How to create a TRCurrencyTextField

The component is always created with:

• Currency code: BRL
• Value: 0
• Max digits: 11
• Whitespace close to symbol: true

To create a component, just do what you are used to do:

TRCurrencyTextField *textField = [[TRCurrencyTextField alloc] init];

Change the Value

From R$ 0,00 to R$ 1.234,00, you can do for example:

textField.value = [NSNumber numberWithInt:1234];

Change the Currency Code

From R$ 1.234,00 to $ 1,234.00

textField.currencyCode = @"USD";

Change the Country Code

From $ 1,234.00 to 1 234,00 €

[textField setCountryCode:@"FR"];

It is possible only with set method, because one country has only one currency, but one currency can be used on many countries.

So, you can set only one country, but you can get all of countries which use the currency.

Change the Locale

From 1 234,00 € to US$ 1,234.00

[textField setLocale:@"en_ZW"];

Also, it is possible only with set method.

Change max digits

You can set the maximum of number digits on the text, so to change, for example, from US$ 999,999,999.99 to US$ 999,999.99

textField.maxDigits = 8;

Hide the whitespace close to symbol

Also, you can remove the whitespace close to symbol.

So, from US$ 1,234.00 to US$1,234.00

textField.addWhiteSpaceOnSymbol = NO;
