我尝试按照此说明以编程方式设置 UITableView，但单元格的高度未更改。这是指令的链接。

我稍微修改了代码：
- (void)viewDidLoad{
[super viewDidLoad];
UITableView *tableView = [[UITableView alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, 460.0) style:UITableViewStylePlain];
self.myTB = tableView;
[tableView release];
UIView *view = [[UIView alloc] init];
[view addSubview:self.myTB];
self.view = view;
[view release];
self.myTB.dataSource = self;
items= [[NSMutableArray alloc] init];
[items addObject:@"Happiness is having a large, loving, caring, close-knit family in another city.\n\n\t\t-George Burns (1896 - 1996)"];
[items addObject:@"When I am abroad, I always make it a rule never to criticize or attack the government of my own country. I make up for lost time when I come home.\n\n\t\t-Sir Winston Churchill (1874 - 1965)"];
[items addObject:@"After two years in Washington, I often long for the realism and sincerity of Hollywood.\n\n\t\t-Fred Thompson, Speech before the Commonwealth Club of California"];
[items addObject:@"It is a profitable thing, if one is wise, to seem foolish.\n\n\t\t-Aeschylus (525 BC - 456 BC)"];
}
- (NSInteger)tableView:(UITableView*)tableView numberOfRowsInSection:(NSInteger)section{
return [items count];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
return 1;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
return 100;
}
- (UITableViewCell *)tableView:(UITableView *)tv cellForRowAtIndexPath:(NSIndexPath *)indexPath{
UITableViewCell *cell;
UILabel *label = nil;
cell = [tv dequeueReusableCellWithIdentifier:@"Cell"];
if (cell == nil){
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero ] autorelease];
label = [[UILabel alloc] initWithFrame:CGRectZero];
[label setLineBreakMode:UILineBreakModeWordWrap];
[label setMinimumFontSize:FONT_SIZE];
[label setNumberOfLines:0];
[label setFont:[UIFont systemFontOfSize:FONT_SIZE]];
[label setTag:1];
[[cell contentView] addSubview:label];
}
NSString *text = [items objectAtIndex:[indexPath row]];
CGSize constraint = CGSizeMake(CELL_CONTENT_WIDTH - (CELL_CONTENT_MARGIN * 2), 20000.0f);
CGSize size = [text sizeWithFont:[UIFont systemFontOfSize:FONT_SIZE] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];
if (!label)
label = (UILabel*)[cell viewWithTag:1];
[label setText:text];
[label setFrame:CGRectMake(CELL_CONTENT_MARGIN, CELL_CONTENT_MARGIN, CELL_CONTENT_WIDTH - (CELL_CONTENT_MARGIN * 2), MAX(size.height, 44.0f))];
return cell;
}
这是我得到的：
