In the present embodiment, can be determined according to the attribute information of chat record user chat when some custom so that really
The data that fixed data to be deleted and needs retain.Number to be deleted can be determined in implementation process by following three aspects
According to：
First aspect, the chatting object not chatted for a long time is pulled, will be chatted corresponding to the chatting object not chatted for a long time
Its subrecord is defined as data to be deleted.
Second aspect, a concept " replying delay number " is set.Because some chatting objects still can chat once in a while, still
User may not be needed to preserve chat subrecord corresponding to these chatting objects.User replies message faster theory under many circumstances
Bright user more payes attention to this chatting object, based on this, can set a reply delay duration, such as three minutes, during reply
Between then recorded once more than this delay duration, then the threshold value in a period is set, such as 10 times in one week, when user returns
" the replying delay number " of some multiple chatting object exceedes this threshold value within the period, then automatically that this chatting object is corresponding
Chat subrecord be defined as data to be deleted.
The third aspect, situation one concept " group chat is actively spent " of setting for chatting object for a group, statistics one
User number of make a speech in some group accounts for the percentage always chatted in the section time, and this percentage represents the product of user's group chat
Extremely, a threshold value, such as 10% are set, when actively degree is less than this threshold value for this, chat corresponding to the chatting object
Record is defined as data to be deleted.
The aggregation of data to be deleted that the aspect of the above three determines constitutes the data to be deleted of the present embodiment.
Step S303, delete the data to be deleted.
Here, the step S303 can be realized by terminal.
In the present embodiment, user can set the cache threshold of a social networking application, data cached when social networking application
When the space size of occupancy reaches this cache threshold, automatically according to the Notes of Key Data to be deleted of determination in terms of three above to use
Family allows user to carry out selection and cleared up, and so reaches the purpose of cleaning rubbish, also saves the message that user is not desired to cleaning.
In data-erasure method provided in an embodiment of the present invention, first when data cached the first shared sky of itself
Between size when being more than first threshold, obtain the chat record of social networking application and the attribute information of the chat record；Then basis
The attribute information of the chat record determines data to be deleted in the chat record；The data to be deleted are deleted again.
The data for wanting to retain and data to be deleted can be so selected according to the chat record Automatic sieve of user, and delete what is filtered out
Data to be deleted, and then lift the memory space of terminal.
Based on foregoing embodiment, the embodiment of the present invention provides a kind of data-erasure method again, and Fig. 4 is the embodiment of the present invention
The implementation process schematic diagram of data-erasure method, as shown in figure 4, the described method comprises the following steps：
Step S401, terminal receive user and start the operational order that intelligence deletes data function.
Here, user can start intelligence deletion data function in several ways, such as：Interface can be set by clicking on
Intelligence delete the button of data function, intelligence can also be started by the shortcut that pre-sets and delete data function, example

It is exhaustive.
Step S402, the terminal export the setting interface of intelligence deletion data function based on the operational order.
Here, Fig. 5 is the setting interface schematic diagram that the embodiment of the present invention intelligently deletes data function, as shown in figure 5, user
Can be by setting intelligence to delete the parameter information of data function in terms of following four：
The first, the chat subrecord for deleting the chatting object for how long not carrying out chat is set by 501, that is,
First duration threshold value is set.For example, the chat record deleted and do not carried out chat for 7 days can be set.
2nd, set to delete by 502 and the chat subrecord that time delay number exceedes certain threshold value is replied in a period of time, also
It is that the second preset duration, the second duration threshold value and the first frequency threshold value are set.Exceed for example, can set and time delay is replied in 7 days
The chat subrecord of chatting object of the number of 20 minutes more than 5 times.
3rd, set speech number in deletion a period of time to be less than the chat record of certain threshold value by 503, that is, set
First preset duration and the second frequency threshold value.For example, the chat note for group of the number less than 10 times of being made a speech in 7 days can be arranged on
Record.
4th, keyword is set by 504, when including the keyword in a certain section of chat content, does not delete the chat
Content.For example, key can be set to include：Borrow, go back, have a meeting.
In addition, four aspect users can arbitrarily select to determine data to be deleted for the use of at least one above.
In the present embodiment, it is assumed that have selected first and third, four to determine data to be deleted.
It should be noted that described set the option for needing to be configured in interface, terminal can export default value, such as
Acquiescence deletes the chat record for not carrying out chat for 5 days.
Step S403, setting operation of the terminal based on user obtain the parameter information that intelligence deletes data function.
Step S404, the terminal judge whether data cached the first shared space size of itself is more than the first threshold
Value.
Here, if first space size is more than the first threshold, into step S405；If described first is empty
Between size be not more than the first threshold, terminate flow.
In other embodiments, in order to which more intelligent carries out deletion data, if first space size is more than described
