单击按钮时,我将显示一个弹出视图,它是一个表格视图。
一切似乎都正常,视图显示,但不到一秒钟就消失了。
表格视图包含一个字符串列表,我将表格单元设置为显示复选标记。
我注意到该表显示了在它显示的瞬间检查的所有项目
任何人都知道我错过了什么。
谢谢
哈桑
显示弹出框的代码
- (void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([segue.identifier isEqualToString:@"WholesalersList"]){
AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
WholesalersViewController *vc = segue.destinationViewController;
vc.wholesalers = [appDelegate.wholesalers mutableCopy];
if ([segue isKindOfClass:[UIStoryboardPopoverSegue class]]){
self.wholesalersPopoverController = [(UIStoryboardPopoverSegue *)segue popoverController];
[self.wholesalersPopoverController setPopoverContentSize:CGSizeMake(334, 334)];
//[self.wholesalersPopoverController setDelegate:self];
}
}
}
