If you are wondering how to get the text from textfield, and send it, you will need to use textfield.text
如果您想知道如何从 textfield 获取文本并发送它，您将需要使用 textfield.text
NSString *emailBody = textField.text;
[mailer setMessageBody:emailBody isHTML:NO];

There can be two way -
可以有两种方式——
You can create proprty for your text field, and then access like -
myTextField.textwhere you want.You can create a
NSStringproperty and set value in to this when text field has some text.
您可以为您的文本字段创建属性，然后像 -
myTextField.text您想要的那样访问。NSString当文本字段有一些文本时，您可以创建一个属性并为其设置值。

You can create the body of email as you want by appending the string with particular format Like User ID: 223984775(value from the textfieldUserID) Name: XYZ(value from the textfieldName) ......
您可以根据需要通过附加具有特定格式的字符串来创建电子邮件正文，例如用户 ID：223984775（来自 textfieldUserID 的值）名称：XYZ（来自 textfieldName 的值）......
You can do this by appending the string as the user moves to the next text field to enter.
您可以通过在用户移动到下一个要输入的文本字段时附加字符串来完成此操作。
Use Nsstring "stringWithFormat" method to append the data in the body. Use \n and \t to give a Tabular structure to the body of email. Use formatting too
使用 Nsstring "stringWithFormat" 方法在正文中附加数据。使用 \n 和 \t 为电子邮件正文提供表格结构。也使用格式
