IOS get local cache file size and erase

Because the project needs to calculate the size of the cache file in the application and cleanup work, do a small module to share, casually say that buy apples or choose a 16g or more so mom will not worry about your memory is not enough oh!

clear Local cache file

+ (void) Clearcachefile

{

nsstring *cachpath = [nssearchpathfordirectoriesindomains(nscachesdirectory, Nsuserdomainmask, YES) objectatindex:0];

nsarray *files = [[nsfilemanager defaultmanager] subpathsatpath: Cachpath];

for (nsstring *filename in files)

{

nserror *error;

nsstring *path = [Cachpath stringbyappendingpathcomponent: fileName];

if ([[nsfilemanager defaultmanager] fileexistsatpath:p Ath])

{

[[nsfilemanager defaultmanager] removeitematpath:p ath error:&error];

}

}

}

calculate local cache file size

+ (double) getcachefilesize

{

nsfilemanager *filemanager = [nsfilemanager defaultmanager];

double fileSize = 0.0;

nsstring *cachpath = [nssearchpathfordirectoriesindomains(nscachesdirectory, Nsuserdomainmask, YES) objectatindex:0];

nsarray *files = [FileManager subpathsatpath: Cachpath];

for (nsstring *filename in files)

{

nsstring *path = [Cachpath stringbyappendingpathcomponent: fileName];

if ([FileManager fileexistsatpath:p Ath])

{

nsdictionary *fileattributes = [FileManager attributesofitematpath:p ath error: Nil];

FileSize + = (double) ([FileAttributes fileSize]);

}

}

return fileSize;

}
