获得IOS系统版本号

[[[UIDevice currentDevice] systemVersion]floatValue]

获得硬件名称

+ (NSString*)getMachine{

size_t size;

sysctlbyname("hw.machine", NULL, &size, NULL,0);

char *name = malloc(size);

sysctlbyname("hw.machine",name, &size, NULL, 0);

NSString *machine = [NSStringstringWithCString:name encoding:NSUTF8StringEncoding];

free(name);

if( [machineisEqualToString:@"i386"] || [machineisEqualToString:@"x86_64"] ) machine =@"ios_Simulator";

else if( [machineisEqualToString:@"iPhone1,1"] ) machine =@"iPhone_1G";

elseif( [machineisEqualToString:@"iPhone1,2"] ) machine =@"iPhone_3G";

elseif( [machineisEqualToString:@"iPhone2,1"] ) machine =@"iPhone_3GS";

elseif( [machineisEqualToString:@"iPhone3,1"] ) machine =@"iPhone_4";

elseif( [machine isEqualToString:@"iPod1,1"]) machine = @"iPod_Touch_1G";

elseif( [machine isEqualToString:@"iPod2,1"]) machine = @"iPod_Touch_2G";

elseif( [machine isEqualToString:@"iPod3,1"]) machine = @"iPod_Touch_3G";

elseif( [machine isEqualToString:@"iPod4,1"]) machine = @"iPod_Touch_4G";

else if( [machineisEqualToString:@"iPad1,1"] ) machine =@"iPad_1";

elseif( [machine isEqualToString:@"iPad2,1"]) machine = @"iPad_2";

returnmachine;

}

IOS得到当前app 版本号

NSString *curVer = [[[NSBundle mainBundle] infoDictionary]objectForKey:@"CFBundleVersion"];
