1. 獲取用戶當(dāng)前設(shè)備

 #pragma mark 獲得設(shè)備名稱
    device = [self iphoneType];
   
- (NSString *)iphoneType {
    
    // 需要導(dǎo)入頭文件：#import <sys/utsname.h>
    
    struct utsname systemInfo;
    
    uname(&systemInfo);
    
    NSString *platform = [NSString stringWithCString:systemInfo.machine encoding:NSASCIIStringEncoding];
    
    if ([platform isEqualToString:@"iPhone1,1"]) return @"iPhone 2G";
    
    if ([platform isEqualToString:@"iPhone1,2"]) return @"iPhone 3G";
    
    if ([platform isEqualToString:@"iPhone2,1"]) return @"iPhone 3GS";
    
    if ([platform isEqualToString:@"iPhone3,1"]) return @"iPhone 4";
    
    if ([platform isEqualToString:@"iPhone3,2"]) return @"iPhone 4";
    
    if ([platform isEqualToString:@"iPhone3,3"]) return @"iPhone 4";
    
    if ([platform isEqualToString:@"iPhone4,1"]) return @"iPhone 4S";
    
    if ([platform isEqualToString:@"iPhone5,1"]) return @"iPhone 5";

    if ([platform isEqualToString:@"iPhone5,3"]) return @"iPhone 5c";
    
    if ([platform isEqualToString:@"iPhone5,4"]) return @"iPhone 5c";
    
    if ([platform isEqualToString:@"iPhone6,1"]) return @"iPhone 5s";
    
    if ([platform isEqualToString:@"iPhone6,2"]) return @"iPhone 5s";
    
    if ([platform isEqualToString:@"iPhone7,1"]) return @"iPhone 6 Plus";
    
    if ([platform isEqualToString:@"iPhone7,2"]) return @"iPhone 6";
    
    if ([platform isEqualToString:@"iPhone8,1"]) return @"iPhone 6s";
    
    if ([platform isEqualToString:@"iPhone8,2"]) return @"iPhone 6s Plus";
    
    if ([platform isEqualToString:@"iPhone8,4"]) return @"iPhone SE";
    
    if ([platform isEqualToString:@"iPhone9,1"]) return @"iPhone 7";
    
    if ([platform isEqualToString:@"iPhone9,2"]) return @"iPhone 7 Plus";
    
    if ([platform isEqualToString:@"iPod1,1"])   return @"iPod Touch 1G";

    if ([platform isEqualToString:@"iPod4,1"])   return @"iPod Touch 4G";
    
    if ([platform isEqualToString:@"iPod5,1"])   return @"iPod Touch 5G";
    
    if ([platform isEqualToString:@"iPad1,1"])   return @"iPad 1G";
    
    if ([platform isEqualToString:@"iPad2,1"])   return @"iPad 2";

    if ([platform isEqualToString:@"iPad3,1"])   return @"iPad 3";
    
    if ([platform isEqualToString:@"iPad3,2"])   return @"iPad 3";
    
    if ([platform isEqualToString:@"iPad3,3"])   return @"iPad 3";
    
    if ([platform isEqualToString:@"iPad3,4"])   return @"iPad 4";
    
    if ([platform isEqualToString:@"iPad3,5"])   return @"iPad 4";

    if ([platform isEqualToString:@"iPad4,1"])   return @"iPad Air";
    
    if ([platform isEqualToString:@"iPad4,2"])   return @"iPad Air";
    
    if ([platform isEqualToString:@"iPad4,3"])   return @"iPad Air";
    
    if ([platform isEqualToString:@"iPad4,4"])   return @"iPad Mini 2G";
    
    if ([platform isEqualToString:@"iPad4,5"])   return @"iPad Mini 2G";
    
    if ([platform isEqualToString:@"iPad4,6"])   return @"iPad Mini 2G";
    
    if ([platform isEqualToString:@"i386"])      return @"iPhone Simulator";
    
    if ([platform isEqualToString:@"x86_64"])    return @"iPhone Simulator";
    
    return platform;
    
}

2. 獲取用戶當(dāng)前 IP

  //獲取ip
    [self urlRequestOperation];
    

#pragma mark  獲取ip
-(void)urlRequestOperation{

    // 需要導(dǎo)入頭文件：#import "AFNetworking.h"
    
    NSString *URLTmp = @"http://ip.taobao.com/service/getIpInfo.php?ip=myip";
    NSString *URLTmp1 = [URLTmp stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];  //轉(zhuǎn)碼成UTF-8  否則可能會(huì)出現(xiàn)錯(cuò)誤
    //    [URLTmp stringByAddingPercentEncodingWithAllowedCharacters:(nonnull NSCharacterSet *)]
    URLTmp = URLTmp1;
    NSURLRequest *request =
    [NSURLRequest requestWithURL:[NSURL URLWithString: URLTmp]];
    AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
    [operation setCompletionBlockWithSuccess:
     ^(AFHTTPRequestOperation *operation, id responseObject) {
         NSLog(@"Success: %@", operation.responseString);
         NSString *requestTmp = [NSString stringWithString:operation.responseString];
         NSData *resData = [[NSData alloc] initWithData:[requestTmp dataUsingEncoding:NSUTF8StringEncoding]];
         //系統(tǒng)自帶JSON解析
         NSDictionary *resultDic =
         [NSJSONSerialization JSONObjectWithData:resData options:NSJSONReadingMutableLeaves error:nil];
         NSLog(@"aaaaaaa=====%@",resultDic);
       
         locationIP =[[resultDic objectForKey:@"data"] objectForKey:@"ip"];

     } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
         NSLog(@"Failure: %@", error);
     }];
    [operation start];
}

3. 獲取用戶當(dāng)前版本號(hào)

  // 本地版本
    
    NSString *path = [[NSBundle mainBundle] bundlePath];
    NSString *finalPath = [path stringByAppendingPathComponent:@"Info.plist"];
    
    NSDictionary *plistDic = [NSDictionary dictionaryWithContentsOfFile:finalPath];
    NSLog(@"%@",plistDic);
   NSString *BenDiBanBen  =[plistDic objectForKey:@"CFBundleShortVersionString"];
    
    NSLog(@"本地 app版本  ==%@",BenDiBanBen);

4. 獲取用戶當(dāng)前在App store 的版本號(hào)

    NSString *urlStr = @"http://itunes.apple.com/lookup?id=改成自己app 的id";
    
    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    
    [manager POST:urlStr parameters:nil success:^(NSURLSessionDataTask *task, id responseObject) {
        
      
        NSArray *results = responseObject[@"results"];
        
        NSDictionary *dic = [results firstObject];
        
       NSString *AppStoreBanBen = [dic objectForKey:@"version"];
        
  
    } failure:^(NSURLSessionDataTask *task, NSError *error) {
        
    }];
