问题描述
我有一个 NSMutableDictionary ，带有字符串键，每个键都有自己的数组。我想按字母顺序用键值重新排序字典。我怎么能这样做？
I have a NSMutableDictionary with string keys and every key has its own array. I want to re-sort the dictionary with keys value alphabetically. How can I do this?
推荐答案
根据定义，字典是未排序的。
A dictionary is unsorted by definition.
为了按特定顺序迭代键，您可以对包含字典键的数组进行排序。
For iterating over the keys in a specific order, you can sort an array containing the keys of the dictionary.
NSArray *keys = [theDictionary allKeys];
NSArray *sortedKeys = [keys sortedArrayUsingSelector:@selector(compareMethod:)];
还有其他几个已排序...... 方法，例如使用 NSComparator 进行排序。看看。
There are several other sorted... methods, e.g. sorting with a NSComparator. Have a look here.
