My mac(10.9) has joined into a AD domain. In my program, I tried to recognize whether the current login user is local account or AD user. I can successfully distinguish them by using the following code.
+ (bool)isLocalUser:(NSString*)user
{
NSError *dirSearchError = nil;
ODRecord *foundUser = findUser(user, &dirSearchError);
if(foundUser !=nil)
{
return YES;
}else
{
return NO;
}
}
ODRecord *findUser(NSString *user, NSError **error)
{
NSLog(#"[MacLogonUI] findUser");
ODNode *searchNode = [ODNode nodeWithSession: [ODSession defaultSession]
type: kODNodeTypeLocalNodes
error: error];
if (searchNode == nil) {
return nil;
}
NSDictionary *nodeInfo = [searchNode nodeDetailsForKeys:nil error:error];
/* query this node for the user record we're interested in.
* We only need one result, which is why maximumResults is set to 1.
*/
ODQuery *userSearch = [ODQuery queryWithNode: searchNode
forRecordTypes: kODRecordTypeUsers
attribute: kODAttributeTypeRecordName
matchType: kODMatchEqualTo
queryValues: user
returnAttributes: kODAttributeTypeStandardOnly
maximumResults: 1
error: error];
if (userSearch == nil) {
return nil;
}
/* For this example we'll use a synchronous search. This could take a while
* so asynchronous searching is preferable.
*/
NSArray *foundRecords = [userSearch resultsAllowingPartial: NO error: error];
if (foundRecords == nil || [foundRecords count] == 0) {
return nil;
}
ODRecord *userRecord = [foundRecords objectAtIndex: 0];
return [[userRecord retain] autorelease];
}
While when the AD user create a mobile card, it is viewed as a managed user(from the System preference -> Users & Groups). The code also recognize this kind of AD user as local. How to deal with this kind of situation?
Do you guys have any idea of this problem?
I have solved this problem by myself. Hope the following code helps:

#import <OpenDirectory/OpenDirectory.h>
#import <Collaboration/Collaboration.h>

{
return NO;
}
}

{
NSLog(#"[MacLogonUI] findUser");

CSIdentityClass identityClass = kCSIdentityClassUser;
CSIdentityQueryRef query = CSIdentityQueryCreate(NULL, identityClass, defaultAuthority);
CFErrorRef err = NULL;
CSIdentityQueryExecute(query, 0, &err);
CFArrayRef results = CSIdentityQueryCopyResults(query);
int numResults = CFArrayGetCount(results);
NSMutableArray * managedUsers = [NSMutableArray array];

