Preface
The usual way to monitor headphone plug in iOS is to use the headset provided by the iOS system to notify event avaudiosessionroutechangenotification. The code structure is the following system notification method
Add observation message
[[Nsnotificationcenter Defaultcenter] addobserver:self selector: @selector (audioroutechangelistenercallback:) Name:avaudiosessionroutechangenotification Object:nil];
Implement the Listening method

, but not all devices in the Kinectsensor collection can be used directly, so the Kinectsensor object has a status property, an enumeration type that identifies the status of the current Kinect device. The status of the sensor and its meaning are listed in the following table:
The Kinectsensor object can be initialized only if the device is in connected state. The state of the sensor may change during the entire lifecycle of the application, which means that the application we develop must mo

So install Ubuntu black screen, you should remember to break the network, this network is not said you do not have the Internet can be, be sure to put your network cable unplugged, wireless off, and then installed on it.So summarize the f
U disk, although belong to plug and Play devices, support hot plug, but this does not mean that can be arbitrarily unplugged, if unplugged improperly, there may be damage to the U disk, causing unnecessary losses. That pull a U disk to pay attention to what problems? After summing up, there are probably the following 3 aspects.
Note: After inserting a U disk, do not pull out immediately. In particular, do
switch is turned on, then the MAC OS x system will know that a headset is plugged in, so the built-in speaker off, from the headset output sound signal, after the headset unplugged, switch automatically closed.
Careful users can find changes in the system, see the following figure, insert headphones and the sound changes in the system when the headset is not plugged in:
And one of the following is clear.
The problem is:
What do you do with the Thunder?
1, when the Thunder, we play the computer, we should immediately turn off the computer, and the Power plug unplugged, the network cable also pulled the safest.
2, even if the computer is not open, you should check the computer's power plug is unplugged, and then unplug the network cable, so that it is completely safe.
Question Answer:
Can be very responsible to tell you
Although the U disk is a Plug and Play device, support hot-swappable, but this does not mean that it can be arbitrarily unplugged, if unplugged improperly, it may cause the U disk damage, causing unnecessary losses. What problems should you pay attention to when you plug the USB stick? After summing up, there are about 3 aspects of the following.
Note: After inserting a USB stick, do not unplug it immediat
One, the CMOS parameter is lost
After booting the prompt "CMOS Battery State Low", can sometimes start, use a period of time after the crash, this phenomenon is mostly caused by insufficient CMOS power supply. For different CMOS power supply modes, different measures are taken:
1. Welding battery: Re-weld a new battery with a soldering iron.
2. Coin-cell battery: direct replacement.
3. Chip: Replace this chip preferably with the same type of chip replacement. If the battery after the replace

that one style is superior to another. In the targeted design, the design to solve the problem is the most important, as to the use of the visual language, should first depend on the product to achieve the purpose, rather than the current popular design style. Take IOS6 and IOS7 's "return" as an example--
IOS6 's return is visually more like a "push" button, illustrating the return operation area by using shadows, high light, and gradients closer to the real-world worldview, givin

Here, we choose the second way and the best choice on the platform where the device is split. You have a software renderer and want to fit the game to any resolution screen. This method is very suitable for simulator games, arcade games, simple shooting games and so on. It is good at all kinds of low-end,
