일 주일간 대단한 성과! 여러 페이지에 마우스 이벤트 및 사용자 입력을 저장하려는 경우 다른 모든 대답은 올바르지 않습니다.
1) Swizzle 방법 ( rentzsch / jrswizzle 라이브러리 사용) :
[NSClassFromString(@"UIWebDocumentView") jr_swizzleMethod:@selector(canPerformAction:withSender:) withMethod:@selector(myCanPerformAction:withSender:) error:nil];
NSObject + myCanPerformAction.h :
@interface NSObject (myCanPerformAction)
- (BOOL)myCanPerformAction:(SEL)action withSender:(id)sender;
@end
NSObject + myCanPerformAction.m :
#import "NSObject+myCanPerformAction.h"
@implementation NSObject (myCanPerformAction)
- (BOOL)myCanPerformAction:(SEL)action withSender:(id)sender {
if (action == @selector(copy:)) {
return [self myCanPerformAction:action withSender:sender];
}
if (action == @selector(paste:)) {
return [self myCanPerformAction:action withSender:sender];
}
return NO;
}
@end
2) UIView에 UIWebView를 놓고 코드를 추가하십시오.
UITapGestureRecognizer* singleTap = [[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap:)] autorelease];
singleTap.numberOfTapsRequired = 2;
singleTap.numberOfTouchesRequired = 1;
singleTap.delegate = self;
[self.view addGestureRecognizer:singleTap];
그리고 이것:
- (void)handleSingleTap:(UIGestureRecognizer*)gestureRecognizer {
return;
}
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer {
if ([otherGestureRecognizer isKindOfClass:[UITapGestureRecognizer class]]) {
UITapGestureRecognizer *gesture = (UITapGestureRecognizer *)otherGestureRecognizer;
if (gesture.numberOfTapsRequired == 2) {
[otherGestureRecognizer.view removeGestureRecognizer:otherGestureRecognizer];
}
}
return YES;
}
