    - by VansFannel
    I'm developing an iOS application with latest Xcode 4.5.2.

    - by Sheehan Alam
    I am trying to append objects to my data source and then reload the table. Is this the correct way of approaching it? self.items is my datasource //Copy current items self.itemsCopy = [self.items mutableCopy];//[[NSMutableArray alloc] initWithArray:self.items copyItems:NO]; NSLog(@"Copy Size before append: %d",[itemsCopy count]); //Get new items int lastMsgID = [self getLastMessageID]; [self.coreData getMoreMessages:self.title lastID:lastMsgID]; //This will update self.items with 30 objects //Append new items [itemsCopy addObjectsFromArray:self.items]; //Empty items and copy itemsCopy [self.items removeAllObjects]; self.items = [self.itemsCopy mutableCopy]; NSLog(@"Actual Size after append: %d",[self.items count]); //Reload data [tableView reloadData];

  • iPhone: Switching Views From Outside Root Controller

    - by senfo
    I am using a UINavigationController to switch between views. What I would like is for each view to have the ability to control when it is swapped out for another view by having buttons within the view. All of the samples I've seen thus far have placed buttons on a toolbar, which is located on the root view containing the Switch View Controller rather than the views, them self. Is it possible to do what I want? I can't figure how to wire up the connection back to the UINavigationController. I'm having a difficult time wording this, so please feel free to let me know if you need additional clarification.

  • How to have Xcode find the newest version of a file

    - by Arian
    Currently I have a SQLite database, that is set statically to use database01.sqlite... but what I need is a way to have the file path find the newest version of the database file that exists. For example: If a database file of database04.sqlite is available, it should use that one instead. Below is my current code: NSString *databaseDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0]; NSString *filePath = [databaseDirectory stringByAppendingPathComponent:@"database01.sqlite"];

  • Read Call History from iPhone on iOS 5 and above

    - by Sandeep Dhama
    I am developing an application and need to read the users call history from iPhone.I have go though all the forums and google it and found that we can get the records from teh callHistory sqlite database by "private/var/root/Library/CallHistory/call_history.db". But this path is not working from iOS 5 and above. Seems like apple has changed all their database path and structure so that no one can accees it. I have also seen some of the application on iTunes who are capable of getting the users call history like:-https://itunes.apple.com/us/app/callog/id327883585?mt=8 I have also check a mac desktop utility called "WonderShare Dr.Fone" which will fetch all the data from your iPhone like call history messages, notes , etc.How this utility is fetching the call history records and other details? If their is any API or private APIs by which i can get the callHistory data path please let me know.

  • How Do I Bind a UIButton Property to Another Property?

    - by cygnl7
    UIButton eventually inherits from NSObject, and NSObject implements NSKeyValueBindingCreation Protocol. So why can't I bind a UIButton's property to another class' property? [myUIButton bind:@"enabled" toObject:myOtherObject withKeyPath:@"otherObjectBOOLProperty" options:nil]; This results in the warning 'UIButton' may not respond to '-bind:toObject:withKeyPath:options:' What I'm trying to do is bind the enabled state of my UIButton to myOtherObject.otherObjectBOOLProperty.

  • Pass a class as a parameter?

    - by JuBu1324
    I have been lead to believe that it is possible to pass a class as a method parameter, but I'm having trouble implementing the concept. Right now I have something like: - (id)navControllerFromView:(Class *)viewControllerClass title:(NSString *)title imageName:(NSString *)imageName { viewControllerClass *viewController = [[viewControllerClass alloc] init]; UINavigationController *thisNavController = [[UINavigationController alloc] initWithRootViewController: viewController]; thisNavController.tabBarItem = [[UITabBarItem alloc] initWithTitle: title image: [UIImage imageNamed: imageName] tag: 3]; return thisNavController; } and I call it like this: rootNavController = [ self navControllerFromView:RootViewController title:@"Contact" imageName:@"my_info.png" ]; What's wrong with this picture?

  • Generating an NSDictionary from an SQL statement.

    - by Ed Wist
    I am trying to generate an NSDictonary that can be used to populate a listview with data I retrieved from an SQL statement. when I go to create an array and add them it adds the arrays for ALL my keys and not just for the current key. I've tried a removeAllObjects on the array but for some reason that destroys ALL my data that I already put in the dictionary. //open the database if(sqlite3_open([dbPath UTF8String], &database) == SQLITE_OK) { const char *sql = "select alphaID, word from words order by word"; sqlite3_stmt *selectStatement; //prepare the select statement int returnValue = sqlite3_prepare_v2(database, sql, -1, &selectStatement, NULL); if(returnValue == SQLITE_OK) { NSMutableArray *NameArray = [[NSMutableArray alloc] init]; NSString *alphaTemp = [[NSString alloc] init]; //loop all the rows returned by the query. while(sqlite3_step(selectStatement) == SQLITE_ROW) { NSString *currentAlpha = [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectStatement, 1)]; NSString *definitionName = [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectStatement, 2)]; if (alphaTemp == nil){ alphaTemp = currentAlpha; } if ([alphaTemp isEqualToString:(NSString *)currentAlpha]) { [NameArray addObject:definitionName]; } else if (alphaTemp != (NSString *)currentAlpha) { [self.words setObject:NameArray forKey:currentAlpha]; [NameArray removeAllObjects]; [NameArray addObject:definitionName]; } } } The Statement above adds all the "keys" but then removes all the array elements for all keys. if I take out the removeAllKeys it adds ALL the array elements for ALL keys. I don't want this I want it to add the array elements FOR the specific key then move on to the next key. in the end I want a NSDictonary with A (array) Alpha (string) Apple (string) B (array) Beta (string) Ball (string) C (array) Code (string) ...

