Detects that the current device is an iPhone

 If([[Uidevice
Currentdevice]Userinterfaceidiom] =
Uiuserinterfaceidiomphone)

Sdks 3.2 later

Uiuserinterfaceidiomphone,// IPhone and iPod Touch style UI

Uiuserinterfaceidiompad,// IPad style UI

I just read the SDK:

@ Property(Nonatomic,Readonly,Retain)Nsstring* Model;// E.g. @ "iPhone ",
@ "IPod Touch"

This attribute can also be used.

Nsstring * devicetype = [uidevice currentdevice]. model;

You can also get the desired result.

Try it ~. No problem.

Or

You can use the screen size to check whether the iPhone or iPad is used.

Summary: there are at least three methods:

1.[[Uidevice Currentdevice]
Userinterfaceidiom] =Uiuserinterfaceidiomphone

2. [uidevice currentdevice]. Model

3. [ uiscreen
mainscreen ]
applicationframe ];
