【11/02】 iOS开发成长之路，【控件初始化方法封】

封装控件的初始化方法

在平时的工作中，养成良好的编码习惯，命名风格，对以后的工作真的很重要。
总结了几点

• 尽量把重复的代码抽取出来
• 需要的传递参数拿出来
• 返回的参数

优化代码

以下是一个注册的简单界面，自己试着做了代码的重构，不断的重构才能让代码更加精简。虽然还是有很多重复的代码。但是应该比以前好点了吧。

#define DefaultHeight 44 // 每行高度#define textMarginLeft self.view.width*0.2 // 文字左边距#define iconSize 30                        // 图标尺寸 30*30#define iconMarginLeft self.view.width*0.1  // 图标左边距#define textWidth self.view.width*0.6   //  text的宽度// 输入框默认尺寸#define textFieldDefaultSize CGRectMake(textMarginLeft, i*DefaultHeight, textWidth, DefaultHeight)// 提示文本及按钮默认尺寸#define labelDefaultSize CGRectMake(0, (i)*DefaultHeight, self.view.width, DefaultHeight )@interface DSNewRegisterViewController (){    UILabel *agreeLabel;}@end@interface DSNewRegisterViewController ()@end@implementation DSNewRegisterViewController- (void)viewDidLoad {    [super viewDidLoad];
