我在 Nsarray 中有一些值，使用键值（NSDictionary 方法），我需要获取这些值分别在标签中显示这是我的数组值。

( "", "user_currency_code=USD", "user_currency_symbol=$", "usertypecode=ROBT", "player_level=1", "player_isblocked=false", "lang=en", "respond=true", "flylogin=false", "str=PageEnd", "user_balance=100000394.90", "user_bonus_balance=0.00", "first_name=test", "cash_balance=100000394.90", "coupon_balance=0.00", "str=PageEnd", "remain_GameCount=0", "remain_PTAmount=0.00", "real_user_balance=100000394.90", "fun_user_balance=95725.15", "user_bonus_balance=0.00", "bonusstatus=false", "bonus_id=null" )

在不使用索引值的情况下，我需要在标签中显示值示例 dis 值(user_currency_code=USD)键值是(user_currency_code) value(USD)，所以最后我需要在标签中显示美元，就像使用我将在标签中显示的键值一样。

据我了解

( "", "user_currency_code=USD", "user_currency_symbol=$", "usertypecode=ROBT", "player_level=1", "player_isblocked=false", "lang=en", "respond=true", "flylogin=false", "str=PageEnd", "user_balance=100000394.90", "user_bonus_balance=0.00", "first_name=test", "cash_balance=100000394.90", "coupon_balance=0.00", "str=PageEnd", "remain_GameCount=0", "remain_PTAmount=0.00", "real_user_balance=100000394.90", "fun_user_balance=95725.15", "user_bonus_balance=0.00", "bonusstatus=false", "bonus_id=null" )

它看起来不像键值编码。要从中获取值，您需要应用检查次数并需要从字符串中获取子字符串以获取实际值。您需要更改每个键值

("user_currency_code":"USD")

如果我做错了什么，请告诉我

您需要在收到此数组后立即将其转换为字典，并丢弃该数组，因为它没用：

#import <Foundation/Foundation.h>

int main(int argc, const char **argv) {
    @autoreleasepool {
        NSArray *arr = [NSArray arrayWithObjects:@"", @"user_ucurrency_code=USD", @"user_currency_symbol=$",
            @"usertypecode=ROBT", @"player_level=1", @"player_isblocked=false", @"lang=en",
            @"respond=true", @"flylogin=false", @"str=PageEnd", @"user_balance=100000394.90",
            @"user_bonus_balance=0.00", @"first_name=test", @"cash_balance=100000394.90",
            @"coupon_balance=0.00", @"str=PageEnd", @"remain_GameCount=0", @"remain_PTAmount=0.00",
            @"real_user_balance=100000394.90", @"fun_user_balance=95725.15", @"user_bonus_balance=0.00",
            @"bonusstatus=false", @"bonus_id=null", nil];

        NSMutableDictionary *dict = [NSMutableDictionary dictionary];
        for (NSString *str in arr) {
            NSArray *elements = [str componentsSeparatedByString:@"="];
            if ([elements count] != 2)
                continue;
            [dict setValue:[elements objectAtIndex:1]
                    forKey:[elements objectAtIndex:0]];
        }

        for (NSString *key in dict) {
            NSLog(@"'%@' = '%@'", key, [dict objectForKey:key]);    // or valueForKey:
        }
    }
    return 0;
}

首先你用字典排列看起来像这样： -

(
        {
        "player_isblocked" = false;
        "player_level" = 1;
        "user_currency_code" = USD;
        "user_currency_symbol" = "$";
        usertypecode = ROBT;
    }
}

我使用此代码对其进行测试：-

 NSMutableArray *ar=[[NSMutableArray alloc]init];

     NSMutableDictionary *dOfPerson=[NSMutableDictionary dictionary];

    [dOfPerson setObject:[NSString stringWithFormat:@"USD"] forKey:@"user_currency_code"];
    [dOfPerson setObject:[NSString stringWithFormat:@"$"] forKey:@"user_currency_symbol"];
    [dOfPerson setObject:[NSString stringWithFormat:@"ROBT"] forKey:@"usertypecode"];
    [dOfPerson setObject:[NSString stringWithFormat:@"1"] forKey:@"player_level"];
    [dOfPerson setObject:[NSString stringWithFormat:@"false"] forKey:@"player_isblocked"];


    [ar addObject:dOfPerson];

    NSLog(@"ar === %@",ar);

然后你必须使用这个例子来展示这个： -

yourString= [[yourArray objectAtIndex:0(here is item of index)]objectForKey:@"user_currency_code"];// user_currency_code you have write your want key



NSLog(@"%@ =====",[[ar objectAtIndex:0]objectForKey:@"user_currency_code"]);

输出是：-

USD

或者你也可以喜欢下面的方式

for (NSDictionary *dict in yourArray) {

// here you get with dic all value here try with nslog like
 NSLog(@"%@ =====",[dict valueForKey:@"yourKey");//your is is user_currency_code,user_currency_symbol etc
}
