Xcode 每封邮件发送数据

我正在开发一个应用程序，但缺少一小部分。我准备了一个视图，以便您可以将数据插入UITextField，然后我可以通过电子邮件发送此信息。我尝试了很多方法

#import <UIKit/UIKit.h>
@interface RMAcpu : UIViewController <UITextFieldDelegate> 
@property  IBOutlet UITextField *prodotto;
@property  IBOutlet UITextField *seriale;
@property  IBOutlet UITextField *cfiva;
@property  IBOutlet UITextField *email;
@property  IBOutlet UITextField *problema;
- (IBAction)inviodati:(id)sender;
@end

除非实现自己的SMTP客户端，否则无法直接从应用程序发送电子邮件。遵循此方法的当前项目是

如果不想以这种方式尝试，则需要使用来自

MessageUI

框架的。这将允许您创建电子邮件模板并预填充收件人、主题和邮件正文等字段，但用户必须手动点击发送按钮

我删除了意大利语，但它在这里没有任何作用，但请您准确说明问题/问题是什么？我正在尝试使用苹果样本。我已通过MFMailComposeViewController:[mail setMessageBody:@“PRODOTTO:\n\n样本：\n\nCF/P.IVA:\n\nEMAIL:\n\n具体问题：\n\n\n\n1.Danni da caduta\n2.eventiali sigilli rotti\n3.Viti forzate”isHTML:NO]；
