how to zip and email a file using objective c? - objective-c

Question

I need to zip my log file and email it. I'm using Objective-zip for zipping my file. And this is my code
-(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];
}
}
right now I'm able to send a zip file in email but when I do unzip and open the file in my mobile or mac I get alert saying that The document “Logfile 4.txt” could not be opened. The file isn’t in the correct format. I don't know where I'm going wrong.

This code worked for me
-(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:#"Logfile.zip"];
NSData *zipdata = [NSData dataWithContentsOfFile:path];
NSData *data = [NSData dataWithContentsOfFile:WritableDBPath];
OZZipFile *zipFile32= [[OZZipFile alloc] initWithFileName:path mode:OZZipFileModeCreate];
//NSData *zipdata2 = [NSData dataWithContentsOfFile:zipFile32];
OZZipWriteStream *stream= [zipFile32 writeFileInZipWithName:#"LogFile.txt" compressionLevel:OZZipCompressionLevelBest];
[stream writeData:data];
[stream finishedWriting];
[zipFile32 close];
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];
//
if(zipdata== 0 && zipdata==nil)
{
[self mailLogFile];
}
else
{
[mc addAttachmentData:zipdata mimeType:#"application/zip" fileName:#"Logfile.zip"];
[self presentViewController:mc animated:YES completion:nil];
}
