- (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]; 
}

2.如果你的textview里不用回車鍵，可以把回車鍵當做退出鍵盤的響應鍵。

-(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回車鍵還是使用彈出鍵盤里的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]; 
}
