iOS: unable to change the height of UITableViewCell - ios

Question

I tried to follow this instruction to setup UITableView programatically, but the height of cell is unchanged. Here is the link for the instruction.
http://www.cimgf.com/2009/09/23/uitableviewcell-dynamic-height/
I have modified the code a little bit:
- (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;
}
Here is what I get:

Answer 1

self.myTB.delegate = self;
Modify the following code to set the heights for individual cells.
(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
return 100;
}
Now you set it as 100 constantly, so the height doesn't change.

Answer 2

I don't think you need to init the UITableViewCell with a frame. I think just alloc] init] autorelease] should do the trick.

Answer 3

Just use:
self.myTB.rowHeight = 100;
