如何使用iPhone SDK获取视图上的控件列表? [英] How get the list of controls on a view with iPhone SDK?

问题描述

I wanna do something like the safari app when fill a form, so when the user see the keyboard do next and move to next control.

现在，我如何获得下一个文本控件?

Now, how I get the next text control?

推荐答案

您可以在 textFieldShouldReturn:中处理此类行为 每当用户点击回车键时，这都将使您的注意力集中在表单上.

You can handle behaviour like this in textFieldShouldReturn: This should move your focus along the form for you each time the user hits return.

- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
    if(textField == field1) {
        [field1 resignFirstResponder];   
        [field2 becomeFirstResponder];    
        // do stuff with field1 text
    } else if(textField == field2) {
        [field2 resignFirstResponder];   
        [field3 becomeFirstResponder];
        // do stuff with field2 text
    } // and so on

}
