像这样编辑文本字段时，此控件可以在键盘上方显示工具栏

Answer 2

UIBarButtonItem *prevButton = [[UIBarButtonItem alloc] initWithTitle:@"Prev" style:UIBarButtonItemStyleBordered target:self action:@selector(prevButtonPressed:)];    
UIBarButtonItem *nextButton = [[UIBarButtonItem alloc] initWithTitle:@"Next" style:UIBarButtonItemStyleBordered target:self action:@selector(nextButtonPressed:)];
UIBarButtonItem *flexibleSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(doneButtonPressed:)]

UIToolbar *toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
toolbar.barStyle = UIBarStyleBlackTranslucent;
[toolbar setItems:@[prevButton, nextButton, flexibleSpace, doneButton]];

UITextView *textView = [[UITextView alloc] inithWithFrame:CGRectMake(x, y, width, height)];
textView.inputAccessoryView = toolbar;

您可以使用 aUISegmentedControl创建类似于 @adali 发布的 Prev/Next 效果
