In still another embodiment of the present invention, as shown in fig. 2, step S102 may include the steps of:
step S201, searching a class, a classification, a protocol and a C function in a header file of the first edition file through keyword matching and/or format matching, and constructing a first header file list based on a method name in the class, a method name in the classification, a method name in the protocol and a C function name;

In still another embodiment of the present invention, as shown in fig. 3, step S201 may include the steps of:
step S301, searching the range of the class, the classification and the protocol in the header file of the first edition file through keyword matching and/or format matching by using keywords and/or formats for searching the class, the classification and the protocol;
in the embodiment of the present invention, the keywords and/or formats used in matching the keywords and/or formats may be predetermined according to the characteristics of the programming language used in the first edition of file, for example, assuming that the SDK is written in the OC language, the keywords and/or formats used in performing the regular matching may be predetermined according to the characteristics of the OC language, such as in the OC language, "/,/" is an annotation in the OC language; the start @ end of the interface identification class/the end of the classification/protocol identifies the start of the protocol, so that "/,///" can be set as keywords for filtering out invalid annotation information, @ interface and @ end can be set as keywords for searching classes, classifications or protocols, and @ protocol can be set as keywords for searching the protocol.
Before the step, the first version file can be recursively traversed to obtain the addresses of a plurality of header files contained in the first version file, the contents of the plurality of header files are read through the addresses, the contents of each header file are matched through//, and/and other invalid keywords used for matching invalid information, and the matched invalid information is deleted to obtain the residual content; in this step, a regular expression can be used to perform keyword matching and/or format matching by using keywords and/or formats for searching classes, classifications and protocols, and keyword matching is performed in the remaining content by using keywords for matching classes, classifications and protocols such as @ interface, @ protocol, @ end, etc., to obtain the range of each class, the range of classification and the range of protocols;
step S302, respectively searching the method names in the classes, the method names in the classes and the method names in the protocols within the ranges of the classes, the classes and the protocols through keyword matching and/or format matching by using keywords and/or formats used for searching the method names in the classes, the method names in the classes and the method names in the protocols;
in this step, the method names of the classes, and the method names of the protocols may be matched by the keywords for finding the classes, the classifications, and the protocols within the range of the respective classes, the range of the classifications, and the range of the protocols using the keywords and/or formats for finding the method names in the classes, the method names in the classifications, and the method names in the protocols.
Step S303, searching the C function name in other ranges except the range of the class, the classification and the protocol in the header file through keyword matching and/or format matching by utilizing keywords and/or formats for searching the C function name;
in this step, the C function name may be matched by a keyword for finding the C function name in the remaining range except for the range of the class, the classification, and the protocol in the header file.
Step S304, respectively constructing a method list, a classified method list, a protocol method list and a C function list of the class according to the method name in the class, the method name in the protocol and the C function name;
for example, in practical applications, the header file of a first version of the file may include the following:
// class A
/*
The primary function of class A is … …
*/
@interface A:B
+(void)test；
@end
For example, when performing keyword and/or format matching on the header file of the above content, the comments may be identified by regular expression matching "//" and "////", and then the comments are all deleted; identifying three keywords of '@ interface', ': and' @ end 'through regular expressions, identifying a class, and then defining a method name' + (void) test in the range of the class; the method names are the method names in the class, the method list of the class can be obtained by combining the method names, and the classified method list, the method list of the protocol, the C function list and the like can be obtained in the same way.
Step S305, adding a method list of the classification corresponding to the class and a method list of the protocol having the use relation with the class to a method list of the class for each class in the first edition file according to the corresponding relation between the classes and the use relation of the class use protocol in the first edition file;
in practical applications, the first version of the file may include at least one class, each class may have a plurality of corresponding classifications, and each class may use at least one protocol, so that there is a correspondence between the class and the classification, and there is a usage relationship between the class and the protocol used by the class, and further, according to the correspondence between the class and the classification and the usage relationship between the class and the protocol used by the class, for each class in the first version of the file, a method list of the classification corresponding to the class and a method list of the protocol associated with the class are added to the method list of the class.
Step S306, combining the method list of the class and the C function list to obtain the first header file list.
In this step, since the sorted method list corresponding to the class and the method list of the protocol associated with the class have already been added to the method list of the class, the method list of the class and the C-function list can be directly combined to obtain the first header file list.

……
00000000000006b8 t-[ABC startDownload]
00000000000039d8 t-[ABC status]

……
00000000000019b8 t-[ABC(Category)versionChangedByPackageID:]
……
0000000000000000T_test1
0000000000000050T_test2
……
