beforeDismissViewControllerAnimated.m

%hook UIAlertController
// @property (nonatomic, readonly) NSArray<UIAlertAction *> *actions;
- (void)viewDidAppear:(BOOL)animated {
	%orig;
	NSLog(@"sb 弹框 title :%@ message:%@",[self title],[self message]);
	if (/* condition */ [[self title] isEqualToString:@"未安装 SIM 卡"])
	{
		     [self dismissViewControllerAnimated:YES completion:nil];
	}else if( [[self title] isEqualToString:KNEventNeedConniTunes]){
		NSLog(@"delete %@",KNEventNeedConniTunes);
		     [self dismissViewControllerAnimated:YES completion:nil];// 最好将此代码封装成block， 设置一个全局的字段，用于存储block，key 为对应的title
		     // 根据title 从存储的block数据中获取对应的block执行，这样将使此方法的代码更精简
	}
}

KNKNCFUserNotificationHandlerUIAlertControllerObjectKey.m

// 优化之后的代码
	NSString *AlertHeader =  [self title];
		NSLog(@"sb 弹框 title :%@ message:%@",AlertHeader,[self message]);
	    KNKNCFUserNotificationHandler handler = KNGHandlers[AlertHeader];//获取对应的block
    if (handler) {// 存在之前定义block就执行
// @{key：value，key：value...}
    	NSDictionary* dict =  @{KNKNCFUserNotificationHandlerUIAlertControllerObjectKey:self};
        id res = handler(dict);// 获取block的返回结果, 把自己传递给外界
        if (res){
        	NSLog(@"block res: %@",res);
            return ;//返回结果
        }
    }
    return;

请问下，你那边消除了SB弹窗之后，会出现界面无响应的情况吗？我这边环境是IOS8系统
