我使用谷歌地图的地方自动完成API自动完成用户输入地址,一旦我与所需的地址的选择完成后,通过选择地址字符串从自动完成地址到谷歌地图Google地方geocode api,以获得详细的组件,问题是有时地理编码API即使自动完成API返回相同的地址有它不返回街道号,不知道它出错的地方,下面是我使用的代码和来自服务谷歌地图上的地址自动完成和地理编码API返回的diff地址
这是我如何从地理编码服务获取详细地址
NSString* address = [NSString stringWithFormat:@"http://maps.googleapis.com/maps/api/geocode/json?address=%@&sensor=false",completionText];
NSString* str = [address stringByReplacingOccurrencesOfString:@","
withString:@""];
str = [str stringByReplacingOccurrencesOfString:@" "
withString:@"+"];
NSURL *requestURL = [NSURL URLWithString:str];
NSURLRequest *request = [NSURLRequest requestWithURL:(requestURL)];
//response
NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSError *jsonParsingError = nil;
NSDictionary *locationResults = [NSJSONSerialization JSONObjectWithData:response options:0 error:&jsonParsingError];
NSLog(@"%@",locationResults);
NSDictionary* results = [[locationResults objectForKey:@"results"] objectAtIndex:0];
NSArray* address_components = [results objectForKey:@"address_components"];
for (id addr in address_components) {
NSString *long_name = [addr valueForKey:@"long_name"];
NSString *short_name = [addr valueForKey:@"short_name"];
NSString *types = [[addr valueForKey:@"types"] objectAtIndex:0];
if ([types rangeOfString:@"street_number"].location != NSNotFound)
{
streetNum = long_name;
}
else if ([types rangeOfString:@"route"].location != NSNotFound)
{
streetName = long_name;
}
else if ([types rangeOfString:@"locality"].location != NSNotFound)
{
suburb = long_name;
}
else if ([types rangeOfString:@"administrative_area_level_1"].location != NSNotFound)
{
state = short_name;
}
else if ([types rangeOfString:@"country"].location != NSNotFound)
{
country = short_name;
}
else if ([types rangeOfString:@"postal_code"].location != NSNotFound)
{
postalCode = short_name;
}
这里是地址有一个地址的例子门牌号码,但地理编码点返回它
{

}

}
以下是谷歌地图的地理编码API输出为上述自动完成地址
{
results = (
{
"address_components" = (
{
"long_name" = "Spring Lane";
"short_name" = "Spring Ln";
types = (

);
},

"long_name" = Wallacedale;
"short_name" = Wallacedale;
types = (

},
{
"long_name" = Victoria;
"short_name" = VIC;
types = (
"administrative_area_level_1",
political
);
},
{
"long_name" = Australia;
"short_name" = AU;
types = (
country,

);
},
{
"long_name" = 3303;
"short_name" = 3303;
types = (

);
}
);
"formatted_address" = "Spring Lane, Wallacedale VIC 3303, Australia";

status = OK;
}
输出行的事具有组件类型“街道号”,其中自动完成的地址字符串在开始时正确。这发生在许多地址,什么可能是错误的?还是我需要使用其他服务?其具有街道号码的地址的 实施例是下面
这是通过自动完成API返回
{
"description" : "11 Victoria Parade, Collingwood, Victoria, Australia",
"id" : "dbeebdb81c8babd166ac8f89878e88c2cba333a1",

"value" : "Victoria"
},
{
"offset" : 43,
"value" : "Australia"
}
],
"types" : [ "route", "geocode" ]
}
并且在下面发送自动完成的地址作为输入
results = (
{
"address_components" = (
{
"long_name" = 11;
"short_name" = 11;
types = (
"street_number"
);
},
{
"long_name" = "Victoria Parade";
"short_name" = "Victoria Parade";
types = (

);
},
{
"long_name" = Collingwood;
"short_name" = Collingwood;
types = (

);
},
{
"long_name" = Victoria;
"short_name" = VIC;
types = (
"administrative_area_level_1",
political
);
},
{
"long_name" = Australia;
"short_name" = AU;
types = (
country,

);
},
{
"long_name" = 3066;
"short_name" = 3066;
types = (

);
}
);
"formatted_address" = "11 Victoria Parade, Collingwood VIC 3066, Australia";
geometry = {
bounds = {
northeast = {

lng = "144.9830508";
};
southwest = {

};
location = {

};
"location_type" = "RANGE_INTERPOLATED";
viewport = {

};
southwest = {

};
};
"place_id" = EjMxMSBWaWN0b3JpYSBQYXJhZGUsIENvbGxpbmd3b29kIFZJQyAzMDY2LCBBdXN0cmFsaWE;
types = (
"street_address"
);
}
);
status = OK;
}
后由地理编码服务返回的结果
任何帮助将不胜感激。
