1. FrameEach view has a frame property, which is a cgrect structure that describes the position of the rectangle where the view resides in its parent view .(The default origin of the screen coordinate system is in the upper-left corner, the x-axis stretches to the right, and the y-axis stretches down).Sets the frame normally through the specified initializer of the view initWithFrameLet's take a look at an example that initializes 3 rectangular regions that overlap each other.(OBJECTIVE-C code)

Before talking about this, we will first introduce another concept, DCE (Data Communication Equipment) speed. It refers to the transmission speed between two modem devices, that is, between telephone lines. We call 56k the speed. DTE (data terminal equipment) refers to the transmission speed from the local computer to the modem. If the telephone line transmission rate (DCE speed) is 56000bps, after receiving the data, the modem decompress 56000 × 4 = 115200bps according to the v.42 bis protocol,

with WIFI, but it needs to use the RTS/CTS protocol to solve the conflict problem. The UDF/OFDM protocol is a hybrid modulation method that is optional for the 802.11g protocol. The signal header and the leading signal are transmitted in the modulation mode using the Supplementary Code-keying (ASR), and the load is transmitted using the OFDM technology. Because the OFDM technology is separated from the content of the content. Therefore, the conversio

1. Challenges faced by MacRF Link Quality802.11 adopt a positive confirmation mechanism. All transmitted frames must be responded to, as long as any one link fails, the frame is considered a loss. -------Atomic operationproblems with hidden nodesWireless transceivers typically have a half-duplex operation, which means they cannot send and receive data at the same time. Use RTS and CTS signals to clear the transfer area. RTS frames have two purposes: t

. This time, the perfect upgrade is almost equal to rewriting. Avoiding this tragedy is very simple: After completing the development task, use CTS to test compliance with the non-compliant Android compatibility specification. If all pass so OK thank goodness, if there are fail (does not affect system compilation and related functions to achieve, just do not conform to the compatibility specification), it is necessary to check the relevant documents i

should be careful to convert the array to the appropriate object when inserting values.For example: To insert an integer 1 o'clock, do not call V1.addelement (1) directly, the correct method is:Vector v1 = new vector ();Integer integer1 = new Integer (1);V1.addelement (Integer1);(2) Public final synchronized void Setelementat (Object obj,int index)The object at

The following points need to be clarified:1. The local front-end debug code must be to call the original path and code, but the line must be run by another path after the package, which is the generated Dist folder.2.requirejs Introduction, how to control the path below the line? We have this control, the code is as follows:src= "${resource}/js/base/require.js" data-main= "${resource}/js /accountmain ">script>This ${resource} is the service-side control passed to the page, the value of local de
