IOS开发之文本复制

原始地址：IOS开发之文本复制

本文基于富文本:DTCoreText

#import <Foundation/Foundation.h>
#import <MobileCoreServices/UTCoreTypes.h>//添加此框架

@interface UIPasteboard (AttributedString)
- (void) setAttributedString:(NSAttributedString *)attributedString;
@end

#import "UIPasteboard+AttributedString.h"

@implementation UIPasteboard (AttributedString)
- (void) setAttributedString:(NSAttributedString *)attributedString
{
	//\ufffc为对象占位符，目的是当富文本中有图像时，只复制文本信息！！！
	NSString *htmlString = [[attributedString string] stringByReplacingOccurrencesOfString:@"\ufffc" withString:@""];
	NSMutableDictionary *item = [NSMutableDictionary dictionaryWithCapacity:1];
	[item setValue:htmlString forKey:(NSString *)kUTTypeText];
	self.items = [NSArray arrayWithObject:item];
}
@end

给要复制的视图添加长按事件：

UILongPressGestureRecognizer *gestureRecognizer = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longTap:)];
		[self.selectedBackgroundView addGestureRecognizer:gestureRecognizer];
		gestureRecognizer.minimumPressDuration = 1.0;

- (void)longTap:(UILongPressGestureRecognizer *)ges
{
	[self becomeFirstResponder];
	UIMenuController * menu = [UIMenuController sharedMenuController];
        //尺寸和添加到哪里
	[menu setTargetRect: [self frame] inView: self.superView];
	[menu setMenuVisible: YES animated: YES];
}

重写下面方法：

//是否截获事件响应
- (BOOL)canBecomeFirstResponder
{
    return YES;
}

//什么样的操作会被响应
- (BOOL)canPerformAction:(SEL)action withSender:(id)sender
{
	return action == @selector(copy:);
}

- (void)copy:(id)sender
{
    UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];
    [pasteboard setAttributedString:@"此处是富文本，其他同理"];
}