  • Does NSClassFromString affect performance?

    - by Tomen
    I want to create a controller that depends on the class of a given instance of a model -(BaseController *)getControllerForModel:(Model *)model { BaseController *controller = nil; Class controllerClass = [BaseController class]; //the default value //find the right controller if ([model isMemberOfClass:[ModelClass1 class]]) controllerClass = [ConcreteController1 class]; else if ([model isMemberOfClass:[ModelClass2 class]]) controllerClass = [ConcreteController2 class]; else if ([model isMemberOfClass:[ModelClass3 class]]) controllerClass = [ConcreteController3 class]; ... else if ([model isMemberOfClass:[ModelClassX class]]) controllerClass = [ConcreteControllerX class]; else Trace(TRACELEVEL_WARNING, @"Unrecognized model type: %@", NSStringFromClass([model class])); //Now instantiate it with the model controller = [[[controllerClass alloc] initWithModel:model] autorelease]; return slotController; } I want to find a more flexible solution to this and thought of having a dictionary, which maps Model-Classes to Controller-Classes and then NSClassFromString could give me the right instance. My question is this: Is NSClassFromString using much of my applications performance if i use it several times (say, 100 times at once)? Or would it be about as fast as the above approach?

  • Organising files and classes in XCode (iPhone application)

    - by pulegium
    It's a generic question and really a newbie one too, so bear with me... I'm playing with some iPhone development, and trying to create a simple "flip type" application. Nothing sophisticated, let's say on the flip side is a short application summary, bit like 'help' and on the main screen is a simple board game, let's say tic-tac-toe or similar. Now, XCode has generated me 'Main View', 'Flipside View' and 'Application Delegate' folders, with default template files in them. Now the question is where do I create appropriate 'MVC' classes? Let's say (V)iew classes are going to be the ones that have been automatically created. So the Flipside view class is responsible for generating text/images etc on the 'help' view. 'Main View' class is what draws the items on the table and updates the counters, etc. Where should I place the 'controller' class? And also, should it only be dealing with proxying only to the model? According to this the controller method is called from the view and manipulates the method classes. Similarly, the results from model are passed back to the view class by the controller issuing the calls to appropriate view methods. Similarly, where does the model class go? or should I just create a new folder for each, controller and model class files? What I'm after is the best practices, or just a short description how people normally structure their applications. I know it's very specific and also undefined... I came from Django background, so the way stuff is organised there is slightly different. Hope this makes sense, sorry if it's all bit vague, but I have to start somewhere :) And yes I've read quite few docs on the apple developer site, but trouble is that the documents are either going into too much detail about the language/framework/etc and the examples are way too simplistic. Actually, this leads me to the final question, has anyone know any good example of relatively complete application tutorial which I could use as a reference in organising my files?...

  • Replace an Array with an Array

    - by Dane Man
    I have and NSMutableArray and I want to replace it with another, but if I try to do it like this... firstArray = secondArray; ...then it seems to erase the entire firstArray and I get this error message.. Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSCFArray objectAtIndex:]: index (0) beyond bounds (0)' ...and the bounds should be (6) not (0). Is there a correct way to replace the array? PS: I already checked the secondArray and it functions fine.

  • iPhone audio Filter Question

    - by Joe
    Okay, I am going to try to make this totally not a "plz send teh codez kthxbai" I am considering an app which takes sound (eventually an audio track) and applies an audio filter to it. So I can play sounds with AudioServicesPlaySystemSound via AudioToolbox framework just fine. What I need is a very simple example of how I might take a sound and apply (for instance) midrange boost etc. Actually the kind of alteration is irrelevant -- if I can get my head around how the alteration is done I can figure out the rest. I am just finding both docs and examples of altering audio in code to be very scarce. Thanks for any help!

  • iphone selecting a row to change view

    I have created the view Controllers and attached those to control their respective views. I can't figure out how to make the following code to go the right views though. (This is in the root view controller:) - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { RunViewController *runViewController = [[RunViewController alloc] initWithNibName:@"RunView" bundle:[NSBundle mainBundle]]; CalcViewController *calcViewController = [[CalcViewController alloc] initWithNibName:@"CalcView" bundle:[NSBundle mainBundle]]; PushViewController *pushViewController = [[PushViewController alloc] initWithNibName:@"PushView" bundle:[NSBundle mainBundle]]; SitViewController *sitViewController = [[SitViewController alloc] initWithNibName:@"SitView" bundle:[NSBundle mainBundle]]; TimerViewController *timerViewController = [[TimerViewController alloc] initWithNibName:@"TimerView" bundle:[NSBundle mainBundle]]; [self.navigationController pushViewController:runViewController animated:YES]; [runViewController release]; [self.navigationController pushViewController:pushViewController animated:YES]; [pushViewController release]; [self.navigationController pushViewController:sitViewController animated:YES]; [sitViewController release]; [self.navigationController pushViewController:timerViewController animated:YES]; [timerViewController release]; [self.navigationController pushViewController:calcViewController animated:YES]; [calcViewController release]; runViewController = nil; pushViewController = nil; sitViewController = nil; timerViewController = nil; calcViewController = nil; } Each time I select any of the rows in the table - all of the views come up. How do I arrange them to only open the view that it is supposed to?
