是否有方法确定正在运行应用程序的设备。如果可能的话，我想区分iPhone和iPod Touch。
当前回答
- (BOOL)deviceiPhoneOriPod
{
NSString *deviceType = [UIDevice currentDevice].model;
if([deviceType rangeOfString:@"iPhone"].location!=NSNotFound)
return YES;
else
return NO;
}
其他回答
要识别iPhone 4S，只需检查以下内容:
var isIphone4S: Bool {
let width = UIScreen.main.bounds.size.width
let height = UIScreen.main.bounds.size.height
let proportions = width > height ? width / height : height / width
return proportions == 1.5 && UIDevice.current.model == "iPhone"
}
我进一步将大的“isEqualToString”块转换为设备类型、生成和逗号后的其他限定符(我称之为子生成)的位掩码分类。它被包装在一个类中，带有一个单例调用SGPlatform，避免了大量重复的字符串操作。代码可用https://github.com/danloughney/spookyGroup
这个类允许你做这样的事情:
if ([SGPlatform iPad] && [SGPlatform generation] > 3) {
// set for high performance
}
and
switch ([SGPlatform deviceMask]) {
case DEVICE_IPHONE:
break;
case DEVICE_IPAD:
break;
case DEVICE_IPAD_MINI:
break;
}
设备的分类在platformBits方法中。这个方法对于本文的读者来说应该非常熟悉。我根据设备的类型和年代对其进行了分类，因为我最感兴趣的是整体性能，但源代码可以调整以提供您感兴趣的任何分类，如视网膜屏幕、网络功能等。
我在我的应用程序中使用这个。截至2012年12月。
- (NSString *) platformString {
// Gets a string with the device model
size_t size;
sysctlbyname("hw.machine", NULL, &size, NULL, 0);
char *machine = malloc(size);
sysctlbyname("hw.machine", machine, &size, NULL, 0);
NSString *platform = [NSString stringWithCString:machine encoding:NSUTF8StringEncoding];
free(machine);
