stringWithFormat：与predicateWithFormat：

Question

使用from __future__ import print_function xs = [] for i in xrange(1, 11, 2): xs.append(i) print(*xs) 时，我希望尽可能重复使用我的论点。像这样：

NSString stringWithFormat:

使用NSPredicate这不起作用：

NSString *s = [NSString stringWithFormat:@"%1$@ = %2$@ OR (%1$@ = %2$@ AND %3$@ = %4$@)",
                  someValue, @YES,
                  anotherValue, @NO];

我需要做的是：

NSPredicate *p = [NSPredicate predicateWithFormat:@"%1$K = %2$@ OR (%1$K = %2$@ AND %3$K = %4$@)",
                              someKey, @YES,
                              anotherKey, @NO];

我知道NSPredicate仅支持％K（predicateWithFormat vs stringWithFormat: is the former supposed to do the same as the latter?）并且存在一些差异，但输入两次仍然很难看。还有其他选择吗？
