在 obj-c 中向 applescript 添加变量

Question

不确定在 objective-c 中是否可以在不将脚本作为文件的情况下使用运行那样。

    NSAppleScript *appleScriptGetHH = [[NSAppleScript alloc] initWithSource:@\
                              "tell application \"System Events\"\n \
                              tell process \"Grabee\"\n \
                              with timeout of 0 seconds\n \
                              get value of attribute \"AXValue\" of text area 1 of scroll area 1 of window \"Demo Window 1" \n \
                              end timeout \n \
                              end tell \n \
                              end tell"];

这很好用，但我想做的是用字符串替换 "Demo Window 1"（因为它将在程序中动态更改）

当我使用这样的东西时

NSString *windowName = @"Green Window4";

然后替换这一行：

get value of attribute \"AXValue\" of text area 1 of scroll area 1 of window \"Demo Window 1" \n \

有：

get value of attribute \"AXValue\" of text area 1 of scroll area 1 of window \"%@" \n \

和

end tell", windowName];

我收到一个错误，提示参数太多，有没有办法在不分开脚本的情况下执行此操作？

像这样构建字符串；

  NSAppleScript *appleScriptGetHH = [[NSAppleScript alloc] initWithSource:
         [[NSString alloc] initWithFormat:@\
                          "tell application \"System Events\"\n \
                          tell process \"Grabee\"\n \
                          with timeout of 0 seconds\n \
                          get value of attribute \"AXValue\" of text area 1 of scroll area 1 of window \"%@"  \n \
                          end timeout \n \
                          end tell \n \
                          end tell", windowName]
  ];

或者将字符串构建为一个单独的步骤以提高可读性。
