ios开发中获取常用的应用与设备信息

1. 获取版本号：

Version在plist文件中的key是“CFBundleShortVersionString”，和AppStore上的版本号保持一致，Build在plist中的key是“CFBundleVersion”，代表build的版本号，该值每次build之后都应该增加1。

[[[NSBundle
mainBundle]
infoDictionary]
objectForKey:@"CFBundleShortVersionString"];

[[NSBundle
mainBundle]objectForInfoDictionaryKey:@"CFBundleShortVersionString"];

[[[NSBundle
mainBundle]
infoDictionary]
objectForKey:@"CFBundleVersion"];

2.获取手机网络状态和运营商信息

导入

CoreTelephony.framework

引入头文件

#import <CoreTelephony/CTTelephonyNetworkInfo.h>  

#import <CoreTelephony/CTCarrier.h> 

2.1获取手机网络状

<strong><span style="font-size:14px;">-(void)networktype{
NSArray *subviews = [[[[UIApplication sharedApplication] valueForKey:@"statusBar"] valueForKey:@"foregroundView"]subviews];
NSNumber *dataNetworkItemView = nil;
for (id subview in subviews) {
if([subview isKindOfClass:[NSClassFromString(@"UIStatusBarDataNetworkItemView") class]]) {
dataNetworkItemView = subview;
break;
}
}
switch ([[dataNetworkItemView valueForKey:@"dataNetworkType"]integerValue]) {
case 0:
NSLog(@"No wifi or cellular");
infoLabel.text=@"无服务";
break;
case 1:
NSLog(@"2G");
infoLabel.text=@"2G";
break;
case 2:
NSLog(@"3G");
infoLabel.text=@"3G";
break;
case 3:
NSLog(@"4G");
infoLabel.text=@"4G";
break;
case 4:
NSLog(@"LTE");
infoLabel.text=@"LTE";
break;
case 5:
NSLog(@"Wifi");
infoLabel.text=@"Wifi";
break;
default:
break;
}}  </span></strong>

2.2获取运营商信息

<span style="color:#333333;">-(NSString*)getOperatorName{
CTTelephonyNetworkInfo *telephonyInfo = [[CTTelephonyNetworkInfo alloc] init];
CTCarrier *carrier = [telephonyInfo subscriberCellularProvider];
NSString *currentCountry=[carrier carrierName];
NSLog(@"[carrier isoCountryCode]==%@,[carrier allowsVOIP]=%d,[carrier mobileCountryCode=%@,[carrier mobileCountryCode]=%@",[carrier isoCountryCode],[carrier allowsVOIP],[carrier mobileCountryCode],[carrier mobileNetworkCode]);
return currentCountry;
} </span>

3 获取设备常用信息

3.1手机系统：iPhone
OS

NSString* phoneVersion = [[UIDevice currentDevice] systemVersion];
3.2手机类型：iPhone
6
+ (NSString *)iphoneType {

struct utsname systemInfo;

uname(&systemInfo);

NSString *platform = [NSString stringWithCString:systemInfo.machine encoding:NSASCIIStringEncoding];

if ([platform isEqualToString:@"iPhone1,1"]) return @"iPhone 2G";
