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

Question

我在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;

}

但它在身体部位的第一个字符上显示光标。如果想要两行之后的光标，例如

这是邮件的正文部分，我希望光标在此消息的两行之后。

我正在使用[picker setMessageBody:emailBody isHTML:YES];来设置身体部位，我需要isHTML是。

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];
