iOS - 發(fā)送電子郵箱(Email)

簡(jiǎn)介

我們可以使用電子郵件應(yīng)用程序 iOS 設(shè)備發(fā)送電子郵件(Email)。

涉及的步驟

1. 創(chuàng)建一個(gè)簡(jiǎn)單的 View based application.

2. 選擇項(xiàng)目文件，然后選擇目標(biāo)，添加 MessageUI.framework.

3. 在 ViewController.xib 添加一個(gè)按鍵并創(chuàng)建一個(gè)用于發(fā)送電子郵件的動(dòng)作。

4. 更新 ViewController.h 如下

#import <UIKit/UIKit.h>
#import <MessageUI/MessageUI.h>

@interface ViewController : UIViewController<MFMailComposeViewControllerDelegate>
{
    MFMailComposeViewController *mailComposer;
}

-(IBAction)sendMail:(id)sender;

@end

4. 更新 ViewController.m 如下

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];   
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

-(void)sendMail:(id)sender{
    mailComposer = [[MFMailComposeViewController alloc]init];
    mailComposer.mailComposeDelegate = self;
    [mailComposer setSubject:@"Test mail"];
    [mailComposer setMessageBody:@"Testing message 
    for the test mail" isHTML:NO];
    [self presentModalViewController:mailComposer animated:YES];
}

#pragma mark - mail compose delegate
-(void)mailComposeController:(MFMailComposeViewController *)controller 
 didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error{
   if (result) {
        NSLog(@"Result : %d",result);
    }
    if (error) {
        NSLog(@"Error : %@",error);
    }
    [self dismissModalViewControllerAnimated:YES];

}

@end
