iOS 应用内调用并发送邮件
- 目前有两种方法 mailto: 和 MFMailComposeViewController
1. 使用 mailto:
- 会跳转到应用外并打开系统邮件
NSURL *url = [NSURL URLWithString:@"mailto:yourEmail"];
if ([[UIApplication sharedApplication] canOpenURL:url]) {
[[UIApplication sharedApplication] openURL:url options:@{} completionHandler:nil];
} else {
NSLog(@"打开邮箱出现错误");
}
2. MFMailComposeViewController
- 该方式需要已设置好邮件账户，否则无法打开
- 可设置主题、收件人、抄送人、发送内容
- 首先需要导入 #import <MessageUI/MFMailComposeViewController.h>
#pragma mark - 发送邮件
- (void)sendEmail {
MFMailComposeViewController *mailVC = [MFMailComposeViewController new];
if (!mailVC) {
// 在设备还没有添加邮件账户的时候，为空
NSLog(@"暂未设置邮箱账户，请先到系统设置添加账户");
return;
}
//代理 MFMailComposeViewControllerDelegate
mailVC.mailComposeDelegate = self;
//邮件主题
[mailVC setSubject:@"反馈/建议"];
//收件人
[mailVC setToRecipients:@[@"yourEmail"]];
[self presentViewController:mailVC animated:YES completion:nil];
}
// 实现代理方法
- (void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error {
// MFMailComposeResultCancelled
// MFMailComposeResultSaved
// MFMailComposeResultSent
// MFMailComposeResultFailed
if (result == MFMailComposeResultSent) {
NSLog(@"发送成功");
} else if (result == MFMailComposeResultFailed) {
NSLog(@"发送失败");
}
[controller dismissViewControllerAnimated:YES completion:nil];
}
