我正在为 iPad 开发 iOS 应用程序。我将推送通知与名为 HelpShift 的服务一起使用。当用户点击通知时，我想运行一段代码。当应用程序处于活动状态时，它实际上可以工作，但是当它处于后台或非活动状态时，它就不起作用了。这是我的代码：
- (void) application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
if ([[userInfo objectForKey:@"origin"] isEqualToString:@"helpshift"]) {
UIApplicationState state = [application applicationState];
if (state == UIApplicationStateActive) {
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"You were answered in HelpShift"
message:@"Hello"
delegate:self
cancelButtonTitle:@"Cancel"
otherButtonTitles:@"Show", nil];
[alertView show];
} if (state== UIApplicationStateBackground) {
UIViewController *vc = self.window.rootViewController;
[[Helpshift sharedInstance] handleNotification:userInfo withController:vc];
[self showHelpShift];
} if (state == UIApplicationStateInactive) {
UIViewController *viewController =
[[UIStoryboard storyboardWithName:@"MainStoryboard"
bundle:NULL] instantiateViewControllerWithIdentifier:@"home"];
[[Helpshift sharedInstance] handleNotification:userInfo withController:viewController];
}
}
}
- (void) showHelpShift {
UIViewController *vc = self.window.rootViewController;
[[Helpshift sharedInstance] showSupport:vc];
}
- (void)alertView:(UIAlertView *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex{
if (buttonIndex == 1){
UIViewController *vc = self.window.rootViewController;
[[Helpshift sharedInstance] showSupport:vc];}
}
如您所见，问题在于 [self showHelpShift] 没有被调用或被提前调用。
