在Watchkit上調用方法

昨天我參加了watchkit hackathon，在調用NSObject類的方法時遇到了一些問題，該類使用Google Maps API併發送本地通知。如果我把這個方法從我Watchkit擴展，代碼不編譯，但如果我從視圖控制器打電話，例如，一切完美在Watchkit上調用方法

#import "InterfaceController.h" 
#import "Methods.h" 

@interface InterfaceController() 

@end 


@implementation InterfaceController 

- (instancetype)initWithContext:(id)context { 
self = [super initWithContext:context]; 
if (self){ 
    // Initialize variables here. 
    // Configure interface objects here. 
    NSLog(@"%@ initWithContext", self); 

} 
return self; 
} 
- (IBAction)butRoute 
{ 
    Methods *mt = [[Methods alloc]init]; 
    [mt notif:@"ARRIVING!"]; 
    //***** If I call this method, my code won't compile!!! ***** 

} 

- (void)willActivate { 
// This method is called when watch view controller is about to be visible to user 
NSLog(@"%@ will activate", self); 
} 

- (void)didDeactivate { 
// This method is called when watch view controller is no longer visible 
NSLog(@"%@ did deactivate", self); 
} 

@end

我得到的錯誤是： Error
