Class methods for encapsulating caches

Get disk size

//Get Hard disk size+(cgfloat) getdisksize{nsstring*libpath = [Nssearchpathfordirectoriesindomains (nslibrarydirectory, Nsuserdomainmask, YES) ObjectAtIndex:0]; NSLog (@"%@", LibPath); //Initialize File ManagerNsfilemanager *manager =[Nsfilemanager Defaultmanager]; //get all paths under LibNsarray *liballpath =[manager Subpathsatpath:libpath]; Nsinteger size=0;  for(NSString *pathinchLiballpath) {        if(! [Path containsstring:@"Preferences"]) {            //stitch The path together in fullNSString *patha =[LibPath Stringbyappendingpathcomponent:path]; //get all information about a fileNsdictionary *fileattri =[manager Attributesofitematpath:patha Error:nil]; //Get File SizeSize + = [fileattri[@"nsfilesize"] IntegerValue]; }    }    returnsize/1024.0/1024.0;}

Ways to clear the cache

//Clear Cache+ (void) cleardisk{NSString*libpath = Nssearchpathfordirectoriesindomains (Nslibrarydirectory, Nsuserdomainmask, YES) [0]; //Initialize File ManagerNsfilemanager *mgr =[Nsfilemanager Defaultmanager]; //get all paths under LibNsarray *liballpath =[Mgr Subpathsatpath:libpath];  for(NSString *pathinchLiballpath) {        if(! [Path containsstring:@"Preferences"]) {            //stitch The path together in fullNSString *patha =[LibPath Stringbyappendingpathcomponent:path]; //Remove files from[Mgr Removeitematpath:patha Error:nil]; }    }}

The garbage size is displayed in the cell that clears the cache when called

-(UITableViewCell *) TableView: (UITableView *) TableView Cellforrowatindexpath: (Nsindexpath *) indexpath{StaticNSString *cellidentifier =@"Cell"; UITableViewCell*cell = [TableView dequeuereusablecellwithidentifier:@"Cell"]; if(Cell = =Nil) {Cell=[[UITableViewCell alloc] initwithstyle:uitableviewcellstylevalue1 reuseidentifier:cellidentifier]; }    Switch(indexpath.row) { Case 0: Cell.textLabel.text=@"Event Collection";  Break;  Case 1: Cell.textLabel.text=@"Movie Collection";  Break;  Case 2: {cell.textLabel.text=@"Clear Cache"; NSString*size = [NSString stringWithFormat:@"%.2fm", [Cleardiskmanager Getdisksize]]; Cell.detailTextLabel.text=size;  Break; }        default:             Break; } Cell.backgroundcolor=[Uicolor Cyancolor]; returncell;}

Clean up cache when clicking cell
