Obj C - 在触摸UIView时辞职第一响应者
当触摸屏幕时，我试图让键盘消失，这个问题在stackoverflow上得到了解决。由于这里有一个线程，当按下回车键时，我能够让键盘消失。我没有运气背景触摸辞职第一响应者。正在输入该方法，我在方法中有一个NSLog说“在backgroundTouched中”，但键盘仍在那里。
我试过让UIView成为一个UIControl类，所以我可以使用触摸事件。
journalComment是一个UITextView。
-(IBAction)backgroundTouched:(id)sender
{
[journalComment resignFirstResponder];
NSLog(@ "in backgroundTouched");
}
-(BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range
replacementText:(NSString *)text
{
// Any new character added is passed in as the "text" parameter
if ([text isEqualToString:@"n"]) {
// Be sure to test for equality using the "isEqualToString" message
[textView resignFirstResponder];
// Return FALSE so that the final 'n' character doesn't get added
return FALSE;
}
// For any other character return TRUE so that the text gets added to the view
return TRUE;
}

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{ [yourtextfield resignFirstResponder]; // you can have multiple textfields here }俯乡骚钵皆
- (void)viewDidLoad{ UITapGestureRecognizer* tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tap:)]; tapRecognizer.delegate = self; [self.view addGestureRecognizer:tapRecognizer]; }- (void)tap:(id)sender { // use to make the view or any subview that is the first responder resign (optionally force) [[self view] endEditing:YES]; }
