Showing UIButton Done on UIScrollview for images - ios

Question

Want to show UIButton done on UIScrollView for images. With the below code UIButton is showing but when I scroll UIImageViews, it shows only on very first imageview where as I want UIButton done should show on all image views in UIScrollView.
- (void)viewDidLoad
{
self.view.backgroundColor = [UIColor blackColor];
UIScrollView *imageScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
UIButton *myButton = [UIButton buttonWithType:UIButtonTypeCustom];
[myButton addTarget:self action:#selector(dismissView:) forControlEvents:UIControlEventTouchUpInside];
myButton.frame = CGRectMake(0, 0, 60, 35);
[myButton.layer setMasksToBounds:YES];
[myButton.layer setCornerRadius:10.0f];
myButton.layer.borderWidth = 2;
myButton.layer.borderColor = [[UIColor whiteColor] CGColor];
[myButton setTitle:#"Done" forState:UIControlStateNormal];
myButton.backgroundColor = [UIColor blackColor];
UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithCustomView:myButton];
[[self navigationItem] setRightBarButtonItem:button animated:YES];
imageScrollView.pagingEnabled = YES;
NSInteger numberOfViews = 61;
for (int i = 0; i < numberOfViews; i++) {
CGFloat xOrigin = i * self.view.frame.size.width;
NSString *imageName = [NSString stringWithFormat:#"image%d.png", i];
UIImage *image = [UIImage imageNamed:imageName];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
imageView.frame = CGRectMake(xOrigin, 0, self.view.frame.size.width, self.view.frame.size.height);
[imageScrollView addSubview:imageView];
[imageScrollView addSubview:myButton];
[imageView release];
}
imageScrollView.contentSize = CGSizeMake(self.view.frame.size.width * numberOfViews, self.view.frame.size.height);
[self.view addSubview:imageScrollView];
[imageScrollView release];
}
How should I code it that UIButton Done should show on all image views when I scroll it.

Answer 1

Add your UIButton in for loop i.e. it can add each time when your new ImageView is add.
And change its x_Origin for each imageView -
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
UIScrollView *imageScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
imageScrollView.pagingEnabled = YES;
NSInteger numberOfViews = 61;
for (int i = 0; i < numberOfViews; i++)
{
CGFloat xOrigin = i * self.view.frame.size.width;
UIButton *myButton = [UIButton buttonWithType:UIButtonTypeCustom];
[myButton addTarget:self action:#selector(dismissView) forControlEvents:UIControlEventTouchUpInside];
myButton.frame = CGRectMake(xOrigin, 0, 60, 35);
[myButton setTitle:#"Done" forState:UIControlStateNormal];
myButton.backgroundColor = [UIColor blackColor];
[myButton.layer setMasksToBounds:YES];
[myButton.layer setCornerRadius:10.0f];
myButton.layer.borderWidth = 2;
myButton.layer.borderColor = [[UIColor whiteColor] CGColor];
NSString *imageName = [NSString stringWithFormat:#"image%d.png", i];
UIImage *image = [UIImage imageNamed:imageName];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
imageView.frame = CGRectMake(xOrigin, 0, self.view.frame.size.width, self.view.frame.size.height);
[imageScrollView addSubview:imageView];
[imageScrollView addSubview:myButton];
}
imageScrollView.contentSize = CGSizeMake(self.view.frame.size.width * numberOfViews, self.view.frame.size.height);
[self.view addSubview:imageScrollView];
}
Remove these 2 lines
UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithCustomView:myButton];
[[self navigationItem] setRightBarButtonItem:button animated:YES];
There is no need to do this. This means you're setting that button on rightBarButton of NavigationBar but in your case i think you dont want to do so.

Set frame for myButton in for loop similar to imageview frame.
myButton.frame= CGRectMake(xOrigin, 0, self.myButton.frame.size.width, self.myButton.frame.size.height);
