视图中有三个textFields
,如下图所示:
当我点击其中一个文本字段时,一个textField
可以becomeFirstResponder
,然后键盘出现。不会崩溃。
当我点击“完成”时或者制作其中一个文本字段
resignFirstResponder
,键盘会消失。但是什么时候
键盘消失了,我的应用程序崩溃了。

iOS 9: [UIInputWindowController parentViewController]:发送到解除分配的实例0x7fde7c004400的消息

使用此代码:
and also set the delegates of the text fields
- (BOOL)textFieldShouldReturn:(UITextField *)theTextField {
if (theTextField == yourTextFieldOne) {
[theTextField becomeFirstResponder];
} else if (theTextField == yourTextFieldTwo) {
[self.textPassword becomeFirstResponder];
}else if (theTextField == yourTextFieldThree) {
[theTextField resignFirstResponder];
}
return YES;
}

// 设置导航条
- (void)setupNav {
UILabel *titleLabel = [[UILabel alloc] init];
titleLabel.text = @"忘记密码";
titleLabel.textColor = HexColor(0x795033);
// titleLabel.font = HNLightFont(20.0);
titleLabel.font = [UIFont systemFontOfSize:20.0];
[titleLabel sizeToFit];
self.navigationItem.titleView = titleLabel;
// 这2句代码起到向下偏移64的作用
self.edgesForExtendedLayout = UIRectEdgeNone;
self.automaticallyAdjustsScrollViewInsets = NO;
}
