i would like to ask you, if somebody know how to create a shadow at the end of table view as it is shown in the image bellow (click on the href :)). Best regards

The code for the top gradient, don't forget to import QuartzCore/QuartzCore.h
The .view is view controllers outlet View (UIView), the table view is it's subview.
- (void)viewDidLoad
{
UIView *gradientView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 50)] autorelease];
CAGradientLayer *gradient = [CAGradientLayer layer];
[gradient setFrame:gradientView.bounds];
gradient.colors = [NSArray arrayWithObjects:(id)[[UIColor blackColor] CGColor], (id)[[UIColor clearColor] CGColor], nil];
[self.view.layer addSublayer:gradient];
[super viewDidLoad];
}
Or you can always draw the gradient image and add it as a subview (on the root view after the scroll view, not on the scroll view directly to prevent the image from scrolling).

For example:
Collection view have four images,The user touches any cell mean its want to go to another view controller.give some idea for me friends.
Take this image as example if the user click the chrome image means it go to another view controller.
Create new UIButton, then use setImage method on it to set the image. Leave the title empty.
use this code for objc:
-(void)viewDidLoad {
UIImageView *imageview = [[UIImageView alloc]initWithFrame:CGRectMake(100.0, 100.0, 100.0, 100.0)];
[imageview setImage:[UIImage imageNamed:#"image.png"]];
[imageview setUserInteractionEnabled:YES];
UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(singleTapping:)];
[singleTap setNumberOfTapsRequired:1];
[imageview addGestureRecognizer:singleTap];
[self.view addSubview:imageview];
}
In IOS7 the UITableView does not have indentation anymore when using style=grouped. How can enable the indentation, so that the UITableView behaves like the settings app from apple?
There is a much simpler way to achieve this.
Place your UITableView away from the sides. eg: using Autolayout you'd have a leading and trailing space of 15px (or whatever you want). You're now creating the 'indentation' that Apple used to give you for free with grouped table views.
Adjust the layer to add corners and a border.
[[[self tableView] layer] setCornerRadius:5.0f];
[[[self tableView] layer] setBorderWidth:0.5f];
[[[self tableView] layer] setBorderColor:[[UIColor redColor] CGColor]];
(I can't post an image of the result because I don't yet have enough reputation)
An answer is located here, if you still looking for a solution,

