GMSGeocoder-如何设置响应语言

问题描述

在国外使用我的应用时，Google GMSGeocoder会自动以本地语言返回响应.如何设置它始终以英语返回响应?

When using my app in a foreign country, the google GMSGeocoder is returning the response in local language automatically. how can I set it to always return the the response in English?

我正在使用GMS SDK 1.7，我的代码是这样的:

Im using GMS SDK 1.7 and my code is something like this:

GMSGeocoder *geoCoder = [[GMSGeocoder alloc] init];


[geoCoder reverseGeocodeCoordinate:self.cellLocation.coordinate completionHandler:^(GMSReverseGeocodeResponse *respones, NSError *err) {
    if([respones firstResult]) {

        GMSAddress* address = [respones firstResult];
        NSString* fullAddress = [NSString stringWithFormat:@"%@, %@",address.thoroughfare, address.locality];

        self.theTextField.text = fullAddress;

    } else {
        self.theTextField.text = @"";
    }
}];

推荐答案

在@DaNLtR的启发下，使用GMSGeocoder类别可以解决此问题.之后，可以将地址解析器结果设置为英语.

Using a GMSGeocoder category can solve this issue, inspired by @DaNLtRAfter that , It can set geocoder result as English .

@implementation GMSGeocoder (Load)

+(void)load {
    [[self class] setUserLanguage:@"en-CN"];// set your wanted language.
    NSLog(@"GMSGeocoder + load!");
}
- (void)dealloc {
    [[self class] resetSystemLanguage];
    NSLog(@"GMSGeocoder + dealloc!");
}
+ (void)setUserLanguage:(NSString *)userLanguage
{

    if (!userLanguage.length) {
        [[self class] resetSystemLanguage];
        return;
    }

    [[NSUserDefaults standardUserDefaults] setValue:userLanguage forKey:@"UserLanguage"];
    [[NSUserDefaults standardUserDefaults] setValue:@[userLanguage] forKey:@"AppleLanguages"];
    [[NSUserDefaults standardUserDefaults] synchronize];
}

+ (void)resetSystemLanguage
{
    [[NSUserDefaults standardUserDefaults] removeObjectForKey:@"UserLanguage"];
    [[NSUserDefaults standardUserDefaults] setValue:nil forKey:@"AppleLanguages"];
    [[NSUserDefaults standardUserDefaults] synchronize];
}
@end

为什么要归类?

A:我测试了setLanguage:在GMSGeocoder reverseGeocodeCoordinate方法之前，它不会影响地址解析器的结果.看到DaNLtR的答案后，我认为我们可以在load方法中设置setLanguge.

A:I tested setLanguage: before GMSGeocoder reverseGeocodeCoordinate method, it can't affect geocoder result. After I saw DaNLtR's answer , I think we can setLanguge in load method.

为什么要重置语言?

A:避免影响其他模块或框架.

A:Avoide affect other module or framework .
