I have Three20 in my app which supports iOS 3.0 and above.
When I run the app with iOS 3.0, iOS 3.1, the app crashes right away when launching.
Below is my crash report:
Date/Time: 2012-06-26 10:38:36.761 -0600

Dyld Error Message:

Do you know what is going on,
Am I missing something in the build settings?
UPDATE 1:
So I do a search for UIApplicationDidEnterBackgroundNotification
in my project, and there are 3 results found in TTBaseNavigator.m file.
one in this segment
#ifdef __IPHONE_4_0
UIKIT_EXTERN NSString *const UIApplicationDidEnterBackgroundNotification
__attribute__((weak_import));
UIKIT_EXTERN NSString *const UIApplicationWillEnterForegroundNotification
__attribute__((weak_import));
#endif
and two in this method
- (id)init {
self = [super init];
if (self) {
_URLMap = [[TTURLMap alloc] init];
_persistenceMode = TTNavigatorPersistenceModeNone;
NSNotificationCenter* center = [NSNotificationCenter defaultCenter];
[center addObserver:self
selector:@selector(applicationWillLeaveForeground:)
name:UIApplicationWillTerminateNotification
object:nil];
#ifdef __IPHONE_4_0
if (nil != &UIApplicationDidEnterBackgroundNotification) {
[center addObserver:self
selector:@selector(applicationWillLeaveForeground:)
name:UIApplicationDidEnterBackgroundNotification
object:nil];
}
#endif
}
return self;
}
Do you know how to tweak these code so that the app will runs on iOS 3.0 and iOS 3.1.
UPDATE 2:
Currently I don't use TTBaseNavigator so I comment the two #ifdef __IPHONE_4_0 blocks.
This fixes my problem, but I wonder if anyone has other solution to make this work by not commenting Three20 code.
Many thanks.
I comment the two #ifdef __IPHONE_4_0 blocks. (please see update 1)
This fixes my problem.
