iOS常用代碼塊&注釋規(guī)范
簡(jiǎn)潔快捷的代碼塊能極大地提高開(kāi)發(fā)效率
Xcode自帶的GDC代碼塊

@property (nonatomic, weak) <#Class#> *<#name#>;
copy屬性創(chuàng)建 快捷鍵:copy
/** <#copy屬性注釋#> */

UIAlertViewController創(chuàng)建
// UIAlertViewController(彈框視圖)
UIAlertController *<#alert#> = [UIAlertController alertControllerWithTitle:<#title#> message:<#message#> preferredStyle:<#UIAlertControllerStyle#>];
UIAlertAction *<#action#> = [UIAlertAction actionWithTitle:<#@"確定"#> style:<#UIAlertActionStyle#> handler:<#^(UIAlertAction * _Nonnull action)handler#>];
[alert addAction:<#action#>];
[self presentViewController:<#alert#> animated:<#(BOOL)#> completion:<#^(void)completion#>];
