一：系统权限的提示语国际化
image.png
- 在项目内新建名称为 InfoPlist.strings 的文件
-
选好locallzation
locallzation.png - 进入info.plist，选择
show Raw keys提取key
image.png - 将key 写入InfoPlist.strings：
NSAppleMusicUsageDescription = "You need to access media data to store pictures or videos.Do you allow access (yes or no)";
NSMicrophoneUsageDescription = "Use a microphone to capture sound during live broadcast,Are you allowed to turn on the microphone.";
NSPhotoLibraryAddUsageDescription = "You need to visit the album to select a picture,Do you allow access.";
二：LaunchScreen的国际化
很多时候我们也需要将启动页LaunchScreen国际化，可按照下面的步骤：
- info.plist内写入key：
Launch screen interface file base name(有就不要写了) value：LaunchScreen - 新建2个LaunchScree,名称为LaunchScreen_CH和LaunchScreen_EN
- InfoPlist.strings内对应的语言文件写入
UILaunchStoryboardName = "LaunchScreen_EN"; (英文)
UILaunchStoryboardName = "LaunchScreen_CH"; (中文)
LaunchScreen本来是可以直接选好locallzation然后国际化的，但是现在应该是苹果的bug，locallzation之后只显示英文，所以我选择用这种创建两个LaunchScreen的方式
三：获取系统当前的语言
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSArray *languages = [defaults objectForKey:@"AppleLanguages"];
四：MJRefresh的多语言加载
MJRefresh中添加多语言可以根据具体的业务需求改动，全局搜索这个方法:
+ (NSString *)mj_localizedStringForKey:(NSString *)key value:(NSString *)value
五：设置APP语言的工具类
#import <Foundation/Foundation.h>
@interface NSBundle (Language)
+ (void)setLanguage:(NSString *)language;
@end
#import "NSBundle+Language.h"
#import <objc/runtime.h>
static const char _bundle = 0;
@interface BundleEx : NSBundle
@end
@implementation BundleEx
- (NSString *)localizedStringForKey:(NSString *)key value:(NSString *)value table:(NSString *)tableName {
NSBundle *bundle = objc_getAssociatedObject(self, &_bundle);
return bundle ? [bundle localizedStringForKey:key value:value table:tableName] : [super localizedStringForKey:key value:value table:tableName];
}
@end
@implementation NSBundle (Language)
+ (void)setLanguage:(NSString *)language {
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
object_setClass([NSBundle mainBundle], [BundleEx class]);
});
objc_setAssociatedObject([NSBundle mainBundle], &_bundle, language ? [NSBundle bundleWithPath:[[NSBundle mainBundle] pathForResource:language ofType:@"lproj"]] : nil, OBJC_ASSOCIATION_RETAIN_NONATOMIC);
}
@end
使用方法：
[NSBundle setLanguage:@"zh-Hans"];
