解压缩,没有提示

Question

我正在创建一个应用程序来解压缩zip文件而不提示.我在Vmaware中使用MAC OS 10.5映像.

我是可可编程的新手.我搜索了几个关于此的代码,但它没有工作..我没有收到任何错误或警告消息..请告诉我它的正确解决方案..Zip文件没有解压缩,我的应用程序在一段时间后关闭.我想在不提示和使用任何第三方存档应用程序的情况下解压缩文件.

我想在ZIP文件的同一位置解压缩我的文件.

这是我的代码:

/* Assumes sourcePath and targetPath are both
   valid, standardized paths. */

// Create the zip task
NSTask * backupTask = [[NSTask alloc] init];
[backupTask setLaunchPath:@"/usr/bin/ditto"];
[backupTask setArguments:
    [NSArray arrayWithObjects:@"-c", @"-k", @"-X", @"--rsrc", 
    @"~/Desktop/demos.zip", @"~/Desktop", nil]];

// Launch it and wait for execution
[backupTask launch];
[backupTask waitUntilExit];

// Handle the task's termination status
if ([backupTask terminationStatus] != 0)
    NSLog(@"Sorry, didn't work.");

// You *did* remember to wash behind your ears ...
// ... right?
[backupTask release];

- 谢谢 - 问候!

我拿了你的代码并改变了一些选项.您已指定所有内容的完整路径.

#import <Foundation/Foundation.h>

int main(int argc, char *argv[]) {

NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];

// Need to use the full path to everything
// In this example, I am using my Downloads directory
NSString *destination = [@"~/Downloads" stringByExpandingTildeInPath];
NSString *zipFile = [@"~/Downloads/demos.zip" stringByExpandingTildeInPath];


NSTask *unzip = [[NSTask alloc] init];
[unzip setLaunchPath:@"/usr/bin/unzip"];
[unzip setArguments:[NSArray arrayWithObjects:@"-u", @"-d", 
                     destination, zipFile, nil]];

NSPipe *aPipe = [[NSPipe alloc] init];
[unzip setStandardOutput:aPipe];

[unzip launch];
[unzip waitUntilExit];
[unzip release];


// You can get rid of all the NSLog once you have finish testing
NSData *outputData = [[aPipe fileHandleForReading] readDataToEndOfFile];
NSString *outputString = [[NSString alloc] initWithData:outputData encoding:NSUTF8StringEncoding];

NSLog(@"Zip File: %@", zipFile);
NSLog(@"Destination: %@", destination);
NSLog(@"Pipe: %@", outputString);
NSLog(@"------------- Finish -----------");
[outputString release];


[pool release];
return 0;
}
