IOS發送電子郵件

簡介

我們可以使用IOS設備中的電子郵件應用程序發送電子郵件。

實例步驟

1、創建一個簡單的View based application

2、選擇項目文件，然後選擇目標，然後添加MessageUI.framework

3、在ViewController.xib中添加一個按鈕，創建用於發送電子郵件的操作（action）

4、更新ViewController.h,如下所示

#import <UIKit/UIKit.h>
#import <MessageUI/MessageUI.h>
@interface ViewController : UIViewController<MFMailComposeViewControllerDelegate>
{
MFMailComposeViewController *mailComposer;
}
-(IBAction)sendMail:(id)sender;
@end

5、如下所示，更新ViewController.m

#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

輸出

當運行該應用程序，會看如下的輸出結果

當點擊"send email"發送按鈕後，可以看到如下結果：
