zip压缩和解压缩

Zipachieve第三方框架下载地址：

1.下载完成后解压，将文件拉入项目中，这是可能会报错；

2.添加libz.1.2.5.tbd，此时运行一下，要是仍然有错可能是ARC的问题，修改不兼容ARC（-fno-objc-arc）；

3.上代码：

下载一个zip文件：

NSURL *url=[NSURL URLWithString:@"http://192.168.1.102:8080/zip/JFTestFramework.framework.zip"];
    NSMutableURLRequest *re=[NSMutableURLRequest requestWithURL:url];
    
    [NSURLConnection sendAsynchronousRequest:re queue:[NSOperationQueue new] completionHandler:^(NSURLResponse * _Nullable response, NSData * _Nullable data, NSError * _Nullable connectionError) {
        if (data) {
            NSLog(@"%ld",data.length);
             [self performSelectorOnMainThread:@selector(saveFramework:) withObject:data waitUntilDone:YES];
        }else{
            
            NSLog(@"加载失败");
        }
       
    }];

 

 

保存下载的压缩包，解压压缩包，并删除原来的压缩包：

-(void)saveFramework:(NSData*)data{
    NSString *documentDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
    NSString *zipPath = [NSString stringWithFormat:@"%@/%@",documentDirectory,@"framework.zip"];
    NSLog(@"1---------%@",zipPath);
   // NSLog(@"%@",data);
   
    NSString *bundlePath = [NSString stringWithFormat:@"%@/%@",documentDirectory,@""];
    [data writeToFile:zipPath atomically:YES];
    
    ZipArchive *zip=[[ZipArchive alloc]init];
    if ([zip UnzipOpenFile:zipPath]) {
        NSLog(@"打开成功");
        if ([zip UnzipFileTo:bundlePath overWrite:YES]) {
            NSLog(@"解压成功");
            [[NSFileManager defaultManager]removeItemAtPath:zipPath error:nil];
            [zip UnzipCloseFile];
        }
        
    }
    ;
}

此时打开文件下载路径可以看到下载解压之后的文件：
