1、点击固定的按钮关闭键盘
-(BOOL)textFieldShouldReturn:(UITextField *)textField
{
[textField resignFirstResponder];
return YES;
}
-(BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text
{
if([text isEqualToString:@"\n"])
{
[textView resignFirstResponder];
return YES;
}
return YES;
}
2、点击其他关闭键盘
- (void)viewDidLoad
{
[super viewDidLoad];
UITapGestureRecognizer *tapGr = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(viewTapped:)];
tapGr.cancelsTouchesInView = NO;
[self.view addGestureRecognizer:tapGr];
}
-(void)viewTapped:(UITapGestureRecognizer*)tapGr{
[self.textField1 resignFirstResponder];
}
