【中文标题】IOS 7 通过单击推送通知查看特定视图控制器【英文标题】:IOS 7 view Specific View Controller by Clicking Push Notification 【发布时间】:2014-03-06 12:21:51 【问题描述】:我为我的应用设置了推送通知,这样当我点击推送通知时,应用会转到主控件视图。但是,我想根据添加到应用程序中的内容查看特定的视图控制器。我该怎么做?
我的应用委托代码。
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeNone)];
return YES;
-(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
const char* data = [deviceToken bytes];
NSMutableString * token = [NSMutableString string];
for (int i = 0; i < [deviceToken length]; i++)
[token appendFormat:@"%02.2hhX", data[i]];
NSString *urlString = [NSString stringWithFormat:@"url"?token=%@",token];
NSURL *url = [[NSURL alloc] initWithString:urlString];
NSLog(@"token %@",urlString);
NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url];
NSLog(@"request %@ ",urlRequest);
NSData *urlData;
NSURLResponse *response;
urlData = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:&response error:nil];
NSLog(@"data %@",urlData);
// NSLog(@"token ",sendUserToken);
我的 php 推送通知脚本。
<?php
token ="my token"
$payload = '
"aps" :
"alert" :"'.$message.'",
"badge" : 1,
"sound" : "bingbong.aiff"
';
$ctx = stream_context_create();
stream_context_set_option($ctx,'ssl', 'local_cert','ck.pem');
stream_context_set_option($ctx,'ssl','passphrase', 'balpad');
$fp = stream_socket_client('ssl://gateway.sandbox.push.apple.com:2195',$err,$errstr,60,STREAM_CLIENT_CONNECT,$ctx);
if(!fp)
print "Failed to connect $err $errstrn";
return;
else
print "notifications sent!";
$devArray = array();
$devArray[] = $deviceToken;
foreach($deviceToken as $token)
$msg = chr(0) . pack("n",32) . pack("H*", str_replace(' ',' ',$token)).pack("n",strlen($payload)) . $payload;
print "sending message:" .$payload . "n";
fwrite($fp,$msg);
fclose($fp);
?>
这是我第一次使用推送通知,但我还没有找到合适的解决方案。我找到了一些建议(link1link2),但我发现它们有点令人困惑,我没有任何想法。请有人指导我如何制作这个。
【问题讨论】:
【参考方案1】:我有一个解决方案给你。请参考下面的示例代码:
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
UIApplicationState state = [application applicationState];
if (state == UIApplicationStateActive)
// Below Code Shows Message While Your Application is in Active State
NSString *cancelTitle = @"Ok";
NSString *message = [[userInfo valueForKey:@"aps"] valueForKey:@"alert"];
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"App Start"
message:message
delegate:nil
cancelButtonTitle:cancelTitle
otherButtonTitles: nil];
[alertView show];
[alertView release];
else
// Do stuff that you would do if the application was not active
// Please add your code to go to specific view controller here.

【参考方案2】:每当我们收到推送通知时,我们都会通过 ios 调用接收通知方法。
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo;
In this method base on your requirement you can navigate on any view; suppose that you want to navigate on firstviewcontroller, so code is like that:
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
// here you need to check in which view controller is right now on screen;
//1. if it is same in which you are then no problem just referesh controller;
//otherwise push to your view controller like following"
firstviewcontroller = [[firstviewcontroller alloc] initWithNibName:@"firstviewcontroller" bundle:nil];
[self.navigationController pushviewcontroller:firstviewcontroller animated:YES];
【讨论】:
【参考方案3】:好的,这样做:
在您的 .php 中添加另一个键,例如:
...
"alert" :"'.$message.'",
"badge" : 1,
"sound" : "bingbong.aiff",
"condition" : "viewController1"
...
你可以在那里写任何你想要的。这将告诉您收到推送时要显示的屏幕,它不需要是您的真实控制器的名称,只是一些条件,以便您可以不同的通知
然后像这样覆盖 didReceiveRemoteNotification:
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
UIApplicationState state = [application applicationState];
if (state == UIApplicationStateActive)
// Below Code Shows Message While Your Application is in Active State
NSString *strControllerToShow = [[userInfo valueForKey:@"aps"] valueForKey:@"condition"];;
if(condition != nil)
if([condition isEqualToString:@"viewController1"])
// create vc
// set properties
// push it on navigation stack
if([condition isEqualToString:@"viewController2"])
// create vc
// set properties
// push it on navigation stack
...
else
// Do stuff that you would do if the application was not active
// Please add your code to go to specific view controller here.
就是这样……

小心不要将太多信息放入推送中,Apple可以拒绝它:(以上是关于IOS 7 通过单击推送通知查看特定视图控制器的主要内容,如果未能解决你的问题,请参考以下文章
在 iOS 10 下使用 FCM 在前台单击推送通知后无法导航到特定的 viewController
