iOS-获取手机信息等常见功能整理一

作者: 见哥哥长高了 | 来源:发表于2019-06-28 08:53 被阅读0次

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) {
        
        [PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status) {
            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) {
        self.block(YES, @(authStatus));
    } else if(authStatus == AVAuthorizationStatusRestricted||authStatus == AVAuthorizationStatusDenied){
        self.block(NO, @(authStatus));
        [self pushSetting:@"相机权限"];
        
    }else{
        self.block(NO, @(authStatus));
    }
}

    if (micPermisson == AVAudioSessionRecordPermissionUndetermined) {
        [[AVAudioSession sharedInstance] requestRecordPermission:^(BOOL granted) {
            weakSelf.block(granted, @(micPermisson));
        }];
    } else if (micPermisson == AVAudioSessionRecordPermissionGranted) {
        self.block(YES, @(micPermisson));
    } else {
        self.block(NO, @(micPermisson));
        [self pushSetting:@"麦克风权限"];
    }
}


/*

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：
