将光标移动到UITextField的开头 [英] Moving the cursor to the beginning of UITextField

问题描述

有没有办法让光标位于UITextField的开头？

Is there a way to make the cursor be at the start of a UITextField?

当我用内容显示控件时，光标位于字符串的末尾。我想把它移到开头。

When I display the control with content, the cursor is placed at the end of the string. I'd like to move it to the beginning.

推荐答案

UITextField 符合 UITextInput 协议，该协议提供允许您控制所选范围的方法。这适用于我的测试：

UITextField conforms to the UITextInput protocol, which provides methods that let you control the selected range. This works in my testing:

-(void)textFieldDidBeginEditing:(UITextField *)textField {
    textField.selectedTextRange = [textField
        textRangeFromPosition:textField.beginningOfDocument
        toPosition:textField.beginningOfDocument];
}
