Comment travailler avec UIScrollView?

Question

Dans un de mes viewController, j'ai un ScrollView, un UIView qui contient et UIImageView, UITextView etc. pour le scrollview est ici le code que je l'ai écrit:

overViewScroll = [[UIScrollView alloc]initWithFrame:CGRectMake(0,0,screenFrame.size.width,screenFrame.size.height)]; 
     [overViewScroll setCanCancelContentTouches:NO]; 
     overViewScroll.pagingEnabled = YES; 
     overViewScroll.clipsToBounds = NO; 
     overViewScroll.indicatorStyle = UIScrollViewIndicatorStyleWhite; 
     [overViewScroll setContentSize:CGSizeMake(screenFrame.size.width, screenFrame.size.height-25)]; 
     [overViewScroll setScrollEnabled:YES]; 
     [overViewScroll setAlwaysBounceVertical:YES]; 
     [overViewScroll setShowsVerticalScrollIndicator:YES]; 

UIView * completeView = [[UIView alloc]initWithFrame:CGRectMake(0,0,screenFrame.size.width,screenFrame.size.height)]; 
    UILabel* heading1 = [[UILabel alloc]initWithFrame:CGRectMake(5,0,310,30)]; 
    heading1.text = name; 
    heading1.backgroundColor = [UIColor clearColor]; 
    UIFont * headingFont = [UIFont fontWithName:@"HelVetica" size:15]; 
    heading1.font = headingFont; 
    [completeView addSubview:heading1]; 
    //NSSet * imageString = [projectHeroData valueForKey:@"imageURL"]; 
    NSString * urlString = @""; 
    NSURL * url = [NSURL URLWithString:urlString]; 
    NSData * imageData = [NSData dataWithContentsOfURL:url]; 
    UIImage * projImage = [[UIImage alloc]initWithData:imageData]; 
    UIImageView * imgView = [[UIImageView alloc]initWithFrame:CGRectMake(screenFrame.size.width/70,screenFrame.size.height/50,screenFrame.size.width-((screenFrame.size.width/70)*2),screenFrame.size.height/3)]; 
    imgView.image = projImage; 
    imgView.backgroundColor = [UIColor blueColor]; 
    [completeView addSubview:imgView]; 

    UILabel * abstract = [[UILabel alloc]initWithFrame:CGRectMake(screenFrame.size.width/41,screenFrame.size.height/31 + screenFrame.size.height/3,screenFrame.size.width/4,screenFrame.size.height/30)]; 
    abstract.text = @"Abstract-"; 
    abstract.font = [UIFont boldSystemFontOfSize:fontSize]; 
    abstract.backgroundColor = [UIColor clearColor]; 
    [completeView addSubview:abstract]; 

    UILabel * lastUpdated = [[UILabel alloc]initWithFrame:CGRectMake(screenFrame.size.width/41 + screenFrame.size.width/5,screenFrame.size.height/31 + screenFrame.size.height/3,screenFrame.size.width-screenFrame.size.width/4,screenFrame.size.height/30)]; 
    NSString * string = modDate ; 
    NSString * updated = [NSString stringWithFormat:@"Last Updated-%@",string]; 
    lastUpdated.text = updated; 
    lastUpdated.backgroundColor = [UIColor clearColor]; 
    lastUpdated.font = [UIFont boldSystemFontOfSize:fontSize]; 
    [completeView addSubview:lastUpdated]; 

    UITextView * textView2 = [[UITextView alloc]initWithFrame:CGRectMake(screenFrame.size.width/70,(screenFrame.size.height/31 + screenFrame.size.height/3)+screenFrame.size.height/30,screenFrame.size.width-screenFrame.size.width/70*2,screenFrame.size.height)]; 
    textView2.text = abst; 
    textView2.editable = NO; 
    textView2.font = [UIFont systemFontOfSize:fontSize]; 
    textView2.backgroundColor = [UIColor clearColor]; 
    [completeView addSubview:textView2]; 

    [overViewScroll addSubview:completeView]; 
    [self.view addSubview:overViewScroll]; 

tout est addded au UIView et UIView est ajouté à l'UIScrollView. Mais le problème est qu'il se comporte bizarrement, l'image ne défile pas tout le long et le texte dans Textview défile lui-même. S'il vous plaît aider !!

