UIDevice,设备信息

1. 判断是否是横向屏:BOOL b=UIDeviceOrientationIsLandscape([UIDevice currentDevice].orientation);

     获取设备uniqueIdentifier :[UIDevice currentDevice].uniqueIdentifier;,但在ios5中,它已被废弃。

     http://kensou.blog.51cto.com/3495587/655083

[[UIDevice currentDevice] systemName];
[[UIDevice currentDevice] systemVersion];//os version
[[UIDevice currentDevice] uniqueIdentifier];
[[UIDevice currentDevice] model];
[[UIDevice currentDevice] name];

真机上结果:
System Name: iPhone OS
System Version: 4.2.1
Unique ID: 9b5ded78d5fa0ac96250f8b4af0e46f40b96ea6d
Model: iPhone
Name: “wwk”的 iPhone

模拟器上结果:

System Name: iPhone OS
System Version: 4.2
Unique ID: 21FFE0FF-429B-5D0B-96D2-EADCA3203260
Model: iPhone Simulator
Name: iPhone Simulator

uniqueIdentifier:iPhone通过,向几个硬件标识符和设备序列号应用内部散列算法,而生成这一标识符。


2.电池事件通知及电池状态:电池水平是一个浮点值,从0.0完全放电,到1.0完全充满。

[NSLog:@"Battery level: %0.2f%", [[UIDevice currentDevice] batteryLevel] * 100];

NSArray *stateArray = [NSArray arrayWithObjects: @"Unknown", @"not plugged into a charging source", @"charging", @"full", nil];
[NSLog:@"Battery state: %@", [stateArray objectAtIndex:[[UIDevice currentDevice] batteryState]]];


获得更多设备信息:使用sysctlbyname(),sysctl()标准unix函数。

在sys/sysctl.h中提供了一些设备信息常量。要注意先要#include

具体的参考《秘籍2》14.3重新获得更多设备信息。

hw.machine的值,第一代iPhone为(iPhone1,1),iPhone3g为(iPhone1,2),iPhone3gs为(iPhone2,1),模拟器上为x86_64。


3.传感器。

  启用接近传感器后,它检测前方是否存在一个大型物体,如果有,它会关闭屏幕,并发出一般性通知。当障碍物移走后,会重新打开屏幕。这可以防止在通知过程中,误用耳朵触碰按钮。

  还要防止一些保护套会影响传感器工作。

  [UIDevice currentDevice].proximityMonitoringEnabled=YES;

  [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handleStateChange:) name:@"UIDeviceProximityStateDidChangeNotification" object:nil];    


4.加速度。

   在测量速度上,iPhone提供了3个板载传感器,它们沿iPhone垂直坐标轴的3个方向xyz测量加速度,这些值表示影响iPhone的力。

   [[UIAccelerometer sharedAccelerometer] setDelegate:self];//UIAccelerometerDelegate

   - (void)accelerometer:(UIAccelerometer *)accelerometer didAccelerate:(UIAcceleration *)acceleration
{
    float xx = -[acceleration x];
    float yy = [acceleration y];
    float angle = atan2(yy, xx);
    [arrow setTransform:CGAffineTransformMakeRotation(angle)];
}


5.检测设备方向:横线或纵向。

  [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications]; // not actually required but a good idea in case Apple changes this
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(orientationChanged:) name:UIDeviceOrientationDidChangeNotification object:nil];

//在viewController中重写shouldAutorotateToInterfaceOrientation

- (BOOL) shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation) anOrientation
{
    return (anOrientation == UIDeviceOrientationPortrait ||
    anOrientation == UIDeviceOrientationLandscapeRight ||
    anOrientation == UIDeviceOrientationLandscapeLeft ||);

   //iPhone不建议使用UIDeviceOrientationPortraitUpsizeDown

}

- (void) orientationChanged: (id) sender
{
    NSLog(@"Orientation changed to %@", [UIDevice currentDevice].orientationString);//当前设备方向
}

两个内置的宏辅助判断方向

UIDeviceOrientationIsPortrait(anOrientation)
UIDeviceOrientationIsLandscape(anOrientation)


6.摇晃检测  ShakeDetection。

  响应链:响应链提供了层级对象,一个事件若被起始处的对象接收,它不会再被向下传递;否则,继续向下传递。

  对象通常是通过[self becomeFirstResponder];声明自身为第一响应者。[self resignFirstResponder];声明退出第一响应者。第一响应者接收所有运动和触摸事件。

  - (BOOL)canBecomeFirstResponder {return YES;}

有如下3个运动回调函数可以被覆盖,它们定义在UIResponder中:

