如何处理UIApplication handleOpenURL有很多回报？

Question

我在AppDelegate中遇到问题

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation

许多库必须在此函数中为其配置添加一些返回代码。像这样：

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
//facebook
 //attempt to extract a token from the url
    return [FBAppCall handleOpenURL:url
                  sourceApplication:sourceApplication
                    fallbackHandler:^(FBAppCall *call) {
                        NSLog(@"In fallback handler");
                    }];

//library
BOOL urlHasBeenHandledByDispatcher = [[GRKConnectorsDispatcher sharedInstance] dispatchURLToConnectingServiceConnector:url];
if ( urlHasBeenHandledByDispatcher  ) return YES;
return NO;

//facebookSession
return [FBSession.activeSession handleOpenURL:url];
}

如何在这种情况下配置以使所有库工作？

您应该只更改一次代码并返回值。请尝试以下代码：

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
//facebook
 //attempt to extract a token from the url
    BOOL result = NO;
    result |= [FBAppCall handleOpenURL:url
                  sourceApplication:sourceApplication
                    fallbackHandler:^(FBAppCall *call) {
                        NSLog(@"In fallback handler");
                    }];

//library
result |= [[GRKConnectorsDispatcher sharedInstance] dispatchURLToConnectingServiceConnector:url];
//facebookSession
result |= [FBSession.activeSession handleOpenURL:url];
return result;
}

如果至少有一个库返回YES，则此方法将返回YES，否则返回NO。
