IOS: copy a file in documents folder

Question

In my project I have two file .txt (in Resources folder), how can I copy them inside documents folder?

Answer 1

NSFileManager *fileManager = [NSFileManager defaultManager];
NSError *error;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [[paths objectAtIndex:0]stringByAppendingString:@"csvfile"];

NSString *txtPath = [documentsDirectory stringByAppendingPathComponent:@"sample.csv"];

if ([fileManager fileExistsAtPath:txtPath] == NO) {
    NSString *resourcePath = [[NSBundle mainBundle] pathForResource:@"sample" ofType:@".csv"];
    [fileManager copyItemAtPath:resourcePath toPath:txtPath error:&error];
