I'm developing an app in which I have a UICollectionView. The UICollectionView has different types of UICollectionViewCells in it. For one of the Cell, I need to have different layout for different orientation.
In portrait view the cell should have the following layout
For landscape I need this layout
What is the best way to do this? Also, I have to make this work on iOS 7 devices as well. Please help.
Thanks
This will be my logic:
Add one more collectionViewCell For the landscape layout with a different reuseIdentifier.
Declare a BOOL variable like : BOOL isLAndscape;
in the implementation section.By default the bool value is NO
or False
.
Then check for the Notification if Orientation Changed! You Can set This Thing in viewDidLoad like
[[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(OrientationDidChange:) name:UIDeviceOrientationDidChangeNotification object:nil];
and whenever Orientation of your Device changed OrientationDidChange Called where You can do whatever You Want as Per Orientation.In your case ,if the orientation is landscape,then isLAndacape=YES; and then reload the collectionView.
-(void)OrientationDidChange:(NSNotification*)notification
{
UIDeviceOrientation Orientation=[[UIDevice currentDevice]orientation];
if(Orientation==UIDeviceOrientationLandscapeLeft || Orientation==UIDeviceOrientationLandscapeRight)
{
isLAndscape=YES;
[collectionVIew reloadData];
}
else if(Orientation==UIDeviceOrientationPortrait)
{
isLAndscape=NO;
[collectionVIew reloadData];
}
}
And in the cellForItemAtIndexPath
method of the collectionView,add the condition check for the bool islAndacape
and change the reuseIdentifier.
NSString *reuseIdentifier;
if(isLAndscape)
{
reuseIdentifier=@"landscapeReuseId";
}
else
{
reuseIdentifier=@"portraitReuseId";
}
Thats it!!
DISCLAIMER!!! this is my logic.I have not tried this.Check if it works.
