iOS获取设备信息

概述iOS获取设备信息

下面是内存溢出 jb51.cc 通过网络收集整理的代码片段。

内存溢出小编现在分享给大家，也给大家做个参考。

    @property(nonatomic,Readonly,retain) Nsstring    *name;              // e.g. "My iPhone"      @property(nonatomic,retain) Nsstring    *model;             // e.g. @"iPhone",@"iPod touch"      @property(nonatomic,retain) Nsstring    *localizedModel;    // localized version of model      @property(nonatomic,retain) Nsstring    *systemname;        // e.g. @"iOS"      @property(nonatomic,retain) Nsstring    *systemVersion;     // e.g. @"4.0"      @property(nonatomic,Readonly) UIDeviceOrIEntation orIEntation;       // return current device orIEntation.  this will return UIDeviceOrIEntationUnkNown unless device orIEntation notifications are being generated.            @property(nonatomic,retain) NSUUID      *IDentifIErForvendor NS_AVAILABLE_IOS(6_0);      // a UUID that may be used to uniquely IDentify the device,same across apps from a single vendor.            @property(nonatomic,getter=isGeneratingDeviceOrIEntationNotifications) BOol generatesDeviceOrIEntationNotifications;            @property(nonatomic,getter=isBatteryMonitoringEnabled) BOol batteryMonitoringEnabled NS_AVAILABLE_IOS(3_0);  // default is NO      @property(nonatomic,Readonly) UIDeviceBatteryState          batteryState NS_AVAILABLE_IOS(3_0);  // UIDeviceBatteryStateUnkNown if monitoring Disabled      @property(nonatomic,Readonly) float                         batterylevel NS_AVAILABLE_IOS(3_0);  // 0 .. 1.0. -1.0 if UIDeviceBatteryStateUnkNown            @property(nonatomic,getter=isProximityMonitoringEnabled) BOol proximityMonitoringEnabled NS_AVAILABLE_IOS(3_0); // default is NO      @property(nonatomic,Readonly)                            BOol proximityState NS_AVAILABLE_IOS(3_0);  // always returns NO if no proximity detector            @property(nonatomic,getter=isMultitaskingSupported) BOol multitaskingSupported NS_AVAILABLE_IOS(4_0);            @property(nonatomic,Readonly) UIUserInterfaceIdiom userInterfaceIdiom NS_AVAILABLE_IOS(3_2);  

下面通过简单例子介绍这些属性！
