/// below two methods, all of which belong to the KVC method

//KVC is Cocoa 's big trick! To set the value of an object property indirectly

// program execution, dynamically set the value of the object property, do not care about How to define it in the . h

// as long as the object has attributes (either in. h or in. m defined properties ), it can read / set!

// This way, a bit against the development principles of the program!

// dictionary turn model setvaluesforkeyswithdictionary

// model to dictionary Dictionarywithvaluesforkeys

Suppose Self.person is a person object defined,

The property of the person object has name,age,height, and the private property has weight

Then the object to dictionary is as follows:

nsdictionary *dict = [self. Person dictionarywithvaluesforkeys:@[@ "name"@ "age" , @ "Weight",@ "height"]; Parameter array is the name of the property

The dictionary to model is as follows

[Self.person setvaluesforkeyswithdictionary:d ICT];
