ios9Tips

ios9变化挺多的，一哥们写的挺好，贴上地址。

https://github.com/ChenYilong/iOS9AdaptationTips

一、ios9网络适配_ATS(App Transport Security):改用更安全的HTTPS

一个符合 ATS 要求的 HTTPS，应该满足如下条件：

1、Transport Layer Security协议版本要求TLS1.2以上

2、服务的Ciphers配置要求支持Forward Secrecy等

3、证书签名算法符合ATS要求等

解决方案

方案一：立即让公司的服务端升级使用TLS 1.2，以解析相关数据

方案二：虽Apple不建议，但可通过在 Info.plist 中声明，倒退回不安全的网络请求依然能让App访问指定http，甚至任意的http

让ios9支持http的最暴力的方法：

在info.plist中设置:NSAppTransportSecurity( 类型Dictionary)->Allow Arbitrary Loads(类型Boolean):YES

在OS X EI Capitan系统的终端中通过nscurl命令来诊断检查你的HTTPS服务配置是否满足Apple的ATS要求:

$ nscurl --verbose --ats-diagnostics https://<your_server_domain>[/code] 
二、iOS9新特性:更灵活的后台定位

三、企业级分发

*有两处变化：

1、iOS9以后，企业级分发ipa包将遭到与Mac上dmg安装包一样的待遇：默认不能安装，也不再出现“信任按钮”

2、iOS9以后，企业分发时可能存在：下载的ipa包与网页两者的 bundle ID 无法匹配而导致下载失败的情况*

iOS9以后，企业级分发ipa包将遭到与Mac上dmg安装包一样的待遇：默认不能安装，也不再出现“信任按钮”

iOS9以后，企业分发时可能存在：下载的ipa包与网页两者的 bundle ID 无法匹配而导致下载失败的情况

企业APP安装之后，在网络情况为Wi-Fi环境的时候，可能会出现无法验证应用的情况。而此时，Wi-Fi网络是接入互联网的。如果多次验证不通过的话，我们需要切换到非Wi-Fi网络环境下才能解决这个问题

Q-A

Q：企业分发，企业版证书在iOS9上安装应用报 Ignore manifest download, already have bundleID: com.mycom.MyApp 只有我的手机无法安装，别人 iOS9 都可以安装

A：这并非 iOS9的问题，iOS8及以前的系统也会出现，和缓存有关系，请尝试关机重启手机，然后就可以安装了

四、ios9 URL Scheme适配_引入白名单概念

在iOS9中，如果使用 canOpenURL: 方法，该方法所涉及到的 URL scheme 必须在”Info.plist”中将它们列为白名单，否则不能使用。key叫做LSApplicationQueriesSchemes ，键值内容是

LSApplicationQueriesSchemes

urlscheme

urlscheme2

urlscheme3

urlscheme4

白名单上限是50个：

五、搜索API

分为两类首先都要导入CoreSpotlight.framework、MobileCoreServies.framework.

第一种：

#import <CoreSpotlight/CoreSpotlight.h>
#import <MobileCoreServices/MobileCoreServices.h>

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
[super viewDidLoad];
[self uiConfig];
[self spotLightIndexing];
}

- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
}

-(void)uiConfig{
self.view.backgroundColor=[UIColor whiteColor];
self.title=@"ios9ApiDemo";
}

-(void)spotLightIndexing{
NSString *path=[[NSBundle mainBundle] pathForResource:@"data" ofType:@"plist"];
NSArray *plistArr=[[NSArray alloc] initWithContentsOfFile:path];

[plistArr enumerateObjectsUsingBlock:^(NSDictionary *  _Nonnull dict, NSUInteger idx, BOOL * _Nonnull stop) {
CSSearchableItemAttributeSet *attributeSet = [[CSSearchableItemAttributeSet alloc] initWithItemContentType:(NSString *)kUTTypeImage];

// Set properties that describe attributes of the item such as title, description, and image.
NSString *title = [dict objectForKey:@"title"];
attributeSet.title = title;
attributeSet.contentDescription = [NSString stringWithFormat:@"%@，天空是什么颜色,听阴天说什么",title];
attributeSet.keywords = @[title];

// Create an attribute set for an item
UIImage *image = [UIImage imageNamed:[dict objectForKey:@"image_name"]];
NSData *imageData = [NSData dataWithData:UIImagePNGRepresentation(image)];
attributeSet.thumbnailData = imageData;

// Create a searchable item, specifying its ID, associated domain, and the attribute set you created earlier.
CSSearchableItem *item;
NSString *identifier = [NSString stringWithFormat:@"%@",attributeSet.title];
item = [[CSSearchableItem alloc] initWithUniqueIdentifier:identifier domainIdentifier:@"what's up" attributeSet:attributeSet];

// Index the item.
[[CSSearchableIndex defaultSearchableIndex] indexSearchableItems:@[item] completionHandler: ^(NSError * __nullable error) {
if (error) {
NSLog(@"error=%@",error.localizedDescription);
}
}];
}];
}

六、iOS国际化问题：当前设备语言字符串返回有变化

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSArray *allLanguage = [defaults objectForKey:@"AppleLanguages"];
NSString *currentLanguage = [allLanguage objectAtIndex:0];
NSLog(@"The current language is : %@", currentLanguage);

iOS 9 之前：以上返回结果：语言字符串代码。例如："zh-Hans"

iOS 9:以上返回结果：语言字符串代码 + 地区代码。例如："zh-Hans-US"
