NSDictionary
配列の次の結果があります
Bath = {
Keynsham = (
"nsham companies"
);
};
Bath = {
"Midsomer Norton" = (
"Keynsham companies"
);
};
Bath = {
"Norton Radstock" = (
"Keynsham taxi companies"
);
};
Birmingham = {
"Acock's Green" = (
"Acock's Green taxi companies"
);
};
Birmingham = {
"Alcester Lane's End" = (
"Alcester Lane's End taxi companies"
);
};
以下に示すように、値とキーを組み合わせて、最終的に 1 つのカテゴリだけになるようにするにはどうすればよいですか。
Bath = {
"Norton Radstock" = (
"Keynsham taxi companies"
);
"Midsomer Norton" = (
"Keynsham companies"
);
Keynsham = (
"nsham companies"
);
};
これがそれを説明する最良の方法であるかどうかはわかりませんが、コードは次のとおりです
//すべての Nssarrays が割り当てられ、初期化されました
NSURL *url=[NSURL URLWithString:@"http://y.php"];
NSData *data= [NSData dataWithContentsOfURL:url];
NSMutableArray *json = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:Nil];
//instantiate arrays to hold data
NSMutableDictionary *dictArray=[[NSMutableDictionary alloc]init];
NSArray *cityName=[[NSArray alloc]init];
NSArray *townName=[[NSArray alloc]init];
NSArray *taxis=[[NSArray alloc]init];
NSArray *ids=[[NSArray alloc]init];
for (int i=0; i<json.count; i++)
{
//cityName=[[NSMutableArray alloc] initWithCapacity:json.count];
ids = [[json objectAtIndex:i] objectForKey:@"id"];
cityName = [[json objectAtIndex:i] objectForKey:@"cityName"];
townName=[[json objectAtIndex:i] objectForKey:@"townName"];
taxis=[[json objectAtIndex:i] objectForKey:@"taxis"];
NSMutableArray *taxisArray=[[NSMutableArray alloc] initWithObjects:taxis,nil];
NSMutableDictionary *towensdict=[[ NSMutableDictionary alloc] initWithObjectsAndKeys:taxisArray,townName, nil];
NSMutableDictionary *cities1=[[NSMutableDictionary alloc] initWithObjectsAndKeys:towensdict,cityName, nil];
NSLOG (@"%@", cities1) here, gives me the print out above
[dictArray addEntriesFromDictionary:cities1 ];
Then I tried Jdodgers solution as follows;
NSMutableDictionary *combinedDictionary = [[NSMutableDictionary alloc] init];
for (NSDictionary *currentDictionary in dictArray) {
NSArray *keys = [currentDictionary allKeys];
for (int n=0;n<[keys count];n++) {
NSMutableDictionary *dictionaryToAdd = [combinedDictionary valueForKey:[keys objectAtIndex:n]];
if (!dictionaryToAdd) dictionaryToAdd = [[NSMutableDictionary alloc] init];
[dictionaryToAdd setValuesForKeysWithDictionary:[currentDictionary valueForKey:[keys objectAtIndex:n]]];
[combinedDictionary setValue:dictionaryToAdd forKey:[keys objectAtIndex:n]];
NSLog(@"%@", currentDictionary);
}
}
//これにより、「認識されないセレクターがインスタンスに送信されました」というエラーが発生します。ここに出力があります
combinedDictionary NSMutableDictionary * 0x000000010012e580
currentDictionary NSDictionary *const 0x0000000100116460
