  • UITableViewCell height with 0 rows

    - by Typeoneerror
    I've got a moderately uncustomized UITableView in my application that presents an array of up to 6 peers for a networking game. When no peers are found the numberOfRowsInSection is 0, so when it loads up, there's no rows in the table: - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return 0; } Trouble is, the height of each cell is not adjusted to match heightForRowAtIndexPath unless the numberOfRowsInSection is 0. I hard-coded in "1" for this and the height is adjusted. - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { return kTableRowHeight; } Can anyone tell me why this is? Will once the data that is being presented is longer than "0" length, will the height of the table cells jump to the correct height? I'd like them to be the correct height even if the row length is 0.

  • Changing pointer of self

    - by rob5408
    I have an object that I alloc/init like normal just to get a instance. Later in my application I want to load state from disk for that object. I figure I could unarchive my class (which conforms to NSCoding) and just swap where my instance points to. To this end I use this code... NSString* pathForDataFile = [self pathForDataFile]; if([[NSFileManager defaultManager] fileExistsAtPath:pathForDataFile] == YES) { NSLog(@"Save file exists"); NSData *data = [[NSMutableData alloc] initWithContentsOfFile:pathForDataFile]; NSKeyedUnarchiver *unarchiver = [[NSKeyedUnarchiver alloc] initForReadingWithData:data]; [data release]; Person *tempPerson = [unarchiver decodeObjectForKey:@"Person"]; [unarchiver finishDecoding]; [unarchiver release]; if (tempPerson) { [self release]; self = [tempPerson retain]; } } Now when I sprinkled some NSLogs throughout my application I noticed self.person: <Person: 0x3d01a10> (After I create the object with alloc/init) self: <Person: 0x3d01a10> (At the start of this method) tempPerson: <Person: 0x3b1b880> (When I create the tempPerson) self: <Person: 0x3b1b880> (after i point self to the location of the tempPerson) self.person: <Person: 0x3d01a10> (After the method back in the main program) What am I missing?

  • How do I reset the state of a view inside a tabbar?

    - by ABeanSits
    Hello CocoaTouch-Experts! This is a fairly straightforward question though my Googling session gave me nothing. How do I reset the state of a view hierarchy located in a tabbar programmatically? The behavior I want to replicate is when the user tapps on a tab twice. This causes the view located under that tab to return to it's initial state. The tab is "owned" by a UINavigationController and when the user reaches a certain point in the view hierarchy there is a button which I want to connect this behavior to. All my attempts have failed except calling on a method in AppDelegate which kills the view and adds it back to the UITabBarController again. But this does not feel like the right way to go. Thanks in advance. Best regards //Abeansits

  • UIImage Object surprisingly returning null but not NSData

    - by riyaz
    i have created a sqlite db. and i have insert a few datas in my db.. UIImage * imagee=[UIImage imageNamed:@"image.png"]; NSData *mydata=[NSData dataWithData:UIImagePNGRepresentation(imagee)]; const char *dbpath = [databasePath UTF8String]; NSString *insertSQL=[NSString stringWithFormat:@"insert into CONTACTS values(\"%@\",\"%@\")",@"Mathan",mydata]; NSLog(@"mydata %@",mydata); sqlite3_stmt *addStatement; const char *insert_stmt=[insertSQL UTF8String]; if (sqlite3_open(dbpath,&contactDB)==SQLITE_OK) { sqlite3_prepare_v2(contactDB,insert_stmt,-1,&addStatement,NULL); if (sqlite3_step(addStatement)==SQLITE_DONE) { sqlite3_bind_blob(addStatement,1, [mydata bytes], [mydata length], SQLITE_TRANSIENT); NSLog(@"Data saved"); } else{ NSLog(@"Some Error occured"); } sqlite3_close(contactDB); } else{ NSLog(@"Failure"); } have written some codes to retrive the data sqlite3_stmt *statement; if (sqlite3_open([databasePath UTF8String], &contactDB) == SQLITE_OK) { NSString *sql = [NSString stringWithFormat:@"SELECT * FROM contacts"]; if (sqlite3_prepare_v2( contactDB, [sql UTF8String], -1, &statement, nil) == SQLITE_OK) { while (sqlite3_step(statement) == SQLITE_ROW) { char *field1 = (char *) sqlite3_column_text(statement, 0); NSString *field1Str = [[NSString alloc] initWithUTF8String: field1]; NSLog(@"UserName %@",field1Str); NSData *data = [[NSData alloc] initWithBytes:sqlite3_column_blob(statement, 1) length:sqlite3_column_bytes(statement, 1)]; UIImage *newImage = [[UIImage alloc]initWithData:data]; NSLog(@"Image OBJ %@",newImage); NSLog(@"Image Data %@",data); } sqlite3_close(contactDB); } } sqlite3_finalize(statement); the problem is in log, inserted NSData object and retrieved NSData Objects are different (printing in log gives different stream) moreover Image OBJ is printed null in log.. Have seen similar questions in stackoverflow. But nothing seems to help. Please give some suggestions to overcome this issue.

