我在我的 Cocoa 项目中使用以下代码来调用我制作的脚本。该脚本与项目位于同一文件夹中,甚至显示在 Xcode 中的“资源”文件夹下。找到了正确的路径,但它仍然说该路径不可访问。请帮忙。
NSBundle *mainBundle=[NSBundle mainBundle];
NSString *path=[mainBundle pathForResource:@"script" ofType:@"sh"];
NSTask *task = [[NSTask alloc] init];
[task setLaunchPath: path];
NSLog (path);
NSPipe *pipe = [NSPipe pipe];
[task setStandardOutput: pipe];
[task setStandardError: pipe];
NSFileHandle *file = [pipe fileHandleForReading];
[task launch];
[task waitUntilExit];
NSData *data = [ddFile readDataToEndOfFile];
NSString *output = [[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding];
NSNumberFormatter *f = [[NSNumberFormatter alloc] init];
[f setNumberStyle:NSNumberFormatterDecimalStyle];
HDSpeed = [f output];
[f release];
[task release];
我在调试器中得到的输出是:
