ios - iOS 10.3 中的备用图标 : avoid notification dialog for icon change

Question

我正在使用这个新功能，当对事件应用程序进行更改时，会显示一个通知对话框，说明图标已被修改。 如何禁用此对话框？

如果你不介意使用私有(private)方法，你可以试试下面的代码。

- (void)lc_setAlternateIconName:(NSString*)iconName
{
    //anti apple private method call analyse
    if ([[UIApplication sharedApplication] respondsToSelector:@selector(supportsAlternateIcons)] && 
        [[UIApplication sharedApplication] supportsAlternateIcons])
    {
        NSMutableString *selectorString = [[NSMutableString alloc] initWithCapacity:40];
        [selectorString appendString:@"_setAlternate"];
        [selectorString appendString:@"IconName:"];
        [selectorString appendString:@"completionHandler:"];

        SEL selector = NSSelectorFromString(selectorString);
        IMP imp = [[UIApplication sharedApplication] methodForSelector:selector];
        void (*func)(id, SEL, id, id) = (void *)imp;
        if (func)
        {
            func([UIApplication sharedApplication], selector, iconName, ^(NSError * _Nullable error) {});
        }
    }
}
