Hi,
See new sample code “MessageComposer” which includes both Mail and Messages features.
This application shows how to target older OS versions while building with newly released APIs. It also illustrates how to use the MessageUI framework to edit and send email messages from within your application.
Tap the “Compose Mail” button to display an email composition interface if your device is running iPhone OS 3.0 or launch the Mail application, otherwise.
Step 1:
Add MessageUI.framework to your Application.Add this Header file to the .h file and Provide delegate of it as shown below.
#import <MessageUI/MessageUI.h>
#import <MessageUI/MFMailComposeViewController.h>
@interface MailComposerViewController : UIViewController <MFMailComposeViewControllerDelegate>
{
IBOutlet UILabel *message;
}
@property (nonatomic, retain) IBOutlet UILabel *message;
-(IBAction)showPicker:(id)sender;
-(void)displayComposerSheet;
-(void)launchMailAppOnDevice;
Step 2:Now write the code for mail.
-(IBAction)showPicker:(id)sender
{
// This sample can run on devices running iPhone OS 2.0 or later
// The MFMailComposeViewController class is only available in iPhone OS 3.0 or later.
// So, we must verify the existence of the above class and provide a workaround for devices running
// earlier versions of the iPhone OS.
// We display an email composition interface if MFMailComposeViewController exists and the device can send emails.
// We launch the Mail application on the device, otherwise.
Class mailClass = (NSClassFromString(@”MFMailComposeViewController”));
if (mailClass != nil)
{
// We must always check whether the current device is configured for sending emails
if ([mailClass canSendMail])
{
[self displayComposerSheet];
}
else
{
[self launchMailAppOnDevice];
}
}
else
{
[self launchMailAppOnDevice];
}
}
