我想阅读一些远程pdf,所以我创建了一个包含网址的NSArray
,但是当我尝试阅读它时,我得到了这个:
Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayI objectAtIndex:]: index 2 beyond bounds [0 .. 0]'
这是我的代码
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
if ([[segue identifier] isEqualToString:@"CircularDetail"]) {
CircularDetailViewController *circulardetail = [self.storyboard instantiateViewControllerWithIdentifier:@"CircularControllerDetail"];
NSIndexPath *myIndexPath = [self.tableView indexPathForSelectedRow];
int row = [myIndexPath row];
circulardetail.DetailModal = [NSArray arrayWithObjects:_SeccionCirculares[row], _circularfecha[row], _circularTitulo[row], _circularURL[row], nil];
[self presentViewController:circulardetail animated:YES completion:nil];
}
}
在细节中我有这个
- (void) loadRemotePdf
{
NSURL *myUrl = [NSURL URLWithString:[_DetailModal objectAtIndex:3]];
NSURLRequest *myRequest = [NSURLRequest requestWithURL:myUrl];
[self.webview loadRequest:myRequest];
}
答案 0 :(得分:0)
CircularDetailViewController *circulardetail =
[self.storyboard instantiateViewControllerWithIdentifier:@"CircularControllerDetail"];
创建视图控制器的 new 实例。你可能想要
CircularDetailViewController *circulardetail =
(CircularDetailViewController *)[segue destinationViewController];
代替。
您无需致电presentViewController
进行segue转换。
您还应该注意
参数列表中的任何nil
对象
circulardetail.DetailModal = [NSArray arrayWithObjects:...];
终止列表,因此数组可能比您预期的要短。
