[英]CPDistributedMessagingCenter not working ios7
我对越狱的iOS开发相当陌生,并且有一个问题。 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! 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
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];
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”。 唯一没有被调用的就是handleMessageNamed:withUserInfo函数:
为什么这不起作用?
谢谢!
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:
进程间通讯
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; 您会在Xcode控制台中拒绝查找。
解决方法 :
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。”
