使用Objective-zip的库读取zip文件,地址:http://code.google.com/p/objective-zip/

可以在iphone上进行运行.

简单的测试代码:

Cpp代码

#import

#import "Objective-Zip/ZipFile.h"

#import "Objective-Zip/ZipException.h"

#import "Objective-Zip/FileInZipInfo.h"

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

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

// insert code here...

NSLog(@"Hello, World!");

//初始化目录

NSString *documentsDir= [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];

NSString *filePath= [documentsDir stringByAppendingPathComponent:@"5.zip"];

//此文件在zip包中,我们就读取此文件

NSString *f = @"META-INF/container.xml";

@try {

ZipFile *unzipFile= [[ZipFile alloc] initWithFileName:filePath mode:ZipFileModeUnzip];

NSArray *infos= [unzipFile listFileInZipInfos];

FileInZipInfo *currentInfo=Nil;

//列出所有在zip中的文件信息

for (FileInZipInfo *info in infos) {

//@"- %@ %@ %d (%d)"

NSString *fileInfo= [NSString stringWithFormat:@"%@", info.name, info.date, info.size, info.level];

if([fileInfo isEqualToString:f]){

NSLog(@"%@",fileInfo);

}

NSLog(@"%@",fileInfo);

}

//直接定位到要读取的文件

if([unzipFile locateFileInZip:f]){

//取得读取文件流

ZipReadStream *read2= [unzipFile readCurrentFileInZip];

currentInfo = [unzipFile getCurrentFileInZipInfo];

//开始进行读取

NSMutableData *data2= [[[NSMutableData alloc] initWithLength:currentInfo.length] autorelease];

int bytesRead2= [read2 readDataWithBuffer:data2];

NSLog(@"SIZE IS:%d,Read size is :%d",currentInfo.length,bytesRead2);
