Step a to step c extracts the title of image resource, and the name of image resource is referred to as key, the attribute information (example of image resource
Such as, position is quoted) as value, it generates the second dictionary (i.e. CodeReferDic).For example, the second dictionary can be as follows:
Step s5, the first dictionary is traversed, checks that its key whether there is in the second dictionary, if it exists the image to be used
Resource, there is no then carrying out suffix match, the image resource in suffix match is labeled as the image resource that can be used, and direct
Match and suffix match all miss image resources are recorded as the image resource being not used by.
Specifically, if the first dictionary includes whether to be used attribute (i.e. used) and reference position attribution (i.e. refs),
Then for being determined as the image resource used, used can be labeled as YES；For the image resource for being determined as to be used,
Its used can be labeled as Maybe [N]；For being determined as the image resource being not used by, used can be labeled as NO.

The dictionary (i.e. UnUsedDic) of the image resource used.
For example, above-mentioned usedDic can be as follows:
For example, above-mentioned UnUsedDic can be as follows:
It should be noted that exist in the second dictionary with the splicing symbol ending such as %, %s and %d key when, can be with
The splicing symbol in the key is removed, regenerates third dictionary, and the key in the first dictionary is matched with third dictionary.Example
Such as, " ' aaa%@': { ... } " becoming " ' aaa ': { ... } ".
Above-mentioned suffix match may include steps of: each of first dictionary of traversal key (i.e. key), initial long
Degree is M, first removes its last position, if the position M-1 of the key is present in third dictionary, labeled as Mabe [1], otherwise after
It is continuous to remove a bit comparison, when removing digit more than or equal to M/2, stop suffix match, label used is NO.
For example, there are following codes in source code: [UIImage imageNamed:[NSString
StringWithFormat:@" aaaaaa%@.png ", ISPHONE? @" _ s "]
By obtaining following character string: aaaaaa%@.png after regular expression matching；
Characteristics of image is gone to generate the second dictionary (i.e. CodeReferDic): ' aaaaaa%@': { ... } }；
Suffix feature is gone to generate third dictionary (i.e. perfixCodeReferDic): { ' aaaaaa ': { ... } }
If there is image resource aaaaaabcd, first whether inspection aaaaaabcd is in CodeReferDic for meeting, if it exists then
Directly to match, otherwise remove last position and obtain aaaaaabc, and check aaaaaabc whether there is in
PerfixCodeReferDic is labeled as Maybe [3], really if being present in perfixCodeReferDic after removing three
The fixed image resource is the image resource being likely to be used.
