List all the store file in directory or delete the file in iOS ( Swift).

List all file from local directory

Sometimes we need to show all stored file in the application so a user can easily see their file or can delete this file also.Here I have taken the example of showing pdf file and delete this file.

Steps are.

1: List all stored file.

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSArray * directoryContents =  [[NSFileManager defaultManager]
                                    contentsOfDirectoryAtPath:documentsDirectory error:&error];

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

NSString *documentsDirectory = [paths objectAtIndex:0];

NSArray * directoryContents = [[NSFileManager defaultManager]

contentsOfDirectoryAtPath:documentsDirectory error:&error];

2: here I am listing only pdf file.

 for (int i = 0;i<directoryContents.count;i++){
        NSString *data = directoryContents[i];
        if ([data containsString:@".pdf"]){
            invoiceListData[i] = data;
        }
    }

for (int i = 0;i<directoryContents.count;i++){

NSString *data = directoryContents[i];

if ([data containsString:@".pdf"]){

invoiceListData[i] = data;

}

3: For deleting the file.

 NSString *fileName = [invoiceListData objectAtIndex:[indexPath row]];
            
            NSFileManager *fileManager = [NSFileManager defaultManager];
            NSString *documentsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
            
            NSString *filePaths = [documentsPath stringByAppendingPathComponent:fileName];
            NSError *error;
            BOOL success = [fileManager removeItemAtPath:filePaths error:&error];

NSString *fileName = [invoiceListData objectAtIndex:[indexPath row]];

NSFileManager *fileManager = [NSFileManager defaultManager];

NSString *documentsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];

NSString *filePaths = [documentsPath stringByAppendingPathComponent:fileName];

NSError *error;

BOOL success = [fileManager removeItemAtPath:filePaths error:&error];
