将 NSDictionary 解析为带有自定义分隔符的字符串

发布于 2024-09-26 04:36:42 字数 573 浏览 3 评论 0原文

我有一个 NSMutableDictionary，其中包含一些值，我需要将键和值连接到一个字符串中，因此

> name = Fred
> password = cakeismyfavoritefood
> email = [email protected]

变为 name=Fred&password=cakeismyfavoritefood&[电子邮件受保护]

我该如何执行此操作？有没有办法将 NSDictionaries 连接到字符串中？

I have an NSMutableDictionary with some values in it, and I need to join the keys and values into a string, so

> name = Fred
> password = cakeismyfavoritefood
> email = [email protected]

becomes name=Fred&password=cakeismyfavoritefood&[email protected]

How can I do this? Is there a way to join NSDictionaries into strings?

您可以轻松地枚举字典键和对象：

NSMutableString *resultString = [NSMutableString string];
for (NSString* key in [yourDictionary allKeys]){
    if ([resultString length]>0)
       [resultString appendString:@"&"];
    [resultString appendFormat:@"%@=%@", key, [yourDict objectForKey:key]];
}

You can easily do that enumerating dictionary keys and objects:

NSMutableString *resultString = [NSMutableString string];
for (NSString* key in [yourDictionary allKeys]){
    if ([resultString length]>0)
       [resultString appendString:@"&"];
    [resultString appendFormat:@"%@=%@", key, [yourDict objectForKey:key]];
}

与使用块将 NSDictionary 转换为字符串？

NSMutableArray* parametersArray = [[NSMutableArray alloc] init];
[yourDictionary enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOL *stop) {
    [parametersArray addObject:[NSString stringWithFormat:@"%@=%@", key, obj]];
}];
NSString* parameterString = [parametersArray componentsJoinedByString:@"&"];
[parametersArray release];

Quite same question as Turning a NSDictionary into a string using blocks?

NSMutableArray* parametersArray = [[NSMutableArray alloc] init];
[yourDictionary enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOL *stop) {
    [parametersArray addObject:[NSString stringWithFormat:@"%@=%@", key, obj]];
}];
NSString* parameterString = [parametersArray componentsJoinedByString:@"&"];
[parametersArray release];
