Although i've read quite a lot related questions about adding a UIButton to a UIScrollView it doesn't work for me. When i use UIImages instead of UIButtons it works like a charm. What am i missing here? (don't mind the if's or for-loops, al those are correct, paths of images also)
for(int j = 0; j < [subcategorie count]; j++){
NSArray *product = [subcategorie objectAtIndex:(j)];
int posX = 0;
for(int k = 1; k <= [product count]; k++){
if((i-1) == currentCategory ){
//NSString *fotoName = [NSString stringWithFormat:#"images/product/%#/%#_%i.png",self.categorieen[(i-1)] ,self.categorieen[(i-1)] , k];
NSString *fotoName = [NSString stringWithFormat:#"%#_%i",self.categorieen[(i-1)] , k];
NSString *currentCategory = [NSString stringWithFormat:#"images/product/%#/", self.categorieen[(i-1)]];
NSString *path = [[NSBundle mainBundle] pathForResource:fotoName ofType:#"png" inDirectory:currentCategory];
UIButton *fotoButton = [UIButton buttonWithType:UIButtonTypeCustom];
[fotoButton setImage:[UIImage imageNamed:path] forState:UIControlStateNormal];
fotoButton.frame = CGRectMake(posX, 252, 718, 520);
fotoButton.backgroundColor = [UIColor clearColor];
self.scrollview.contentSize = CGSizeMake(posX, 252);
[self.scrollview setBounces:YES];
[self.scrollview setPagingEnabled:YES];
[self.scrollview addSubview:fotoButton];
[self.scrollview bringSubviewToFront:fotoButton];
[self.scrollview setUserInteractionEnabled:YES];
self.scrollview.userInteractionEnabled = YES;
[self addSubview: self.scrollview];
posX += 718;
NSLog(#"Fotolink = %#", fotoName);
}
}
}
Cheers
[UIImage imageNamed:path] looks incorrect,
try [UIImage imageWithData:[NSData dataWithContentsOfFile:path]
UIButton *fotoButton = [UIButton buttonWithType:UIButtonTypeCustom];
[fotoButton setImage:[UIImage imageWithData:[NSData dataWithContentsOfFile:path] forState:UIControlStateNormal];

I have four images on a viewcontroller.On the click of those images a newViewController i.e. LargeImageViewController opens. On the LargeImageViewController there is ScrollView which does horizontal scrolling. On click of every button the images on LargeImageViewController starts from image1 ,then shows image2,then image 3,then image 4.
I want that if image 2 is clicked then the images on LargeImageViewController should start image2,then image 3,then image 4.....but when it goes to previous image then it should show image 4,image3,image 2 and image1 also.
How this can be achieved??
Code that I am using are as follows:
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
// int pageCount=4;
NSArray *imgArray = [self.tripDetails valueForKey:#"Flightimageurl"];
width = [UIScreen mainScreen].bounds.size.width;
height = [UIScreen mainScreen].bounds.size.height;
_scroller = [[UIScrollView alloc]initWithFrame:
CGRectMake(0,64,width,height)];
_scroller.contentSize=CGSizeMake([imgArray count]*_scroller.bounds.size.width,_scroller.bounds.size.height);
CGRect ViewSize=_scroller.bounds;
for(int i=0;i<[imgArray count];i++)
{
UIImageView *imgView1=[[UIImageView alloc]initWithFrame:ViewSize];
NSString *ImageURL = [imgArray objectAtIndex:i];
NSData *imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:ImageURL]];
imgView1.image=[UIImage imageWithData:imageData];
[_scroller addSubview:imgView1];
[self.view addSubview:_scroller];
ViewSize =CGRectOffset(ViewSize,_scroller.bounds.size.width,0);
}
}
Kindly help with suggesting the changes.

