Question

如何使用动态数组计数动态制作具有多个部分的 uitableview？

Answer 1

检查这个长代码，我想这会派上用场

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

#pragma mark TableView

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
    return [self.words count];
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
    return [[self.words objectAtIndex:section]count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{

//    UITableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:@"cell"];
//    if (cell==nil) {
//        cell=[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"cell"];
//    }

    //UITableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:@"cell"];
    //if (cell==nil) {
      UITableViewCell *cell=[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"cell"];
    //}

    cell.textLabel.text=[[self.words objectAtIndex:indexPath.section]objectAtIndex:indexPath.row];
    cell.detailTextLabel.text=[NSString stringWithFormat:@"This is detailed subtitle for %@.",cell.textLabel.text];
    //cell.accessoryType=UITableViewCellAccessoryDetailDisclosureButton;

    NSString *imagePath=[[NSBundle mainBundle]pathForResource:@"images" ofType:@"jpeg"];
    UIImage *image=[[UIImage alloc]initWithContentsOfFile:imagePath];
    cell.imageView.image=image;


    return cell;

}

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section{
    return [self.alphabets objectAtIndex:section];
}

- (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView;{
    return self.alphabets;
}

#pragma mark -
#pragma mark Default



- (void)viewDidLoad
{

    self.alphabets=[NSMutableArray new];
    for (char i=97; i<123; i++) {
        [self.alphabets addObject:[[NSString stringWithFormat:@"%c",i]capitalizedString]];
    }

    self.words=[NSMutableArray new];
    for (NSString *character in _alphabets) {
        NSMutableArray *twoD=[NSMutableArray new];
        for (int i=1; i<(rand()%10)+1; i++) { //fill randamly any number 1 to 10.
            [twoD addObject:[NSString stringWithFormat:@"%@%d",character,i]];
        }
        [self.words addObject:twoD];
    }

    // NSLog(@"->%@",self.words);


    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}
