I have wired up a UIStackView in my storyboard and I am dynamically adding buttons to it, this works fine if I add one or two buttons but when I want to insert the third button the app crashes with the following error
017-12-27 10:41:14.315786+0800 NWMPos[39434:24150577] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'index out of bounds for arranged subview: index = 2 expected to be less than or equal to 1'

libc++abi.dylib: terminating with uncaught exception of type NSException
I have not specified anywhere (that I know of) a limit of 2 entries in the stackview so I am a bit lost here as to why I can add two buttons but not a third
Below is the code that adds the buttons

i found this code which is very helpful to avoid delay at first animation:
NSMutableArray *menuanimationImages = [[NSMutableArray alloc] init];
for (int aniCount = 1; aniCount < 21; aniCount++) {
NSString *fileLocation = [[NSBundle mainBundle] pathForResource: [NSString stringWithFormat: #"bg%i", aniCount + 1] ofType: #"png"];
// here is the code to pre-render the image
UIImage *frameImage = [UIImage imageWithContentsOfFile: fileLocation];
UIGraphicsBeginImageContext(frameImage.size);
CGRect rect = CGRectMake(0, 0, frameImage.size.width, frameImage.size.height);
[frameImage drawInRect:rect];
UIImage *renderedImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
[menuanimationImages addObject:renderedImage];
}
settingsBackground.animationImages = menuanimationImages;
But i want to use the same image sometimes - can i fill within the code above my array manually via
testArray = [[NSArray alloc] initWithObjects:[UIImage imageNamed:#"test_001.png"],
[UIImage imageNamed:#"test_002.png"],
[UIImage imageNamed:#"test_001.png"],
nil];
Thanks for ideas!
Yes you can by using this
UIImageView * animatedImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 200,200)];
testArray = [[NSArray alloc] initWithObjects:[UIImage imageNamed:#"test_001.png"], [UIImage imageNamed:#"test_002.png"],[UIImage imageNamed:#"test_001.png"],nil];
animTime =3.0;
[animatedImageView setAnimationImages:testArray] ;
animatedImageView.animationDuration = animTime;
animatedImageView.animationRepeatCount = 1;
[self.view addSubview: animatedImageView];
[animatedImageView startAnimating];
I'm parsing my data on this way:
NSDictionary *item = [tableData objectAtIndex:[indexPath row]];
[[cell textLabel] setText:[item objectForKey:#"title"]];
[[cell detailTextLabel] setText:[item objectForKey:#"description"]];
But is there a way to parse an cell image? Normally it's
UIImage *cellImage = [UIImage imageNamed:#"image.png"];
cell.imageView.image = cellImage;
But i'm searching for a way like
[[cell UIImage cellimage] ....
Something like that so i can parse an image url from json in it
is that possible?
NSURL *url = [NSURL URLWithString:[item objectForKey:#"image"]];
NSData *data = [NSData dataWithContentsOfURL:url];
cell.imageView.image = [UIImage imageWithData:data];
Set a max width for the image

