检索设备信息React-Native iOS [英] Retrieving Device Information React-Native iOS

问题描述

嘿我正试图从iPad获取设备信息。我尝试过使用 https://github.com/rebeccahughes/react-native-device-信息但在我安装pod之后它完全破坏了我的解决方案。我希望能够至少获得设备的名称。如何在不使用NPM模块的情况下解决这个问题，或者是否有人知道哪个工作必须引入额外的依赖关系？

Hey I am trying to get device information from an iPad. I have tried using https://github.com/rebeccahughes/react-native-device-info but after I do pod install it completely break my solution. Id like to be able to at least get the device's name. How can I go about this without using an NPM module or does anyone know of one that works that doest have to pull in extra dependencies?

谢谢！

推荐答案

这可以通过本机模块，不需要库或依赖项。

This can be done easily using Native Modules, no libraries or dependencies required.

在你的JS中：

import { NativeModules} from "react-native"

const DeviceInfo = NativeModules.DeviceInfo;

const deviceName = DeviceInfo.getName();

：
RCTDeviceInfo.h

in iOS: RCTDeviceInfo.h

#import <Foundation/Foundation.h>
#import <React/RCTBridgeModule.h>

@interface RCTDeviceInfo : NSObject<RCTBridgeModule>

@end

RCTDeviceInfo.m

RCTDeviceInfo.m

#import "RCTDataLogger.h"

@implementation RCTDeviceInfo

RCT_EXPORT_MODULE(DeviceInfo);

RCT_EXPORT_BLOCKING_SYNCHRONOUS_METHOD(getName) {
    return [[UIDevice currentDevice] name];
}

@end

在你的JS中：

import { NativeModules} from "react-native"

const DeviceInfo = NativeModules.DeviceInfo;

DeviceInfo.getName().then(deviceName => {
  console.log("Current Device: "+deviceName);
}

在iOS中：
RCTDeviceInfo.h

in iOS: RCTDeviceInfo.h

#import <Foundation/Foundation.h>
#import <React/RCTBridgeModule.h>

@interface RCTDeviceInfo : NSObject<RCTBridgeModule>

@end

RCTDeviceInfo.m

RCTDeviceInfo.m

#import "RCTDataLogger.h"

@implementation RCTDeviceInfo

RCT_EXPORT_MODULE(DeviceInfo);

RCT_EXPORT_METHOD(getName
              getName_resolver:(RCTPromiseResolveBlock)resolve
              getName_rejecter:(RCTPromiseRejectBlock)reject) {
    resolve([[UIDevice currentDevice] name]);
}

@end
