我需要压缩我的日志文件并通过电子邮件发送。我正在使用Objective-zip压缩我的文件。这是我的代码
-(void)mailLogFile {
if ([MFMailComposeViewController canSendMail]) {
NSDictionary *user = [[DBHelper getSharedInstance] getCurrentUser];
NSString *propertyQuery = [NSString stringWithFormat:@"SELECT RecentActivityId,PropertyPIC,PropertyId,Message,IsSynced,ActivityTime,ErrorCode,ErrorMessage,ErrorData,EntityId,TableNames From RecentActivity ORDER BY ActivityTime desc"];
NSArray *resultArry = [[DBHelper getSharedInstance] getRecordsBySQL:propertyQuery];
NSLog(@"This is the eNVDS in Recent Activity:%@" ,resultArry);
[[DBHelper getSharedInstance] AddLogFile:[NSString stringWithFormat:@"This is the eNVDS in Recent Activity:%@" ,resultArry]];
NSPredicate *notsynced = [NSPredicate predicateWithFormat:@"IsSynced == 0 || IsSynced == %@",@"0"];
NSArray *notsyncedenvds = [resultArry filteredArrayUsingPredicate:notsynced];
NSLog(@"This is the eNVDS in Recent Activity which is not synced:%@" ,notsyncedenvds);
[[DBHelper getSharedInstance] AddLogFile:[NSString stringWithFormat:@"This is the eNVDS in Recent Activity which is not synced:%@" ,notsyncedenvds]];
NSString *documentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *WritableDBPath= [documentsDirectory stringByAppendingPathComponent:@"Logfile.txt"];
NSString *path = [documentsDirectory stringByAppendingPathComponent:@"test.zip"];
NSData *zipdata = [NSData dataWithContentsOfFile:path];
NSData *data = [NSData dataWithContentsOfFile:WritableDBPath];
//OZZipFile *readFile = [[OZZipFile alloc] initWithFileName:path mode:OZZipFileModeCreate];
OZZipFile *zipFile32= [[OZZipFile alloc] initWithFileName:path mode:OZZipFileModeCreate];
OZZipWriteStream *stream= [zipFile32 writeFileInZipWithName:@"Logfile.txt" compressionLevel:OZZipCompressionLevelBest];
[stream writeData:data];
[stream finishedWriting];
NSString *emailTitle = [NSString stringWithFormat:@"Log file of %@",[NSDate date]];
NSMutableString *messageBody = [NSMutableString stringWithFormat:@"Login with %@",user[@"Username"]];
if(![user[@"PropertyName"] isKindOfClass:[NSNull class]])[messageBody appendFormat:@"\n%@",user[@"PropertyName"]];
[messageBody appendFormat:@"\nApp version : %@",APP_VERSION];
[messageBody appendFormat:@"\nPlease describe your problem scenario here."];
[messageBody appendFormat:@"\n\n\nThanks"];
NSArray *toRecipents = [NSArray arrayWithObject:@"support@aglive.com"];
MFMailComposeViewController *mc = [[MFMailComposeViewController alloc] init];
mc.mailComposeDelegate = self;
[mc setSubject:emailTitle];
[mc setMessageBody:messageBody isHTML:NO];
[mc setToRecipients:toRecipents];
[mc addAttachmentData:zipdata mimeType:@"application/zip" fileName:@"test.zip"];
[self presentViewController:mc animated:YES completion:nil];
[zipFile32 close];
}else{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Aglive Pro" message:@"You have not configured your mail account. Please configure your mail account from the device settings." delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
[alert show];
}
}
现在我可以通过电子邮件发送一个 zip 文件，但是当我解压缩并在我的手机或 mac 中打开文件时，我收到警告说无法打开文档“Logfile 4.txt”。该文件的格式不正确。我不知道我哪里错了。
