I need to change the pictures into animation video, but I don't known how to make a video, do not know to have what good method?
for example make your image names as xxxx-1.png, xxxx-2.png ...... xxxx-80.png. and paste the below code.. then the images will animate like video.
NSMutableArray* imgArray = [[NSMutableArray alloc] init];
for (int i=1; i <= 80; i++) {
[imgArray addObject:[UIImage imageNamed:[NSString stringWithFormat:#"xxxx-%d.png",i]]];
}
UIImageView* imgView = [UIImageView alloc] initWithFrame:(x,y,a,b)];
imgView.animationImages = imgArray;
imgView.animationDuration = 0.25;
imgView.animationRepeatCount = 0;
[imgView startAnimating];
[self.view addSubview:imgView];
[imgView release];

I have a images sequence animated with :
UIImageView *imgView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 120)];
[UIImage animatedImageNamed:#"spinner-" duration:1.0f];
imgView.contentMode = UIViewContentModeCenter;
imgView.animationRepeatCount = 1; // No effect
[self.view addSubView:imgView];
But the sequence keeps looping. Is there a way to control the repeat count (and keep displaying the last image) ?
In your case, using [UIImage animatedImageNamed:#"spinner-" duration:1.0f]; won't give you what you want.
For what you would like to achieve, I would recommend using UIImageView.
Usage:
First create an UIImageView object:
UIImageView *imageView = [[UIImageView alloc] initWithFrame:<FRAME_SIZE>];
Second, create an array that holds your images to be animated.
If you just have a few, do the following:
NSMutableArray *animatedImagesArray = [[NSMutableArray alloc] initWithObjects:[UIImage imageNamed:#"spinner-1.png"], [UIImage imageNamed:#"spinner-2.png"], nil];
If you have more, then you could load your images into the array like this:
for (int i = 0; i < <NUM_OF_IMAGE_COUNT>; i++)
{
[animatedImagesArray addObject:[UIImage imageNamed:[NSString stringWithFormat:#"spinner-%d%#", i, #".png"]]];
}
Once all that is done, then we configure the controls you want:
imageView.animationImages = animatedImagesArray;
imageView.animationDuration = 1.0f;
imageView.animationRepeatCount = 1.0f;
Then start animating it by:
[imageView startAnimating];
And stop the animation via:
[imageView stopAnimating];
If you would like the UIImageView to hold the last image after stopping, we would need to carry out the following before starting the animation:
imageView.image = [imageView.animationImages lastObject];
....
[imageView startAnimating];
Hope this helps.
You set the repeat count in the UIImageView object that displays your image.
UIImage *testImage = [UIImage animatedImageNamed:#"Box.jpg" duration:1.0f];
UIImageView *imgView = [[UIImageView alloc] initWithImage:testImage];
[imgView setAnimationRepeatCount:1];
I did Get images for Url.and then display on SCrollView.My code like this
NSMutableArray *al=[NSJSONSerialization JSONObjectWithData:webData options:0 error:nil];
for (NSDictionary *diction in al)
{
NSString *geting =[diction valueForKey:#"dealimage"];
NSLog(#"dealimage is %#",geting);
NSData *getdata=[[NSData alloc]initWithData:[NSData dataFromBase64String:geting]];
NSLog(#"good day %#",getdata);
dataimages=[UIImage imageWithData:getdata];
NSLog(#"dataimages %#",dataimages);
[imagesarray addObject:dataimages];
}
scrollView=[[UIScrollView alloc]init];
scrollView.delegate = self;
scrollView.scrollEnabled = YES;
int scrollWidth = 100;
scrollView.contentSize = CGSizeMake(scrollWidth,100);
scrollView.frame=CGRectMake(0, 0, 320, 100);
scrollView.backgroundColor=[UIColor yellowColor];
[self.view addSubview:scrollView];
int xOffset = 0;
imageView.image = [UIImage imageNamed:[imagesName objectAtIndex:0]];
for(int index=0; index < [imagesName count]; index++)
{
UIImageView *img = [[UIImageView alloc] init];
img.bounds = CGRectMake(10, 10, 50, 50);
img.frame = CGRectMake(5+xOffset, 0, 160, 110);
NSLog(#"image: %#",[imagesName objectAtIndex:index]);
img.image = [UIImage imageNamed:[imagesName objectAtIndex:index]];
[images insertObject:img atIndex:index];
scrollView.contentSize = CGSizeMake(scrollWidth+xOffset,110);
[scrollView addSubview:[images objectAtIndex:index]];
xOffset += 170;
}
my Problem is ScrollView is Display but Images are not add So please tell me what wrong in my code
now i need like this
I know how to get images for Url.now i need display images Horizontal ScrollView So Please give me any idea about images .
your coding is Fine, but you are assign the value of [scrollView addSubview:[images objectAtIndex:index]];, this is not the fine one, I modify your code, as per your result Want
UIScrollView *scrollVie=[[UIScrollView alloc]init];
scrollVie.delegate = self;
scrollVie.scrollEnabled = YES;
int scrollWidth = 100;
//scrollVie.contentSize = CGSizeMake(scrollWidth,100);
scrollVie.frame=CGRectMake(0, 51, self.view.frame.size.width, 100);
scrollVie.backgroundColor=[UIColor redColor];
int xOffset = 0;
for(int index=0; index < [imagesarray count]; index++)
{
UIImageView *img = [[UIImageView alloc] initWithFrame:CGRectMake(xOffset,10,160, 110)];
img.image = (UIImage*) [imagesarray objectAtIndex:index];
[scrollVie addSubview:img];
xOffset+=100;
}
[self.view addSubview:scrollVie];
scrollVie.contentSize = CGSizeMake(scrollWidth+xOffset,110);
"official" example created by Apple take a look at the StreetScroller Demo.
