[英]To detect IOS device type
我從這里找到了解決方案: 使用iPhone SDK確定設備(iPhone,iPod Touch)
通過鏈接,它建議使用庫https://gist.github.com/1323251
但是顯然圖書館已經過時了。 我在列表中找不到iPhone 5和新iPad等。
有誰知道我如何找到完整和更新的列表?
非常感謝。
您可以在以下情況下輕松檢測iphone
, iphone5
和iPad
:-
if([[UIDevice currentDevice]userInterfaceIdiom]==UIUserInterfaceIdiomPhone)
{
if ([[UIScreen mainScreen] bounds].size.height == 568.0f)
{
}
else
{
//iphone 3.5 inch screen
}
}
else
{
//[ipad]
}
我的答案:- 檢測設備類型
這是https://gist.github.com/1323251的更新版本。 發布新設備時,我將對其進行更新。
這很好用:
if([UIDevice currentDevice].userInterfaceIdiom==UIUserInterfaceIdiomPad) {
NSLog(@"IPAD");
}else{
NSLog(@"IPHONE");
}
只需添加到@Mohammad Kamran Usmani答案即可。 更具體的iPhone類型:
@import UIKit;
//Check which iPhone it is
double screenHeight = [[UIScreen mainScreen] bounds].size.height;
if(UI_USER_INTERFACE_IDIOM()==UIUserInterfaceIdiomPad)
{
NSLog(@"All iPads");
} else if (UI_USER_INTERFACE_IDIOM()== UIUserInterfaceIdiomPhone)
{
if(screenHeight == 480) {
NSLog(@"iPhone 4/4S");
smallFonts = true;
} else if (screenHeight == 568) {
NSLog(@"iPhone 5/5S/SE");
smallFonts = true;
} else if (screenHeight == 667) {
NSLog(@"iPhone 6/6S");
} else if (screenHeight == 736) {
NSLog(@"iPhone 6+, 6S+");
} else {
NSLog(@"Others");
}
}
使用以下代碼:
#import <sys/utsname.h>
- (NSString *)machineName
{
struct utsname systemInfo;
uname(&systemInfo);
NSString *temp = [NSString stringWithCString:systemInfo.machine
encoding:NSUTF8StringEncoding];
if ([temp rangeOfString:@"iPod"].location != NSNotFound)
{
return @"iPod";
}
if ([temp rangeOfString:@"iPad"].location != NSNotFound)
{
return @"iPad";
}
if ([temp rangeOfString:@"iPhone"].location != NSNotFound)
{
return @"iPhone";
}
return @"Unknown device";
}
您可以使用以下代碼
if(screenSize.width==2048 && screenSize.height==1536)
{
LetterParams.DeviceType=1;//IPadRetina
}
else if(screenSize.width==2048/2 && screenSize.height==1536/2)
{
LetterParams.DeviceType=2;//IPad Non-Retina
}
else if(screenSize.width==1136 && screenSize.height==640)
{
LetterParams.DeviceType=3;//IPhoneRetina
}
else
{
LetterParams.DeviceType=4;//IPhone & Ipod
}
我和其他人一起在GitHub上維護代碼,所以請從那里獲取最新代碼。 我們會在列表中不斷添加新設備。
Objective-C : GitHub / DeviceUtil

#include <sys/types.h>
#include <sys/sysctl.h>
- (NSString*)hardwareDescription {
NSString *hardware = [self hardwareString];
if ([hardware isEqualToString:@"iPhone1,1"]) return @"iPhone 2G";
if ([hardware isEqualToString:@"iPhone1,2"]) return @"iPhone 3G";
if ([hardware isEqualToString:@"iPhone3,1"]) return @"iPhone 4";
if ([hardware isEqualToString:@"iPhone4,1"]) return @"iPhone 4S";
if ([hardware isEqualToString:@"iPhone5,1"]) return @"iPhone 5";
if ([hardware isEqualToString:@"iPod1,1"]) return @"iPodTouch 1G";
if ([hardware isEqualToString:@"iPod2,1"]) return @"iPodTouch 2G";
if ([hardware isEqualToString:@"iPad1,1"]) return @"iPad";
if ([hardware isEqualToString:@"iPad2,6"]) return @"iPad Mini";
if ([hardware isEqualToString:@"iPad4,1"]) return @"iPad Air WIFI";
//there are lots of other strings too, checkout the github repo
//link is given at the top of this answer
if ([hardware isEqualToString:@"i386"]) return @"Simulator";
if ([hardware isEqualToString:@"x86_64"]) return @"Simulator";
return nil;
}
- (NSString*)hardwareString {
size_t size = 100;
char *hw_machine = malloc(size);
int name[] = {CTL_HW,HW_MACHINE};
sysctl(name, 2, hw_machine, &size, NULL, 0);
NSString *hardware = [NSString stringWithUTF8String:hw_machine];
free(hw_machine);
return hardware;
}
這是我想出的一種方法,重點關注用於屏幕測量功能的關鍵設備。 這是確定所需內容的快速方法。 這將最多檢測iPhone 5和第五代iPod touch。