While when network of the mac is disconnected. The managed user can not be listed. Is there anybody has any idea of this?
I've pieced together several tutorials to create a grouped table with sections and I'm now trying to get a uisearchbar to work. the problem I'm having is how to search within the grouped sections.
I've read the similar questions this post suggested but can't
This is the code to create the grouped sections
#import "Job.h" // A model for the data
#import "Address.h" // Another model for the data
- (void)viewDidLoad
{
[super viewDidLoad];
self.theTable.delegate = self;
self.theTable.dataSource =self;
_searchBar.delegate = (id)self;
FMDBDataAccess *db = [[FMDBDataAccess alloc] init];
jobs = [[NSMutableArray alloc] init];
jobs = [db getJobs:1];
_sections = [[NSMutableDictionary alloc] init];
NSMutableArray *jobsTempArray = [db getJobsAsDictionary:1];
BOOL found;
// Loop through the books and create our keys
for (NSDictionary *book in jobsTempArray)
{
NSString *cLong = [book objectForKey:#"addrAddress"];
NSString *c = [cLong substringToIndex:1];
found = NO;
for (NSString *str in [_sections allKeys])
{
if ([str isEqualToString:c])
{
found = YES;
}
}
if (!found)
{
[_sections setValue:[[NSMutableArray alloc] init] forKey:c];
}
}
// Loop again and sort the books into their respective keys
for (NSDictionary *book in jobsTempArray)
{
[[_sections objectForKey:[[book objectForKey:#"addrAddress"] substringToIndex:1]] addObject:book];
}
// Sort each section array
for (NSString *key in [_sections allKeys])
{
[[_sections objectForKey:key] sortUsingDescriptors:[NSArray arrayWithObject:[NSSortDescriptor sortDescriptorWithKey:#"addrAddress" ascending:YES]]];
}
}
And this is the code that searches
-(void)searchBar:(UISearchBar*)searchBar textDidChange:(NSString*)text
{
if(text.length == 0)
{
_isFiltered = FALSE;
}
else
{
_isFiltered = true;
_filteredjobs = [[NSMutableArray alloc] init];
//for (Job* book in jobs)
//for (Job* book in [_sections allKeys])
//for (NSString *food in [_sections allKeys])
for (NSDictionary* book in [_sections allKeys])
{
NSString *addrStr = [book objectForKey:#"addrAddress"];
NSString *postStr = [book objectForKey:#"addrPostcode"];
//NSRange nameRange = [book.jobAddress rangeOfString:text options:NSCaseInsensitiveSearch];
NSRange nameRange = [addrStr rangeOfString:text options:NSCaseInsensitiveSearch];
//NSRange descriptionRange = [book.jobPostcode rangeOfString:text options:NSCaseInsensitiveSearch];
NSRange descriptionRange = [postStr rangeOfString:text options:NSCaseInsensitiveSearch];
if(nameRange.location != NSNotFound || descriptionRange.location != NSNotFound)
{
[_filteredjobs addObject:book];
}
}
}
[self.theTable reloadData];
}
I've got as far as realising I need to change for (Job* food in jobs) to for (NSDictionary* book in [_sections allKeys]) but I'm stuck how to search within [_sections allKeys]
Specifically this line
NSRange nameRange = [addrStr rangeOfString:text options:NSCaseInsensitiveSearch];
which crashes with
-[__NSCFString objectForKey:]: unrecognized selector sent to instance 0x692e200
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFString objectForKey:]:
unrecognized selector sent to instance 0x692e200':
Any ideas? PS Treat me as a noob, I'll need some code as well as explanation - I'm still learning obj-c
Check the Link.It shows the UISearchBar With Grouped Section Tableview.Its a simple Tutorial..Hope its useful for you
I found the answer in
UISearchBar - search a NSDictionary of Arrays of Objects and reading up on allkeys.
Basically loop through the grouped NSDictionary and extract the NSArrays, then loop through again searching...
-(void)searchBar:(UISearchBar*)searchBar textDidChange:(NSString*)text
{
if(text.length == 0)
{
_isFiltered = FALSE;
}
else
{
_isFiltered = true;
_filteredjobs = [[NSMutableArray alloc] init];
NSString *currentLetter = [[NSString alloc] init];
for (int i=0; i<[_sections count]; i++)
{
currentLetter = [[_sections allKeys] objectAtIndex:i];
NSArray *jobsForKey = [ [NSArray alloc] initWithArray:[_sections objectForKey:[[_sections allKeys] objectAtIndex:i]] ];
for (int j=0; j<[jobsForKey count]; j++)
{
NSDictionary *book = [jobsForKey objectAtIndex:j];
NSRange titleResultsRange = [[book objectForKey:#"addrAddress"] rangeOfString:text options:NSCaseInsensitiveSearch];
if(titleResultsRange.location != NSNotFound)
{
[_filteredjobs addObject:book];
}
}
}
}
[self.theTable reloadData];
}
I've made an implementation for an JSON-RPC (a little bit modified) Server/Client in objective-c with the GCDAsyncSocket library. but the app crashes on responding to an request. without debugging for zombies i'm getting this error:
JSONRPCTestServer(1301,0x7fff7f887960) malloc: *** error for object 0x10014db10: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
the screenshot in xcode shows the error is in the completeCurrentRead method of the GCDAsyncSocket library.
when debugging for zombies it logs this:
2013-02-04 14:36:16.430 JSONRPCTestServer[1367:603] *** -[__NSArrayI release]: message sent to deallocated instance 0x1005b6fd0
and instruments shows this:
as this happens when a response to the rpc-call is of type nsarray i'd guess its this array that is causing the error. the rpc-method is:

