Question

例如：

-(void) myExample {  
    ..do something   
}  

void myOther(){  
    how to call myExample function here  
}

Answer 1

如果两个方法都在同一个类中，则可以直接从第二个方法调用First方法，如下所示：

-(void) myExample {  
    ..do something   
}  

void myOther(){  
   call to myExample function
   [self myExample];
}

Answer 2

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

当您致电myOther时，请传递自我参考。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];
}

如何在可可中的普通void函数中调用 - （void）函数
