推荐答案
1.定义完成按钮(=返回键):
1.Define the done button (= return key):
textField.returnKeyType = UIReturnKeyDone;
2.添加动作监听器:
2.Add the action-listener:
[textField addTarget:self action:@selector(textFieldDoneEditing:) forControlEvents:UIControlEventEditingDidEndOnExit];
3.定义动作事件:
- (IBAction)textFieldDoneEditing:(id)sender {
[sender resignFirstResponder];
}
玩得开心!
编辑:
您可以在此处找到有关如何添加工具栏的详细说明与Next&上面的UITextField键盘:

Here you can find detailed instructions how to add a Toolbar with Next & Previous above UITextField Keyboard: http://www.randomsequence.com/articles/adding-a-toolbar-with-next-previous-above-uitextfield-keyboard-iphone/
EDIT2:
现在,我有一个很好的例子:这个视图扩展了UITextView在键盘上的添加与此UITextView关联的工具栏带有完成»按钮
Now, I have a really great example for you: "This view extends UITextView adding on top of the keyboard associated with this UITextView a toolbar with a « Done » Button"
我检查代码,它比第一个例子容易得多:
I check the code and it is a lot of easier than the first example:
EDIT3:
嗯,不,我不测试代码。但我现在要测试它!
Hmmm, no, I doesn't test to code. But I will test it now!
1.问题:正确的初始化。如果我在IB中添加UITextView,则会调用initWithCoder:
1.Problem: the right initialization. If I add the UITextView in IB, initWithCoder gets called:
- (id)init {
NSLog(@"init");
if (self = [super init]) {
//register a specific method on keyboard appearence
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];
}
return self;
}
- (id)initWithCoder:(NSCoder *)decoder {
NSLog(@"initWithCoder");
if (self = [super initWithCoder:decoder]) {
//register a specific method on keyboard appearence
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];
}
return self;
}
- (id)initWithFrame:(CGRect)frame {
NSLog(@"initWithFrame");
if (self = [super initWithFrame:frame]) {
//register a specific method on keyboard appearence
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];
}
return self;
}
2.问题:前缀UIKeyboard没有视图:
2.Problem: There's no view with the the Prefix "UIKeyboard":
for (UIWindow *keyboardWindow in [[UIApplication sharedApplication] windows]) {
NSLog(@"keyboardWindow = %@", keyboardWindow);
for (UIView *keyboard in [keyboardWindow subviews]) {
NSLog(@"keyboard = %@", keyboard);
if([[keyboard description] hasPrefix:@"<UIKeyboard"] == YES) {
// THERE'S NO VIEW 'UIKeyboard'!!!
}
}
}
代码不起作用,对不起......我不知道为什么没有UIKeyboard的观点......也许第一个例子会帮助你,你可以建立自己的解决方案。
The code doesn't work, I'm sorry... I don't know why there's no view "UIKeyboard"... Maybe the first example will help you at this point and you can build your own solution.
