IPad以编程方式创建UITableViewCell [英] IPad create a programmatically UITableViewCell

问题描述

好吧，我想用这个问题杀死我的整个一天。
我设置了表的大小，但问题是我无法创建一个我想要的大小的单元格。我会把代码放进去。

实际上，单元格大小是defoult，我无法理解为什么。

on viewcontroller：我在滚动中创建10个表

   - （void）viewDidLoad {
 UIScrollView * scroll = [[UIScrollView alloc] initWithFrame：CGRectMake（0,0，self.view.frame.size.width，self.view.frame.size.height）]; 
 scroll.pagingEnabled = NO; 
 NSInteger size = 50; 
 for（int i = 0; i< 10; i ++）{
 DynamicTableView * table = [[[DynamicTableView alloc] initWithFrame：CGRectMake（size，50,254,600）style：UITableViewStylePlain] autorelease ]。 
 [table setDelegate：table]; 
 [table setDataSource：table]; 
 [scroll addSubview：table]; 
尺寸+ = 300; 
} 
 scroll.contentSize = CGSizeMake（5000，self.view.frame.size.height）; 
 [self.view addSubview：scroll]; 
 [super viewDidLoad]; 
 [scroll release]; 
 
} 
  

关于DynamicTableView：

   - （UITableViewCell *）tableView：（UITableView *）tableView cellForRowAtIndexPath：（NSIndexPath *）indexPath {
 
 static NSString * CellIdentifier = @细胞; 
 
 FotoCell * cell =（FotoCell *）[tableView dequeueReusableCellWithIdentifier：CellIdentifier]; 
 if（cell == nil）{
 cell = [[[FotoCell alloc] initWithFrame：CGRectMake（0,0,50,90）] autorelease]; 
} 
 cell.titLabel.text = @iPhone发展会议; 
 cell.descLabel.text = @周六10:30; 
 cell.thumbnail.image = [UIImage imageNamed：@estadio.jpg]; 
 
 
返回单元格;在FotoCell上
} 
  

：

   - （id）initWithFrame：（CGRect）frame {
 [super initWithFrame：frame]; 
 
 self.thumbnail = [[[UIImageView alloc] initWithFrame：CGRectMake（10,10,150,90）] autorelease]; 
 self.thumbnail.opaque = YES; 
 
 [self.contentView addSubview：self.thumbnail]; 
 
 self.titLabel = [[[UILabel alloc] initWithFrame：CGRectMake（0，self.thumbnail.frame.size.height * 0.632，self.thumbnail.frame.size.width，self.thumbnail。 frame.size.height * 0.37）] autorelease]; 
 self.titLabel.opaque = YES; 
 self.titLabel.backgroundColor = [UIColor colorWithRed：0 green：0.4745098 blue：0.29019808 alpha：0.9]; 
 self.titLabel.textColor = [UIColor whiteColor]; 
 self.titLabel.font = [UIFont boldSystemFontOfSize：11]; 
 self.titLabel.numberOfLines = 2; 
 [self.thumbnail addSubview：self.titLabel]; 
 
 self.backgroundColor = [UIColor colorWithRed：0 green：0.40784314 blue：0.21568627 alpha：1.0]; 
 self.selectedBackgroundView = [[[UIView alloc] initWithFrame：self.thumbnail.frame] autorelease]; 
 self.selectedBackgroundView.backgroundColor = kHorizo​​ntalTableSelectedBackgroundColor; 
 
返回自我; 
} 
  

解决方案

您可能需要实现heightForRowAtIndexPath

ok, i want to kill my self, entire day with this problem. i set the tables size, but the problem is that i can not create a cell with the size i want. I will put code.

Acutally the cell size is the defoult one and i cant understand why.

on viewcontroller: i create 10 tables in a scroll

 - (void)viewDidLoad {
UIScrollView *scroll = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
scroll.pagingEnabled = NO;
NSInteger size=50;
for (int i = 0; i < 10; i++) {
    DynamicTableView *table = [[[DynamicTableView alloc] initWithFrame:CGRectMake(size, 50, 254, 600) style:UITableViewStylePlain] autorelease];
    [table setDelegate:table];
    [table setDataSource:table];
    [scroll addSubview:table];
    size+=300;
}
scroll.contentSize = CGSizeMake(5000, self.view.frame.size.height);
[self.view addSubview:scroll];
[super viewDidLoad];
[scroll release];

}

on DynamicTableView:

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

static NSString *CellIdentifier = @"Cell";

    FotoCell *cell = (FotoCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[FotoCell alloc] initWithFrame:CGRectMake(0, 0, 50, 90)]   autorelease];
    }
        cell.titLabel.text = @"Meeting on iPhone Development";
        cell.descLabel.text = @"Sat 10:30";
        cell.thumbnail.image = [UIImage imageNamed:@"estadio.jpg"];


return cell;
      }

on FotoCell:

     - (id)initWithFrame:(CGRect)frame{
[super initWithFrame:frame];

self.thumbnail = [[[UIImageView alloc] initWithFrame:CGRectMake(10,10,150,90)] autorelease];
self.thumbnail.opaque = YES;

[self.contentView addSubview:self.thumbnail];

self.titLabel = [[[UILabel alloc] initWithFrame:CGRectMake(0, self.thumbnail.frame.size.height * 0.632, self.thumbnail.frame.size.width, self.thumbnail.frame.size.height * 0.37)] autorelease];
self.titLabel.opaque = YES;
self.titLabel.backgroundColor = [UIColor colorWithRed:0 green:0.4745098 blue:0.29019808 alpha:0.9];
self.titLabel.textColor = [UIColor whiteColor];
self.titLabel.font = [UIFont boldSystemFontOfSize:11];
self.titLabel.numberOfLines = 2;
[self.thumbnail addSubview:self.titLabel];

self.backgroundColor = [UIColor colorWithRed:0 green:0.40784314 blue:0.21568627 alpha:1.0];
self.selectedBackgroundView = [[[UIView alloc] initWithFrame:self.thumbnail.frame] autorelease];
self.selectedBackgroundView.backgroundColor = kHorizontalTableSelectedBackgroundColor;

return self;
  }

You might need to implement heightForRowAtIndexPath
