下述函数中写入获取信息的代码- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions｛｝
获取分辨率：
CGRect rect_screen = [[UIScreen mainScreen] bounds]; CGFloat scale_screen= [[UIScreen mainScreen] scale]; CGSize size_screen = rect_screen.size; NSLog(@"rect_screen:%@",NSStringFromCGRect(rect_screen)); NSLog(@"size_screen:%@",NSStringFromCGSize(size_screen)); NSLog(@"scale_screen:%f",scale_screen); int width =(int)size_screen.width*scale_screen; int height =(int)size_screen.height*scale_screen; NSLog(@"%d",width); NSLog(@"%d",height); NSString *stringwidth = [NSString stringWithFormat:@"%d",width]; NSString *stringheight = [NSString stringWithFormat:@"%d",height];
获取IDFA：
NSString *adId = [[[ASIdentifierManager sharedManager] advertisingIdentifier] UUIDString];NSLog(@"IDFA: %@",adId);
获取手机序列号：NSString* identifierNumber = [[UIDevice currentDevice] uniqueIdentifier];NSLog(@"手机序列号: %@",identifierNumber);
注：上面一个已经被苹果禁止了。建议使用uuid，IDFA代替。获取手机别名：NSString* userPhoneName = [[UIDevice currentDevice] name];NSLog(@"手机别名: %@", userPhoneName);
获取设备名称：NSString* deviceName = [[UIDevice currentDevice] systemName];NSLog(@"设备名称: %@",deviceName );
获取手机系统版本：NSString* phoneVersion = [[UIDevice currentDevice] systemVersion];NSLog(@"手机系统版本: %@", phoneVersion);
获取当前应用名称：NSString *appCurName = [infoDictionary objectForKey:@"CFBundleDisplayName"];NSLog(@"当前应用名称：%@",appCurName);
获取当前应用软件版本：NSString *appCurVersion = [infoDictionary objectForKey:@"CFBundleShortVersionString"];NSLog(@"当前应用软件版本:%@",appCurVersion);
获取当前应用版本号码：NSString *appCurVersionNum = [infoDictionary objectForKey:@"CFBundleVersion"];NSLog(@"当前应用版本号码：%@",appCurVersionNum);
获取当前日期，时间：NSDate *currentDate = [NSDate date];//获取当前时间，日期 NSDateFormatter *dateFormatter1 = [[NSDateFormatter alloc] init]; NSDateFormatter *dateFormatter2 = [[NSDateFormatter alloc] init]; [dateFormatter1 setDateFormat:@"YYYY-MM-dd"]; [dateFormatter2 setDateFormat:@"hh:mm:ss"];NSString *dateString = [dateFormatter1 stringFromDate:currentDate];NSString *timeString = [dateFormatter2 stringFromDate:currentDate];NSLog(@"dateString:%@",dateString);NSLog(@"timeString:%@",timeString);
获取当前手机型号时需要自己写个方法，即iphoneType，调用即可：NSString* phoneModel = [UnityAppController iphoneType];NSLog(@"当前手机型号：%@",phoneModel);
iphoneType函数写成类方法，所以我调用时使用的是方法所在文件名(UnityAppController)＋方法(iphoneType)来调用。iphoneType方法如下：+ (NSString *)iphoneType { 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:@"iPhone5,2"]) 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:@"iPod1,1"]) return @"iPod Touch 1G"; if ([platform isEqualToString:@"iPod2,1"]) return @"iPod Touch 2G"; if ([platform isEqualToString:@"iPod3,1"]) return @"iPod Touch 3G"; 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:@"iPad2,2"]) return @"iPad 2"; if ([platform isEqualToString:@"iPad2,3"]) return @"iPad 2"; if ([platform isEqualToString:@"iPad2,4"]) return @"iPad 2"; if ([platform isEqualToString:@"iPad2,5"]) return @"iPad Mini 1G"; if ([platform isEqualToString:@"iPad2,6"]) return @"iPad Mini 1G"; if ([platform isEqualToString:@"iPad2,7"]) return @"iPad Mini 1G"; 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:@"iPad3,6"]) 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; }获取ip地址时与上述类似，写了一个获取ip的方法：+ (NSString *)getIPAddress { NSString *address = @"error"; struct ifaddrs *interfaces = NULL; struct ifaddrs *temp_addr = NULL; int success = 0; // retrieve the current interfaces - returns 0 on success success =getifaddrs(&interfaces); if (success == 0) { // Loop through linked list of interfaces temp_addr = interfaces; while(temp_addr != NULL) { if(temp_addr->ifa_addr->sa_family == AF_INET) { // Check if interface is en0 which is the wifi connection on the iPhone if([[NSString stringWithUTF8String:temp_addr->ifa_name] isEqualToString:@"en0"]) { // Get NSString from C String address = [NSString stringWithUTF8String:inet_ntoa(((struct sockaddr_in *)temp_addr->ifa_addr)->sin_addr)]; } } temp_addr = temp_addr->ifa_next; } } // Free memory freeifaddrs(interfaces); return address;}然后调用：NSString* ipAdress = [UnityAppController getIPAddress];NSLog(@"ipAdress:%@",ipAdress);
但是！！！这个方法获取的是局域网的ip；想要获取外网ip可以使用：－ (void)urlRequestOperation{ dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_BACKGROUND, 0), ^{ NSString *URLTmp1 = @"http://1212.ip138.com/ic.asp"; NSString *URLTmp = [URLTmp1 stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; NSData * resData = [NSData dataWithContentsOfURL:[NSURL URLWithString:URLTmp]]; dispatch_async(dispatch_get_main_queue(), ^{ if (resData) { //系统自带JSON解析 NSStringEncoding gbkEncoding = CFStringConvertEncodingToNSStringEncoding(kCFStringEncodingGB_18030_2000); //您的IP是：[122.222.122.22] 来自：上海市某某区 某某运营商 NSString *str3 = [[NSString alloc] initWithData:resData encoding:gbkEncoding]; NSLog(@"%@",str3); } }); });}但是！！！获取的字符串str3里包含了整个网页的信息，所以需要截取ip的部分。 所以获取外网ip要用：
NSError *error;NSURL *ipURL = [NSURL URLWithString:@"http://ifconfig.me/ip"];NSString *ip = [NSString stringWithContentsOfURL:ipURL encoding:NSUTF8StringEncoding error:&error];
最后最后，记得加上需要的头文件，这里提供几个：#import <UIKit/UIKit.h>#import <sys/utsname.h>#import <AdSupport/AdSupport.h>#import <ifaddrs.h>#import <arpa/inet.h>
