NSURL 对象中的多个参数

发布于 2024-07-22 06:57:02 字数 582 浏览 7 评论 0原文

我想将多个参数从 iphone sdk 传递到与 mySQL 数据库接口的服务器端 php。

我找到了一些关于如何执行此操作的答案，但我很难弄清楚如何包含多个参数。

我现在所拥有的是

- (IBAction)sendButtonPressed:(id)sender
{
    NSString *urlstr = [[NSString alloc] initWithFormat:@"http://server.com/file.php?date=%d", theDate];
    NSURL *url = [[NSURL alloc] initWithString:urlstr];

    [urlstr release];
    [url release];
}

适用于 1 个参数的，但我正在寻找的是类似

http://server.com/file.php?date=value&time=value&category=value&tags=value&entry=value

我将如何做到这一点？

I would like to pass multiple parameters from the iphone sdk to a server-side php which interfaces with a mySQL database.

i found some answers on how to do this, but i'm having a hard time figuring out how to include several parameters.

what i have right now is

- (IBAction)sendButtonPressed:(id)sender
{
    NSString *urlstr = [[NSString alloc] initWithFormat:@"http://server.com/file.php?date=%d", theDate];
    NSURL *url = [[NSURL alloc] initWithString:urlstr];

    [urlstr release];
    [url release];
}

which would work for 1 parameter, but what i'm looking for would be something like

http://server.com/file.php?date=value&time=value&category=value&tags=value&entry=value

how would i going about doing this?

- initWithFormat 方法采用多个格式字符串参数。

因此，您可以执行以下操作：

  NSString *urlstr = [[NSString alloc] initWithFormat:@"http://server.com/file.php?date=%d&second=%d&third=%d", theDate, 2, thirdIVar];

- initWithFormat 的工作方式几乎与 printf() 及其变体相同。

以下是一些 printf() 示例 http://stahlforce。 com/dev/index.php?tool=csc02

编辑：变量 nameField、tagsField、dreamEntry 在哪里定义和设置？

除非它们是 NSString 并在 @interface 中定义，否则您不能以这种方式使用它们。

我建议对一些值进行硬编码以进行测试：

    NSString *urlstr = [[NSString alloc] initWithFormat:@"http://server.com/file.php?date=%@&time=%@&name=%@&category=%d&tags=%@&entry=%@", nil, nil, @"Name", nil, @"Tags", @"Dream"];

The - initWithFormat method takes multiple arguments for the format string.

So you can do things like this:

  NSString *urlstr = [[NSString alloc] initWithFormat:@"http://server.com/file.php?date=%d&second=%d&third=%d", theDate, 2, thirdIVar];

- initWithFormat works almost identically to printf() and it variants.

Here is some printf() examples http://stahlforce.com/dev/index.php?tool=csc02

Edit: Where are the variables nameField, tagsField, dreamEntry defined and set?

Unless they are NSStrings and defined in the @interface you can not uses them in this way.

I suggest hard coding some values for testing:

    NSString *urlstr = [[NSString alloc] initWithFormat:@"http://server.com/file.php?date=%@&time=%@&name=%@&category=%d&tags=%@&entry=%@", nil, nil, @"Name", nil, @"Tags", @"Dream"];
