// 1、创建UITextView

UITextView* tv = [[UITextView alloc] initWithFrame:CGRectMake(10, 10, 300, 200)];

[tv setFont:[UIFont systemFontOfSize:19.0]];

tv.tag = 1001;

tv.returnKeyType = UIReturnKeyNext; // 下一行

tv.delegate = self;

[self.view addSubview:tv];

// 2、键盘上方附加一个toolbar，toolbar上有个完成按钮

UIToolbar* keyboardDoneButtonView = [[UIToolbar alloc] init];

keyboardDoneButtonView.barStyle = UIBarStyleBlack;

keyboardDoneButtonView.translucent = YES;

keyboardDoneButtonView.tintColor = nil;

[keyboardDoneButtonView sizeToFit];

// toolbar上的2个按钮

UIBarButtonItem *SpaceButton=[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace

target:nil action:nil]; // 让完成按钮显示在右侧

UIBarButtonItem* doneButton = [[UIBarButtonItem alloc] initWithTitle:@"完成"

style:UIBarButtonItemStyleBordered target:self

action:@selector(pickerDoneClicked)];

[keyboardDoneButtonView setItems:[NSArray arrayWithObjects:SpaceButton, doneButton, nil]];

tv.inputAccessoryView = keyboardDoneButtonView;

// 3、键盘上方附加的完成按钮触发函数

-(void)pickerDoneClicked

{

UITextView* view = (UITextView*)[self.view viewWithTag:1001];

[view resignFirstResponder];

}