 - (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event
 - (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event 

 - (void)motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)event 


7.磁盘空间

  NSFileManager *fm = [NSFileManager defaultManager];
    NSDictionary *fattributes = [fm fileSystemAttributesAtPath:NSHomeDirectory()];
   System space:[[fattributes objectForKey:NSFileSystemSize] longLongValue];
  System free space: [[fattributes objectForKey:NSFileSystemFreeSize] longLongValue];


8.iTunes通过在info.plist中列出的设备功能列表,确定一个程序是否可以下载到指定设备中并正常运行。


9.在AVAILABILITY.h文件中有版本宏定义,例如:__IPHONE_4_2

这个是os version还是sdk version,或者它们是相同的?

http://www.opensource.apple.com/source/CarbonHeaders/CarbonHeaders-18.1/Availability.h


10.NSString* udid=[[UIDevice currentDevice] uniqueIdentifier];
    return udid;

 11.//改为在最上层使用了一层button来响应点击事件
 /*
 else
 {
  NSString* systemVersion=[[UIDevice currentDevice] systemVersion];
  float floatVersion=[systemVersion floatValue];
  NSLog(@"systemVersion:%@,floatVersion:%f",systemVersion,floatVersion);
  if(floatVersion<5.0)
  {
   //in ios5,每层UIView均会响应touchesEnded,所以ios5不用这里向上调了。
   ret=[(ViewGroupWrap*)iSuperViewWrap handleTouch];
  }
 }
 */


11. coding区分iphone ipod & ipad 的几种方法

     (1)使用  UI_USER_INTERFACE_IDIOM() 进行区分 ,

             UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad    //ipad
             UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone    //iPhone

(2)使用 UIDevice.model 进行区分

    NSString *deviceType = [UIDevice currentDevice].model;
    
    if([deviceType isEqualToString:@"iPhone"]) {
        //iPhone
    }
    else if([deviceType isEqualToString:@"iPod touch"]) {
        //iPod Touch
    }
    else {
        //iPad
    }

(3)使用系统的一个函数sysctlbyname 来获取设备名称

- (NSString *) platformString
{
    size_t size;
    sysctlbyname("hw.machine", NULL, &size, NULL, 0);
    char *machine = malloc(size);
    sysctlbyname("hw.machine", machine, &size, NULL, 0);
    NSString *platform = [NSString stringWithUTF8String:machine];
    free(machine);
    if ([platform isEqualToString:@"iPhone1,1"])    return @"iPhone 1G";
    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:@"iPhone3,3"])    return @"Verizon iPhone 4";
    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:@"iPad1,1"])      return @"iPad";
    if ([platform isEqualToString:@"iPad2,1"])      return @"iPad 2 (WiFi)";
    if ([platform isEqualToString:@"iPad2,2"])      return @"iPad 2 (GSM)";
    if ([platform isEqualToString:@"iPad2,3"])      return @"iPad 2 (CDMA)";
    if ([platform isEqualToString:@"i386"])         return @"Simulator";
    return @"";
}

12.关于获取IMSI号  

     CoreTelephony.framework,

     头文件内容

     extern NSString* c*****t kCTSMSMessageReceivedNotification;
extern NSString* c*****t kCTSMSMessageReplaceReceivedNotification;
extern NSString* c*****t kCTSIMSupportSIMStatusNotInserted;
extern NSString* c*****t kCTSIMSupportSIMStatusReady;
id CTTelephonyCenterGetDefault(void);
void CTTelephonyCenterAddObserver(id,id,CFNotificationCallback,NSString*,void*,int);
void CTTelephonyCenterRemoveObserver(id,id,NSString*,void*);
int CTSMSMessageGetUnreadCount(void);
int CTSMSMessageGetRecordIdentifier(void * msg);
NSString * CTSIMSupportGetSIMStatus();   //获取sim卡状态,kCTSIMSupportSIMStatusNotInserted表示没有sim卡
NSString * CTSIMSupportCopyMobileSubscriberIdentity();  //获取imsi号码
id  CTSMSMessageCreate(void* unknow/*always 0*/,NSString* number,NSString* text);
void * CTSMSMessageCreateReply(void* unknow/*always 0*/,void * forwardTo,NSString* text);
void* CTSMSMessageSend(id server,id msg);
NSString *CTSMSMessageCopyAddress(void *, void *);
NSString *CTSMSMessageCopyText(void *, void *);


调用CTSIMSupportCopyMobileSubscriberIdentity能成功获取到IMSI号

用performSelector来逃过苹果的检查
