}
?>

我使用此代码：
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://localhost/wsh/index.php?option=Hello"]];
NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *get = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding];
it works, but one time in code. if ill do it another one time, application has terminate.
它有效，但有一次在代码中。如果再做一次，应用程序已终止。

You are using a plain NSStringliteral where an NSURLobject is expected: [...] initWithURL:@"http://localhost/wsh/index.php"[...]
您NSString在需要NSURL对象的地方使用普通文字：[...] initWithURL:@"http://localhost/wsh/index.php"[...]
Change this to initWithURL:[NSURL URLWithString:@"http://localhost/wsh/index.php"].
将此更改为initWithURL:[NSURL URLWithString:@"http://localhost/wsh/index.php"].

I wonder if also you should switch the value and key for the post values, ie change the line
我想知道您是否也应该切换帖子值的值和键，即更改行
[request setPostValue:@"option" forKey:@"myFormField1"];
to
到
[request setPostValue:@"myFormField1" forKey:@"option"];
