Question

The below code i used for formatting the string in textfieldShouldDidEndEditing,

NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];    
[formatter setNumberStyle:NSNumberFormatterDecimalStyle];
long long num =  [textField.text longLongValue];
NSString *formattedOutput = [formatter stringFromNumber:[NSNumber numberWithLongLong:num]];
textField.text = formattedOutput;
[formatter release];

I have an issue in above code is, first time its work normally but when we going back to the textfield , and coming out of it , then the value changes.

For example i entered value for first time is 123456789123456789
and got this output 123,456,789,123,456,789
and now when we re-enter and exit from the textfield with or without editing, i am getting the value is 123.

Thanks In Advance

Answer 1

Of course, because after first call in UITextField is stored 123,456,789,123,456,789, not 123456789123456789

When you are calling second time that method in num will be stored 123.

Try this one:

replace

long long num =  [textField.text longLongValue];

with

long long num =  [[formatter numberFromString:textField.text] longLongValue];
