话不多说，直接上代码：
1、//点击空白处，键盘收回
UIControl *co = [[UIControl alloc]initWithFrame:CGRectMake(0,64,ScreenWidth,ScreenHeight)];
[co addTarget:self action:@selector(coClick) forControlEvents:UIControlEventTouchUpInside];
[_tableView addSubview:co];
[_tableView sendSubviewToBack:co];
-(void)coClick{
[self.view endEditing:YES];
}
2、通知监听键盘
//监听键盘弹出
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];
//监听键盘隐藏
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillHide:) name:UIKeyboardWillHideNotification object:nil];
//键盘显示监听方法
- (void)keyboardWillShow:(NSNotification *)noti
{
if (IS_IPHONE_4_SCREEN || IS_IPHONE_5_SCREEN) {
[UIView animateWithDuration:0.25 animations:^{
self.view.transform = CGAffineTransformMakeTranslation(0, -100.0);
} completion:^(BOOL finished) {
}];
}
UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(keyboardHide:)];
//设置成NO表示当前控件响应后会传播到其他控件上，默认为YES。
tapGestureRecognizer.cancelsTouchesInView = NO;
//将触摸事件添加到当前view
[self.view addGestureRecognizer:tapGestureRecognizer];
}
//键盘隐藏监听方法
- (void)keyboardWillHide:(NSNotification *)noti
{
if (IS_IPHONE_4_SCREEN || IS_IPHONE_5_SCREEN) {
[UIView animateWithDuration:0.25 animations:^{
self.view.transform = CGAffineTransformIdentity;
} completion:^(BOOL finished) {
}];
}
}
3、textField 点击return按键，键盘收回(前提要遵守协议)
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
//回收键盘,取消第一响应者
[textField resignFirstResponder];
[UIView animateWithDuration:0.25 animations:^{
_tableView.frame = CGRectMake(0, 0, YJScreenWidth, YJScreenHeight);
}];
return YES;
}
4、textView点击return按键，键盘收回
- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text {
if([text isEqualToString:@"\n"]) {
[textView resignFirstResponder];
return NO;
}
return YES;
}
