Я конвертирую все свои UIActionSheet
и UIAlertView
с UIAlertController
.UIAlertController Невозможно удовлетворить ограничения
Моя проблема в том, что я пытаюсь представить UIAlertController
стиля ActionSheet. Вот мой код:
UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"Title"
message:@"My message"
preferredStyle:UIAlertControllerStyleActionSheet];
UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleCancel handler:nil];
[alert addAction:cancelAction];
UIAlertAction *OKAction = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:nil];
[alert addAction:OKAction];
UIAlertAction *destroyAction = [UIAlertAction actionWithTitle:@"Destroy" style:UIAlertActionStyleDestructive handler:nil];
[alert addAction:destroyAction];
UIPopoverPresentationController *popPresenter = [alert popoverPresentationController];
popPresenter.sourceView = self.view;
popPresenter.sourceRect = self.view.bounds;
[self presentViewController:alert animated:YES completion:nil];
Здесь ошибка:
Unable to simultaneously satisfy constraints.
Probably at least one of the constraints in the following list is one you
don't want. Try this:
(1) look at each constraint and try to figure out which you don't expect;
(2) find the code that added the unwanted constraint or constraints and fix it.
(Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property
translatesAutoresizingMaskIntoConstraints)
(
"<NSLayoutConstraint:0x7c00ab40 H:[UIView:0x7c0764c0(304)]>",
"<NSLayoutConstraint:0x7b6c7f80 _UIAlertControllerView:0x7b6c2e50'title'.width >= UIView:0x7b6c3230.width>",
"<NSLayoutConstraint:0x7ccdfe40 _UIAlertControllerView:0x7b6c2e50'title'.width == UIView:0x7b6efbe0.width>",
"<NSAutoresizingMaskLayoutConstraint:0x7c33b9d0 h=--& v=--& H:[UIView:0x7c1094e0(0)]>"
)
Will attempt to recover by breaking constraint
<NSLayoutConstraint:0x7c00ab40 H:[UIView:0x7c0764c0(304)]>
Спасибо всем.
Ошибка указывает на то, что вы пытаетесь настроить 'alert.view.translatesAutoresizingMaskIntoConstraints' на' NO'. Вы пробовали это? – n00neimp0rtant
Да, я пробовал '[alert.view setTranslatesAutoresizingMaskIntoConstraints: NO];', same issue –
Вы когда-нибудь это понимали? У меня та же проблема. – Fil
