[UIDevice deviceType]：无法识别的选择器发送到类 0x23a2421b0

Question

I'm using PortSIP SDK for my iOS app.

In my App when i click call button the app gives me that error.

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '+[UIDevice deviceType]: unrecognized selector sent to class 0x23a2421b0'

I think my app can't get device type.

Any advice please ? What's that error saying ?

Answer 1

I had the same error in a demo using PortSIPSDK and the problem was a problem in configuration. From docs: http://www.portsip.cn/docs/html_man/ios/html/index.html

5. Add "-ObjC" to "Build Settings"-> "Other Linker Flags"

Answer 2

Normally, UIDevice does not have deviceType member. There should be an extension in the PortSIP SDK. You should check the source code. Probably, they do not cover all cases. But you can use the below code to detect your device type.

#include <sys/sysctl.h>
#include <sys/utsname.h>


- (NSString *) platformString{

NSLog(@"[UIDevice currentDevice].model: %@",[UIDevice currentDevice].model);
NSLog(@"[UIDevice currentDevice].description: %@",[UIDevice currentDevice].description);
NSLog(@"[UIDevice currentDevice].localizedModel: %@",[UIDevice currentDevice].localizedModel);
NSLog(@"[UIDevice currentDevice].name: %@",[UIDevice currentDevice].name);
NSLog(@"[UIDevice currentDevice].systemVersion: %@",[UIDevice currentDevice].systemVersion);
NSLog(@"[UIDevice currentDevice].systemName: %@",[UIDevice currentDevice].systemName);
NSLog(@"[UIDevice currentDevice].batteryLevel: %f",[UIDevice currentDevice].batteryLevel);      
struct utsname systemInfo;
uname(&systemInfo);
NSLog(@"[NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding]: %@",[NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding]);
NSString *platform = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];
