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
我知道答案已经被勾选了，但为了将来的参考，你可以总是使用设备屏幕大小来找出它是哪台设备:
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
CGSize result = [[UIScreen mainScreen] bounds].size;
if (result.height == 480) {
// 3.5 inch display - iPhone 4S and below
NSLog(@"Device is an iPhone 4S or below");
}
else if (result.height == 568) {
// 4 inch display - iPhone 5
NSLog(@"Device is an iPhone 5/S/C");
}
else if (result.height == 667) {
// 4.7 inch display - iPhone 6
NSLog(@"Device is an iPhone 6");
}
else if (result.height == 736) {
// 5.5 inch display - iPhone 6 Plus
NSLog(@"Device is an iPhone 6 Plus");
}
}
else if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
// iPad 9.7 or 7.9 inch display.
NSLog(@"Device is an iPad.");
}

只是将iPhone 4S设备代码添加到这个线程…
iPhone 4S将返回字符串@"iPhone4,1"。
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。

你可以像这样使用UIDevice类:
NSString *deviceType = [UIDevice currentDevice].model;
if([deviceType isEqualToString:@"iPhone"])
// it's an iPhone
