UIApplication didReceiveRemoteNotification，显示应用内横幅

【问题描述】：

我想在我的应用玩游戏期间显示应用内横幅通知，而不是我当前的UIAlertView

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
    
    if (application.applicationState == UIApplicationStateActive )
    
         // Show Alert ->
         // UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:NSLocalizedString(@"Did receive a Remote Notification", nil)
         // message:[apsInfo objectForKey:@"alert"]
         // delegate:self
         // cancelButtonTitle:NSLocalizedString(@"OK", nil)
         // otherButtonTitles:nil];
         // [alertView show];
         // [alertView release];

         // Show Banner Notification
    

这是我想要实现的示例：

你试过什么？我建议使用带有多行 UILabel 的 UIView

谢谢。部队231。这对我有好处。

与您发布的不太一样，但有一个不错的 github 项目：github.com/toursprung/TSMessages 也可用作 cocoapods。

【参考方案1】：

#define BANNER_HEIGHT 66.0    

  if (!showingNotification) 
        showingNotification = YES;

        // retrieve message from your actual notification here
       NSString *message = @"Showing notification";

        UIToolbar *newmessageBannerView = [[UIToolbar alloc] initWithFrame:CGRectMake(0, -BANNER_HEIGHT, self.view.frame.size.width, BANNER_HEIGHT)];
        newmessageBannerView.translucent = YES;

        newmessageBannerView.barStyle = UIBarStyleBlack;
        newmessageBannerView.backgroundColor = [UIColor blackColor];

        UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(10.0, 33.0, 16.0, 16.0)];
        imageView.image = [UIImage imageNamed:@"icon_72"];
        [newmessageBannerView addSubview:imageView];
        [self.view addSubview:newmessageBannerView];

        UILabel *bannerLabel = [[UILabel alloc] initWithFrame:CGRectMake(40.0, 30.0, 320.0, 22.0)];
        bannerLabel.textAlignment =  NSTextAlignmentLeft;
        bannerLabel.textColor = [UIColor whiteColor];
        bannerLabel.font = [UIFont systemFontOfSize:17.0];
        bannerLabel.text = message;
        bannerLabel.backgroundColor = [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.0];
        bannerLabel.adjustsFontSizeToFitWidth = YES;
        [newmessageBannerView addSubview:bannerLabel];

        [UIView animateWithDuration:0.25 delay:0.1 options:UIViewAnimationOptionCurveLinear
                         animations:^
                             newmessageBannerView.frame = CGRectMake(0, 0, self.view.frame.size.width, BANNER_HEIGHT);
                         
                         completion:^(BOOL finished) 
                             [UIView animateWithDuration:0.25 delay:2.0 options:UIViewAnimationOptionCurveLinear
                                              animations:^
                                                  newmessageBannerView.frame = CGRectMake(0, -BANNER_HEIGHT, self.view.frame.size.width, BANNER_HEIGHT);
                                              completion:^(BOOL finished) 
                                                  [newmessageBannerView removeFromSuperview];
                                                  showingNotification = NO;
                                              ];
                         ];
    

我尝试测试 ios 6.0、7.04、7.1。
