我正在将一张工作表加载到我的主.xib中,工作表是一个面板,我没有问题显示工作表或关闭它但是当我关闭它时,我收到一条错误消息:

2012-02-21 11:10:12.142 CollectionTest2[23277:10b] *** -
[AppController customSheetDidClose:returnCode:contextInfo:]: unrecognized selector sent to instance 0x359c00

这是我的代码:

/*Sheet Methods*/

- (void)showCustomSheet: (NSWindow *)window { 

    [NSApp beginSheet: panFilenameEditor modalForWindow: window modalDelegate: self didEndSelector: @selector(customSheetDidClose:returnCode:contextInfo:) contextInfo: nil];
}

- (IBAction)closeCustomSheet:(id)sender {

    [panFilenameEditor orderOut:self];
    [NSApp endSheet:panFilenameEditor];
}

- (void) customSheetDidClose   { 

    NSLog(@"sheet did close");
}

答案 0 :(得分:1)

showCustomSheet方法中,您告诉工作表调用应用控制器上的选择器customSheetDidClose:returnCode:contextInfo:。但是没有这样的方法。

有两种解决方案:

  • @selector(customSheetDidClose)传递给beginSheet:modalForWindow:modalDelegate:didEndSelector:contextInfo:
  • 或者将您的customSheetDidCloseMethod重命名为- (void)customSheetDidClose:(NSWindow *)sheet returnCode:(NSInteger)returnCode contextInfo:(void *)contextInfo
