ios – 如何使视图滚动？就像Instagram的个人资料

这是我在项目中做的一个例子.我将UIView子类化并将其接收的所有触摸重定向到特定视图.在您的情况下,您将重定向所有触摸到滚动视图.

.h file:

@import UIKit.UIView;

/*!
 @class         TouchableView
 @abstract      Touchable view.
 */
@interface TouchableView : UIView

/*!
 @property      viewToReceiveTouches
 @abstract      View that receives touches instead of a given view.
 */
@property (nonatomic,weak) IBOutlet UIView *viewToReceiveTouches;

@end
.m file:

@import UIKit.UIButton;
@import UIKit.UITableView;
@import UIKit.UITextField;

#import "TouchableView.h"

@implementation TouchableView

- (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event
{
    if ( [self shouldViewReceiveTouch:self inPoint:point] )
    {
        return [super hitTest:point withEvent:event];
    }
    else if ( CGRectContainsPoint(self.bounds,point) && self.isUserInteractionEnabled )
    {
        return self.viewToReceiveTouches;
    }

    return nil;
}

- (BOOL)shouldViewReceiveTouch:(UIView *)view inPoint:(CGPoint)point
{
    if ( !CGRectContainsPoint(view.bounds,point) || !view.isUserInteractionEnabled )
    {
        return NO;
    }

    if ( [view isKindOfClass:[UIButton class]] ||
         [view isKindOfClass:[UITextField class]] ||
         [view isKindOfClass:[UITableViewCell class]] ||
         [view isKindOfClass:[UITableView class]] )

    {
        return YES;
    }

    for ( UIView *subview in view.subviews )
    {
        if ( [self shouldViewReceiveTouch:subview inPoint:[view convertPoint:point toView:subview]] )
        {
            return YES;
        }
    }

    return NO;
}

@end
