如何将数字转换为指示字符串

Question

我只想知道如何将数字1,2或3转换为第一，第二或第三？ 任何帮助将不胜感激。

Answer 1

试试这个，

- (NSString *)getOrdinalTextFor:(NSInteger)number {

     NSNumber *numberValue = [NSNumber numberWithInteger:number];
     NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init];
     [numberFormatter setNumberStyle:NSNumberFormatterOrdinalStyle];

     return [numberFormatter stringFromNumber:numberValue];
}

Answer 2

看到这个可能对你有帮助，

NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];
    [formatter setNumberStyle: NSNumberFormatterSpellOutStyle];
    NSString* numberString = [formatter stringFromNumber:[NSNumber numberWithInt: 3]];
    NSLog(@"%@",numberString);
