需要让一个view支持点击
［解决过程］
1.搜：
swift uiview click
参考：
后来用：
let tapRecog = UITapGestureRecognizer(target: self, action: "clickFileHandler:")
self.messageTableView.addGestureRecognizer(tapRecog)
func clickFileHandler(gestureReconizer:UITapGestureRecognizer){
// print("gestureReconizer=\(gestureReconizer)")
// print("gestureReconizer.state=\(gestureReconizer.state)")
if gestureReconizer.state == UIGestureRecognizerState.Ended {
let curPoint:CGPoint = gestureReconizer.locationInView(self.messageTableView)
if let indexPath = self.messageTableView.indexPathForRowAtPoint(curPoint) {
if let curCell = self.messageTableView.cellForRowAtIndexPath(indexPath) {
let curMessageTVC:MessageTableViewCell = curCell as! MessageTableViewCell
let convertedPointToView = self.messageTableView.convertPoint(curPoint, toView: curMessageTVC)
let pointInCurCell:CGPoint = convertedPointToView
if curMessageTVC.message is ResourceMessage {
if (CGRectContainsPoint((curMessageTVC.fileBubbleView?.frame)!, pointInCurCell)) {
let notSupportViewAlertCtrl = UIAlertController(title: "友情提醒", message: "手机上暂时不支持查看该文件，请去web端查看", preferredStyle: UIAlertControllerStyle.Alert)
let sureAlertAction = UIAlertAction(title: "确定", style: UIAlertActionStyle.Destructive, handler: nil)
notSupportViewAlertCtrl.addAction(sureAlertAction)
self.presentViewController(notSupportViewAlertCtrl, animated: true, completion: nil)
}
}
}
}
}
}即可。
效果是：
点击文件：
弹出提醒：
［总结］
让UIView视图支持点击的话，核心代码就只是：
let tapRecog = UITapGestureRecognizer(target: self, action: "clickFileHandler:")
self.messageTableView.addGestureRecognizer(tapRecog)
func clickFileHandler(gestureReconizer:UITapGestureRecognizer){
//...
