有時候需要刪除所有檔案與資料夾 (Delete all File and Folder)，來重新下載檔案，因為有可能下載來的檔案是壞掉的。
原來只要一行程式碼就能搞定，之前我還想說要跑資料夾下的所有檔案來一一刪除，會使用這篇列出檔案名稱 (List File Name)。

// Documents 資料夾
NSArray *paths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsPath = [paths objectAtIndex:0];
NSString *folderPath = [documentsPath stringByAppendingPathComponent:@"Resource"];
NSError *error = nil;
BOOL isSuccess = [fm removeItemAtPath:folderPath error:&error];
if (!isSuccess || error) {
// something went wrong
}
執行後，結果為：

隨意留個言吧：）～
