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:
#import <Foundation/Foundation.h> #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); NSString *fileText2= [[[NSString alloc] initWithBytes:[data2 bytes] length:bytesRead2 encoding:NSUTF8StringEncoding] autorelease]; NSLog(@"%@",fileText2); } [unzipFile release]; } @catch (ZipException *ze) { NSLog(@"ZipException caught: %d - %@", ze.error, [ze reason]); } @catch (id e) { NSLog(@"Exception caught: %@ - %@", [[e class] description], [e description]); } [pool drain]; return 0; } 声明:ITeye文章版权属于作者,受法律保护。没有作者书面许可不得转载。
