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”。唯一不被调用的功能是handleMessageNamed:withUserInfo函数:
为什么这不起作用？
谢谢!
最佳答案
尝试darwin通知https://developer.apple.com/library/mac/documentation/corefoundation/Reference/CFNotificationCenterRef/Reference/reference.html这是一个 public API，应该很容易找到示例代码。
