我创建了如下所示的内容，红色视图是此行代码import cv2
import numpy as np
x_mouse, y_mouse = (None, None)
def draw_rectangle(event, x, y, flags, param):
global x_mouse, y_mouse
if event == cv2.EVENT_LBUTTONDOWN:
cv2.rectangle(img, pt1=(x, y),
pt2=(x+10, y+10),
color=(180, 105, 255),
thickness=4)
cv2.imshow('my_drawing', img)
cv2.waitKey(0)
x_mouse, y_mouse = x, y
cv2.namedWindow(winname='my_drawing', flags=cv2.WINDOW_NORMAL)
cv2.resizeWindow(winname='my_drawing', width=600, height=600)
cv2.setMouseCallback('my_drawing', draw_rectangle)
img = np.zeros((600, 600, 3), np.uint8)
while True:
cv2.imshow('my_drawing', img)
k = cv2.waitKey(10) & 0xFF
if k == 27:
break
elif k == ord('s'):
print("x, y = ({}, {})".format(x_mouse, y_mouse))
cv2.destroyAllWindows()
创建的TabBarController的子视图
当我尝试在红色视图中添加按钮时，它们不会响应我的轻按，而是后面的ViewController（带有tabBar.insertSubview(redView, aboveSubview: tabBar)的那个）响应了我的手势
我已经在红色视图中设置了imageCollecitonView。有什么想法吗？
