与NSViewController交换

Question

我正在尝试在Windows中交换两个视图。我正在使用Cocoa Framework（仅适用于Mac）和Xcode 5.1.1以及NSViewController来获取它。所有编译完美，但这不起作用， 我从编译器得到了下一条消息：

  

“libdyld.dylib 0x00007fff866995fd start + 1”

This is my Xcode Project

.h文件

#import "Cocoa/Cocoa.h"
#import "PrimaryViewController.h" //My views
#import "SecondViewController.h"

@interface
AppDelegate : NSObject <NSApplicationDelegate>
@property (assign) IBOutlet NSWindow *window;

@property (weak) IBOutlet NSView *myCustomView;
@property (strong) IBOutlet NSViewController *myViewController;

-(IBAction)button1Clicked:(id)sender;
-(IBAction)button2Clicked:(id)sender;

@end

的.m

#import "AppDelegate.h"
@implementation AppDelegate

//@synthesize myCustomView = _myCustomView;<br/>
//@synthesize myViewController = _myViewController;<br/>

-(IBAction)button1Clicked:(id)sender {
    NSLog(@"Clicked on the first button");
    [[_myViewController view ]removeFromSuperview];
    _myViewController = [[PrimaryViewController alloc] initWithNibName:@"PrimaryView­Controller" bundle:nil];
    [_myCustomView addSubview:[_myViewController view]];
    [[_myViewController view] setFrame:[_myCustomView bounds]];
}

-(IBAction)button2Clicked:(id)sender {
    NSLog(@"Clicked on the second button");
    [[_myViewController view] removeFromSuperview];
    _myViewController = [[SecondViewController alloc]initWithNibName:@"SecondaryView­Controller" bundle:nil];
    [_myCustomView addSubview:[_myViewController view]];
    [[_myViewController view]setFrame:[_myCustomView bounds]];
}

@end

请帮帮我吗？

Answer 1

在SecondaryViewController.xib中，您将文件所有者命名为SecondViewController。将其更改为SecondaryViewController，它应该可以正常工作。

Answer 2

是的，当我创建第二个“视图”时，我创建了一个文件：SecondViewController.xib，SecondViewController.h和SecondViewController.m

所以，当我创建它的实例时，在initWithNibName

中的方法“button2Clicked”

我称它为“SecondaryViewController”（vs @“SecondViewController”）。

我删除了SecondaryViewController并更改了SecondViewController，并且一切正常，感谢@TheAmateurProgrammerless;）
