快過年了,最近要上線系統(tǒng),本來開開心心的 都沒什么問題了,結果上線前測試大哥用他專業(yè)變態(tài)的妓術手段,測出了這個之前被忽略的問題.

經過是這樣的:
UITextField 在切換iOS系統(tǒng)手寫輸入時會出現(xiàn)crash問題,測試機系統(tǒng)版本9.3.1

Xcode調試
崩潰斷點停在IQKeyboardManager文件中

顯示崩潰原因是

-[UIKBBlurredKeyView candidateList]: unrecognized selector sent to instance 0x13fdca4a0

crash原因:
鍵盤上的手勢和View上的手勢沖突了

解決方法:
創(chuàng)建一個UIScrollView的category添加已下方法

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    if (![self isMemberOfClass:[UIScrollView class]]) {
        
    } else {
        [[self nextResponder] touchesBegan:touches withEvent:event];
        if ([super respondsToSelector:@selector(touchesBegan:withEvent:)]) {
            [super touchesBegan:touches withEvent:event];
        }
    }
    
}
-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
    if (![self isMemberOfClass:[UIScrollView class]]) {
        
    } else {
        [[self nextResponder] touchesMoved:touches withEvent:event];
        if ([super respondsToSelector:@selector(touchesBegan:withEvent:)]) {
            [super touchesMoved:touches withEvent:event];
        }
    }
    
}

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
    if (![self isMemberOfClass:[UIScrollView class]]) {
        
    } else {
        [[self nextResponder] touchesEnded:touches withEvent:event];
        if ([super respondsToSelector:@selector(touchesBegan:withEvent:)]) {
            [super touchesEnded:touches withEvent:event];
        }
    }
}
