我创建一个应用程序,并从 JSON 读取 TableView 中的许多数据,我想解析此 JSON 并将其存储在 sqlite 中,但我不知道应该从哪里开始?
这是解析我的 json 代码:
@implementation TableViewController
{
NSArray *news;
NSMutableData *data;
NSString *title;
NSMutableArray *all;
}
@synthesize mainTable;
- (void)viewDidLoad
{
[super viewDidLoad];
self.title = @"News";
[UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
NSURL *url = [NSURL URLWithString:@"http://zacandcatie.com/YouTube/json.php"];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
NSURLConnection *con = [[NSURLConnection alloc] initWithRequest:request delegate:self];
[con start];
}
- (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;
news = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:nil];
for (int i =0; i < [news count]; i++)
{
NSIndexPath *indexPath = [self.mainTable indexPathForSelectedRow];
title =[[news objectAtIndex:indexPath.row+i]objectForKey:@"title"];
if (!all) {
all = [NSMutableArray array];
}
[all addObject:title];
}
NSLog(@"%@",all);
[mainTable 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;
}
你是我的 json 网址。我想在 sqlite 中存储“title”和“date_string”值。 请指导我!
最佳答案
以 NSDictionary 形式解析数据后,您可以创建插入查询并触发查询,您的数据将保存到数据库中
