进程通信，第三次发送消息的时候就会进入安全模式，求解

FF1990 · 2014 年12 月 31 日 10:02

接收消息的是一个Tweak
代码如下：

-(void)applicationDidFinishLaunching:(id)applicationDidFinishLaunching
{
    %orig;
    CPDistributedMessagingCenter *server = [CPDistributedMessagingCenter centerNamed:@"com.FF_IOS.server"];
    
    rocketbootstrap_distributedmessagingcenter_apply(server);
    
    [server registerForMessageName:@"msgTest" target:self selector:@selector(handleMessageNamed:userInfo:)];
    [server runServerOnCurrentThread];
    
    NSLog(@"FFFFFFFFFFFFFFFF  serverInit  FFFFFFFFFFFFFFFFFFFFF");
    
    UIAlertView *alertView=[UIAlertView alloc] initWithTitle:@"ServerInit" message:nil delegate:nil cancelButtonTitle:@"ok" otherButtonTitles:nil];
    [alertView show];
    [alertView release];
}

%new(v@:@@)
- (void) handleMessageNamed:(NSString *)name userInfo :(NSDictionary *)userInfo
{
    
    if([name isEqualToString: @"msgTest"])
    {
        NSLog(@"FFFFFFFFFFFFFFFF  receiveSomething    FFFFFFFFFFFFFFFFFFFFF");
        
        UIAlertView *alertView=[UIAlertView alloc] initWithTitle:@"message" message:@"receive a Msg!" delegate:nil cancelButtonTitle:@"ok" otherButtonTitles:nil];
        [alertView show];
        [alertView release];
    }
}

发送消息的是一个ActivatorListener，发送代码是这样的：

CPDistributedMessagingCenter *c = [CPDistributedMessagingCenter centerNamed:@"com.FF_IOS.server"];
        rocketbootstrap_distributedmessagingcenter_apply(c);
        
        [c sendMessageName:@"msgTest" userInfo:nil];
        [c release];

发送消息都能接收到，alert会弹出，然后第三次就会进入安全模式，试过好几遍了，请问一下这问题出在哪呢

看syslog里面有没有什么错误信息

FF1990 · 2014 年12 月 31 日 16:33

好的，下回会注意
输出有点点，第一条第二条是正常打印，然后就进入安全模式了
syslog信息如下

这个是错误信息，应该是空指针、野指针的问题。你的所有代码就是这些了吗？

snakeninny · 2015 年1 月 3 日 15:13

[c release];

这里不应该release吧？
