Question

我想发送带附件的邮件。在我的应用程序中，我为mail函数创建了一个单独的类，在rootViewController中我有按钮通过电子邮件发送。当我点击它我的邮件功能必须被调用，但它没有。

  MFMailViewController *controller = [[MFMailViewController alloc] initWithNibName:"MFMailViewController" bundle:nil];                


[[self navigationController] pushViewController:viewController animated:YES];
[viewController release];

之后我知道我不能使用这样的邮件功能。任何人都可以帮我找到这个

Answer 1

在MFMailViewController类中创建一个实例方法，其中包含一些参数，如字典或NSArray

当您点击Email it按钮时，您正在创建MFMailViewController的对象，然后使用控制器对象调用实例方法并将参数或信息传递给。然后推动它的导航视图。

#import <Foundation/Foundation.h>

@interface MFMailViewController：NSObject

{}

- （无效）sendEmail：（的NSMutableDictionary *）withData;

@end
#import "MFMailViewController.h"

@implementation MFMailViewController

-(void)sendEmail:(NSMutableDictionary*)withData;
{
    //definition goes here.................

}
@end

MFMailViewController *controller = [[MFMailViewController alloc] initWithNibName:"MFMailViewController" bundle:nil];                

[controller sendEmail:withData];
[[self navigationController] pushViewController:viewController animated:YES];
[viewController release];

它不是MFMailViewController，它是MFMailComposeViewController。请仔细阅读Apple reference以获取更多详细信息。

以下是示例代码

if([MFMailComposeViewController canSendMail]) {
MFMailComposeViewController *mailController = [[MFMailComposeViewController alloc] init];
if(mailController!=nil) {
        mailController.mailComposeDelegate = self;
            [mailController setSubject:urSubject];
            [mailController setMessageBody:urBody isHTML:NO];
            [mailController addAttachmentData:urData mimeType:type fileName:urfileName];
}
[self presentModalViewController:mailController animated:YES];
[mailController release];
}

简单你要发送邮件的地方只需在你的方法中定义这段代码..... 但首先在viewController的.h文件中定义委托代表是MFMailComposeViewControllerDelegate 然后在按钮单击方法中编写此代码......

       MFMailComposeViewController* controller = [[MFMailComposeViewController alloc] init];
        controller.mailComposeDelegate = self;
        [controller setToRecipients:@"Recipients Name"];
        [controller setSubject:@"your subject"];
        [controller setMessageBody:@"Your Text Here for Mail" isHTML:YES]; 
        if (controller)
        {
            [self presentModalViewController:controller animated:YES];
            [controller release];
        }

然后你可以在你的ViewController.m文件中粘贴下面的mailComposerDelegate方法......

- (void)mailComposeController:(MFMailComposeViewController*)controller  
          didFinishWithResult:(MFMailComposeResult)result 
                        error:(NSError*)error;
{
    if (result == MFMailComposeResultSent) {
        NSLog(@"Mail Sent");
    }

    [self dismissModalViewControllerAnimated:YES];

}

如何在Root ViewController中调用邮件功能？
