Question

我创建了MyCalender的子类UIView，并在UIScrollView类中取MyCalender。并使用此MyCalender作为任何其他viewController的子视图。但问题是UIScrollView不滚动。我正在使用Xcode 5

MyCalender.h文件

#import <UIKit/UIKit.h>

@interface MyCalender : UIView
{
    UIScrollView *scrollMonth;
}

@property(strong,nonatomic) UIScrollView *scrollMonth;

@end


MyCalender.M file ------ 


 #import "MyCalender.h"

@implementation MyCalender
@synthesize scrollMonth;


- (id)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self) {
        // Initialization code

        scrollMonth =[[UIScrollView alloc] init];
        [scrollMonth setFrame:CGRectMake(0, 66, 320, 220)];
        [scrollMonth setContentSize:CGSizeMake(320, 500)];
        [scrollMonth setBackgroundColor:[UIColor blackColor]];
        [scrollMonth setUserInteractionEnabled:YES];

        [self addSubview:scrollMonth];

       //----------- ---------- -------- ---------


    }
    return self;
}

TestView类，其中我使用了MyCalender类

#import <UIKit/UIKit.h>
#import "MyCalender.h"


@interface testView : UIViewController
{

    MyCalender *viewCALENDER;
}
@property(strong,nonatomic) MyCalender *viewCALENDER;
@end

Testview.m

#import "testView.h"

@interface testView ()

@end

@implementation testView
@synthesize viewCALENDER;


- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.
    viewCALENDER=[[MyCalender alloc] initWithFrame:CGRectMake(0, 64, 320, 64)];
    [self.view addSubview:viewCALENDER];


}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end

从它的外观来看，您的滚动视图在viewCALENDAR：

中不可见

viewCALENDER=[[MyCalender alloc] initWithFrame:CGRectMake(0, 64, 320, 64)];
[scrollMonth setFrame:CGRectMake(0, 66, 320, 220)];

容器视图（viewCALENDAR）的高度为64px，而滚动视图的位置为66位。

澄清“不可见”＆＃39; - 如果容器视图为clipsToBounds==NO，则滚动视图可见，但在这种情况下，它不会是交互式的。

UIScrollView不在Xcode 5中滚动
