我有一個UITableCell,並且在那個單元上我有一個UITextBox,當單擊文本框而不是顯示鍵盤時,下面的代碼顯示UIDatePicker。但是我在定位UIDatePicker時遇到了問題。我需要它從頁面的最底部開始,目前它似乎從按下文本框的表格部分的頂部開始。該代碼在用戶單擊首選日期標籤時觸發。任何指針?我附加了一張圖片來顯示它當前正在渲染的位置。謝謝。UIDatePicker沒有顯示在UITable上的正確位置
- (IBAction)selectDateBegin:(id)sender {
//Disable Keyboard
[self.txtBookingDate resignFirstResponder];
//Disable Scrolling
[_tableForm setScrollEnabled:false];
if ([self.view viewWithTag:9]) {
return;
}
CGRect toolbarTargetFrame = CGRectMake(0, self.view.bounds.size.height-216-44, 320, 44);
CGRect datePickerTargetFrame = CGRectMake(0, self.view.bounds.size.height-216, 320, 216);
UIView *darkView = [[UIView alloc] initWithFrame:self.view.bounds];
darkView.alpha = 0;
darkView.backgroundColor = [UIColor blackColor];
darkView.tag = 9;
UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(dismissDatePicker:)] ;
[darkView addGestureRecognizer:tapGesture];
[self.view addSubview:darkView];
UIDatePicker *datePicker = [[UIDatePicker alloc] initWithFrame:CGRectMake(0, self.view.bounds.size.height+44, 320, 216)] ;
datePicker.tag = 10;
[datePicker addTarget:self action:@selector(changeDate:) forControlEvents:UIControlEventValueChanged];
[self.view addSubview:datePicker];
UIToolbar *toolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, self.view.bounds.size.height, 320, 44)];
toolBar.tag = 11;
toolBar.barStyle = UIBarStyleBlackTranslucent;
UIBarButtonItem *spacer = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(dismissDatePicker:)];
[toolBar setItems:[NSArray arrayWithObjects:spacer, doneButton, nil]];
[self.view addSubview:toolBar];
[UIView beginAnimations:@"MoveIn" context:nil];
toolBar.frame = toolbarTargetFrame;
datePicker.frame = datePickerTargetFrame;
darkView.alpha = 0.5;
[UIView commitAnimations];

謝謝@ Lolloz89虐待這樣做。 – MrBeanzy 2013-03-09 13:36:23
