After few weeks to learn the integration between unity3d cocoa, finally found that it is not needed to modify any code from the original xCode sample project.

And the following made that happen… Oh, May I lazy forever XD
#import "UCC_Callback.h"
#import "MTJSON.h"
#import "RootViewController.h"
#import "SeismicXMLAppDelegate.h"
#define UCC_TAG 24601
void UCC_Echo(const char * bytes)
{
//----- Echo
NSString *str = [NSString stringWithUTF8String:bytes];
NSLog(@"-----> UCC_Echo:%@", str);
[UCC_Callback gameobject:@"readout" func:@"json" mms:[NSString stringWithFormat:@"{echo:%@}", str]];
}
void UCC_Remote(const char * bytes)
{
//----- for UILabel
NSString *str = [NSString stringWithUTF8String:bytes];
NSLog(@"-----> UCC_Remote:%@", str);
//----- for Unity3d
UIWindow *window = [UIApplication sharedApplication].keyWindow;
NSLog(@"-----> UCC_Remote:%@", window);
for(UIView *v in window.subviews)
{
NSLog(@"-----> UCC_Remote:%@", v);
if(v.exclusiveTouch v.multipleTouchEnabled)
{
v.exclusiveTouch = NO;
v.tag = UCC_TAG;
}
}
UIView *u3d_view = [window viewWithTag:UCC_TAG];
if(u3d_view)
{
CGRect rect = [u3d_view bounds];
UIView *ucc_view = [[UIView alloc] initWithFrame:rect];
[u3d_view addSubview:ucc_view];
NSLog(@"-----> UCC_Remote:%@", u3d_view);
//----- UIView
float w = rect.size.width;
float h = rect.size.height;
UIView *ui_view = [[UIView alloc] initWithFrame:CGRectMake(0,h/2,w,h/2)];
//----- SeismicXML
RootViewController *rootvc = [[RootViewController alloc ] init];
UINavigationController *nav = [[ UINavigationController alloc] init];
[nav pushViewController:rootvc animated:NO];
[ui_view addSubview:nav.view];
nav.view = ui_view;
SeismicXMLAppDelegate *s = [[SeismicXMLAppDelegate alloc]init];
s.window = window;
s.rootViewController = rootvc;
s.navigationController = nav;
[s applicationDidFinishLaunching:[UIApplication sharedApplication]];
//----- UILabel
CGRect rect2 = CGRectMake(w/3*2,h/16*7.5,w,h/16);
UILabel *scoreLabel = [[UILabel alloc ] initWithFrame:rect2 ];
scoreLabel.text = str;
scoreLabel.textColor = [UIColor whiteColor];
scoreLabel.backgroundColor = [UIColor blackColor];
scoreLabel.alpha = 0.75;
[[nav.view superview] insertSubview:scoreLabel aboveSubview:nav.view];
//------ Release
[scoreLabel release];
[rootvc release];
[nav release];
[ui_view release];
[ucc_view release];
}
}
For pass back the data to Unity, it’s only need 2 line of code insert to the original project.
[SeismicXMLAppDelegate.h]
#import "UCC_Callback.h"
[SeismicXMLAppDelegate.m]
- (void)addEarthquakesToList:(NSArray *)earthquakes {
// insert the earthquakes into our rootViewController's data source (for KVO purposes)
[self.rootViewController insertEarthquakes:earthquakes];
[UCC_Callback sendMessage:earthquakes]; // Yeah ! That's all XD
}
Plus, a new callback class for translate the data.
[UCC_Callback.h]
@interface UCC_Callback : NSObject
{
}
+(void)sendMessage:(NSArray *)earthquakes;
+(void)gameobject:(NSString *)gameobject func:(NSString *)func mms:(NSString *)mms;
@end
[UCC_Callback.m]
#import "UCC_Callback.h"
#import "MTJSON.h"
#import "Earthquake.h"
@implementation UCC_Callback
+(void)sendMessage:(NSArray *)earthquakes
{
Earthquake *e;
NSDictionary *dict;
NSMutableArray *json = [NSMutableArray array];
NSInteger n = [earthquakes count];
NSInteger i;
for (i = 0; i < n; i++)
{
e = [earthquakes objectAtIndex:i];
NSString *usgs_url = [e.USGSWebLink absoluteString];
NSString *location = e.location;
NSString *latitude = [NSString stringWithFormat:@"%f", e.latitude];
NSString *longitude = [NSString stringWithFormat:@"%f", e.longitude];
NSString *magnitude = [NSString stringWithFormat:@"%f", e.magnitude];
dict = [NSDictionary dictionaryWithObjectsAndKeys: usgs_url, @"usgs_url",
location, @"location",
latitude, @"latitude",
longitude, @"longitude",
magnitude, @"magnitude", nil];
[json insertObject:dict atIndex:i];
}
//----- Json
NSString *str = [NSString stringWithFormat:@"{\"feed\":%@}", [MTJSON MTJSONObjectToString:json]];
[self gameobject:@"readout" func:@"json" mms:str];
}
+(void)gameobject:(NSString *)gameobject func:(NSString *)func mms:(NSString *)mms
{
#if !(TARGET_IPHONE_SIMULATOR)
UnitySendMessage([gameobject UTF8String], [func UTF8String], [mms UTF8String]);
#endif
NSLog(@"-----> UCC_Callback:%@", mms);
}
@end
Yes, that’s all converted to JSON ! So that, I could use the same code for web deployment too ! Lazy 
Remark: I use MTJSON to do the JSON conversion, also, I made a port version for it to run inside the unity too.
