Mac下网速模拟及视图点击事件处理-优快云博客

本文介绍了如何在Mac系统中使用ipfw工具进行网络带宽的模拟限制，包括设置上传和下载速度的方法。此外还提供了一个解决子视图超出父视图时点击事件无法响应的问题的代码实现。

1. 模拟器网速调整：
限制时输入下面两行，根据需要修改下面的数字：
sudo ipfw pipe 1 config bw 350kbit/s plr 0.05 delay 10000ms;
sudo ipfw add pipe 1 dst-port http
不想再去限制网速是，输入下面的命令行:
sudo ipfw flush
1.2 mac下限制网速：
Advanced OS X users know that Darwin comes with ipfw, which can be used to set up a custom firewall. This same service however can be used to also limit bandwidth on specific ports.
Example:sudo ipfw pipe 1 config bw 15KByte/screates a pipe that only allows up to 15KB/s to go through.
Then:sudo ipfw add 1 pipe 1 src-port 80will attach that pipe to the outgoing traffic on port 80, effectively limiting the outgoing traffic of the web server.sudo ipfw delete 1will remove the pipe from the port.
[kirkmc adds: I haven't tested this. Just make sure you remember to turn this off when you no longer need it!]

2. 子视图超出父视图部分仍然响应点击事件的处理
- (UIView*)hitTest:(CGPoint)point withEvent:(UIEvent *)event
{
UIView *view = [super hitTest:point withEvent:event];
for (UIView *subview in self.subviews) {
if (view != nil &&view.userInteractionEnabled)
break;
CGPoint newPoint = [self convertPoint:point toView:subview];
view = [subview hitTest:newPoint withEvent:event];
}
return view;
}
