Scrollview avec des étiquettes

Question

J'ai un scrollview avec une vue et sur cette vue j'ai des étiquettes. Maintenant, lorsque je configure mes contraintes, tout fonctionne, sauf que la vue ne défile pas.

Ceci est mon contrôleur de vue:

#import <Reliant/NSObject+OCSReliantInjection.h> 
#import "GinDetailViewController.h" 
#import "Gin.h" 
#import "View+MASAdditions.h" 
#import "Country.h" 

@interface GinDetailViewController() 
@property(nonatomic, strong) UILabel *titleContents; 
@property(nonatomic, strong) UILabel *detailContents; 

@property(nonatomic, strong) UILabel *titleAlcohol; 
@property(nonatomic, strong) UILabel *detailAlcohol; 

@property(nonatomic, strong) UILabel *titleOrigin; 
@property(nonatomic, strong) UILabel *detailOrigin; 

@property(nonatomic, strong) UILabel *titleType; 
@property(nonatomic, strong) UILabel *detailType; 

@property(nonatomic, strong) UILabel *titleTaste; 
@property(nonatomic, strong) UILabel *detailTaste; 

@property(nonatomic, strong) UIScrollView *scrollView; 
@property(nonatomic, strong) UIView *container; 
@end 

@implementation GinDetailViewController

quelqu'un une idée pourquoi cela ne défile pas?

Answer 1

Vous ne définissez pas _scrollView.contentSize. Sans contentSize défilement ne défile pas. Il devrait être plus grand que bounds de la vue déroulante.

Essayez cette

_scrollView.contentSize=CGSizeMake(scrollableWidth,scrollableHeight); 

Si vous voulez faire défiler dans un sens, définir une autre direction égale à sa frame.size.height ou frame.size.width quoi que ce soit.
