add uiview at row selection



I want when tab on row a uiview containing two button appear at the center of the cell, so I did the following code







- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {



//how can I get the text of the cell here?

UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];



UIView *v = [[UIView alloc] init];



v.center = cell.center;



UIButton*button1 =[[UIButton alloc] init];



button1.frame = CGRectMake(v.center.x - 5 , v.center.y , 5 , v.center.y + 4 );

button1.titleLabel.text = @"I'm label 1";



[v addSubview: button1];



UIButton*button2 =[[UIButton alloc] init];



button2.frame = CGRectMake(v.center.x - + 1 , v.center.y , 5 , v.center.y + 4 );

button2.titleLabel.text = @"I'm label 2";



[v addSubview: button2];



[cell addSubview:v];



/*

<#DetailViewController#> *detailViewController = [[<#DetailViewController#> alloc] initWithNibName:@"<#Nib name#>" bundle:nil];

// ...

// Pass the selected object to the new view controller.

[self.navigationController pushViewController:detailViewController animated:YES];

[detailViewController release];

*/

}







the uiview doesn't appear any idea how to solve that





Best regards

  1. initWithFrame is the designated initialiser for views.

    Since you are using init it doesn't know how large a view to create.

    Also UIButton *button1 = [[UIButton alloc] init]; is incorrect. UIButtons are created with the buttonWithType: class method.

  2. UIView *v = [[UIView alloc] init];//You have not set the frame of the v;

  3. try:

    [cell.contentView addSubview: v];


    It should work.

    Edit:
    Try this code. Give the frames accordingly, it will work.

    UIView *v = [[UIView alloc] initWithFrame:CGRectMake(44, 100, 200, 200)];
    UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    button.frame = CGRectMake(0, 0, 50, 50);
    [v addSubview:button];

    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    [cell.contentView addSubview:v];

Slow Android emulator

I have a 2.67 GHz Celeron processor, 1.21 GB of RAM on a x86 Windows XP Professional machine. My understanding is that the Android emulator should start fairly quickly on such a machine, but for me it does not. I have followed all instructions in setting up the IDE, SDKs, JDKs and such and have had some success in staring the emulator quickly but is very particulary. How can I, if possible, fix this problem?
