Adjust width of Grouped UITableView - ios

Question

I have searched, with no success, for an answer to this issue. I have created a UITableView using the Grouped style. It is a landscape app for the iPad and I only want the table on the left (in the area 0, 300, 20, 748), however setting the tableView.frame = CGRectMake(0, 20, 300, 748) does nothing.
#import "ViewController.h"
#interface ViewController ()
#property (strong, nonatomic) NSArray *sections;
#end
#implementation ViewController
#synthesize sections = _sections;
- (void)viewDidLoad
{
UITableView *tableView = [[UITableView alloc] initWithFrame:CGRectMake(0, 20, 300, 748) style:UITableViewStyleGrouped];
tableView.frame = CGRectMake(0, 20, 300, 748);
tableView.delegate = self;
tableView.dataSource = self;
[tableView reloadData];
NSArray *first = [NSArray arrayWithObjects:#"first", #"second", #"third", nil];
NSArray *second = [NSArray arrayWithObjects:#"fourth", #"fifth", #"sixth", nil];
self.sections = [NSArray arrayWithObjects:first, second, nil];
self.view = tableView;
}
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return [self.sections count];
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [[self.sections objectAtIndex:section] count];
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *MyIdentifier = #"MyReuseIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:MyIdentifier];
}
cell.textLabel.text = [[self.sections objectAtIndex:[indexPath section]]objectAtIndex:[indexPath row]];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
tableView.frame = CGRectMake(0, 20, 300, 748);
return cell;
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#end
I'm looking for a way to resize the table so that it is only 300 pixels wide and on the left. Any suggestions on how this is possible?

Answer 1

Assuming your ViewController is a UIViewController, instead of making the table view the main view (which will be resized for you), simply add the table view.
Replace:
self.view = tableView;
with:
[self.view addSubview:tableView];
Now the table view will keep the frame that you set.
Since you want the table view down the left side, and presumably to fill the height, you really should do this:
- (void)viewDidLoad {
UITableView *tableView = [[UITableView alloc] initWithFrame:CGRectMake(0, 0, 300, self.view.frame.size.height) style:UITableViewStyleGrouped];
tableView.delegate = self;
tableView.dataSource = self;
NSArray *first = [NSArray arrayWithObjects:#"first", #"second", #"third", nil];
NSArray *second = [NSArray arrayWithObjects:#"fourth", #"fifth", #"sixth", nil];
self.sections = [NSArray arrayWithObjects:first, second, nil];
tableView.autoresizingMask = UIViewAutoresizingFlexibleHeight;
[self.view addSubview:tableView];
[tableView reloadData]; // don't reload until it's added and the data is ready
}
