问题描述
在一个UITextView上隐藏键盘,有方法:
On a UITextView to hide the keyboard, there is the method:
... textfield.returnKeyType = UIReturnKeyDone; textfield.delegate = self; .... -(BOOL)textFieldShouldReturn:(UITextField *)textField { [textField resignFirstResponder]; return YES; }
但是如果我想将完成"按钮留给返回"并添加一个隐藏键盘的按钮,我该怎么办?
but if I want to leave the button "done" to the "return" and add a button to hide the keyboard, how do I?
推荐答案
您可以分配一个带有按钮的工具栏,该按钮可作为文本字段的 inputAccessoryView 关闭键盘.一个简单的例子是,
You can assign a toolbar with a button that dismisses the keyboard as the text field's inputAccessoryView. A quick example would be,
UIBarButtonItem *barButton = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:textField action:@selector(resignFirstResponder)] autorelease]; UIToolbar *toolbar = [[[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)] autorelease]; toolbar.items = [NSArray arrayWithObject:barButton]; textField.inputAccessoryView = toolbar;
