当我激活UITextField
时会出现以下问题(如果我只显示几张图片,请尝试以UIView which is nested within my
UITableViewController作为页脚。

据我所知,当UITextField成为第一个响应者时(即将键盘添加到视图中),您试图移动整个视图?如果是这种情况,我会在UITextField委托方法中添加代码:
#define VIEW_TAG 12345
#define kKeyboardOffsetY 80.0f
- (void)textFieldDidBeginEditing:(UITextField *)textField {
// get a reference to the view you want to move when editing begins
// which can be done by setting the tag of the container view to VIEW_TAG
UIView *containerView = (UIView *)[self.view viewWithTag:VIEW_TAG];
[UIView animateWithDuration:0.3 animations:^{
containerView.frame = CGRectMake(0.0f, -kKeyboardOffsetY, containerView.frame.size.width, containerView.frame.size.height);
}];
}
- (void)textFieldDidEndEditing:(UITextField *)textField {
UIView *containerView = (UIView *)[self.view viewWithTag:VIEW_TAG];
[UIView animateWithDuration:0.3 animations:^{
containerView.frame = CGRectMake(0.0f, self.view.frame.origin.y, containerView.frame.size.width, containerView.frame.size.height);
}];
}
您不必使用'viewWithTag'方法,只需要获取对容器视图的引用,也可以通过迭代子视图来完成。

键盘出现时调整桌面视图的高度。
以下是我的一个项目的例子。
首先:听一下键盘事件:
-(void) viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
//Be informed of keyboard
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardDidShow:) name:UIKeyboardDidShowNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillHide:) name:UIKeyboardDidHideNotification object:nil];
}
#pragma mark keyboard
- (void)keyboardDidShow:(NSNotification *)notification
{
NSDictionary *userInfo = [notification userInfo];
CGSize size = [[userInfo objectForKey: UIKeyboardFrameEndUserInfoKey] CGRectValue].size;
CGRect frame = CGRectMake(self.tableView.frame.origin.x,
self.tableView.frame.origin.y,
self.tableView.frame.size.width,
self.tableView.frame.size.height - size.height);
self.tableView.frame = frame;
}
- (void)keyboardWillHide:(NSNotification *)notification
{
NSDictionary *userInfo = [notification userInfo];
CGSize size = [[userInfo objectForKey: UIKeyboardFrameEndUserInfoKey] CGRectValue].size;
self.tableView.frame = CGRectMake(self.tableView.frame.origin.x,
self.tableView.frame.origin.y,
self.tableView.frame.size.width,
self.tableView.frame.size.height + size.height);
}

我是这样做的,它是动画的所以看起来不错。
键盘高度为216px,停止时需要0.25秒。
以下是我的代码中的部分:
-(void)textFieldDidBeginEditing:(UITextField *)textField {
if (textField.tag == 2) {
void (^a)(void) = ^(void){
[UIView animateWithDuration:.25 animations:^{
RegNrView.frame = CGRectMake(0, -216, 320, 460);
}
completion:nil];
};
[[NSOperationQueue mainQueue] addOperationWithBlock:a];
}
}
这使得UIView和键盘在同一时间移动。
