Question

我想将用户统计信息添加到我的应用中。我喜欢将iOS版本和iDevice模型转换为我服务器上的.csv文件。我知道如何获取iOS版本和型号名称，但不知道如何将数据写入.csv文件

获取iOS版本：[UIDevice currentDevice]. systemVersion;

获取型号名称：[UIDevice currentDevice]. model;

是否有人知道如何将iOS系统版本编写为csv文件，如下所示：

iPhone，6.1

iPad，5.1

iPod，4.3

这是我现在使用的代码，但字符串未写入.csv文件：

NSString *userinfopath = @"http://idoodler.de/userdata.csv";

    NSURL *userinfo = [NSURL URLWithString:userinfopath];


    if (![[NSFileManager defaultManager] fileExistsAtPath:userinfopath]) {
        [[NSFileManager defaultManager] createFileAtPath: userinfopath contents:nil attributes:nil];
        NSLog(@"Route creato");
    }

    NSMutableString *writeString = [NSMutableString stringWithFormat:@"%@ ,%@",[UIDevice currentDevice]. model,[UIDevice currentDevice]. systemVersion];


    NSLog(@"writeString :%@",writeString);

    NSFileHandle *handle;
    handle = [NSFileHandle fileHandleForWritingAtPath: userinfopath ];
    //say to handle where's the file fo write
    [handle truncateFileAtOffset:[handle seekToEndOfFile]];
    //position handle cursor to the end of file
    [handle writeData:[writeString dataUsingEncoding:NSUTF8StringEncoding]];

使用此代码

- (IBAction)saveAsFileAction:(id)sender {

    if (![[NSFileManager defaultManager] fileExistsAtPath:[self dataFilePath]]) {
        [[NSFileManager defaultManager] createFileAtPath: [self dataFilePath] contents:nil attributes:nil];
        NSLog(@"Route creato");
    }

    NSMutableString *writeString = [NSMutableString stringWithFormat:@"%@ ,%@",[UIDevice currentDevice]. model,[UIDevice currentDevice]. systemVersion]; 


    NSLog(@"writeString :%@",writeString);

    NSFileHandle *handle;
    handle = [NSFileHandle fileHandleForWritingAtPath: [self dataFilePath] ];
    //say to handle where's the file fo write
    [handle truncateFileAtOffset:[handle seekToEndOfFile]];
    //position handle cursor to the end of file
    [handle writeData:[writeString dataUsingEncoding:NSUTF8StringEncoding]];

}
