UIAlertView和UIButton在白色背景上具有白色按钮

Question

After upgrading the dev iPhone 5 to iOS 8.1, all of the buttons and default labels on UINavigationBars and UIAlertViews started to appear on screen with white text.

I tried to resolve the problem with:

// UIView tints
[[UIView appearance] setTintColor:[UIColor blackColor]];
[[UIAlertView appearance] setTintColor:[UIColor blackColor]];
[[UINavigationBar appearance] setBarTintColor:[UIColor blackColor]];
[[UIBarButtonItem appearance] setTintColor:[UIColor whiteColor]];

This somehow solved the white buttons in most cases, but not all of them. I'm still having problems with the alert views appearing after receiving a notification in-app, with navigation bar buttons and labels.

Has anyone experienced this problem? And if possible has a solution?

Answer 1

One cannot customize the appearance of UIAlretView :

[[UIAlertView appearance] setTintColor:[UIColor blackColor]];

Check Apple notes in class reference :

Subclassing Notes

The UIAlertView class is intended to be used as-is and does not support subclassing. The view hierarchy for this class is private and must not be modified.
