我想在我的应用程序打开时将loc-args数组的第二个元素从推送通知有效负载设置为loc-key转换,例如在didReceiveRemoteNotification
方法中。
有效负载中loc-args的示例是一个包含两个元素的数组:
[
"Apple",
"1 Infinite Loop Cupertino, CA 95014"
]
loc键的翻译是:
Goto address: %2$@
如果推送消息在应用程序处于后台时到达,则可以正常工作。该消息显示为:
Goto address: 1 Infinite Loop Cupertino, CA 95014
但如果应用程序位于前台,我必须自己在didReceiveRemoteNotification
方法中处理它,例如:
let message = String(format: "Goto address: %2$@",
arguments: ["Apple", "1 Infinite Loop Cupertino, CA 95014"])
但是这会得到结果:Goto address: Apple
而不是Goto address: 1 Infinite Loop Cupertino, CA 95014
有谁能告诉我如何解决这个问题?
额外信息:
如果我将loc键更改为:Goto address: %2$@ - %1$@
,则文字将为:Goto address: 1 Infinite Loop Cupertino, CA 95014 - Apple
感谢。

直到更好的解决方案,我执行以下循环:
#include <regex>
#include <string>
#include <iostream>
#include <vector>
#define isthirty(x) for (int i = 0; i < 3; i++) {if (days[i] == x[1]) {thirty = true;break;}}
using namespace std;
int main() {
vector<string> words;
string str;
getline(cin, str);
int N = stoi(str);
int days[] = { 4,6,9,11 };
regex exp1("[^a-zA-Z0-9]([1-9][0-9]{3}(?:-[0-9][1-9]){2})[^a-zA-Z0-9]");
for (int i = 0; i < N; i++) {
getline(cin, str);
sregex_iterator it(str.cbegin(), str.cend(), exp1);
sregex_iterator end;
for (; it != end; it++) {
words.push_back(it->str(0));
}
}
regex exp2("([0-9])+");
for (auto &it : words) {
int dates[3] = {};
sregex_iterator pos(it.cbegin(), it.cend(), exp2);
sregex_iterator end;
str = it.substr(1,10);
for (int i = 0; pos != end; pos++, i++) {
dates[i] = stoi(pos->str(0));
}
if (dates[0] > 2016 || dates[1] > 12 || dates[2] > 31) {
continue;
}
bool thirty = false;
isthirty(dates);
if (thirty && dates[2] <= 30) {
cout << str << "\n";
}
else if(dates[1] == 2) {
if (dates[0] % 4 == 0 && dates[2] <= 29) {
cout << str << "\n";
}
else if (dates[0] % 4 != 0 && dates[2] <= 28) {
cout << str << "\n";
}
}
else if (dates[2] <= 31) {
cout << str << "\n";
}
}
return 0;
}

你只有一个“@”所以字符串只能得到“苹果”。我认为这个位置在两者都有效时会起作用

这里有一个从Swift代码到Obj-C的分支
NSString *message = NSLocalizedString(locKey);
NSString *format = @"";
for (int i=0; i<[args count]; i++) {
format = [NSString stringWithFormat:@"%%%d$@", i+1];
message = [message stringByReplacingOccurrencesOfString:format withString:args[i]];
}
