我更喜欢:

@interface MyViewController : UIViewController
@property (nonatomic, retain) IBOutletCollection(UIView) NSArray *inputFields;
@end

在NIB文件中，我以所需的顺序将textFields钩子到这个inputFields数组中。之后，我做了一个简单的UITextField的索引测试，报告用户点击返回:

// for UITextField
-(BOOL)textFieldShouldReturn:(UITextField*)textField {
    NSUInteger index = [_inputFields indexOfObject:textField];
    index++;
    if (index < _inputFields.count) {
        UIView *v = [_inputFields objectAtIndex:index];
        [v becomeFirstResponder];
    }
    return NO;
}

// for UITextView
-(BOOL)textView:(UITextView*)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString*)text {
    if ([@"\n" isEqualToString:text]) {
        NSUInteger index = [_inputFields indexOfObject:textView];
        index++;
        if (index < _inputFields.count) {
            UIView *v = [_inputFields objectAtIndex:index];
            [v becomeFirstResponder];
        } else {
            [self.view endEditing:YES];
        }
        return NO;
    }
    return YES;
}

在textFieldShouldReturn你应该检查你目前的文本域不是最后一个，当他们点击下一步，如果不是不要解散键盘..

我用Michael G. Emmons的答案已经有一年了，效果很好。我最近注意到，立即调用resignFirstResponder，然后立即调用becomeFirstResponder会导致键盘“故障”，消失，然后立即出现。我稍微改变了他的版本，跳过resignFirstResponder如果nextField是可用的。

- (BOOL)textFieldShouldReturn:(UITextField *)textField
{ 

    if ([textField isKindOfClass:[NRTextField class]])
    {
        NRTextField *nText = (NRTextField*)textField;
        if ([nText nextField] != nil){
            dispatch_async(dispatch_get_main_queue(),
                           ^ { [[nText nextField] becomeFirstResponder]; });

        }
        else{
            [textField resignFirstResponder];
        }
    }
    else{
        [textField resignFirstResponder];
    }

    return true;

}

这是一个简单的解决方案在swift，没有标签使用，没有故事板技巧…

只需使用这个扩展:

extension UITextField{

    func nextTextFieldField() -> UITextField?{
        //field to return
        var returnField : UITextField?
        if self.superview != nil{
            //for each view in superview
            for (_, view) in self.superview!.subviews.enumerate(){
                //if subview is a text's field
                if view.isKindOfClass(UITextField){
                    //cast curent view as text field
                    let currentTextField = view as! UITextField
                    //if text field is after the current one
                    if currentTextField.frame.origin.y > self.frame.origin.y{
                        //if there is no text field to return already
                        if returnField == nil {
                            //set as default return
                            returnField = currentTextField
                        }
                            //else if this this less far than the other
                        else if currentTextField.frame.origin.y < returnField!.frame.origin.y{
                            //this is the field to return
                            returnField = currentTextField
                        }
                    }
                }
            }
        }
        //end of the mdethod
        return returnField
    }

}

并调用它像这样(例如)与你的textfield委托:

func textFieldShouldReturn(textField: UITextField) -> Bool {
    textField.resignFirstResponder()
    textField.nextTextFieldField()?.becomeFirstResponder()
    return true
}

退出一个文本字段后，调用[otherTextField becomeFirstResponder]，下一个字段获得焦点。

这实际上是一个棘手的问题，因为通常你还想滚动屏幕或以其他方式调整文本字段的位置，以便在编辑时容易看到。只要确保做大量的测试，以不同的方式进入和退出文本字段，并提前离开(总是给用户一个选项，取消键盘，而不是进入下一个字段，通常在导航栏中有“完成”)
