ios - 更改模式对话框 ios 的大小

Question

如何更改模态对话框的大小？为什么这不起作用？

SlingDialogViewController *slingDialog = [[SlingDialogViewController alloc] init];

    slingDialog.modalPresentationStyle = UIModalPresentationFormSheet;
    slingDialog.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
    slingDialog.view.superview.frame = CGRectMake(0, 0, 900, 700);
    [self presentModalViewController:slingDialog animated:YES];

Answer 1

这样做:

SlingDialogViewController *slingDialog = [[SlingDialogViewController alloc] init];

slingDialog.modalPresentationStyle = UIModalPresentationFormSheet;
slingDialog.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;

[self presentViewController:navController animated:YES completion:nil];

slingDialog.view.superview.frame = CGRectMake(0, 0, 900, 700);
slingDialog.view.superview.center = self.view.center;

至少根据我的经验，首先调用 presentViewController:animated:completion 很重要。