I am trying to make an app that plays MP3 songs. My program flow is like this:
I have an XML file here in my website: http://jeewanaryal.web44.net/SongsXML/songsListXML.xml. It has song titles and the actual URL of those songs on the Internet. I have the following code for my Pop songs section:
NSString *urlString = #"http://jeewanaryal.web44.net/SongsXML/songsListXML.xml";
NSData *data = [NSData dataWithContentsOfURL:[NSURL URLWithString:urlString]];
NSDictionary *dict = [XMLReader dictionaryForXMLData:data error:nil];
NSArray *arrayOfSongs = [[NSArray alloc] initWithArray:[[[dict objectForKey:#"list"] objectForKey:#"songs"] objectForKey:#"song"]];
StartStopSound = [UIButton buttonWithType:UIButtonTypeRoundedRect];
StartStopSound.frame = CGRectMake(60, 360, 200, 30);
[StartStopSound setTitle:#"बजाउनुहोस" forState:UIControlStateNormal];
[StartStopSound addTarget:self action:#selector(playSong) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:StartStopSound];
back = [UIButton buttonWithType:UIButtonTypeRoundedRect];
back.frame = CGRectMake(20, 320, 100, 30);
[back setTitle:#"पछाडीको गीत " forState:UIControlStateNormal];
[back addTarget:self action:#selector(playSong) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:back];
next = [UIButton buttonWithType:UIButtonTypeRoundedRect];
next.frame = CGRectMake(200, 320, 100, 30);
[next setTitle:#"अगाडीको गीत" forState:UIControlStateNormal];
[next addTarget:self action:#selector(playSong) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:next];
NSData *myData = [[NSData alloc] init ];
NSString *urlString1 = [[NSString alloc] init];
for (NSDictionary *fruitDict in arrayOfSongs) {
UILabel *songTitle = [[UILabel alloc] initWithFrame:CGRectMake(40, 200, 300, 40)];
songTitle.text = [NSString stringWithFormat:#"%#",[[fruitDict objectForKey:#"title"] objectForKey:#"text"]];
[self.view addSubview:songTitle];
urlString1 = [NSString stringWithFormat:#"%#",[[fruitDict objectForKey:#"url"] objectForKey:#"text"]];
//NSLog(#"\n\n -- URL STRING : %# \n\n",urlString);
}
myData = [NSData dataWithContentsOfURL:[NSURL URLWithString:urlString1]];
player = [[AVAudioPlayer alloc] initWithData:myData error:nil];
[player play];
[player numberOfLoops];
[player currentTime];
This works fine for a single song; that is, it only plays the last URL of my XML file. I want to make all songs to be played one by one, making a "Next" and "Previous" button on my app.
Will you please tell me how I can implement that? I am using XMLReader.h and XMLReader.m file to parse the data from XML into my app.
You would need to store arrayOfSongs somewhere in the class. The "back" and "next" buttons would need separate actions (e.g. playPreviousSong, playNextSong). These methods would then look something like this:
-(void) playPreviousSong
{
NSString *url = [[self songs] objectAtIndex:[self songIndex] - 1];
[self playSong:url];
[self setSongIndex:[self songIndex - 1];
}
This is a crude implementation just to show how it'd fit together. Basically you need to store the list of songs and keep track of which song is "selected"/playing, then just select the next/previous one.
Edit: To answer your question in the comments, you have already extracted the array of song URLs, you simply need to keep a reference to it in the class. E.g.
#interface AudioPlayer {
NSArray *_songs;
NSUInteger *_songIndex;
}
Then in the #implementation instead of creating a arrayOfSongs variable, simply reference the array from the instance variable:
_songs = [[NSArray alloc] initWithArray:[[[dict objectForKey:#"list"] objectForKey:#"songs"] objectForKey:#"song"]];
Then in, for example, the playPreviousSong method:
-(void) playPreviousSong
{
NSString *url = [_songs objectAtIndex:_songIndex - 1];
[self playSong:url];
_songIndex--;
}
i found an issue with Photo Library Images. It not displaying first time in my View,Image View is blank while loading first time.
Because i found Asset Library block working on another thread.After reloading my View ,I can see all the Images. However first time the Image Views are Blank.
can any one tell me a good way to deal with the problem
It working with Bundle Images.
also some times console shows that

I am using this method to show images in scroll view with lazy loading. It works well.
First initialize the value of j1. And data is the image data coming from loop from an array.
dispatch_async(dispatch_get_global_queue(0,0), ^{
NSData * data = [[NSData alloc] initWithContentsOfURL:url];
if ( data == nil )
return;
dispatch_async(dispatch_get_main_queue(), ^{
__block int j1=_j;
// WARNING: is the cell still using the same data by this point??
// NSURL *url = [NSURL URLWithString: imageName];
UIImage *image = [UIImage imageWithData: data]; //image.size.height
image1=[[UIImageView alloc] initWithFrame:CGRectMake(j1,10,image.size.width,image.size.height)];
image1.image=image;
CALayer *layer = [image1 layer];
[layer setMasksToBounds:YES];
[layer setCornerRadius:0.0]; //note that when radius is 0, the border is a rectangle
[layer setBorderWidth:3.0];
[layer setBorderColor:[[UIColor whiteColor] CGColor]];
[portfolio_scroll addSubview:image1];
});
});
_j = _j+ 320;

[objectButtonArray addObject:imageButton];
[editButtonArray addObject:editButton];
}
scrollView.contentSize = backView.bounds.size;
}
can someone help me.
I think the problem is Reference name "currentObjectImage" basically when you are doing
[selectImage addObject:currentObjectImage];
it saves the reference of "currentObjectImage", where in the next iteration next image is loaded in it which creates problem.
Replace above line with
[selectImage addObject:[currentObjectImage copy]];
I think it will solve your problem.
