Thread 1:breakpoint 5.1: incompatible pointer types sending 'MWPhotoBrowser *' to parameter of type UIView

The problem is here, you are adding a ViewController and not a view where a View is expected.
[_container addSubview:browser];
Try:
[_container addSubview:browser.view];
Also, not entirely sure why you add it to a NavigationController and to _container depending on the rest of your code that might also cause problems, but the previous thing is what causes your error.

In the 'Supporting Files' folder I have an array of strings with the name of the sound files I want to play, and in the 'Supporting Files' folder I have a folder named 'Sounds', which contains the sound files.
All of my buttons play the same sound. Can someone please provide some insight. Thanks!
I think the problem may be in this line playSound:
NSString *soundName = [soundsArray objectAtIndex:(buttonPressed.tag -1)]
which is repeated in playSound2 and playSound3 with "buttonPressed.tag -2" and "buttonPressed.tag -3".
If your buttonPressed.tags are set to 1, 2, and 3, then each time "buttonPressed.tag -X" is likely evaluating to 0, and playing the sound of the first file in the array.
You are repeating the code to do the same task.
Add all your buttons IBAction to a single method (say it as playSound)
Implement the method like:
- (IBAction)playSound:(UIButton *)sender
{
NSString *soundName = [soundsArray objectAtIndex:(sender.tag -1)];
NSString *path = [[NSBundle mainBundle] pathForResource:soundName ofType:#"mp3"];
NSURL *file = [[NSURL alloc] initFileURLWithPath:path];
AVAudioPlayer *p = [[AVAudioPlayer alloc] initWithContentsOfURL:file error:nil];
self.audioPlayer = p;
[self.audioPlayer play];
}
There is no need of writing same code for each individual button.
SOLVED: prepareSounds() was never called. Here is the working code:
#import "MainViewController.h"
#interface MainViewController ()
#end
#implementation MainViewController
#synthesize audioPlayer;
#synthesize soundsArray;
-(void)prepareSounds
{
NSString *filepath= [[NSBundle mainBundle] pathForResource:#"Sound" ofType:#"plist"];
self.soundsArray = [[NSArray alloc] initWithContentsOfFile:filepath];
}
- (void)stopAudio
{
if (audioPlayer!= nil) {
[audioPlayer stop];
//do some task for changing the Image i.e setting the default image
}
}
- (IBAction)playSound:(UIButton *)sender
{
UIButton *btn = (UIButton*)sender;
NSString *soundName = [soundsArray objectAtIndex:(btn.tag - 1)];
NSString *path = [[NSBundle mainBundle] pathForResource:soundName ofType:#"mp3"];
NSURL *file = [[NSURL alloc] initFileURLWithPath:path];
AVAudioPlayer *p = [[AVAudioPlayer alloc] initWithContentsOfURL:file error:nil];
self.audioPlayer = p;
if([audioPlayer isPlaying])
{
[self stopAudio];
}
[self.audioPlayer play];

ios : scrollview not displaying images

I am a beginner and I have developed a program having full screen image scrollview which fetches images from database. but I am getting blank(white) images in output. what will be the reason behind that? plz help, my code is:
#interface GalleryImageScrollViewController ()
{
MyDatabase *data;
NSMutableArray *slideImages;
CGPoint gestureStartPoint,currentPosition;
}
-(void)putImageViewsInScrollView:(int) numberOfImageViews;
#end
#implementation GalleryImageScrollViewController
- (void)viewDidLoad
{
[super viewDidLoad];
self.FullScreenImageScroller.delegate= self;
[self putImageViewsInScrollView:slideImages.count];
}
-(void) putImageViewsInScrollView:(int)numberOfImageViews
{
data=[MyDatabase new];
slideImages=[data OpenMyDatabase:#"SELECT pic_name FROM interior" :#"pic_name"];
for(int i=0 ;i< numberOfImageViews; i++)
{
UIImageView *fullScreenImageView = [[UIImageView alloc] init];
fullScreenImageView.frame = CGRectMake((WIDTH_OF_IMAGE * i) , 0, WIDTH_OF_IMAGE, HEIGHT_OF_IMAGE);
fullScreenImageView.image = [UIImage imageNamed:[slideImages objectAtIndex:i]];
[self.FullScreenImageScroller addSubview:fullScreenImageView];
}
[self.FullScreenImageScroller setContentSize:CGSizeMake(WIDTH_OF_SCROLL_PAGE * ([slideImages count]), HEIGHT_OF_IMAGE)];
[self.FullScreenImageScroller setContentOffset:CGPointMake(0, 0)];
[self.FullScreenImageScroller scrollRectToVisible:CGRectMake(WIDTH_OF_IMAGE,0,WIDTH_OF_IMAGE,HEIGHT_OF_IMAGE) animated:NO];

UITableViewController with UIPageViewController in UIViewController

What I m Thinking to do is ? there is one MainViewController in which there are two UIViews one loaded UITableViewController and other UIPageViewController.
In TableViewController, there are list of pdf's names. But when i click of the pdf list, it does not loads the PageViewController with new pdf in context.
Pdf file names are store in .plist file, Pdfs are fetch from NSBundle or NSDocumentDirectory
In TableViewController
-(void)tableView:(UITableView*)tableView didSelectRowAtIndexPath:(NSIndexPath*)indexPath

}
As there is no reload data method for UIPageViewController. I was using UIPageViewController in UIViewController instead of that I use UINavigationController in which the UIPageViewController can be reloaded with dynamic data.So on click of UITableViewController, data is sends to UINavigationController-->UIPageViewController. This has solved the above issue.

I tried to put my code on a new project (empty application) and it worked fine, i didn't understand that error and its possible causes.
EDIT:
I tried to track the problem by elimination,and my code worked fine when i remove this method:
//Invoked when the class is instantiated in XIB
-(id)initWithCoder:(NSCoder*)aDecoder
{
self = [super initWithCoder:aDecoder];
if( self)
{
[self customInitialization];
}
return self;
}
However, when i run, my app doesn't display me the route between the two points (The purpose of the app). So this method seems important for the whole class because without it, i couldn't get the route and in the other side when it's there, the app crashes. How should i deal with this contradiction?
#Vince is putting you on the right track. Since the problem is in an NSURL method being called by a framework (Google Maps in this case) you need to debug what you are passing to the framework. You have the source for the framework also right? You can set breakpoints in loadWithStartPoint:endPoint:options:] to see what's going on.
One thing I did notice is you are passing an NSMutableArray as the endPoint param when I believe it expects an NSString.
