ios - presentModalViewController:animated 已弃用

Question

我在 XCode 中收到警告：

'presentModalViewController:animated:' is deprecated: first deprecated in iOS 6.0

在这行代码上：

[self presentModalViewController:initialSettingsVC animated:YES];

我尝试按照文档中的建议将其替换为：

[self presentModalViewController:initialSettingsVC animated:YES completion:nil];

我现在在 XCode 中遇到错误：

'ViewController' 没有可见的@interface 声明选择器'presentModalViewController:animated:completion:'

有任何想法吗？

Answer 1

使用以下......

if ([self respondsToSelector:@selector(presentViewController:animated:completion:)]){
    [self presentViewController:test animated:YES completion:nil];
} else {
    [self presentModalViewController:test animated:YES];
}

代替

[self presentModalViewController:initialSettingsVC animated:YES completion:nil];

至

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

Answer 3

You want to use the following

- (void)presentViewController:(UIViewController *)viewControllerToPresent 
                      animated: (BOOL)flag completion:(void (^)(void))completion;

settting UIModalPresentationStyle and UIModalTransitionStyle for viewController in order to get the modal animation /presentation you're looking for
