Swift開發必備資源薈萃

Swift作為蘋果推出的新一代程式語言，提供了更加高階的方式來幫助iOS開發者更快更簡單的編寫基於iOS應用，那麼它究竟有什麼好處呢，我們看看下面的程式碼比對。

Swift使用更簡單的語法，如下：
Objective-C


        
        
                
                
                        
                        
                                 if (myDelegate != nil) {
                        

                        
                                 if ([myDelegate respondsToSelector: @selector(scrollViewDidScroll:)]) {
                        

                        
                                 [myDelegate scrollViewDidScroll:myScrollView];
                        

                        
                                 }
                        

                        
                                 }

Swift


        
        
                
                
                        
                        
                                myDelegate?.scrollViewDidScroll?(myScrollView)

變數賦值幾乎和Javascript一樣簡單，除了不需要分號。相對於Objective-c，簡化了不少，如下：
Objective-C


        
        
                
                
                        
                        
                                NSString *myString = @"This is my string.";

Swift


        
        
                
                
                        
                        
                                var myString = "This is my string."

是不是很讓人興奮？？下面是你肯定需要的Swift開發資源，相信大家一定會喜歡，記得要加到你常用的書籤裡！
