Making calls and clearing the cache

NSLog (@ "Customer service phone");

Uiwebview*callwebview =[[uiwebview alloc] init];

Nsurl *telurl =[nsurl urlwithstring:@ "tel:400-041-5656"];//looks like tel://or Tel: All right

[Callwebview loadrequest:[nsurlrequest Requestwithurl:telurl];

Remember to add to the view

[Self.view Addsubview:callwebview];

Get the size of the cache file

Because the cache file exists in the sandbox, we can use the Nsfilemanager API to calculate the size of the cache file.

Calculate a single File size

Calculate Directory Size

+ (float) Foldersizeatpath: (nsstring*) path{Nsfilemanager*filemanager=[nsfilemanager Defaultmanager];float foldersize; if ([FileManager Fileexistsatpath:path]) {Nsarray*childerfiles=[filemanager Subpathsatpath:path];for (NSString*filename in Childerfiles) {     nsstring *absolutepath=[path Stringbyappendingpathcomponent:filename];       foldersize +=[fileservice Filesizeatpath:absolutepath];     }  // Implementation of Sdwebimage framework self-calculation cache     foldersize< Span class= "RegExp" >+=[[sdimagecache Sharedimagecache] Getsize]/1024.0/ 1024.0;     return foldersize;  }  return 0;}      

Clean up cache files

Also using the Nsfilemanager API for file operations, the Sdwebimage framework itself implements the cleanup cache operation, which we can call directly.

+ (void) ClearCache: (nsstring*) path{Nsfilemanager*filemanager=[nsfilemanager Defaultmanager];if ([FileManager Fileexistsatpath:path]) {   nsarray *childerfiles=[filemanager Subpathsatpath:path];    for (nsstring * FileName in Childerfiles) {      //if necessary, join the conditions, filter out files that you do not want to delete        nsstring *absolutepath=[path stringbyappendingpathcomponent: FileName];       [filemanager removeItemAtPath: Absolutepath Error:nil];     }  }   [[Sdimagecache Sharedimagecache] cleandisk];}
