ios - Formating a single textfield so that it display is different to all the others -

-

how set currency in text field display localized currency, leading 0. if types in 16.25 pence formated 0.1625£ respectively. using delegation , formating text fields numbers can passed in, field should localized.

- (bool)textfield:(uitextfield *)textfield shouldchangecharactersinrange:(nsrange)range     replacementstring:(nsstring *)string  {    // first, create text end in     input field if you'll return yes:     nsstring *resultstring = [textfield.text stringbyreplacingcharactersinrange:range    withstring:string];     // now, validate text , return no if don't it'll contain. // accomplish trying convert number , see if worked.     nsnumberformatter *numberformatter = [[nsnumberformatter alloc] init];    [numberformatter setnumberstyle:nsnumberformatterdecimalstyle];     nsnumber* resultingnumber = [numberformatter numberfromstring:resultstring];     //[numberformatter release];     return resultingnumber != nil;

i not want change, formats fields. want textfield1 have relevant format,how go doing this, think lies in viewdidload method , setting text property localized floating point, cant seem work out how it.

you can specify textfield want format in delegate method above.

if (textfield == textfield1) {     // something....  } else {    // whatever want other text fields  }

for floating point formatting, use -

[mytextfield settext:[nsstring stringwithformat:@"%.2f", myfloat]];
