アプリケーションでjsonを使用したい。このコードを使用して、url から json を解析できます。
#import "ViewController.h"
@implementation ViewController
{
NSDictionary *titles;
NSMutableData *Data;
NSArray *fileContent;
NSArray *folderContent;
NSMutableArray *all;
}
@synthesize Table;
- (void)viewDidLoad
{
[super viewDidLoad];
[UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
NSURL *url =[NSURL URLWithString:@"http://192.168.1.100/veis/root/developers/api/filemanager.php?key=5147379269&getlist=root"];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[[NSURLConnection alloc]initWithRequest:request delegate:self];
}
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
Data = [[NSMutableData alloc]init];
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)theData
{
[Data appendData:theData];
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
titles = [NSJSONSerialization JSONObjectWithData:Data options:kNilOptions error:nil];
fileContent = [titles objectForKey:@"fileContent"];
folderContent = [titles objectForKey:@"folderContent"];
all = [[NSMutableArray alloc]init];
[all addObjectsFromArray:folderContent];
[all addObjectsFromArray:fileContent];
[Table reloadData];
}
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
UIAlertView *errorView = [[UIAlertView alloc]initWithTitle:@"Error" message:@"The Connection has been LOST" delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil];
[errorView show];
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
}
しかし、インターネットがないときにjsonを使用できるようにしたいです。オフライン(またはデバイスのローカル)でjsonを使用する方法がわかりません
この問題で、オフラインでjsonを使用する方法を教えてもらえますか
