1.如果你程式是有導覽列的，可以在導覽列上面加多一個Done的按鈕，用來退出鍵盤，當然要先實UITextViewDelegate。
代碼如下：
- (void)textViewDidBeginEditing:(UITextView *)textView {
UIBarButtonItem *done = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(leaveEditMode)] autorelease];
self.navigationItem.rightBarButtonItem = done;
}
- (void)textViewDidEndEditing:(UITextView *)textView {
self.navigationItem.rightBarButtonItem = nil;
- (void)leaveEditMode {
[self.textView resignFirstResponder];
效果類似這樣：
2.如果你的textview裡不用Enter鍵，可以把Enter鍵當做退出鍵盤的響應鍵。
#pragma mark - UITextView Delegate Methods
-(BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text
{
if ([text isEqualToString:@"\n"]) {
[textView resignFirstResponder];
return NO;
}
return YES;
這樣無論你是使用電腦鍵盤上的Enter鍵還是使用彈出鍵盤裡的return鍵都可以達到退出鍵盤的效果。
3.第三種方法感覺效果比上面兩種都好，就是在彈出的鍵盤上面加一個view來放置退出鍵盤的Done按鈕。
UIToolbar * topView = [[UIToolbar alloc]initWithFrame:CGRectMake(0, 0, 320, 30)];
[topView setBarStyle:UIBarStyleBlack];
UIBarButtonItem * helloButton = [[UIBarButtonItem alloc]initWithTitle:@"Hello" style:UIBarButtonItemStyleBordered target:self action:nil];
UIBarButtonItem * btnSpace = [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];
UIBarButtonItem * doneButton = [[UIBarButtonItem alloc]initWithTitle:@"Done" style:UIBarButtonItemStyleDone target:self action:@selector(dismissKeyBoard)];
NSArray * buttonsArray = [NSArray arrayWithObjects:helloButton,btnSpace,doneButton,nil];
[doneButton release];
[btnSpace release];
[helloButton release];
[topView setItems:buttonsArray];
[tvTextView setInputAccessoryView:topView];
-(IBAction)dismissKeyBoard
[tvTextView resignFirstResponder];
主要是使用了uitextview的InputAccessoryView的屬性來達到這樣的效果，下面是效果圖：
