建议使用单利然后定义一个宏放到pch里, 这样比较方便下面是自己封装的一个类。

(获取设备信息)上代码

/* CurrentDevice.h *//* 提供两种单利创建方式 */#import 
   
    #import 
    
     @interface CurrentDevice : NSObject+ (instancetype)sharedDeviceManager; /* 单利 */+ (instancetype)shareCurrentDevice; /* 单利 */- (id)deviceModel;/* 类型 ipad iphone ipod */- (NSString *)getDeviceVersionInfo; /* 设备信息 */- (NSString *)correspondVersion; /* 对应的设备名 iphone5 iphone5s */@end

方法实现部分

/* CurrentDevice.m文件 */#import "CurrentDevice.h"#include 
   
     /** 需要一些c的东西 要引用这个 */@implementation CurrentDevice/* 创建单利(官方推荐使用) */+ (instancetype)shareCurrentDevice {    static CurrentDevice *currentDevice = nil;    if (currentDevice == nil) {        currentDevice = [[CurrentDevice alloc] init];    }    return currentDevice;}/* 创建单利(底层实现, 比较高端) */+ (instancetype)sharedDeviceManager {    static CurrentDevice *sharedAccountManagerInstance = nil;    static dispatch_once_t predicate;    dispatch_once(&predicate, ^{        sharedAccountManagerInstance = [[self alloc] init];    });    return sharedAccountManagerInstance;}/* 返回设备类型 */- (id)deviceModel {    NSString *deviceModel = [UIDevice currentDevice].model;    return deviceModel;}/* 返回设备信息 */- (NSString *)getDeviceVersionInfo {    size_t size;    sysctlbyname("hw.machine", NULL, &size, NULL, 0);    char *machine = malloc(size);    sysctlbyname("hw.machine", machine, &size, NULL, 0);    NSString *platform = [NSString stringWithFormat:@"%s", machine];    free(machine);    return platform;}/* 返回对应的设备名 */- (NSString *)correspondVersion {    NSString *correspondVersion = [self getDeviceVersionInfo];    if ([correspondVersion isEqualToString:@"i386"])        return@"Simulator";    if ([correspondVersion isEqualToString:@"x86_64"])       return @"Simulator";    if ([correspondVersion isEqualToString:@"iPhone1,1"])   return@"iPhone 1";    if ([correspondVersion isEqualToString:@"iPhone1,2"])   return@"iPhone 3";    if ([correspondVersion isEqualToString:@"iPhone2,1"])   return@"iPhone 3S";    if ([correspondVersion isEqualToString:@"iPhone3,1"] || [correspondVersion isEqualToString:@"iPhone3,2"])   return@"iPhone 4";    if ([correspondVersion isEqualToString:@"iPhone4,1"])   return@"iPhone 4S";    if ([correspondVersion isEqualToString:@"iPhone5,1"] || [correspondVersion isEqualToString:@"iPhone5,2"])   return @"iPhone 5";    if ([correspondVersion isEqualToString:@"iPhone5,3"] || [correspondVersion isEqualToString:@"iPhone5,4"])   return @"iPhone 5C";    if ([correspondVersion isEqualToString:@"iPhone6,1"] || [correspondVersion isEqualToString:@"iPhone6,2"])   return @"iPhone 5S";    if ([correspondVersion isEqualToString:@"iPod1,1"])     return@"iPod Touch 1";    if ([correspondVersion isEqualToString:@"iPod2,1"])     return@"iPod Touch 2";    if ([correspondVersion isEqualToString:@"iPod3,1"])     return@"iPod Touch 3";    if ([correspondVersion isEqualToString:@"iPod4,1"])     return@"iPod Touch 4";    if ([correspondVersion isEqualToString:@"iPod5,1"])     return@"iPod Touch 5";    if ([correspondVersion isEqualToString:@"iPad1,1"])     return@"iPad 1";    if ([correspondVersion isEqualToString:@"iPad2,1"] || [correspondVersion isEqualToString:@"iPad2,2"] || [correspondVersion isEqualToString:@"iPad2,3"] || [correspondVersion isEqualToString:@"iPad2,4"])     return@"iPad 2";    if ([correspondVersion isEqualToString:@"iPad2,5"] || [correspondVersion isEqualToString:@"iPad2,6"] || [correspondVersion isEqualToString:@"iPad2,7"] )      return @"iPad Mini";    if ([correspondVersion isEqualToString:@"iPad3,1"] || [correspondVersion isEqualToString:@"iPad3,2"] || [correspondVersion isEqualToString:@"iPad3,3"] || [correspondVersion isEqualToString:@"iPad3,4"] || [correspondVersion isEqualToString:@"iPad3,5"] || [correspondVersion isEqualToString:@"iPad3,6"])      return @"iPad 3";    return correspondVersion;}@end

这里给一个写好的宏, 如果工程写了PCH文件的话直接放在PCH 里，如果没写, 在哪里需要获取设备信息就在那个页面引用即可。

/* 直接放里就行, 注意自己创建的类的名字, 复制过去需要改一下 */#import "CurrentDevice.h"#define DEVICEMODEL [[CurrentDevice shareCurrentDevice] deviceModel]#define DEVICEMODEL_t [[CurrentDevice sharedDeviceManager] deviceModel]#define DEVICEINFO [[CurrentDevice shareCurrentDevice] getDeviceVersionInfo]#define CORRESPONDVERSION [[CurrentDevice shareCurrentDevice] correspondVersion]

获取当前屏幕状态

直接给方法了, 这个比较简单根据home键位置判断当前屏幕状态给出对应才做

/* 判断当前屏幕状态 */- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation duration:(NSTimeInterval)duration {    switch (interfaceOrientation) {        case UIInterfaceOrientationPortrait:            /* home在下 */            self.webView.frame = CGRectMake(0 , 20, WIDTH, HEIGHT - 10);            break;        case UIInterfaceOrientationPortraitUpsideDown:            /* home在上 */            self.webView.frame = CGRectMake(0, 20, WIDTH, HEIGHT- 10);            break;        case UIInterfaceOrientationLandscapeLeft:            /* home在左 */            if ([DEVICEMODEL isEqualToString:@"iPad"]) {                self.webView.frame = CGRectMake(0 , 20, WIDTH, HEIGHT - 10);            } else {                self.webView.frame = CGRectMake(0 , 0, WIDTH, HEIGHT);            }            break;        case UIInterfaceOrientationLandscapeRight:            /* home在右 */            if ([DEVICEMODEL isEqualToString:@"iPad"]) {                self.webView.frame = CGRectMake(0 , 20, WIDTH, HEIGHT - 10);            } else {                self.webView.frame = CGRectMake(0 , 0, WIDTH, HEIGHT);            }            break;        default:            break;    }}
