[英]CPDistributedMessagingCenter not working ios7
I am fairly new to jailbreak iOS development and had a question. 我对越狱的iOS开发相当陌生,并且有一个问题。 I am trying to send a message between two processes(MobileSafari to SpringBoard) and am having a problem, the reciever function in SpringBoard is never called!
我正在尝试在两个进程(从MobileSafari到SpringBoard)之间发送消息,并且遇到问题,从未调用SpringBoard中的接收器功能! So far in SpringBoard I have this:
到目前为止,在SpringBoard中,我有以下内容:
-(void)applicationDidFinishLaunching:(id)arg1{
%orig(arg1);
//register for notifications
CPDistributedMessagingCenter *messagingCenter = [CPDistributedMessagingCenter centerNamed:@"com.magnusdevelopment.flow"];
[messagingCenter runServerOnCurrentThread];
[messagingCenter registerForMessageName:@"updateWallpaper" target:self selector:@selector(handleMessageNamed:withUserInfo:)];
[messagingCenter registerForMessageName:@"updateScalingMode" target:self selector:@selector(handleMessageNamed:withUserInfo:)];
[messagingCenter registerForMessageName:@"downloadWallpaper" target:self selector:@selector(handleMessageNamed:withUserInfo:)];
UIAlertView *testAlert = [[UIAlertView alloc] initWithTitle:@"Yo!" message:@"registered" delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
[testAlert show];
}
}
%new
-(NSDictionary *)handleMessageNamed:(NSString *)name withUserInfo:(NSDictionary *)userInfo{
UIAlertView *testAlert = [[UIAlertView alloc] initWithTitle:@"Yo!" message:@"2" delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
[testAlert show];
if([name isEqualToString:@"updateWallpaper"]){
//get info for wallpaper
NSString *wallpaperImagePath = [userInfo objectForKey:@"WALLPAPER_PATH"];
int option = [[userInfo objectForKey:@"OPTION"] intValue];
BOOL retValue = setWallpaperImage(wallpaperImagePath, option);
//return the dictionary
NSMutableDictionary *replyDict = [[NSMutableDictionary alloc] init];
[replyDict setObject:[NSString stringWithFormat:@"%hhd",retValue] forKey:@"RETURN_VALUE"];
return replyDict;
}else if([name isEqualToString:@"updateScalingMode"]){
//get info from dictionary
int option = [[userInfo objectForKey:@"OPTION"] intValue];
NSString *scalingMode = [userInfo objectForKey:@"SCALING_MODE"];
//set wallpaper scaling mode
setWallpaperScalingMode(scalingMode,option);
}//end if
return nil;
}//end method
and when a button is pressed in MobileSafari I call this code: 当在MobileSafari中按下按钮时,我将此代码称为:
NSString *option = [NSString stringWithFormat:@"%i",wallpaperOption];
NSDictionary *infoDict = [NSDictionary dictionaryWithObjectsAndKeys: wallpaperPath, @"WALLPAPER_PATH", option, @"OPTION", nil];
CPDistributedMessagingCenter *messagingCenter = [CPDistributedMessagingCenter centerNamed:@"com.magnusdevelopment.flow"];
[messagingCenter sendMessageAndReceiveReplyName:@"downloadWallpaper" userInfo:infoDict];
UIAlertView *testAlert = [[UIAlertView alloc] initWithTitle:@"Yo!" message:@"sent" delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
[testAlert show];
I get the alert "registered" whenever SpringBoard starts up and then when I press the button I get the message "sent". 每当SpringBoard启动时,我都会收到警报“已注册”,然后当我按下按钮时,我会收到消息“已发送”。 The only thing that isn't called is the function handleMessageNamed:withUserInfo:
唯一没有被调用的就是handleMessageNamed:withUserInfo函数:
Why isn't this working? 为什么这不起作用?
Thanks! 谢谢!
If you look at this document entitled "Updating extensions for iOS 7 , it looks there are problems using CPDistributedMessagingCenter
on iOS 7, but Ryan Petrich has published a library that may help you work around them: 如果您查看标题为“更新iOS 7的扩展”的文档 ,则可能会
CPDistributedMessagingCenter
在iOS 7上使用CPDistributedMessagingCenter
存在问题,但是Ryan Petrich发布了一个库,可以帮助您解决这些问题:
Inter-process communication
进程间通讯
CPDistributedMessagingCenter, XPC and other IPC methods built on top of bootstrap registered mach services don't work;
建立在引导注册的Mach服务之上的CPDistributedMessagingCenter,XPC和其他IPC方法不起作用; you get deny lookup in the Xcode console.
您会在Xcode控制台中拒绝查找。

rpetrich has built a workaround called RocketBootstrap: "One common way processes communicate with each other on iOS and OS X is through a messaging system called mach ports. Each port is a channel that can either receive or send messages. There is a central registration system for these ports called bootstrap, where ports can be registered and accessed by a service name assigned to them. Recent versions of iOS restrict which names a process can access—MobileMail, MobileSafari and App Store apps are only allowed to access a very specific set of services that come with iOS. RocketBootstrap adds a secondary lookup service that doesn't restrict which processes can access which services."rpetrich建立了一个称为RocketBootstrap的变通方法:“进程在iOS和OS X上相互通信的一种常见方式是通过称为mach端口的消息传递系统。每个端口都是一个可以接收或发送消息的通道。有一个中央注册系统。对于这些称为引导程序的端口,可以通过为其分配的服务名称来注册和访问端口。iOS的最新版本限制了进程可以访问的名称-仅允许MobileMail,MobileSafari和App Store应用访问一组特定的iOS附带的服务。RocketBootstrap添加了辅助查找服务,该服务不限制哪些进程可以访问哪些服务。”
