The denotation approach of aforesaid iOS equipment, in the step (3), generate random number after, described random number is stored in the index of the buffer memory of operating system and pasting boards.
The denotation approach of aforesaid iOS equipment wherein, after random number is stored in the index of pasting boards, but is YES with the persistence setup of attribute of described index.
The denotation approach of aforesaid iOS equipment wherein, after maximum values is stored in the operating system pasting boards with occurrence number with unappropriated index, but is YES with the persistence setup of attribute of described index.
Adopt the method for the invention, can be in the situation that does not read hardware information unique sign iOS equipment, and have fault-tolerance.Fault-tolerance be mainly manifested in device flag to be found by redundant storage in a plurality of keys of system's pasting boards, get the maximum value of occurrence number as the unique sign of equipment, avoided because the situation that some accidents cause the part key assignments to lose or be tampered.Because device id is to be buffered in system's pasting boards, even application software still can remain after deleted, after being installed again, the application software of other new installations or this application software still may be read into original device id.
Description of drawings
Fig. 1 is the denotation approach process flow diagram of iOS equipment in the embodiment.
Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in detail.
As shown in Figure 1, do not read hardware information sign iOS device, method in the present embodiment, may further comprise the steps:
(1) searches whether buffer memory is crossed this iOS device id in the iOS device operating system buffer memory, in this way, then use this iOS device id, finish; Otherwise execution next step.
(2) identifier udidkey of definition can be character string or numeric type, is assigned to the value of an agreement of udidkey, take character string as example: " com.gridsum.tracker.udid ".
The purpose of definition identifier udidkey is for the subsequent step storage and searches random number uuid that because system's pasting boards is a public place, other programs also can be accessed, so identifier udidkey also is in order to isolate with other programs.
(3) in system's pasting boards, about definite value+" 0 " of searching identifier occurrence number not worth any more than in " N " is namely found out the maximum value of occurrence number in the value of com.gridsum.tracker.udid0 to com.gridsum.tracke r.udidN.Simultaneously, search M unappropriated index.
If do not find unappropriated index, then generate a random number uuid, be stored among the udidkey+ " 0 ", this random number uuid is unique sign of iOS equipment, finishes.After generating random number uuid, described random number is stored in the index of the buffer memory of operating system and pasting boards, but and is YES with the persistence setup of attribute of described index.
If find unappropriated index, then be stored in system's pasting boards with this index value that occurrence number is maximum, but and the persistence attribute (persistent) of system's pasting boards be set to YES.This is can to get off by persistence for the value that the system that is stored in is pasted in the version, otherwise data will be cleared behind the powered-down.
Seeking unappropriated index quantity M can be one, also can be two or more.In order to strengthen fault-tolerance, avoid losing or being tampered because certain operations causes index value, preferred, select more than two unappropriated index to store the maximum value of occurrence number, carry out redundancy backup.Described N and M are positive integer, and be preferred, when M=1, and N 〉=50; When M=2, N 〉=100; Be N 〉=50 * M.In the present embodiment, M=2, N=100.
For example: suppose that the data mode in the present system pasting boards is as follows:
| Key | Value |
| com.gridsum.tracke r.udid0 | 1234567 |
| com.gridsum.tracke r.udid1 | 1234567 |
| com.gridsum.tracker.udid2 | abcdefg |
| com.gridsum.tracke r.udid3 | 1234567 |
| com.gridsum.tracke r.udid5 | 1234567 |
The value that occurrence number is maximum in system's pasting boards is that 1234567, two unappropriated index are respectively com.gridsum.tracker.udid4 and com.gridsum.tracker.udid6.
After executing this step, the data mode in system's pasting boards is as follows:
| Key | Value |
| com.gridsum.tracker.udid0 | 1234567 |
| com.gridsum.tracker.udid1 | 1234567 |
| com.gridsum.tracker.udid2 | abcdefg |
| com.gridsum.tracker.udid3 | 1234567 |
| com.gridsum.tracker.udid4 | 1234567 |
| com.gridsum.tracker.udid5 | 1234567 |
