Multitasking is a feature that has been requested on the iPhone since it was first released. It s basically the ability to let the device run more than one program at once. For example, you may want to listen to music using the Pandora application while performing other tasks such as checking your email. In the past, Apple has had a few arguments in opposition to multitasking on the iPhone; the primary one was that it slows down the device and makes for an overall poor user experience. If you allow the user to run too many applications at once, the device will eventually run out of memory and start killing those applications. Another argument was that running applications drains battery life much more quickly. Because running an app requires processing power, the constant strain on the processor will quickly result in a drained battery. With the release of the iPhone SDK 3.0 Apple aimed to solve many users gripes about the lack of multitasking through the use of push notifications, as we discussed in chapter 16. This solved the problem for apps such as instant messengers but still didn t let users multitask on their device. Finally, in the iPhone OS 4.0, Apple has implemented the ability for programs to run in the background. This isn t true multitasking per se, but it s getting closer and addresses most of users other gripes. Applications that wish to run in the background are restricted to certain tasks, which include the following:

The actionDelete( ) method begins by setting the deleting flag to true. Setting the deleting flag alerts the tableSelectionChanged( ) method to ignore table changes while a message is being deleted. Next, the actual message deleting takes place in a few steps. First, the selectedMessage is marked as having been deleted by a call to setFlag( ) with the Flags.Flag.DELETED flag. Second, the selectedMessage s folder is closed. When folders are closed in JavaMail, any messages in the folder that have a DELETED flag are deleted. Third, the closed folder is reopened so that any other messages it contains can be accessed again. After the message is deleted from the server, it is removed from the messages table with a call to tableModel.deleteMessage( ). Finally, actionDelete( ) updates the GUI by clearing the message text area and updating the button states.

We ve summarized the four major ways that the iPhone OS supports the creation of objects in table 2.3. As witnessed by the examples, you ll use all these methods as you move through the upcoming chapters.

Table 2.3 The iPhone OS supports several methods that you can use to create objects. Different methods are supported by different classes. Method Simple Argument Code [[object alloc] init]; [[object alloc] initWithArgument:argument]; Summary Plain initialization An initialization where one or more arguments is passed to the method An initialization with an argument used for Interface Builder objects A one-step initialization process with an argument

The sendMessage( ) method, shown here, performs the actual sending of a message. In general, it works by displaying a Message dialog box and then using the data entered in the Message dialog box to create a new Message object. The new Message object is then sent with JavaMail s Transport class.

self.tableView.userInteractionEnabled = NO; [[BARTPredictionLoader sharedBARTPredictionLoader] loadPredictionXML:self];

[[object alloc] initWithCoder:decoder]; [object objecttypeWithArgument:argument];

// Send the specified message. private void sendMessage(int type, Message message) { // Display message dialog box to get message values. MessageDialog dialog; try { dialog = new MessageDialog(this, type, message); if (!dialog.display()) { // Return if dialog box was cancelled. return; } } catch (Exception e) { showError("Unable to send message.", false); return; }

Because of power considerations, the iPhone OS doesn t support garbage collection. That means every object that s created must eventually have its memory released by hand at least, if you don t want to introduce a memory leak into your program. The fundamental rule of memory management in the iPhone OS is this: if you allocate memory for an object, you must release it. This is done via the release message (which is once again inherited from NSObject):

try { // Create a new message with values from dialog box. Message newMessage = new MimeMessage(session); newMessage.setFrom(new InternetAddress(dialog.getFrom())); newMessage.setRecipient(Message.RecipientType.TO, new InternetAddress(dialog.getTo())); newMessage.setSubject(dialog.getSubject()); newMessage.setSentDate(new Date()); newMessage.setText(dialog.getContent()); // Send new message. Transport.send(newMessage); } catch (Exception e) { showError("Unable to send message.", false); } }

[object release];

8. Remember when we created a protocol for the prediction loader We need to attach this protocol to RootViewController to tell BARTPredictionLoader that RootViewController wants to be notified when the data finishes loading. In RootViewController.h, you can add the protocol to the end of the interface declaration:
