auto Layout
1, 以iPhone5s为根基的代码自动布局后续版本全适配.
扩展链接(关于iPhone的各版本像素点以及iOS8,Xcode6的一些描述):

(1)引入数据
iPhone4s 480/320 ——— 1.5
iPhone5s 568/320 ———1.775
iPhone6 667/375 ——— 1.779
iPhone6plus 736/414 ———1.778
观察可以发现规律,排除iPhone4s ,后续的iPhone版本高宽比例大致都处在1.77 - 1.78这个范围.(就目前而言).于是就产生了以iPhone5s为根基的代码自动布局后续版本全适配.
(2)关键代码段
AppDelegate.h
1 #import <UIKit/UIKit.h>
2
3 @interface AppDelegate : UIResponder <UIApplicationDelegate>
4
5 @property (strong, nonatomic) UIWindow *window;
6
7 @property float autoSizeScaleX;
8 @property float autoSizeScaleY;
9
10 + (void)storyBoradAutoLay:(UIView *)allView;
11 @end
1 #define ScreenHeight ([[UIScreen mainScreen] bounds].size.height)
2
3 #define ScreenWidth ([[UIScreen mainScreen] bounds].size.width)
4
5 #import "AppDelegate.h"
6
7 @interface AppDelegate ()
8
9 @end
10
11 @implementation AppDelegate
12 //此处的类方法实现需要注意,如果当前的view层次结构比较复杂,则应该多嵌套几次循环
13 + (void)storyBoradAutoLay:(UIView *)allView
14 {
15 for (UIView *temp in allView.subviews) {
16 temp.frame = CGRectMake1(temp.frame.origin.x, temp.frame.origin.y, temp.frame.size.width, temp.frame.size.height);
17 for (UIView *temp1 in temp.subviews) {
18 temp1.frame = CGRectMake1(temp1.frame.origin.x, temp1.frame.origin.y, temp1.frame.size.width, temp1.frame.size.height);
19 }
20 }
21 }
22
23 CG_INLINE CGRect
24 CGRectMake1(CGFloat x, CGFloat y, CGFloat width, CGFloat height)
25 {
26 AppDelegate *myDelegate = [[UIApplication sharedApplication] delegate];
27 CGRect rect;
28 rect.origin.x = x * myDelegate.autoSizeScaleX; rect.origin.y = y * myDelegate.autoSizeScaleY;
29 rect.size.width = width * myDelegate.autoSizeScaleX; rect.size.height = height * myDelegate.autoSizeScaleY;
30 return rect;
31 }
32
33 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
34 // Override point for customization after application launch.
35
36 AppDelegate *myDelegate = [[UIApplication sharedApplication] delegate];
37
38 myDelegate.autoSizeScaleX = ScreenWidth/320;
39 myDelegate.autoSizeScaleY = ScreenHeight/568;
40
41
42 return YES;
43 }(3)使用时只要在有需求的.m文件导入Appdelegate.h,引用storyBoradAutoLay:类方法即可
[AppDelegate storyBoradAutoLay:self.view];
