从 cocoa 运行 applescript 应用程序停止工作

Question

直到最近，这段代码一直运行良好。 我没有改变任何东西，也没有升级我的系统，我完全糊涂了。

我已经使用它 6 年了，现在它死在我身上。

从 cocoa 应用程序中运行 applescript 是否有更简单或更好的方法？ 在这一点上，我很乐意花钱解决这个问题！

实用程序.h

#import <Foundation/Foundation.h>

@interface Utils : NSObject
// Runs an applescript with a given map of variables (name/value)
+ (NSArray *)runApplescript:(NSString *)source withVariables:(NSDictionary *)variables;
// Runs an applescript from a file pathwith a given map of variables
// (name/value)
+ (NSArray *)runApplescriptFromFile:(NSString *)scriptName withVariables:(NSDictionary *)variables;
+ (NSArray *)arrayFromDescriptor:(NSAppleEventDescriptor *)descriptor;
// String is empty or only has white characters (space, tab...)
+ (BOOL)stringIsEmptyOrWhite:(NSString *)string;
@end

Utils.M #import "Utils.h"

@implementation Utils

+ (NSArray *)arrayFromDescriptor:(NSAppleEventDescriptor *)descriptor {
    // Enumerate the apple descriptors (lists) returned by the applescript and
    // make them into arrays
    NSMutableArray *returnArray = [NSMutableArray array];
    NSInteger counter, count = [descriptor numberOfItems];

    for (counter = 1; counter <= count; counter++) {
        NSAppleEventDescriptor *desc = [descriptor descriptorAtIndex:counter];
        if (nil != [desc descriptorAtIndex:1]) {
            [returnArray addObject:[Utils arrayFromDescriptor:desc]];
        } else {
            NSString *stringValue = [[descriptor descriptorAtIndex:counter] stringValue];
            if (nil != stringValue) {
                [returnArray addObject:stringValue];
            } else {
                [returnArray addObject:@""];
            }
        }
    }
    return returnArray;

                                                                              variableName, variableValue, nil]];
        } else if ([variableValue isKindOfClass:[NSArray class]]) {

    NSLog(@"Final script: %@", finalScript);

更容易，是的，尽管这是否是您的实际问题是另一个问题。

我假设您已经处理了其他详细信息，包括沙盒和强化设置以及 plist 条目。 （最近的 Xcode 升级也有在自动升级项目文件时打破它的习惯，通过为您打开硬化，这样 Apple 事件就无法退出。）
