在可可Mac上創建新窗口的問題點擊按鈕

我有兩個類，firstView & secondView。在firstView.h在可可Mac上創建新窗口的問題點擊按鈕

 
#import "SecondView.h" 
#import "FirstView" 


@interface FirstView : NSObject { 

    IBOutlet NSButton *test; 
    secondView *mySecond; 
} 

@property (nonatomic, retain) IBOutlet NSButton *test; 


-(IBAction) buttonClicked:(id)sender; 

@end

在firstView.m

 
#import "FirstView.h" 


@implementation FirstView 
@synthesize test; 


-(IBAction) buttonClicked:(id)sender{ 

    NSLog(@"HELLO!!!"); 
    if (!mySecond) { 
     // If the second view controller doesn't exist yet, make it! 
     mySecond = [[secondView alloc] init]; 
    } 
    [mySecond displayWindow]; 
} 

@end

在secondView.h

 
#import 


@interface SecondView : NSObject { 

    IBOutlet NSWindow *progressWindow; 
    IBOutlet NSButton *testNew; 
} 

@property (nonatomic, retain) IBOutlet NSButton *testNew; 

- (void)displayWindow; 

-(IBAction) buttonClickedNew:(id)sender; 

@end

在secondView.m

 
#import "SecondView.h" 


@implementation SecondView 
@synthesize testNew; 

- (id)init { 

    if (self = [super init]) { 
     NSLog(@"HAI!!"); 

     [NSBundle loadNibNamed:@"Next" owner:self]; 
    } 
    return self; 

} 

- (void)displayWindow { 

    if (![progressWindow isVisible]) { 
     NSLog(@"ON SECOND!!!"); 
     [progressWindow setIsVisible:YES]; 
     [progressWindow orderFront:nil];   
    } 

} 

-(IBAction) buttonClickedNew:(id)sender { 

    NSLog(@"GOOD!!!"); 
} 

@end

但我得到的輸出爲...

有一個控制可可中的窗口的類：NSWindowController你爲什麼不使用它？通過子類化NSWindowController可以獲得所有的細節，然後你只需要添加特定於你的用例的方法。簡單得多。

此外，還不清楚這些是單獨的窗口還是單獨的視圖。如果後者，你想調查NSViewController
