iOS开发模拟限速

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：

sudoipfwpipe1configbw350kbit/splr0.05delay10000ms;

sudoipfwaddpipe1dst-porthttp

不想再去限制网速是，输入下面的命令行:

sudoipfwflush

1.2mac下限制网速：

AdvancedOSXusersknowthatDarwincomeswithipfw,whichcanbeusedtosetupacustomfirewall.Thissameservicehowevercanbeusedtoalsolimitbandwidthonspecificports.

Example:sudoipfwpipe1configbw15KByte/screatesapipethatonlyallowsupto15KB/stogothrough.

Then:sudoipfwadd1pipe1src-port80willattachthatpipetotheoutgoingtrafficonport80,effectivelylimitingtheoutgoingtrafficofthewebserver.sudoipfwdelete1willremovethepipefromtheport.

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)pointwithEvent:(UIEvent*)event

{

UIView*view=[superhitTest:pointwithEvent:event];

for(UIView*subviewinself.subviews){

if(view!=nil&&view.userInteractionEnabled)

break;

CGPointnewPoint=[selfconvertPoint:pointtoView:subview];

view=[subviewhitTest:newPointwithEvent:event];

}

returnview;

}
