滾動型與我有一個觀點和我有一些標籤是視圖中的滾動視圖標籤

Question

。現在

當我安裝我的約束一切正常，除了視圖不會滾動。

這是我的視圖控制器：

#import "GinDetailViewController.h" 
#import "Gin.h" 
#import "View+MASAdditions.h" 
#import "Country.h"

@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;

任何一個想法，爲什麼這不滾動？

Answer 1

你不設置_scrollView.contentSize。沒有contentSize滾動視圖不會滾動。它應該大於滾動視圖的bounds。

如果你想在一個方向上滾動試試這個

_scrollView.contentSize=CGSizeMake(scrollableWidth,scrollableHeight); 

，置另一方向等於其frame.size.height或frame.size.width不管它是什麼。
