    how to call myExample function here 
} 

Answer 1

如果这两种方法都在同一级别比你可以直接打电话从第二种方法第一种方法如下：

-(void) myExample { 
    ..do something

void getInputSource() { 
    TISInputSourceRef source = TISCopyCurrentKeyboardLayoutInputSource(); 
    NSLog(@"languages: %@", TISGetInputSourceProperty(source, kTISPropertyBundleID)); 
    NSLog(@"localized name: %@", TISGetInputSourceProperty(source, kTISPropertyLocalizedName)); 
    [self awakeFromNib]; 
} 

-(void) awakeFromNib { 
    self.statusBar = [[NSStatusBar systemStatusBar] statusItemWithLength:NSSquareStatusItemLength]; 
    NSImage* icon = [NSImage imageNamed:@"icon.png"]; 
    self.statusBar.image = icon; 
} 

Answer 3

当你调用myOther，通过自我引用。你应该像这样定义C方法：

void myOther(id callBack) 

现在你在c函数中有自引用。

void myOther(id callBack){ 
    [callBack myExample]; 
}
