Question

我正在尝试使用以下代码发送电子邮件 - 我没有收到任何错误，并且电子邮件客户端将加载，但它不会发送电子邮件：

- (IBAction)emailButtonPressed {
    MFMailComposeViewController *controller = [[MFMailComposeViewController alloc] init];

controller.mailComposeDelegate = self;

NSString *docsDir;
NSArray *dirPaths;
sqlite3_stmt    *statement;
// Get the documents directory
dirPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

docsDir = [dirPaths objectAtIndex:0];

// Build the path to the database file
databasePath = [[NSString alloc] initWithString: [docsDir stringByAppendingPathComponent: @"ral.db"]];

const char *dbpath = [databasePath UTF8String];

self.html = [NSMutableString stringWithFormat:@"<html><head></head><body>Key: <table> <tr> <td style='border: solid 1px #f75fea; text-align: center; background-color: #ed9ce6;'>&nbsp;&nbsp;X&nbsp;&nbsp;</td> </tr> </table> Start of Cycle,<table> <tr> <td style='border: solid 1px #f75fea; text-align: center;'>&nbsp;&nbsp;M&nbsp;&nbsp;</td> </tr> </table> Mild Pain, <table>  <tr> <td style='border: solid 1px #f75fea; text-align: center;'>&nbsp;&nbsp;S&nbsp;&nbsp;</td> </tr> </table> Severe Pain<br/><br/><br/><table><tr>"];

int i = 0;

if (sqlite3_open(dbpath, &ral) == SQLITE_OK)
{
    NSString *querySQL = [NSString stringWithFormat: @"SELECT * from DIARY order by _id"];

    const char *query_stmt = [querySQL UTF8String];

    if (sqlite3_prepare_v2(ral, query_stmt, -1, &statement, NULL) == SQLITE_OK)
    {
        while (sqlite3_step(statement) == SQLITE_ROW)
        {
            if ((i == 14) || (i == 28) || (i == 42) || (i == 56) || (i == 70) || (i == 84) || (i == 98) || (i == 112)) {
                [self.html appendString:@" </tr> <tr> "];
            }

            //create an image view
            NSMutableString *timeStamp = [[NSMutableString alloc] initWithUTF8String:(const char *) sqlite3_column_text(statement, 1)];

            NSString *timeStamp_  = [[NSString stringWithFormat:@"%@", timeStamp] substringToIndex:5];

            NSMutableString *periodStart = [[NSMutableString alloc] initWithUTF8String:(const char *) sqlite3_column_text(statement, 2)];
            NSMutableString *painValue = [[NSMutableString alloc] initWithUTF8String:(const char *) sqlite3_column_text(statement, 3)];
            [self.html appendString:[NSString stringWithFormat:@" <td> <table> <tr> <td style='font-family: arial; color:#777;'> %@ </td> </tr> ", timeStamp_]];

            [self.html appendString:[NSString stringWithFormat:@"<tr> <td style='border: solid 1px #f75fea; text-align: center; background-color: #ed9ce6; width: 20px; height: 20px;font-family: arial; color:#333;'>&nbsp;%@&nbsp;</td> </tr> ", periodStart]];

            [self.html appendString:[NSString stringWithFormat:@"<tr> <td style='border: solid 1px #f75fea; text-align: center; width: 20px; height: 20px;font-family: arial; color:#333;'>&nbsp;%@&nbsp;</td> </tr> </table> </td>", painValue]];

            i = i + 1;
        }
        sqlite3_finalize(statement);
    }
    sqlite3_close(ral);
}
[self.html appendString:@"</table></body></html>"];

NSString *tempHtml = self.html;

[controller setSubject:@"Pain diary"];
[controller setMessageBody:[NSString stringWithFormat: @"%@", tempHtml] isHTML:YES];

// Show email view
Class mailClass = (NSClassFromString(@"MFMailComposeViewController"));
if (mailClass != nil) {
    // We must always check whether the current device is configured for sending emails
    if ([mailClass canSendMail]) {
        [self presentModalViewController:controller animated:YES];
    } else {
        //do something
        NSLog(@"cant send mail");
    }
} else {
    //do something
    NSLog(@"class not instantiated");

}
}

有人能看出为什么会这样吗？

Answer 1

我意识到我需要从我的代码中捕获发送事件

就是这样

- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error
{
[self dismissModalViewControllerAnimated:YES];
}

iOS：电子邮件发送冻结了
