我如何从NSDictionary检索值？
我是新来的。 我已经从网站分析了10个值到一个tableview并链接到一个详细视图控制器。 如何在单击每个单元格时显示个别值？
（void）viewDidLoad {
[[self tableView] setDelegate：self]; [[self tableView] setDataSource：self]; array = [[NSMutableArray alloc] init];
[数组removeAllObjects];
NSURL * url = [NSURL URLWithString：@“https://itunes.apple.com/us/rss/topalbums/limit=10/json”]; NSURLRequest * request = [NSURLRequest requestWithURL：url];
connection = [NSURLConnection connectionWithRequest：request delegate：self];
if（connection）{webData = [[NSMutableData alloc] init]; }
- （void）connectionDidFinishLoading：（NSURLConnection *）connection {NSDictionary * allDataDictionary = [NSJSONSerialization JSONObjectWithData：webData options：0 error：nil]; NSDictionary * feed = [allDataDictionary objectForKey：@“feed”]; NSArray * arrayOfEntry = [feed objectForKey：@“entry”];
for (NSDictionary *diction in arrayOfEntry){
NSDictionary *title = [diction objectForKey:@"title"];
NSString *label = [title objectForKey:@"label"];
[array addObject:label];
}
[[self tableView] reloadData];
}
JSON数据将采用NSMutableArray格式。
NSMutableArray *allDataDictionary = [NSJSONSerialization JSONObjectWithData:webData options:0 error:nil];
int i=0;
for (i=0;i<[allDataDictionary count];i++) {
NSLog("value is %@", [NSString stringWithFormat:@"%@", [[allDataDictionary objectAtIndex:i] objectForKey:@"yourKey"]];)
}