Inside cellForRowAtIndexPath method, try this:
CALayer *sublayer = [CALayer layer];
UIImage *img = [UIImage imageNamed:#"blue_box_6dbcef.png"];
sublayer.backgroundColor = [[UIColor alloc] initWithPatternImage:img].CGColor;
sublayer.frame = CGRectMake(10,0,container.frame.size.width-20, 112);
//sublayer.cornerRadius = 5; // For rounded corners
UIView *bgview = [[UIView alloc] init];
bgview.backgroundColor = [UIColor clearColor];
[bgview.layer addSublayer:sublayer];
cell.backgroundView = bgview;
That will add a 10pt margin on both sides (left/right) of the cell.
I have created a custom UINavigationBar which is a tiny bit taller than Apples default navigation bar.
I can’t seem to find a way to move the UIBarButtonItem down to be directly centered between the two dashed lines.
Is there an easy way to do this? I’ve tried creating a custom button but had no success. Ideally I would just like to move the default back button down a couple of pixels.
Code used to create UINavigationBar, custom header image and UIBarButtonItem:
//Create image for navigation background
UIImage *NavigationPortraitBackground = [[UIImage imageNamed:#"navbackground.png"]
resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0, 0, 0)];
[[UINavigationBar appearance] setBackgroundImage: NavigationPortraitBackground
forBarMetrics:UIBarMetricsDefault];
//Centered title image
UIImageView *headerImage = [[UIImageView alloc] initWithImage: [UIImage imageNamed: #"hometitle.png"]];
[headerImage setFrame: CGRectMake(0, 0, 180, 49)];
self.navigationItem.titleView = headerImage;
UIBarButtonItem *backBarButtonItem = [[UIBarButtonItem alloc] init];
[backBarButtonItem setTintColor: [UIColor colorWithRed:0 green:69.0/255 blue:118.0/255 alpha:1]];
[backBarButtonItem setStyle: UIBarButtonItemStylePlain];
self.navigationItem.backBarButtonItem = backBarButtonItem;
[backBarButtonItem release];
Thanks in advance,
Create the UIBarButtonItem using a custom view. This custom view will be a UIView with the actual UIButton (as a subview) placed x pixels from the top (x=the number of pixels you want to move it down).
sorry
UIButton *myButton1 = [UIButton buttonWithType:UIButtonTypeCustom];
[myButton1 setImage:[UIImage imageNamed:#"back.png"] forState:UIControlStateNormal]; myButton1.showsTouchWhenHighlighted = YES;
myButton1.frame = CGRectMake(0.0, 3.0, 50,30);
[myButton1 addTarget:self action:#selector(back) forControlEvents:UIControlEventTouchUpInside]; UIBarButtonItem *leftButton = [[UIBarButtonItem alloc] initWithCustomView:myButton1];
self.navigationItem.leftBarButtonItem = leftButton;
I have a UIScrollView with an image that needs to be scalable. I want to have a "footer" with a black (opaque) background and white text. I wanted to have it be fixed as a footer. It will be opaque so you can see the image behind it.
I created a containing UIView for the scrollview and footer. I can get the scrollview to be smaller than the app frame and have a footer at the bottom filling in the extra space, but obviously I can't see the image behind the footer.
I also tried putting the UIScrollView and UIView (footer) inside the container and positioning them accordingly, but in this case I can't even see the footer. Any ideas?
Code I've gotten so far (executed in viewDidLoad of view controller):
CGRect appFrame = [[UIScreen mainScreen] applicationFrame];
UIView* view = [[UIView alloc] initWithFrame:appFrame];
view.backgroundColor = [UIColor blackColor];
CGRect scrollViewFrame = CGRectMake(0.0, 0.0, view.frame.size.width, view.frame.size.height - 100);
UIScrollView* scrollView = [[UIScrollView alloc] initWithFrame:scrollViewFrame];
[scrollView setCanCancelContentTouches:NO];
scrollView.clipsToBounds = YES;
scrollView.indicatorStyle = UIScrollViewIndicatorStyleWhite;
[scrollView addSubview:imageView];
[scrollView setContentSize:CGSizeMake(imageView.frame.size.width, imageView.frame.size.height)];
scrollView.minimumZoomScale = 0.7;
scrollView.maximumZoomScale = 5;
scrollView.delegate = self;
[scrollView setScrollEnabled:YES];
UIView* textView = [[UIView alloc] initWithFrame:CGRectMake(0.0, scrollViewFrame.size.height, appFrame.size.width, 100)];
// Red for testing purposes
textView.backgroundColor = [UIColor colorWithRed:1 green:0 blue:0 alpha:0.5];
[view addSubview:scrollView];
[view addSubview:textView];
self.view = view;
I assume that with "image" you mean that there is an UIImage in the scroll view, and that you want to see it through a half transparent footer view.
In this case you should not put the views beneath each other, but the footer view on top of the scroll view. You can insure it is on top by calling bringSubviewToFront or using [containerView insertSubview:footer atIndex:0]; instead of addSubview:.
Another caveat might be that you call your view view. There might be some unpredictable behavior about which view it is, so perhaps it is better to call it something else and then assign it to self.view.
I have plenty of UIScrollViews with a small non-scroll view at the bottom or the top. In most cases I don't have any overlap, and they just sit side-by-side. I create them all in InterfaceBuilder, and assign them to IBOutlets.
I put a background in my view like this:
UIImage *picture = [UIImage imageNamed:#"myImage.jpg"];
self.view.backgroundColor = [[UIColor alloc] initWithPatternImage:picture];
The problem is my picture is not big enough for the screen, so it repeat many times and its also not center in the View. How can I change that?
Thank you,
If you want to use a background image like this, then use a UIImageView, rather than the backgroundColor property of a standard view. In Interface Builder, add a UIImageView, size it to the same size as your view (adjust the struts and springs to match), give it your image, and make your view transparent.
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, size.width, size.height)];
//view. =[UIImage imageNamed:#"15-tags.png"] ;//[UIColor redColor];
UIGraphicsBeginImageContext(view.frame.size);
int iImageWid=30;
int iImageHei=30;
CGRect rcCenter=CGRectMake(view.frame.origin.x+(view.frame.size.width-iImageWid)/2, view.frame.origin.y+(view.frame.size.height-iImageHei)/2, iImageWid, iImageHei);
[[UIImage imageNamed:#"15-tags.png"] drawInRect:rcCenter];
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
view.backgroundColor = [UIColor colorWithPatternImage:image];