Answer 1

changez le contenu de votre scrollview.votre taille de UIview et la taille de uiscrollview est la même si le contenu de UIScrollview est supérieur à sa taille de sous-vue puis défilez changez la ligne [overViewScroll setContentSize: CGSizeMake (screenFrame.size.width, screenFrame. size.height-25)]; comme ceci [overViewScroll setContentSize: CGSizeMake (screenFrame.size.width, (screenFrame.size.height-25) * 2)] ;. il vous permettra de faire défiler horizontalement et par défaut textview ayant la propriété de défilement de son auto.

Answer 2

overViewScroll =[[UIScrollViewalloc]initWithFrame:CGRectMake(0,0,screenFrame.size.width,screenFrame.size.height)]; 
    [overViewScroll setCanCancelContentTouches:NO]; 
    overViewScroll.pagingEnabled = YES; 
    overViewScroll.clipsToBounds = NO; 
    overViewScroll.indicatorStyle = UIScrollViewIndicatorStyleWhite; 
    [overViewScroll setContentSize:CGSizeMake(320,600)]; 
    [overViewScroll setScrollEnabled:YES]; 
    [overViewScroll setAlwaysBounceVertical:YES]; 
    [overViewScroll setShowsVerticalScrollIndicator:YES]; 

UIView * completeView = [[UIView alloc]initWithFrame:CGRectMake(0,0,screenFrame.size.width,screenFrame.size.height)]; 
UILabel* heading1 = [[UILabel alloc]initWithFrame:CGRectMake(5,0,310,30)]; 
heading1.text = name; 
heading1.backgroundColor = [UIColor clearColor]; 
UIFont * headingFont = [UIFont fontWithName:@"HelVetica" size:15]; 
heading1.font = headingFont; 
[completeView addSubview:heading1]; 
//NSSet * imageString = [projectHeroData valueForKey:@"imageURL"]; 
NSString * urlString = @""; 
NSURL * url = [NSURL URLWithString:urlString]; 
NSData * imageData = [NSData dataWithContentsOfURL:url]; 
UIImage * projImage = [[UIImage alloc]initWithData:imageData]; 
UIImageView * imgView = [[UIImageView alloc]initWithFrame:CGRectMake(screenFrame.size.width/70,screenFrame.size.height/50,screenFrame.size.width-((screenFrame.size.width/70)*2),screenFrame.size.height/3)]; 
imgView.image = projImage; 
imgView.backgroundColor = [UIColor blueColor]; 
[completeView addSubview:imgView]; 

UILabel * abstract = [[UILabel alloc]initWithFrame:CGRectMake(screenFrame.size.width/41,screenFrame.size.height/31 + screenFrame.size.height/3,screenFrame.size.width/4,screenFrame.size.height/30)]; 
abstract.text = @"Abstract-"; 
abstract.font = [UIFont boldSystemFontOfSize:fontSize]; 
abstract.backgroundColor = [UIColor clearColor]; 
[completeView addSubview:abstract]; 

UILabel * lastUpdated = [[UILabel alloc]initWithFrame:CGRectMake(screenFrame.size.width/41 + screenFrame.size.width/5,screenFrame.size.height/31 + screenFrame.size.height/3,screenFrame.size.width-screenFrame.size.width/4,screenFrame.size.height/30)]; 
NSString * string = modDate ; 
NSString * updated = [NSString stringWithFormat:@"Last Updated-%@",string]; 
lastUpdated.text = updated; 
lastUpdated.backgroundColor = [UIColor clearColor]; 
lastUpdated.font = [UIFont boldSystemFontOfSize:fontSize]; 
[completeView addSubview:lastUpdated]; 

UITextView * textView2 = [[UITextView alloc]initWithFrame:CGRectMake(screenFrame.size.width/70,(screenFrame.size.height/31 + screenFrame.size.height/3)+screenFrame.size.height/30,screenFrame.size.width-screenFrame.size.width/70*2,screenFrame.size.height)]; 
textView2.text = abst; 
textView2.editable = NO; 
textView2.font = [UIFont systemFontOfSize:fontSize]; 
textView2.backgroundColor = [UIColor clearColor]; 
[completeView addSubview:textView2]; 

[overViewScroll addSubview:completeView]; 
[self.view addSubview:overViewScroll]; 

Essayez ceci cela va fonctionner. Une autre façon est uYse interface builder et sélectionnez scoll view et faites glisser et déposez d'autres vues d'étiquettes sur la vue déroulante.
