在我的应用程序中我正在使用ArcGIS。在那个我想搜索一个地方,并得到与该名称相关的地方。现在我想解析那些地方的所有地址并将它们放在表格视图中。键入地址后,按下搜索按钮后,我将获得地图上的所有标记。现在我试图获得地方的完整地址但我无法做到这一点。我想得到" place_addr"来自以下字符串的值可以任何一个请帮助我如何在ios中获得该值

如果您回来的确是一个字符串,那么您应该查看字符串搜索方法,例如rangeOfString。
这将返回包含您的标签“place_addr”的NSRange。
然后你想要从那一点向前搜索分号,使用相关方法rangeOfString:options:range:,搜索字符串的特定范围。
最后,您需要计算内容的范围,即在“place_addr”的NSRange结尾之后的5个字符,以及最终分号,但不包括最终分号。
然后你使用substringWithRange来提取你在上面计算的范围的字符串。
试一试,如果遇到麻烦就回来。

请尝试以下代码
- (NSArray *)findKey:(NSString *)key inString:(NSString *)allString
{
NSMutableArray *result = [[NSMutableArray alloc] initWithCapacity:1];
NSArray *splitArray = [allString componentsSeparatedByString:@";"];
for (NSString *s in splitArray) {
NSArray * keyValueArry = [s componentsSeparatedByString:@"="];
if([keyValueArry count] > 1)
{
NSString *_key = [keyValueArry objectAtIndex:0];
NSString *_value = [keyValueArry objectAtIndex:1];
if([_key isEqualToString:key])
{
[result addObject:_value];
}
}
}
return result;
}
其中key是place_addr,allString是你的样本字符串。
