Question

在我的应用中我创建了一个csv文件，所以我创建了这个方法：

+ (void)saveFileFromArray:(NSMutableArray *)promoArray {
    NSMutableString *target = [@"Nome,Cognome,E-mail,Data di nascita,Indirizzo,Città,Cap,Telefono\n" mutableCopy];

    for (NSDictionary *dict in promoArray) {
        [target appendFormat:@"%@,%@,%@,%@,%@,%@,%@,%@\n",dict[@"name"],dict[@"surname"],dict[@"email"],dict[@"birthdate"],dict[@"address"],dict[@"city"],dict[@"zip"],dict[@"phone"]];
    }
    NSError *error = nil;

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *fileName = [documentsDirectory stringByAppendingPathComponent:@"profiles.csv"];

    NSURL *url = [NSURL URLWithString:fileName];

    BOOL success = [target writeToURL:url atomically:YES encoding:NSUTF8StringEncoding error:&error];

    if (!success) {
        NSLog(@"Errore: %@", error.localizedDescription);
    }
}

但是当我运行应用程序时，它现在保存了.plist文件，但它没有保存.csv文件。当我看到控制台时，它告诉我：Error: The operation couldn’t be completed. (Cocoa error 514.)。所以我在网上搜索了什么意思是错误514，我发现this，我在其中搜索了错误，我找到了NSFileWriteInvalidFileNameError = 514，我怎么能解决这个错误？在我的方法中，问题是什么。我希望你能帮助我解决这个问题

由MYSELF解决：

+ (void)saveFileFromArray:(NSMutableArray *)promoArray {
    NSMutableString *target = [@"Nome,Cognome,E-mail,Data di nascita,Indirizzo,Città,Cap,Telefono\n" mutableCopy];

    for (NSDictionary *dict in promoArray) {
        [target appendFormat:@"%@,%@,%@,%@,%@,%@,%@,%@\n",dict[@"name"],dict[@"surname"],dict[@"email"],dict[@"birthdate"],dict[@"address"],dict[@"city"],dict[@"zip"],dict[@"phone"]];
    }
    NSError *error = nil;

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *fileName = [documentsDirectory stringByAppendingPathComponent:@"profiles.csv"];

    BOOL success = [target writeToFile:fileName atomically:YES encoding:NSUTF8StringEncoding error:&error];

    if (!success) {
        NSLog(@"Errore: %@", error.localizedDescription);
    }
}

更改此行

BOOL success = [target writeToURL:url atomically:YES encoding:NSUTF8StringEncoding error:&error];

到

BOOL success = [target writeToFile:fileName atomically:YES encoding:NSUTF8StringEncoding error:&error];

无法在iOS中创建文件（可可错误514.）
