iOS开发细节记录汇总
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 = ; for (UIView *subview in self.subviews) { if (view != nil &&view.userInteractionEnabled) break; CGPoint newPoint = ; view = ; } return view;}
