Convert nsdictionary to Object Class Object

Method 1:

Use the objective-C nsobject built-in method

Setvaluesforkeyswithdictionary: dict

If the key in nsdictionary has the same attribute name as the object class object, set the value of the key to the attribute corresponding to the object class.

- (instancetype)initWithDict:(NSDictionary *)dict{    if (self = [super init]) {        [self setValuesForKeysWithDictionary:dict];    }    return self;}
