我已使用此代码检测设备是否为iPhone 5,以设置适当的用户界面。
( fabs( ( double )[ [ UIScreen mainScreen ] bounds ].size.height - ( double )568 ) < DBL_EPSILON )
但是,即使应用程序在iPhone 5c中运行,它也会返回0。 我还提到了How to detect iPhone 5 (widescreen devices)?但仍然更新的代码不起作用。请帮忙。
答案 0 :(得分:4)
嗯,首先你也认为iPhone5S是iPhone 5,这是不一样的。 我宁愿使用设备名称,因为您的宏可以根据需要进行扩展。
#import <sys/utsname.h>
NSString* deviceName()
{
struct utsname systemInfo;
uname(&systemInfo);
NSString *result = [NSString stringWithCString:systemInfo.machine
encoding:NSUTF8StringEncoding];
return result;
}
#define isIPhone5 [deviceName() rangeOfString:@"iPhone5,"].location != NSNotFound
#define isIPhone5S [deviceName() rangeOfString:@"iPhone6,"].location != NSNotFound
设备列表在这里:
/*

@"iPod2,1" on iPod Touch Second Generation
@"iPod3,1" on iPod Touch Third Generation
@"iPod4,1" on iPod Touch Fourth Generation

我的方法与此处的帖子有关,但可以在前缀标题中轻松使用: Detect if the device is iPhone 5s
要确保您可以在每个文件中使用此宏,请按照下列步骤操作: 创建一个新文件(让我们称之为&#34; Helperfunctions&#34;)
.h文件包含函数的定义,没有别的:
NSString* deviceName();
.m文件包含给定的deviceName-code:
#import "Helperfunctions.h"
#import <sys/utsname.h>
NSString* deviceName()
{
struct utsname systemInfo;
uname(&systemInfo);
NSString *result = [NSString stringWithCString:systemInfo.machine
encoding:NSUTF8StringEncoding];
return result;
}
在预编译的头文件中,您现在可以添加代码(或者已经在.pch中导入的另一个文件,所以它看起来像:
//
// Prefix header
//
// The contents of this file are implicitly included at the beginning of every source file.
//
#import <Availability.h>
#ifndef __IPHONE_5_0
#warning "This project uses features only available in iOS SDK 5.0 and later."
#endif
#ifdef __OBJC__
#import <UIKit/UIKit.h>
#import <Foundation/Foundation.h>
#import "Helperfunctions.h"
#define isIPhone5 [deviceName() rangeOfString:@"iPhone5,"].location != NSNotFound
#define isIPhone5S [deviceName() rangeOfString:@"iPhone6,"].location != NSNotFound
#endif

或者,如果你想要类似于你已经做过的事情,为什么不呢:
BOOL iPhone5 = [[UIScreen mainScreen] bounds] .size.height&gt; = 568;

您的应用是否有R4启动图像(如果您使用的是资产目录)或Default-568h@2x.png启动图像?如果没有,它会认为它正在3.5英寸屏幕上运行,无论它实际运行的是什么设备。
