iOS軟鍵盤遮擋UITableView內文字框問題

iOS軟鍵盤遮擋UITableView內文字框問題

1、註冊
UIKeyboardDidShowNotification/UIKeyboardDidHideNotification通知。

-(id) initWithNibName:(NSString*)nibNameOrNil bundle:nibBundleOrNil {    if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) {        // 寫在這裡，或者viewDidLoad        [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardShown:) name:UIKeyboardDidShowNotification object:nil];        [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardHidden:) name:UIKeyboardDidHideNotification object:nil];    }    return self;}-(void) dealloc {    [[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardDidShowNotification object:nil];    [[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardDidHideNotification object:nil];}

2、當通知到來，調整frame。

-(void) keyboardShown:(NSNotification*) notification {    _initialTVHeight = _tableView.frame.size.height;    CGRect initialFrame = [[[notification userInfo] objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue];    CGRect convertedFrame = [self.view convertRect:initialFrame fromView:nil];    CGRect tvFrame = _tableView.frame;    tvFrame.size.height = convertedFrame.origin.y;    _tableView.frame = tvFrame;}-(void) keyboardHidden:(NSNotification*) notification {    CGRect tvFrame = _tableView.frame;    tvFrame.size.height = _initialTVHeight;    [UIView beginAnimations:@TableViewDown context:NULL];    [UIView setAnimationDuration:0.3f];    _tableView.frame = tvFrame;    [UIView commitAnimations];}

3、觸發文字框，滾動tableView
-(void) textFieldDidBeginEditing:(UITextField *)textField {
NSIndexPath* path = [NSIndexPath indexPathForRow:row inSection:section];
[self performSelector:@selector(scrollToCell:) withObject:path afterDelay:0.5f];
}
-(void) scrollToCell:(NSIndexPath*) path {
[_tableView scrollToRowAtIndexPath:path atScrollPosition:UITableViewScrollPositionNone animated:YES];
}
