我有这样的起始视图:
屏幕的前半部分是Google地图,后半部分是UITableview,在标题单元格中有一个UISearchbar。
当我点击搜索栏时,这会在大屏幕上发生,但在小屏幕上,我的uisearchbar会被键盘覆盖。
正如您所看到的,当键盘显示时,搜索栏会向下移动一点点。我不想要那个。它应该推动一切,以便可以看到Tableview。
我遵循了有关contentInset的教程。但它没有做任何事情。
- (void)viewDidLoad
{
[super viewDidLoad];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(keyboardWillShow:)
name:UIKeyboardWillShowNotification
object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(keyboardWillHide:)
name:UIKeyboardWillHideNotification
object:nil];
}
- (void) dealloc
{
[[NSNotificationCenter defaultCenter] removeObserver:self];
}
- (void)keyboardWillShow:(NSNotification *)notification
{
NSLog(@"KeyboardWillshow");
// Step 1: Get the size of the keyboard.
CGSize keyboardSize = [[[notification userInfo] objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
// Step 2: Adjust the bottom content inset of your scroll view by the keyboard height.
UIEdgeInsets contentInsets = UIEdgeInsetsMake(0.0, 0.0, keyboardSize.height, 0.0);
self.tableView.contentInset = contentInsets;
self.tableView.scrollIndicatorInsets = contentInsets;
// Step 3: Scroll the target text field into view.
CGRect aRect = self.view.frame;
aRect.size.height -= keyboardSize.height;
if (!CGRectContainsPoint(aRect, _searchBar.frame.origin) ) {
CGPoint scrollPoint = CGPointMake(0.0, _searchBar.frame.origin.y - (keyboardSize.height-15));
[self.tableView setContentOffset:scrollPoint animated:YES];
NSLog(@"Scrolled");
}
}
- (void)keyboardWillHide:(NSNotification *)notification
{
UIEdgeInsets contentInsets = UIEdgeInsetsZero;
self.tableView.contentInset = contentInsets;
self.tableView.scrollIndicatorInsets = contentInsets;
}
它出现在打印滚动的if测试中。但仍然没有任何反应。
其中_searchBar是我的UISearchbar变量。
有人有想法吗?
编辑:
解决了问题,除了UISearchbar跳转crapy时点击它。这会产生一个像你在屏幕截图中看到的差距:

请参阅下面的示例。
- (void)keyboardWasShown:(NSNotification*)aNotification
{
NSDictionary* info = [aNotification userInfo];
CGSize kbSize = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
CGRect aRect = self.view.frame;
aRect.size.height -= kbSize.height;
float height =150;
float yPoint = aRect.size.height-height;
[self.tblSearch setFrame:CGRectMake(self.tblSearch.frame.origin.x
, yPoint, self.tblSearch.frame.size.width, height)];
}

如果您的搜索栏,tableview和mapview都放在视图中,
并且你想在keyboardWillshow,
时推送tableview和搜索栏您应该更新frame
而不是contentInset
。
