所以,我有UITableView,與許多行顯示大量的數據,我想使部分(如默認聯繫人應用程序及其部分)。所以有我的代碼(listViewController.m文件):如何在包含SQLite數據庫的表視圖中實現部分?
#import "FailedBanksListViewController.h"
#import "FailedBankDatabase.h"
#import "FailedBankInfo.h"
#import "FailedBanksDetailViewController.h"
#import "BIDAppDelegate.h"
@implementation FailedBanksListViewController
@synthesize failedBankInfos = _failedBankInfos;
@synthesize details = _details;
- (void)viewDidLoad {
self.view.backgroundColor=[UIColor colorWithPatternImage:[UIImage imageNamed:@"3.png"]];;
[super viewDidLoad];
self.failedBankInfos = [FailedBankDatabase database].failedBankInfos;
self.title = @"Продукты";
}
- (void)didReceiveMemoryWarning {
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
// Release any cached data, images, etc that aren't in use.
}
- (void)viewDidUnload {
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
self.failedBankInfos = nil;
self.details = nil;
}
- (void) viewWillAppear:(BOOL)animated
{
}
#pragma mark Table view methods
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return [_failedBankInfos count];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [_failedBankInfos count];
}
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
// Set up the cell...
FailedBankInfo *info = [_failedBankInfos objectAtIndex:indexPath.row];
cell.textLabel.text = info.name;
cell.detailTextLabel.text = [NSString stringWithFormat:@"%@, %@", info.city, info.state];
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
if (self.details == nil) {
self.details = [[FailedBanksDetailViewController alloc] initWithNibName:@"FailedBanksDetailViewController" bundle:nil];
}
FailedBankInfo *info = [_failedBankInfos objectAtIndex:indexPath.row];
_details.uniqueId = info.uniqueId;
[self.navigationController pushViewController:_details animated:YES];
}
- (void)dealloc {
self.failedBankInfos = nil;
}

好的,那就是你的代碼。你的問題是什麼? – Matthias 2012-03-25 18:52:23
我想在TableView中創建各個部分,我所看到的所有示例都不適用於SQlite,只是簡單的NSarrays。我想要部分內容 - 「食物」,「肉」,「魚」等,不只是第一個字母。 – Necrosoft 2012-03-25 18:55:09
你試過了什麼?問題在哪裏?簡單的說「給我你的代碼」在SO上不起作用。 – Matthias 2012-03-25 18:58:34
