开发的过程当中，有些时候会用到手机系统或者App本身的一些信息。例如：手机型号、手机系统版本等。下面是常用的获取方法：
获取手机型号
+ (NSString *)iphoneType{
struct utsname systemInfo;
uname(&systemInfo);
NSString *platform = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];
//iPhone
if ([platform isEqualToString:@"iPhone1,1"]) return @"iPhone 1G";
...
//其他对应关系请看下面对应表
return platform;
}
iPhone设备类型与通用手机类型一一对应关系表
设备类型 通用类型
iPhone1,1 iPhone 1G
iPhone1,2 iPhone 3G
iPhone2,1 iPhone 3GS
iPhone3,1 iPhone 4
iPhone3,2 iPhone 4
iPhone4,1 iPhone 4S
iPhone5,1 iPhone 5
iPhone5,2 iPhone 5
iPhone5,3 iPhone 5C
iPhone5,4 iPhone 5C
iPhone6,1 iPhone 5S
iPhone6,2 iPhone 5S
iPhone7,1 iPhone 6 Plus
iPhone7,2 iPhone 6
iPhone8,1 iPhone 6S
iPhone8,2 iPhone 6S Plus
iPhone8,4 iPhone SE
iPhone9,1 iPhone 7
iPhone9,3 iPhone 7
iPhone9,2 iPhone 7 Plus
iPhone9,4 iPhone 7 Plus
iPhone10,1 iPhone 8
iPhone10.4 iPhone 8
iPhone10,2 iPhone 8 Plus
iPhone10,5 iPhone 8 Plus
iPhone10,3 iPhone X
iPhone10,6 iPhone X
iPhone11,8 iPhone XR
iPhone11,2 iPhone XS
iPhone11,4 iPhone XS Max
Phone11,6 iPhone XS Max
获取手机系统版本
NSString *phoneVersion = [[UIDevice currentDevice] systemVersion];
获取App BundleId
NSString *bundleId = [[NSBundle mainBundle] bundleIdentifier];
获取App 版本号
NSString *bundleVersionCode = [[[NSBundle mainBundle]infoDictionary] objectForKey:@"CFBundleVersion"];
权限信息查看
应用程序在iOS系统下，如果想要获取隐私权限的话，需要征得用户的同意。最常见的就是给出权限提醒，用户给出权限，应用即可使用，但是如果用户拒绝，则相应的功能就受限了。但是有的时候我们要用到一个功能的时候，需要首先判断用户是否同意了程序使用相关权限。系统的权限种类有很多。例如：网络权限，相机权限，麦克风权限，相册权限，地理位置，日历，联系人，蓝牙等。下面举几个常见的判断手机权限的例子：
/*
*相册权限
*/
- (void)permissionTypePhotoAction{
PHAuthorizationStatus photoStatus = [PHPhotoLibrary authorizationStatus];
__block LGJPermissionManager *weakSelf = self;
if (photoStatus == PHAuthorizationStatusNotDetermined) {

if (status == PHAuthorizationStatusAuthorized) {
weakSelf.block(YES, @(photoStatus));
} else {
weakSelf.block(NO, @(photoStatus));
}
}];
} else if (photoStatus == PHAuthorizationStatusAuthorized) {
self.block(YES, @(photoStatus));
} else if(photoStatus == PHAuthorizationStatusRestricted||photoStatus == PHAuthorizationStatusDenied){
self.block(NO, @(photoStatus));
[self pushSetting:@"相册权限"];
}else{
self.block(NO, @(photoStatus));
}
}
/*
*相机权限
*/
- (void)permissionTypeCameraAction{
AVAuthorizationStatus authStatus = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo];
__block LGJPermissionManager *weakSelf = self;
if(authStatus == AVAuthorizationStatusNotDetermined){
[AVCaptureDevice requestAccessForMediaType:AVMediaTypeVideo completionHandler:^(BOOL granted) {
weakSelf.block(granted, @(authStatus));
}];
} else if (authStatus == AVAuthorizationStatusAuthorized) {

} else if(authStatus == AVAuthorizationStatusRestricted||authStatus == AVAuthorizationStatusDenied){
self.block(NO, @(authStatus));
[self pushSetting:@"相机权限"];
}else{
self.block(NO, @(authStatus));
}
}
/*

AVAudioSessionRecordPermission micPermisson = [[AVAudioSession sharedInstance] recordPermission];
__block LGJPermissionManager *weakSelf = self;

分享功能
利用UIActivityViewController类可以轻松实现分享功能
系统文件分享
以下是实现代码：
- (IBAction)click:(UIButton *)sender {
NSURL *url = [NSURL fileURLWithPath:@"/Users/adiqueen/Desktop/LGJDemo/LGJDemo/[Android开发从入门到精通].扶松柏.扫描版.pdf"];
NSArray *objectsToShare = @[url];
UIActivityViewController *controller = [[UIActivityViewController alloc] initWithActivityItems:objectsToShare applicationActivities:nil];
NSArray *excludedActivities = @[UIActivityTypePostToTwitter, UIActivityTypePostToFacebook,
UIActivityTypePostToWeibo,
UIActivityTypeMessage, UIActivityTypeMail,
UIActivityTypePrint, UIActivityTypeCopyToPasteboard,
UIActivityTypeAssignToContact, UIActivityTypeSaveToCameraRoll,
UIActivityTypeAddToReadingList, UIActivityTypePostToFlickr,
UIActivityTypePostToVimeo, UIActivityTypePostToTencentWeibo];
controller.excludedActivityTypes = excludedActivities;
[self presentViewController:controller animated:YES completion:nil];
}
