如何将 NSNumber "1234567 " 转换为 "12,34,567"？
I have used the NSNumberFormatter for this,but couldn't get the desired result.
我为此使用了 NSNumberFormatter，但无法获得所需的结果。
I am doing like this
我这样做
NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];
[formatter setNumberStyle:NSNumberFormatterDecimalStyle];
NSString *formattedString = [formatter stringFromNumber:[NSNumber numberWithFloat:1234567]];
NSLog(@":%@",formattedString);
Output: 1,234,567
输出：1,234,567
Desired Output: 12,34,567
期望输出：12,34,567

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

NSNumber *number = [NSNumber numberWithInteger:1234567];
NSNumberFormatter *formatter = [NSNumberFormatter new];
[formatter setNumberStyle:NSNumberFormatterDecimalStyle];
NSLog(@"%@", [formatter stringFromNumber:number]);
[formatter release];