For the desired outcome that is shown in the picture, ie, the horizontal scroll,
Use ScrollView instead of tableview.
set the pane of scroll to horizontal and dynamically create imageview inside a loop and insert images inside it
hope it helps :)
Instead of using table view why don't you user UICollectionView with their delegates.
you can refer this - Creating a UICollectionView programmatically
It's best way to achieve your requirement.
i'm creating a app where i'm adding some UIImages as subview of UIview. Now if I delete image I want to rearrange the remaining UIImages.
How can I achieve this?
EDIT
This is what i have tried so far:
for (int i=0; i<[array count]; i++)
{
id dict = [array objectAtIndex:i];
UIImageView *imageView = [[UIImageView alloc]initWithFrame:CGRectMake(20, 100*i+100, 60, 60)];
[imageView setBackgroundColor:[UIColor clearColor]];
[imageView setTag:i+1];
[ImagesArray addObject:imageView];
[self.view addSubView: imageView];
}
Add You all Images in NSMutableArray and declare NSMutableArray in .h file.
self.imagArray = [[NSMutableArray alloc] init];
[self.imagArray addObject:[UIImage imageWithName:#"image1.png"];
.
.
.
.
[self.imagArray addObject:[UIImage imageWithName:#"image_N.png"];
And you can easily manage it for add/delete image by self.imagArray.
If you want to delete any image then also write this code
[self.imagArray removeObjectsAtIndexes:indexes];
I assume you are using array of images. Just remove the index once it's deleted and have a login to refresh the view.
Init images to array first:
for (int i=0; i<[array count]; i++)
{
id dict = [array objectAtIndex:i];
UIImageView *imageView = [[UIImageView alloc]initWithFrame:CGRectMake(20, 100*i+100, 60, 60)];
[imageView setBackgroundColor:[UIColor clearColor]];
[ImagesArray addObject:imageView];
[self.view addSubView: imageView];
}
Delete image:
NSUInteger deleteIdx = [ImagesArray indexOfObject:deleteImage];
[deleteImage removeFromSuperview];
[self relayoutViews:deleteIdx];
- (void)relayoutViews:(int)deleteIdx{
for (int i=deleteIdx; i<[ImagesArray count]; i++) {
UIImageView *imageView = [ImagesArray objectAtIndex:i];
imageView.frame = CGRectMake(20, 100*i+100, 60, 60)];
}
}
With the help of tag you can get the imageview which user want to delete .So you have to add TapGesture on UIimageView and you have to bind method for deleting image.Like this
for (int i=0; i<[array count]; i++)
{
id dict = [array objectAtIndex:i];
UIImageView *imageView = [[UIImageView alloc]initWithFrame:CGRectMake(20, 100*i+100, 60, 60)];
[imageView setBackgroundColor:[UIColor clearColor]];
UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(oneTap:)];
[singleTap setNumberOfTapsRequired:1];
[singleTap setNumberOfTouchesRequired:1];
[imageView addGestureRecognizer:singleTap];
[imageView setTag:i+1];
[ImagesArray addObject:imageView];
[self.view addSubView: imageView];
}
- (void)oneTap:(UIGestureRecognizer *)gesture {
int myViewTag = gesture.view.tag;
// Now with the help of tag you can remove object from you array and which you are want to remove and then you can reload you view
}
i have retrived images from document directory and want to display that images in scrollview. the images is coming from the document directory but not displaying in scrollview. i have the below code. I have put scrollview graipically on xib and also creat outlet..
self.scrollView.contentSize = CGSizeMake(320, 136);
self.scrollView.delegate = self;
int X=0;
for (int i = 0; i < [imageFileNames count]; i++)
{
NSString *getImagePath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:#"%d/%d.png",b, i]];
UIImage *img = [UIImage imageWithContentsOfFile:getImagePath];
[images addObject:img];
NSLog(#"%#",getImagePath);
//imge.image=img;
UIImageView *imageView = [[UIImageView alloc] initWithFrame: CGRectMake(X, 0, 100, 100)] ;
[imageView setImage: [UIImage imageNamed:[NSString stringWithFormat:#"%d.png", i]]];
[self.scrollView addSubview: imageView];
X = X + imageView.frame.size.height+5;
if(X > 320)
self.scrollView.contentSize = CGSizeMake(X, 140);
}
Seems you are trying to create the UIImageView from images that are located in your resources (but they are not there!).
[imageView setImage: [UIImage imageNamed:[NSString stringWithFormat:#"%d.png", i]]];
whats the point of placing the images in a array, if you dont use it?
try this instead:
[imageView setImage: [images objectAtIndex:i]];
I am rather new to Cocoa programming and need some help.
I want to make some image views for units in a game and add them with code, because to put them in the view and make conections in Interface Builder is a lot of work.
I already have found code to create and insert UIImageViews:
UIImageView *image0 =[[UIImageView alloc] initWithFrame:CGRecMake(x,y,w,h)];
image0.image=[UIImage imageNamed:#"image.png"];
[self.view addSubview:image0];
My question is: if I can make an array, then I don't have to write this for every image view, and I put the same image in it?
A nice way to do it would be something like this. This will create 30 image views with the same image.
NSMutableArray *arrayOfImageViews = [NSMutableArray array];
for (int i = 0; i < 30; i++) {
UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"theImage.png"]];
[self.view addSubview:imageView];
[arrayOfImageViews addObject:imageView];
}
How about this:
for(int i=0; i<10; ++i) {
UIImageView *image =[[UIImageView alloc] initWithFrame:CGRecMake(x+i*k1,y*i*k2,w,h)];
image.image=[UIImage imageNamed:#"image.png"];
image.tag = i+1;
[self.view addSubview:image0];
}
