iPhone与iPad在开发上的区别

1. iPhone与iPad搭载的操作系统

  • 两者都是搭载的ios操作系统.

2.屏幕的尺寸与分辨率不同

  • 1.iPhone与iPad有不同的英寸，像素和点，开发中一般只关心点坐标系
  • 2.iPhone有3.5inch，4.0inch，4.7inch，5.5inch ，分别对应的点坐标系为: 320x480,320x568,375x667，414x736
  • 3.iPad中的有9.7inch(iPad)和7.9inch(iPad mini)，对应的点坐标系都为768x1024
  • 4.其次iPad pro 12.9inch,对应的点坐标系为1024x1366
  • iPhone与iPad在开发上的区别

3.UI元素的排布和设计不同

  • 1.一般情况下iPhone应用要求只支持竖屏，iPhone游戏要求只支持横屏,iPad应用一般情况下要求既要支持横屏，也要支持竖屏
  • 2.iPad屏幕更大，他可以容纳更多的UI元素，因此排列方式与iPhone不同
  • iPhone与iPad在开发上的区别
  • iPhone与iPad在开发上的区别

4.iPhone键盘与iPad键盘

  • iPad键盘相对于iPhone键盘多了一个退出按钮，用来退出键盘
  • iPhone与iPad在开发上的区别

5.在API上的不同

  • 1. iPad有属于自己特有的API，只能用在iPad开发上
    • UIPopVerController
    • UISplitViewController
  • 2. iPhone上的API在iPad上都可以用
  • 3. iPhone上与iPad的共有的API在显示效果上有差异
    • iPhone的UIActionSheet,会从底部弹出来进行选择，并默认带取消按钮,如果相同的代码运行在iPad上会从中间弹出，并没有取消按钮

iPhone与iPad在开发上的区别

6.屏幕方向的支持不同

  • 1.iPhone上面支持3个方向，不支持HOME键朝上方向
  • 2.iPad上面支持4个方向
  • iPhone与iPad在开发上的区别

7.开发上面的细节不同

  • 1.仅仅开发iPad项目，在创建项目的时候选择iPad
  • 2.如果是需要iPhone与iPad的一起开发的时候选择universal
  • 3.仅仅开发iPhone项目，在创建项目的时候选择iPhone
  • iPhone与iPad在开发上的区别

8.设备支持应用程序的不同

  • 1.iPhone上面只能运行iPhone应用程序
  • 2.iPad上面既可以运行iPad程序，也可以运行iPhone程序
  • 3.如果在iPad运行iPhone程序会在中间显示

9.iPhone开发与iPad开发的流程

  • 开发流程都是一致的
