如何在Xcode调试器中查看NSDictionary变量的内容?

在 Xcode 调试器中查看 NSDictionary 变量的内容的方法是:

  1. 在 Xcode 的调试控制台中键入以下命令:po dictionaryObjectvar employees = ["Alice": "Software Developer", "Bob": "Business Analyst"]您可以在控制台中键入以下命令:po employees输出:{ Alice: "Software Developer", Bob: "Business Analyst" }var dictionaries = [["Name": "Alice", "Age": 27], ["Name": "Bob", "Age": 32]]您可以在控制台中键入以下命令:po dictionaries输出:["{\"Name\":\"Alice\",\"Age\":27}","{\"Name\":\"Bob\",\"Age\":32}"]var nestedDictionary = ["Dictionary": ["Key1": "Value1", "Key2": "Value2"], ["Array": [1, 2, 3]] ]您可以在控制台中键入以下命令:po flattened(nestedDictionary)输出将显示如下内容:{"Dictionary":["Key1":"Value1","Key2":"Value2"],"Array":[1,2,3]}
  2. 在控制台中运行此命令,输出对象的类型和值。例如,对于以下声明的 NSDictionary:
  3. 如果键名包含空格或其他特殊字符,您可以将键名和类型用引号引起来。例如:
  4. 如果字典中有嵌套字典或数组,请使用 flattened 操作符将其展开,以便查看所有的键值对:
