objective-c - NSApplescript 不会接受 initWithContentsOfURL

Question

我是新手，所以请耐心等待。我的问题出在以下代码中:

AppleScriptController.h

#import <Foundation/Foundation.h>
#import <Cocoa/Cocoa.h>        
@interface AppleScriptController : NSObject    
-(void)test;
@end

AppleScriptController.m

#import "AppleScriptController.h"    
@implementation AppleScriptController

-(void)test{
    NSString *path = [[NSBundle mainBundle] pathForResource:@"beep" 
                                                 ofType:@"scpt"];    
    NSAppleScript *script2 = [[NSAppleScript alloc]
                          initWithContentsOfURL:[NSURL fileURLWithPath:path] 
                          error:nil];    
    [script2 executeAndReturnError:nil];    
}
@end

(beep.scpt 的副本位于支持文件中)

main.m

#import <Foundation/Foundation.h>
#import "AppleScriptController.h"

AppleScriptController *myScript = [[AppleScriptController alloc] init];
[myScript test];

当我运行它时，我收到以下错误消息:线程1:程序收到信号:“SIGABRT”

NSAppleScript *script2 = [[NSAppleScript alloc]
                          initWithContentsOfURL:[NSURL fileURLWithPath:path] 
                          error:nil];    Thread 1: Program received signal: "SIGABRT"

并得到以下错误代码:

当我将 m 文件更改为 initWithSource 时，程序运行正常:

NSAppleScript *script1 = [[NSAppleScript alloc] initWithSource:@"beep 10"];
[script1 executeAndReturnError:nil];

我在 OS X 10.7.5 上运行 XCode 4.2.1

请告诉我哪里出错了。我确信这是某种新手错误，但我似乎无法找到它。

非常感谢任何建议!

Answer 1

来自错误代码:

reason: '* -[NSURL initFileURLWithPath:]: nil string

所以这里:

NSString *path = [[NSBundle mainBundle] pathForResource:@"beep" 
                                             ofType:@"scpt"];    
NSAppleScript *script2 = [[NSAppleScript alloc]
                      initWithContentsOfURL:[NSURL fileURLWithPath:path] 
                      error:nil];  

路径为零。因此，该文件很可能不在 bundle 中。将其添加为项目的目标。

如何做

例如，最后一天我需要在 bundle 中添加鲨鱼的图像，具体方法如下:
