference.html
you can't put two commas for a float value
this code works fins:
NSString *example = #"13124.4153";
float floatValue = [example floatValue];
NSLog(#"value = %f", floatValue);
Thanks for the help guys. I managed to solve the problem. The issue was the grouping separator. It separated by leaving a space. So this is why I had inaccurate numbers. Now, since I needed all my numbers to stay in this format but change when I was doing calculations (Adding sums together - I wrote a class method that looks like this:
(NSString *)getDisplayAmountStringWithValue: (NSString *)value Currency: (NSString *)currency
{
NSDecimalNumber *decimalValue = [NSDecimalNumber decimalNumberWithString:[value stringByReplacingOccurrencesOfString:#"," withString:#""]];
if ([decimalValue isEqualToNumber:[NSDecimalNumber notANumber]]){
decimalValue = [NSDecimalNumber decimalNumberWithString:#"0"];
}
NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];
[formatter setNumberStyle:NSNumberFormatterDecimalStyle];
[formatter setGroupingSeparator:#" "];
[formatter setDecimalSeparator:#"."];
[formatter setMaximumFractionDigits:2];
[formatter setMinimumFractionDigits:2];
if ([currency length] > 0){
[formatter setPositivePrefix:[NSString stringWithFormat:#"%#", currency]];
[formatter setNegativePrefix:[NSString stringWithFormat:#"%#-", currency]];
}else {
[formatter setGroupingSeparator:#""];
}
NSString *newNumberString = [formatter stringFromNumber:decimalValue];
return newNumberString;
}
Notice the if statement. I simply remove the space if I don't supply a currency (Which is not needed when adding sums together) - this along with my existing code, works perfectly.
Thanks for all the tips.
I'm trying to parse a NSString with a NSNumberFormatter like following.
NSNumberFormatter *myFormatter = [[[NSNumberFormatter alloc] init];
NSNumber *myNumber = [myFormatter numberFromString:#"42.00000"];
numberFromString returns a NSNumber object in the simulator but not on a device.
The decimals (.00000) are causing the return value to be nil on a device because parsing 42 (without the decimals) works just fine (both in the simulator and on a device).
The reason I'm using a NSNumberFormatter is because is like how it returns nil if the string is not a valid number (which is working against me here :p). NSString doubleValue does not provide this kind of behaviour. Also, NSDecimalNumber decimalNumberWithString doesn't do the job because [NSDecimalNumber decimalNumberWithString:#"4a2.00000"] returns 4.
Any ideas why this would not work on a device?
Is it the locale? I tried setting myFormatter.numberStyle = NSNumberFormatterNoStyle and NSNumberFormatterDecimalStyle but it changes nothing.
As #rmaddy already said in a comment, the decimal separator of NSNumberFormatter is
locale dependent. If you have a fixed input format with the dot as decimal separator,
you can set the "POSIX locale":
NSNumberFormatter *myFormatter = [[NSNumberFormatter alloc] init];
[myFormatter setLocale:[NSLocale localeWithLocaleIdentifier:#"en_US_POSIX"]];
NSNumber *myNumber = [myFormatter numberFromString:#"42.00000"];
Alternatively, you can use NSScanner to parse a double value, as e.g. described
here: parsing NSString to Double
42.00000 is not a string mate, why not #"42.00000"?
I am using NSNumberFormatter to format my numbers to strings.
I have a device with Hebrew (israel) region format (settings->General->International->Region Format).
When I try to format the number 100 for instance I get 100 $.
My goal is to remove the space before the currency sign and get just 100$
I ended up changing positiveSuffix and negativeSuffix properties
by removing the spaces from them
because my NSNumberFormatter is static in my application I set them to nil at the end of each use
static NSNumberFormatter *currencyFormatter;
if (!currencyFormatter) {
currencyFormatter = [[NSNumberFormatter alloc] init];
[currencyFormatter setNumberStyle:NSNumberFormatterCurrencyStyle];
[currencyFormatter setNegativeFormat:#""];
}
// remove spaces at the suffix
currencyFormatter.positiveSuffix = [currencyFormatter.positiveSuffix stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
currencyFormatter.negativeSuffix = [currencyFormatter.negativeSuffix stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
// get the return number
NSString* retNum = [currencyFormatter stringFromNumber:val];
// this code is for the next time using currencyFormatter
currencyFormatter.positiveSuffix = nil;
currencyFormatter.negativeSuffix = nil;
return retNum;
How about just removing all spaces from the string before running it through NSNumberFormatter? (as answered in this question)
NSString *stringWithoutSpaces = [myString
stringByReplacingOccurrencesOfString:#" " withString:#""];
In Java we do this statement to have a $ currency format.
double num1 = 3.99 ;
double num2 = 1.00 ;
double total = num1 + num2;
System.out.printf ("Total: $ %.2f", total);
The result is:
Total: $4.99
//--------------------------------
Now in iOS how can I get same format if I have the following statement :
total.text = [NSString stringWithFormat:#"$ %d",([self.coursePriceLabel.text intValue])+([self.courseEPPLabel.text intValue])+10];
Note:
If I use doubleValue the output always is 0 .
You can do the same thing with NSString:
NSString *someString = [NSString stringWithFormat:#"$%.2lf", total];
Note that the format specifier is "%lf" rather than just "%f".
But that only works for US dollars. If you want to make your code more localizable, the right thing to do is to use a number formatter:
NSNumber *someNumber = [NSNumber numberWithDouble:total];
NSNumberFormatter *nf = [[NSNumberFormatter alloc] init];
[nf setNumberStyle:NSNumberFormatterCurrencyStyle];
NSString *someString = [nf stringFromNumber:someNumber];
Of course, it won't do to display a value calculated in US dollars with a Euro symbol or something like that, so you'll either want to do all your calculations in the user's currency, or else convert to the user's currency before displaying. You may find NSValueTransformer helpful for that.