  • Keyboard not dismissed

    - by sgosha
    I am developing a messaging application that have SMS.app-like UI. Conversation screen has text input field at the bottom which is moved up with keyboard. Tapping on conversation area dismisses keyboard by calling resignFirstResponder method on UITextView that we use. This usually works fine, but users report a weird bug which I can't reproduce and fix. People say that sometimes onscreen keyboard doesn't go away when they tap on conversation area, though text input field loses input focus. Once the view enters that abnormal state users are able to type with keyboard, but text that is being entered is not visible anywhere. This bug happens in one of conversation views and since then no one text input field in other views doesn't work as expected. The only way to stop this weird behavior is killing application from multitasking bar. Even more weird thing is that keyboard stays visible while navigating between view controllers in UINavigationController. I noticed two things: - if tap on ' Anyone else experiencing same problems. Any ideas on what may cause this bug?

    - by Nicolaj Zefting
    First off, I'm a complete beginner. This might be a stupid question, but here it goes: I'm currently working on an App than contains Latin texts that the users can view and read. I'm using Xcode 4 with the storybord function. Theway the app is built: user selects author - then the book - then app shows the text. I am kind of confused because i need to have various text files, depending on the users choice.

  • Clear button at uisearchbar not working at all

    - by kevin.ng
    I created a search bar programmatically and added to my view using the codes below: - (void)viewDidLoad { searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(xPositionForSearchBar, yPositionForSearchBar, widthForSearchBar, heightForSearchBar)]; UIView *bg = [[searchBar subviews] objectAtIndex:0]; searchBar.delegate = self; searchBar.placeholder = @"Search record"; for(UIView *view in searchBar.subviews){ if([view isKindOfClass:[UITextField class]]){ UITextField *tf = (UITextField *)view; tf.delegate = self; break; } } [bg removeFromSuperview]; [self.view addSubview: searchBar]; } The code is implemented with UISearchBarDelegate and UITextFieldDelegate. I have tried using - (void)searchBarCancelButtonClicked:(UISearchBar *)aSearchBar { NSLog(@"cancel clicked"); searchBar.text = @""; [aSearchBar resignFirstResponder]; } - (BOOL)textFieldShouldClear:(UITextField *)textField { NSLog(@"clear"); [self performSelector:@selector(searchBarCancelButtonClicked:) withObject:searchBar afterDelay: 0.1]; return YES; } and yet, the text inside the searchBar is not cleared at all when i click on the "clear button" - a circle with a "X" inside. The clear button works when I implemented it in IB. Wonder why? Kindly advice, many thanks.

  • Core Data strategy using in memory cache, or no core data at all?

    - by randombits
    I have a user interface where the user can check off a bunch of items from a tableview, almost like a todo list. The items are populated from a Core Data stack. I need to be able to take all of the items they're clicking through and put them into a "temporary" shopping cart. Once they're in the shopping cart, users can go through the list and remove the items, or just submit them to a server. The thing is, the selected items are temporary just like an internet based shopping cart. It's nothing something that gets persisted once the application closes. Once the view is no longer in display, I can assume that the shopping cart is safe to discard. What's the best way to approach this? Since the user is essentially clicking on instances that map back to a Core Data entity .. should I setup a different persistence store such as in memory and add that store to my managed object context?
