auto Layout

1, 以iPhone5s爲根基的代碼自動佈局後續版本全適配.

擴展連接(關於iPhone的各版本像素點以及iOS8,Xcode6的一些描述):

(1)引入數據

iPhone4s      480/320 ———  1.5

 

iPhone5s      568/320  ———1.775

iPhone6        667/375  ——— 1.779

iPhone6plus  736/414  ———1.778

觀察能夠發現規律,排除iPhone4s ,後續的iPhone版本高寬比例大體都處在1.77 - 1.78這個範圍.(就目前而言).因而就產生了以iPhone5s爲根基的代碼自動佈局後續版本全適配.

(2)關鍵代碼段

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 //此處的類方法實現須要注意,若是當前的view層次結構比較複雜,則應該多嵌套幾回循環
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)使用時只要在有需求的.m文件導入Appdelegate.h,引用storyBoradAutoLay:類方法便可

    [AppDelegate storyBoradAutoLay:self.view];
