Returning a Formatted NSString From NSNumber?

Question

I have created a database that contains a number of values against other data.

Typically the Number will be in the form of: 40000 or similar. I would like to display this in a form as a NSString like '40,000'.

How would this be best achieved ?

Answer 1

Write a category for NSNumber. Or get a C manual and check at all the ways to format a number in C, which all applies to +NSString stringWithFormat as well.

Answer 2

You can set format like this

NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init];
[numberFormatter setPositiveFormat:@"##,##,###"];      
NSString *formattedNumberString = [numberFormatter 
  stringFromNumber:[NSNumber numberWithFloat:1234567]];
NSLog(@"formattedNumberString: %@", formattedNumberString);

Answer 3

尝试这个。

    NSString *formatedString=[NSString stringWithFormat:@"%@",yourValueFromDatabase];

Answer 4

Simply do as follows:

   NSNumber *YourNumber = [NSNumber numberWithInt:123456789];
   NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];
   [formatter setNumberStyle:NSNumberFormatterDecimalStyle];
   NSString *FormattedNumber = [formatter stringForObjectValue:YourNumber];
   NSLog(@"value : %@", FormattedNumber);

or

NSString * formatedString = [NSNumber stringValue]; 

Answer 5

  NSString *str = [NSString stringWithFormat:@"%@",yourNumber];

If you want for thousand of records you can use for loop.

Hope this will help :)
