• 背景故事:
  項目中涉及到一個html的頁面.
  wkwebview加載的web頁面.
  需要
  “在web中點擊返回主頁按鈕時,返回到原生主頁,而非web主頁”

2018年一月2號的我還不懂html5和h5與原生的交互.

嘗試了很多方法....首先,html5 網(wǎng)站的代碼是不能改的...javascript也沒有預(yù)留和ios交互的接口...里面的頁面轉(zhuǎn)換也不能用wkwebview的delegate攔截到...

于是想了一個我自己感覺有點笨的方法...

思路是用UITouch來控制webview的點擊事件,每次點擊之后過0.5s(留出頁面轉(zhuǎn)換的事件)去獲取當(dāng)前的url,如果url是web主頁的url就返回到原生主頁..

代碼如下:
先創(chuàng)建一個名為CustomWKWebView的子類,.h文件如下

- (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event {
    
    static UIEvent *e = nil;
    
    if (e != nil && e == event) {
        e = nil;
        return [super hitTest:point withEvent:event];
    }
    
    e = event;
    
    if (event.type == UIEventTypeTouches) {
        NSSet *touches = [event touchesForView:self];
        UITouch *touch = [touches anyObject];
        if (touch.phase == UITouchPhaseBegan) {
            NSLog(@"Touches began");
            NSLog(@"%@",self.URL.absoluteString);
            [self performSelector:@selector(delayMethod)
                       withObject:nil
                       afterDelay:0.5f];
            
        }else if(touch.phase == UITouchPhaseEnded){
            NSLog(@"Touches Ended");
            
        }else if(touch.phase == UITouchPhaseCancelled){
            NSLog(@"Touches Cancelled");
            
        }else if (touch.phase == UITouchPhaseMoved){
            NSLog(@"Touches Moved");
            
        }
    }
    return [super hitTest:point withEvent:event];
}

-(void)delayMethod
{
    NSLog(@"%@",self.URL.absoluteString);
    if ([self.URL.absoluteString isEqualToString:@"主頁的url"]) {
        [[NSNotificationCenter defaultCenter] postNotificationName:@"wkwebview-backtohome" object:nil];
    }

}
