将光标放在MFMailComposeViewController的正文部分中的两行之后

Question

我在我的MFMailComposeViewController身体部位使用光标

- (BOOL) setMFMailFieldAsFirstResponder:(UIView*)view mfMailField:(NSString*)field{

for (UIView *subview in view.subviews) {



    NSString *className = [NSString stringWithFormat:@"%@", [subview class]];
    NSLog(@"SubView -- %@ --- %@",className,field);

    if ([className isEqualToString:field])

    {

        //Found the sub view we need to set as first responder

        [subview becomeFirstResponder];

        return YES;

    }



    if ([subview.subviews count] > 0) {

        if ([self setMFMailFieldAsFirstResponder:subview mfMailField:field]){

            //Field was found and made first responder in a subview

           return YES;

        }

    }

}



//field not found in this view.

return NO;

}

但是它会在身体部位的第一个字符上显示光标。如果想要光标在两行之后，比如

这是邮件的身体部分 ，我想在此信息的两行后面找到光标。

我正在使用[picker setMessageBody:emailBody isHTML:YES];设置正文部分，我需要isHTML是。

Answer 1

试试这个，

NSString *emailBody=[NSString stringWithFormat:@"%@<br>Hooray, This is my 2 lines before curser:<br><br>"];
emailbody = [emailBody stringByAppendingString:@"Whatever string or curser you want"];

[picker setMessageBody:emailBody isHTML:YES];
