The preferred embodiments of the present invention are illustrated below in conjunction with accompanying drawing, it will be appreciated that preferred reality described herein
Apply example to be merely to illustrate and explain the present invention, be not intended to limit the present invention.
As shown in Figure 1 for one embodiment of the invention Program section detection method flow chart, the method can include with
Lower step S11-S14.
Step S11, runs printf.
Step S12, by the printf call macro.
Step S13, it is described grand by running, obtain current location information.
In this step, the positional information of acquisition can at least include one of following：Filename, class name, function name and generation
Code line number.
Step S14, the positional information is exported by printf.
It is in this step, described that to export the positional information by printf can be by printf outgoing position
The field name of information and the corresponding positional information.
In embodiments of the present invention, printf is run；By the printf call macro；It is described grand by running,
Obtain current location information；The positional information is exported by printf.As can be seen here, embodiment of the present invention modification printing letter
Number, makes printf read the information such as code line number, class name, and when performing printf, in addition to output character, also
Output code line number and class name etc., so conveniently determine the module of the module or error being successfully tested, thus the embodiment of the present invention
Can realize detecting the purpose whether certain section of code runs succeeded exactly.
Can be logical by running the grand acquisition current location information in step S13 in an optional embodiment
Cross and run described grand, the system information of acquisition compiling system.
The method implementation process of program segment detection of the invention is discussed in detail below by a specific embodiment.Such as Fig. 2
The flow chart of the method for another embodiment of the present invention Program section detection is shown, the method may comprise steps of S21-
S24。
Step S21, runs printf.
Step S22, by the printf call macro.
Step S23, it is described grand by running, obtain the system information of compiling system.
Step S24, by the field name and the corresponding positional information of printf output position information.
In this step, the positional information at least includes one of following：Filename, class name, function name and code line number.
, it is necessary to this output information is added in the place of test printing in specific code, content information can be defined with oneself,
Which viewcontroller the inside such as output is currently at, inside which method of this viewcontroller,
Whole file which, can oneself definition：
#define log(fmt…)
NSlog ((@" [filenames:%s] n " " [function name:%s] n " " line number:%d " n fmt), _ file_,
_function_,_line_)
#define log(…)
The embodiment of the present invention changes printf, printf is read the information such as code line number, class name, and perform
During printf, in addition to output character, output code line number and class name etc. are gone back, so conveniently determine the module being successfully tested
Or error module, thus the embodiment of the present invention can realize detecting the purpose whether certain section of code runs succeeded exactly.
