iPhone sdk how to handle orientation in UITableView CellforRowAtIndexPath? - ipad

Question

I have UIImageView, UILabel which i created in UITableView CellforRowAtIndexPath, Since i need all those in each of my cell i added to my cell.contentview. But now am facing problem in handling orientation for landscape. Since i positioned the images and labels in CellforRowAtIndexPath am getting the same position(Portrait) when am rotating for Landscape too. My code,
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
imgView1 = [[UIImageView alloc] initWithFrame:CGRectMake(680, 60, 40, 40)];
[imgView1 setImage:[UIImage imageNamed:#"Downloaded.png"]];
if([[[appDelegate selectDB] valueForKey:#"bookname"] containsObject:[listOfBooks objectAtIndex:indexPath.row]] )
{
[cell.contentView addSubview:imgView1];
}
}
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
[self handleInterfaceRotationForOrientation:toInterfaceOrientation];
if (toInterfaceOrientation==UIInterfaceOrientationLandscapeRight)
{
imgView1.frame = CGRectMake(890,0, 40, 40);
}
else if (toInterfaceOrientation==UIInterfaceOrientationLandscapeLeft)
{
imgView1.frame = CGRectMake(890,0, 40, 40);
}
else if (toInterfaceOrientation==UIInterfaceOrientationPortrait)
{
imgView1.frame = CGRectMake(690, 60, 40, 40);
}
else
{
imgView1.frame = CGRectMake(690, 60, 40, 40);
}
}
Also i tried this,
UIInterfaceOrientation orientation = [[UIDevice currentDevice] orientation];
if(orientation == UIInterfaceOrientationPortrait || orientation == UIInterfaceOrientationPortraitUpsideDown)
{
imgView = [[UIImageView alloc] initWithFrame:CGRectMake(150,20,125,163)];
imgView1 = [[UIImageView alloc] initWithFrame:CGRectMake(680, 60, 40, 40)];//self.view.bounds.size.width-
[imgView1 setImage:[UIImage imageNamed:#"Downloaded.png"]];
Label = [[UILabel alloc] initWithFrame:CGRectMake(300, 60, 370, 28)];
subtitleLabel=[[UILabel alloc]initWithFrame:CGRectMake(300,88 , 200, 23)];
subtitleLabel1=[[UILabel alloc]initWithFrame:CGRectMake(395,88 , 200, 23)];
}
else
{
imgView = [[UIImageView alloc] initWithFrame:CGRectMake(230,50,125,163)];
imgView1 = [[UIImageView alloc] initWithFrame:CGRectMake(930, 60, 40, 40)];
[imgView1 setImage:[UIImage imageNamed:#"Downloaded.png"]];
Label = [[UILabel alloc] initWithFrame:CGRectMake(420, 60, 370, 28)];
subtitleLabel=[[UILabel alloc]initWithFrame:CGRectMake(420,88 , 200, 23)];
subtitleLabel1=[[UILabel alloc]initWithFrame:CGRectMake(515,88 , 200, 23)];
}
When i tried to use the above method, i am getting only Landscape positions even in portrait. What am doing wrong here? Can someone help me? Thanks a lot in advance.

If I am reading your code right (it seems a bit out of place, but I think I get the picture) you are trying to change the image location upon device rotation. Your second set of code should work, in my opinion, but I have no idea where you put that section of code in your project. It would only work if you have it in the right place. I would do something like this:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UIInterfaceOrientation orientation = [[UIDevice currentDevice] orientation];
if(orientation == UIInterfaceOrientationPortrait || orientation == UIInterfaceOrientationPortraitUpsideDown)
{
imgView = [[UIImageView alloc] initWithFrame:CGRectMake(150,20,125,163)];
imgView1 = [[UIImageView alloc] initWithFrame:CGRectMake(680, 60, 40, 40)];//self.view.bounds.size.width-
[imgView1 setImage:[UIImage imageNamed:#"Downloaded.png"]];
Label = [[UILabel alloc] initWithFrame:CGRectMake(300, 60, 370, 28)];
subtitleLabel=[[UILabel alloc]initWithFrame:CGRectMake(300,88 , 200, 23)];
subtitleLabel1=[[UILabel alloc]initWithFrame:CGRectMake(395,88 , 200, 23)];
}
else
{
imgView = [[UIImageView alloc] initWithFrame:CGRectMake(230,50,125,163)];
imgView1 = [[UIImageView alloc] initWithFrame:CGRectMake(930, 60, 40, 40)];
[imgView1 setImage:[UIImage imageNamed:#"Downloaded.png"]];
Label = [[UILabel alloc] initWithFrame:CGRectMake(420, 60, 370, 28)];
subtitleLabel=[[UILabel alloc]initWithFrame:CGRectMake(420,88 , 200, 23)];
subtitleLabel1=[[UILabel alloc]initWithFrame:CGRectMake(515,88 , 200, 23)];
}
if([[[appDelegate selectDB] valueForKey:#"bookname"] containsObject:[listOfBooks objectAtIndex:indexPath.row]] )
{
[cell.contentView addSubview:imgView1];
}
}
So you are handling the location of all the cell contents in the cellForRowAtIndexPath:. Now you would only have to have this code to tell your tableview what to do upon rotation:
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
//self.tableView is the table containing your data
//You can animate this with the duration passed as well.
[self.tableView reloadData];
}
The willRotateToInterfaceOrientation: call has limitations in IOS6. Make sure it's actually being called when you rotate the device.