i just don't know how to fix this. why do i keep getting an error with an nsarray but when i return a nsnumber it works? how can i fix this?
I need to send email in background, so I have to use the library named: SMTP. And the main class I used is: SKPSMTPMessage. The problem is "ccEmail", when I add more than 2 recipients, it can't send email. (that takes too long time to go to delegate methods). It works well with recipient <= 2.
smtpEmail.ccEmail = #"xyz#gmail.com, xyz1#gmail.com, xyz2#gmail.com";
Anyone knows this, please help me. Thanks you so much !
There is my changes in the parseBuffer function:
case kSKPSMTPWaitingFromReply:
{
if ([tmpLine hasPrefix:#"250 "]) {
if (!multipleRcptTo) {
NSMutableString *multipleRcptToString = [NSMutableString string];
[multipleRcptToString appendString:[self formatAddresses:toEmail]];
[multipleRcptToString appendString:[self formatAddresses:ccEmail]];
[multipleRcptToString appendString:[self formatAddresses:bccEmail]];
multipleRcptTo = [[multipleRcptToString componentsSeparatedByString:#"\r\n"] mutableCopy];
[multipleRcptTo removeLastObject];
}
if ([multipleRcptTo count] > 0) {
NSString *rcptTo = [NSString stringWithFormat:#"%#\r\n", [multipleRcptTo objectAtIndex:0]];
[multipleRcptTo removeObjectAtIndex:0];
//DEBUGLOG(#"C: %#", rcptTo);
if (CFWriteStreamWriteFully((CFWriteStreamRef)outputStream, (const uint8_t *)[rcptTo UTF8String], [rcptTo lengthOfBytesUsingEncoding:NSUTF8StringEncoding]) < 0)
{
error = [outputStream streamError];
encounteredError = YES;
}
else
{
[self startShortWatchdog];
}
}
if ([multipleRcptTo count] == 0) {
sendState = kSKPSMTPWaitingToReply;
}
}
break;
}
and add this into header:
NSMutableArray *multipleRcptTo;
EDIT : Also change below method as multipleRcptTo is used as NSMutableString which is local declaration :
- (NSString *)formatAddresses:(NSString *)addresses {
NSCharacterSet *splitSet = [NSCharacterSet characterSetWithCharactersInString:#";,"];
NSMutableString *multipleRcpt = [NSMutableString string];
if ((addresses != nil) && (![addresses isEqualToString:#""])) {
if( [addresses rangeOfString:#";"].location != NSNotFound || [addresses rangeOfString:#","].location != NSNotFound ) {
NSArray *addressParts = [addresses componentsSeparatedByCharactersInSet:splitSet];
for( NSString *address in addressParts ) {
[multipleRcpt appendString:[self formatAnAddress:address]];
}
}
else {
[multipleRcpt appendString:[self formatAnAddress:addresses]];
}
}
return(multipleRcpt);
}
SKPSMTPMessage sends to the SMTP address all at once, and must send one by one.
I'm trying to add a Search bar to my UITableView. I followed this tutorial: http://clingingtoideas.blogspot.com/2010/02/uitableview-how-to-part-2-search.html.
I'm getting this error if I type a letter in the search box: Rooster(10787,0xa05ed4e0) malloc: *** error for object 0x3b5f160: double free
*** set a breakpoint in malloc_error_break to debug.
This error occurs here:

[strI release];
}
[klasString release];
}
}
}
Can someone help me out?
Regards,

The double free error means you have released an object more than needed. Here the suspicious object is klasString.
From your code:
NSString *klasString = [[NSString alloc] init];
...
if(i != -1) {
klasString = [klassenList objectAtIndex:(i - 1)];
}
...
[klasString release];
The assignment inside the if statement
loses reference to the newly allocated NSString, introducing a memory leak
makes the later release apply to the object from klassenList. When klassenList releases its elements, a double free error will occur.
