iOS项目中开发过程中如果有代码规范，每次新增文件都会必须添加需要的代码，因此需要对文件的代码模板重新按照项目的要求修改.

Xcode系统模板的路径是/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/Xcode/Templates/，文件夹里面有文件模板File Templates和工程模板Project Templates，如果修改UIViewController模板路径如下:

选择UIViewController文件夹下的模板文件:

FlyElephant.png

代码自定义模板:
<pre><code>`//
// FILENAME
// PROJECTNAME
//
// Created by FULLUSERNAME on DATE.
//COPYRIGHT
//

import "FILEBASENAME.h"

@interface FILEBASENAMEASIDENTIFIER ()

@end

@implementation FILEBASENAMEASIDENTIFIER

pragma mark - LifeCycle

• (void)viewDidLoad {
  [super viewDidLoad];
  // Do any additional setup after loading the view.
  }

• (void)viewWillAppear:(BOOL)animated {
  [super viewWillAppear:animated];
  }

• (void)viewDidAppear:(BOOL)animated {
  [super viewDidAppear:animated];
  }

• (void)viewWillDisappear:(BOOL)animated {
  [super viewWillDisappear:animated];
  }

• (void)didReceiveMemoryWarning {
  [super didReceiveMemoryWarning];
  // Dispose of any resources that can be recreated.
  }

pragma mark - Public

pragma mark - Private

pragma mark - Accessors

pragma mark - Request

@end
`</code></pre>

新建控制器:

创建完成之后模板:
<pre><code>`//
// FEViewController.m
// DynamicDemo
//
// Created by keso on 2017/4/22.
// Copyright © 2017年 FlyElephant. All rights reserved.
//

import "FEViewController.h"

@interface FEViewController ()

@end

@implementation FEViewController

pragma mark - LifeCycle

• (void)viewDidLoad {
  [super viewDidLoad];
  // Do any additional setup after loading the view.
  }

• (void)viewWillAppear:(BOOL)animated {
  [super viewWillAppear:animated];
  }

• (void)viewDidAppear:(BOOL)animated {
  [super viewDidAppear:animated];
  }

• (void)viewWillDisappear:(BOOL)animated {
  [super viewWillDisappear:animated];
  }

• (void)didReceiveMemoryWarning {
  [super didReceiveMemoryWarning];
  // Dispose of any resources that can be recreated.
  }

pragma mark - Public

pragma mark - Private

pragma mark - Accessors

pragma mark - Request

@end
`</code></pre>

同时可以自定义设置模板,在文件模板下新建自定义文件夹，然后将Cocoa Touch Class.xctemplate拷贝进入新建文件下:
