Question

例如：

-(void) myExample { 
    ..do something 
} 

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

Answer 1

如果這兩種方法都在同一級別比你可以直接打電話從第二種方法第一種方法如下：

-(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

當你調用myOther，通過自我引用。你應該像這樣定義C方法：

void myOther(id callBack) 

現在你在c函數中有自引用。

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