Android side
Obtain the command message sent by Egret to the local through gameEngine.setRuntimeInterface for read and write operations. Only sharedprefference is introduced here, and the database storage is similar.
/**
* 写入
* @param context
* @param key
* @param data
*/
public static void saveData(Context context, String key, Object data){
String type = data.getClass().getSimpleName();
SharedPreferences sharedPreferences = context
.getSharedPreferences(FILE_NAME, Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPreferences.edit();
if ("Integer".equals(type)){ editor.putInt(key,
(Integer)data);
}else if ("Boolean".equals(type)){
editor.putBoolean(key, (Boolean)data);
}else if ("String".equals(type)){
editor.putString(key, (String)data);
}else if ("Float".equals(type)){
editor.putFloat(key, (Float)data);
}else if ("Long".equals(type)){
editor.putLong(key, (Long)data);
}
editor.commit();
}
/**

* @param key
* @param defValue
* @return
*/
public static Object getData (Context context , String key , Object defValue){
String type = defValue.getClass().getSimpleName() ;
SharedPreferences sharedPreferences = context.getSharedPreferences
( FILE_NAME , Context. MODE_PRIVATE ) ;
//defValue is the default value, if no data is currently available, return it if ( "Integer" .equals(type)){ return
sharedPreferences.getInt(key, (Integer)defValue);
}else if ("Boolean".equals(type)){
return sharedPreferences.getBoolean(key, (Boolean)defValue);
}else if ("String".equals(type)){
return sharedPreferences.getString(key, (String)defValue);
}else if ("Float".equals(type)){
return sharedPreferences.getFloat(key, (Float)defValue);
}else if ("Long".equals(type)){
return sharedPreferences.getLong(key, (Long)defValue);
}
return null;
}
At last
IOS side
Obtain the message sent by Egret to native through [ EgretRuntime getInstance ] setRuntimeInterface and do related processing
Only the NSUserDefaults method is introduced here, other methods are similar, and this is enough for lightweight use.
#pragma mark - write
+ (void)setItem:(NSString *)key value:(NSString *)value{
NSUserDefaults *user = [NSUserDefaultsstandardUserDefaults];
[user setObject:value forKey:key];
}
#pragma mark - read
+ (NSString *)getItem:(NSString *)key{
NSUserDefaults *user = [NSUserDefaultsstandardUserDefaults];
NSString *value = [user objectForKey:key];
return value;
}
Finish
The principle is to communicate with the local through egret to realize the native call.
