美图秀秀首页界面设计（一）

　　本文设计了美图秀秀官方版的界面，从中可以学到自定义View，自动布局，启动界面设置。代码有点凌乱，我在一步步改善。【声明：本博客只能用作学习用途，不得用于商业用途，图片资源均来自官方，产生纠纷，本人不负责】

项目中的图片资源均来自官方版的下载包中的图片（原始图片），这样我们可以通过模仿成功案例来学习iOS开发。[刚更新了项目下载地址，如需下载请滑到最下面点击项目下载.关于屏幕适配已更新]

　　项目结构及介绍

category组中存放对类的扩展

Utiles中存放一些常用的代码

controller中存放viewController文件

network存放访问网络的工具类

3rd lib存放项目中使用到的第三方类库

views存放自定义视图

models存放数据类

images存放项目中的图片资源

　　应用程序图标设置

使用XCODE打开Images.xcassets文件，编辑AppIcon，如下图

具体图标要求请参见苹果官方文档

这样我们就设置了应用程序在桌面中的显示图标

　　启动界面设置

　　1.使用XCODE打开Images.xcassets文件，编辑LaunchImage，拖放具体图片资源。具体图标要求请参见苹果官方文档

　　2.修改AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {// Override point for customization after application launch.[NSThread sleepForTimeInterval:10.0];//    [application setStatusBarHidden:YES withAnimation:UIStatusBarAnimationFade];return YES;
}

在 application: didFinishLaunchingWithOptions:方法中添加

[NSThread sleepForTimeInterval:10.0];

10.0说明启动界面将持续10秒，一般我们设置为3.0就ok。可以根据你的需求来设置启动界面的时常。

　　首页界面设计

我将首页拆分为几个独立的视图，分别为

图一为简单的UIImageView对象，图二为自定义视图。图三为UIScrollView对象中包含8个自定义按钮，图四为简单的button，图五为简单的pageControl,图六为简单的button。适应多种分辨率。下面是Autolayout实现

 [self.view addConstraints:@[[NSLayoutConstraint constraintWithItem:self.topView attribute:NSLayoutAttributeTop relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeTop multiplier:1.0 constant:0],[NSLayoutConstraint constraintWithItem:self.topView attribute:NSLayoutAttributeRight relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeRight multiplier:1.0 constant:-6],[NSLayoutConstraint constraintWithItem:self.topView attribute:NSLayoutAttributeWidth relatedBy:NSLayoutRelationEqual toItem:nil attribute:NSLayoutAttributeNotAnAttribute multiplier:1.0 constant:51],[NSLayoutConstraint constraintWithItem:self.topView attribute:NSLayoutAttributeHeight relatedBy:NSLayoutRelationEqual toItem:nil attribute:NSLayoutAttributeNotAnAttribute multiplier:1.0 constant:61],[NSLayoutConstraint constraintWithItem:btnSetting attribute:NSLayoutAttributeBottom relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeBottom multiplier:1.0 constant:-8],[NSLayoutConstraint constraintWithItem:btnSetting attribute:NSLayoutAttributeRight relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeRight multiplier:1.0 constant:-6],[NSLayoutConstraint constraintWithItem:btnSetting attribute:NSLayoutAttributeWidth relatedBy:NSLayoutRelationEqual toItem:nil attribute:NSLayoutAttributeNotAnAttribute multiplier:1.0 constant:39],[NSLayoutConstraint constraintWithItem:btnSetting attribute:NSLayoutAttributeHeight relatedBy:NSLayoutRelationEqual toItem:btnSetting attribute:NSLayoutAttributeWidth multiplier:1.0 constant:0],[NSLayoutConstraint constraintWithItem:self.scrolleView attribute:NSLayoutAttributeTop relatedBy:NSLayoutRelationEqual toItem:image attribute:NSLayoutAttributeBottom multiplier:1.0 constant:0],[NSLayoutConstraint constraintWithItem:self.scrolleView attribute:NSLayoutAttributeLeft relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeLeft multiplier:1.0 constant:0],[NSLayoutConstraint constraintWithItem:self.scrolleView attribute:NSLayoutAttributeWidth relatedBy:NSLayoutRelationEqual toItem:nil attribute:NSLayoutAttributeNotAnAttribute multiplier:1.0 constant:WIDTH],[NSLayoutConstraint constraintWithItem:self.scrolleView attribute:NSLayoutAttributeHeight relatedBy:NSLayoutRelationEqual toItem:nil attribute:NSLayoutAttributeNotAnAttribute multiplier:1.0 constant:HEIGHT - 47 - 61]]];

按钮的分页显示实现

    for (int i = 0; i < 8; i++) {NSInteger row  = i % 2;NSInteger col  = i / 2;NSInteger page = i / 6;if (col == 3) {col = 0;}btnHome = [FWButton buttonWithType:UIButtonTypeCustom];[btnHome setTitle:[textArr objectAtIndex:i] forState:UIControlStateNormal];[btnHome setImage:[UIImage imageNamed:[imageViewImageArr objectAtIndex:i]] forState:UIControlStateNormal];[btnHome setBackgroundColor:[UIColor colorWithPatternImage:[UIImage imageNamed:[imageViewBackImageArr objectAtIndex:i]]]];[btnHome setBackgroundColorHighlighted:[UIColor colorWithPatternImage:[UIImage imageNamed:[highLightedBackImageArr objectAtIndex:i]]]];
//        btnHome.frame =CGRectMake([(NSString *)[xArr objectAtIndex:i] floatValue], [(NSString *)[yArr objectAtIndex:i] floatValue], kWidth, kheight);btnHome.frame = CGRectMake(row * (kWidth + kPadding) + page * WIDTH + startX, col * (kHeight + kPadding) + startY, kWidth, kHeight);[btnHome.titleLabel setFont:[UIFont systemFontOfSize:14]];[btnHome addTarget:self action:@selector(btnClicked:) forControlEvents:UIControlEventTouchUpInside];btnHome.topPading = 0.5;[self.scrolleView addSubview:btnHome];self.scrolleView.contentSize = CGSizeMake(WIDTH * 2, kHeight * 3 + kPadding * 2);}
