IOS開發之文本複製

原始地址：IOS開發之文本複製

本文基於富文本:DTCoreText

#import <Foundation/Foundation.h>#import <MobileCoreServices/UTCoreTypes.h>//添加此架構@interface UIPasteboard (AttributedString)- (void) setAttributedString:(NSAttributedString *)attributedString;@end

#import "UIPasteboard+AttributedString.h"@implementation UIPasteboard (AttributedString)- (void) setAttributedString:(NSAttributedString *)attributedString{//\ufffc為對象預留位置，目的是當富文本中有映像時，只複製文本資訊！！！NSString *htmlString = [[attributedString string] stringByReplacingOccurrencesOfString:@"\ufffc" withString:@""];NSMutableDictionary *item = [NSMutableDictionary dictionaryWithCapacity:1];[item setValue:htmlString forKey:(NSString *)kUTTypeText];self.items = [NSArray arrayWithObject:item];}@end

給要複製的視圖添加長按事件：

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];        //尺寸和添加到哪裡[menu setTargetRect: [self frame] inView: self.superView];[menu setMenuVisible: YES animated: YES];}

重寫下面方法：

//是否截獲事件響應- (BOOL)canBecomeFirstResponder{    return YES;}//什麼樣的操作會被響應- (BOOL)canPerformAction:(SEL)action withSender:(id)sender{return action == @selector(copy:);}- (void)copy:(id)sender{    UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];    [pasteboard setAttributedString:@"此處是富文本，其他同理"];}