I have four images on a Viewcontroller A .On the click of those images Viewcontroller B having UIScrollView presents that has image view and it shows all those four imgaes....Image1 ,image 2,image 3,image 4.
I want that when image 2 is clicked then image 2 appeas as the first image on Viewcontroller B ,then image 3,then image 4...Also,when user moves left then it shows previous images including image1 too.
I have searched a lot but couldn't find solution to this problem Kindly.help

I am using the following scrollview from a tutorial series. It works fine in portrait mode but the frame does not handle the switch to landscape mode. Is there a fast way to fix this? Thanks in advance.
- (void)viewDidLoad

use a global BOOL variable
BOOl isLandscape =NO;
while writing frames
situationView.frame = CGRectMake(isLandscape?0:0, isLandscape?0:0, isLandscape?320:480 , isLandscape?480:320);
in orientation method write again
if(orientation == Landscape)
{
isLandscape=YES;
}
else
{
isLandscape=NO;
}
situationView.frame = CGRectMake(isLandscape?0:0, isLandscape?0:0, isLandscape?320:480 , isLandscape?480:320);
Check it as a sample it will work depending on it you can use
A little googlefu revealed this SO thread in which Mike states loading the UIScrollView in the viewWillAppear method instead of the viewDidLoad method, then the UIScrollView should appear as desired.
Good afternoon. I use in my application iCarousel . At the moment I can not make Progress View each item carousel. The problem is that when I click on the "Download button" Progress View have added an item first . He appears fine and works , but also appears in another 2 item from another view, where it should not be . After that, when I again click the " download button " Progress View begin to be confused with each other. Please tell me exactly what I 'm doing wrong and how I act of intercourse ? I'm new to objective-c.
P.S To download the data I use AFNetworking.

To Wain:
Sorry but I can not understand your question. I pass the URL from the dictionary in the method of downloading data. In Method iCarousel I assign Progress View tag = 7 then I add a condition to hide like this:
if (([fileManager fileExistsAtPath:[NSString stringWithFormat:#"%#/%#_mag.pdf.tmp",docDir,[myDic objectForKey:#"title"]]] == YES) && (index == [self.carousel currentItemIndex]))
{
[[[view viewWithTag:7] setHidden:NO];
[[[view viewWithTag:7] setHidden:NO];
}
else
{
[[[view viewWithTag:7] setHidden:YES];
[[[view viewWithTag:7] setHidden:YES];
}
Don't create and add the progress view in pressDownload:. Instead, create it when the view is created but set it to hidden. Then when you need it just un-hide it. When you reuse a view be sure to set the appropriate value based on whether you are downloading the item at that index.
In my quiz I have several answers. Correct answers are in plist.
here it is
<array>
<dict>
<key>QuestionTitle</key>
<string>Веки являются</string>
<key>Answers</key>
<array>
<string>частью глазного яблока</string>
<string>защитным аппаратом органа зрения</string>
<string>и тем, и другим</string>
<string>ни тем, ни другим</string>
</array>
<key>CorrectAnswer</key>
<array>
<integer>0</integer>
<integer>1</integer>
</array>
</dict>
Now I can't guess how to make check for answers that User answered
I may create variables 0,1,2,3 for A,B,C,D answers but how I should compare it with CorrectAnswer Array
There is my m. file code
NSString* path = [[NSBundle mainBundle] pathForResource:#"Questions2" ofType:#"plist"];

You can compare two string like this:
if ([#"string1" isEqualToString:#"string2"]) {
// YES it s the same
}
else{
// no it s not the same
}
for example [labelA.text isEqualToString:correctAnswerString]. I recomend you to make buttons for answers: button1: firstAnswer, button2: secondAnswer and so on. When user tap on it, you can catch the sender which will be a UIButton, and if you set the button's title for the answer, you can compare the (UIButton*)sender.titleLabel.text isEqualToString:correctAnswer
// the question is: Lion is a...
UIButton* button1 = [[UIButton alloc] initWithFrame:CGRectMake(x, y, width, height)];
