iOS获取App信息、设备信息

第一部分：App的信息

获取App的版本号、App的build版本号、包名、App显示名称等等

/*获取当前App的版本号信息*/
+ (NSString *)getAppVersion
{
    NSBundle *currentBundle = [NSBundle mainBundle];
    NSDictionary *infoDictionary = [currentBundle infoDictionary];
    return [infoDictionary objectForKey:@"CFBundleShortVersionString"];
}

/*获取当前App的build版本号信息*/
+ (NSString *)getAppBuildVersion
{
    NSBundle *currentBundle = [NSBundle mainBundle];
    NSDictionary *infoDictionary = [currentBundle infoDictionary];
    return [infoDictionary objectForKey:@"CFBundleVersion"];
}

/*获取当前App的包名信息*/
+ (NSString *)getAppBundleId
{
    NSBundle *currentBundle = [NSBundle mainBundle];
    NSDictionary *infoDictionary = [currentBundle infoDictionary];
    return [infoDictionary objectForKey:@"CFBundleIdentifier"];
}

/*获取当前App的名称信息*/
+ (NSString *)getAppDisplayName
{
    NSBundle *currentBundle = [NSBundle mainBundle];
    NSDictionary *infoDictionary = [currentBundle infoDictionary];
    return [infoDictionary objectForKey:@"CFBundleDisplayName"];
}

第二部分，设备信息

手机系统版本、手机版本

/*手机系统版本*/

}


/*手机(设备)版本*/
