值我有2个视图控制器。在第一个我在tableview中选择一个分类。在接下来的观点我想表明categorie我在前面tableview中选定范围内的所有产品。我用一个php文件从我的数据库中获取数据。如何从以前的tableview
这是我firstViewController.m的“catVal”是我想给我下的ViewController的值。
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
KiesProduct *proView = [[KiesProduct alloc] initWithNibName:@"KiesProduct" bundle:nil];
[self.navigationController pushViewController:proView animated:YES];
NSDictionary *info = [json objectAtIndex:indexPath.row];
NSString *catVal = [info objectForKey:@"Cat_naam"];
[productVC fillArrayProducts:catVal];
}
在我的第二个视图控制器我有fillArayProducts函数。
-(void) fillArrayProducts:(NSString *)cat{
NSLog(@"test");
NSMutableString *postString = [NSMutableString stringWithString:kGETProducts];
[postString appendString:[NSString stringWithFormat:@"?%@=%@",@"Pro_cat",cat]];
[postString setString:[postString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSMutableURLRequest *request= [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:postString]];
[request setHTTPMethod:@"POST"];
postConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self startImmediately:YES];
NSData *data = [NSData dataWithContentsOfURL:[NSURL URLWithString:postString]];
NSError *error;
json = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
arrayProducts = [[NSMutableArray alloc] init];
for (int i=0; i<[json count]; i++) {
NSDictionary *info = [json objectAtIndex:i];
[arrayProducts addObject:[info objectForKey:@"Pro_naam"]];
}
NSLog(@"%@",arrayProducts);
}
我secondViewController.m
#import <UIKit/UIKit.h>
#define kGETProducts @"http://localhost/getProducts.php"
@interface KiesProduct : UITableViewController{
NSMutableArray *json;
NSMutableArray *arrayProducts;
NSURLConnection *postConnection;
}
-(IBAction)add:(id)sender;
-(void) fillArrayProducts:(NSString *)cat;
@end
当我尝试这种 '[productVC fillArrayProducts:catVal]。'在我的tableview DID选择行功能它不起作用。有人有想法吗?
好现在的工作!谢谢 ! – steaphann 2012-01-27 14:54:53
