searching for the hit-test view is called Hit-Testing. Then, how does the system execute Hit-Testing? First, assume that there is now such a UI layout, one with five views of ABCDE. If A click event occurs in View D, the system first searches for View A at the top level and finds that the event is in View A or its subclass, then, locate B and C and find that the event is in C or its subclass. Then, search for it in C. Then, find that the event is in D and D has no subclass, the hit-test view i

Ice is a comprehensive application of the aboveAgreement to make it work in the most appropriate circumstances, to make up for the inherent defects arising from the independent use of any of them. ForFor sip, ice only needs to define some additional attributes of

After setting the first responder of the keyboard, you can click TextField to summon the keyboardThe first responder method for setting the keyboard is:[TextField Becomefirstresponder]; //At this time, the TextField input box is the first responder of the current keyboard, so only TextField lose the first responder

Both Java and C # implement the event source-event responder mechanism, but not exactly the same. Java implements two-level entity object Methods: Event source and event responder. The event responder here is also the event listener, C # implements a three-level object method for event source-proxy-event responder. The

specified time interval. In practice, this process works well, but there are some scenarios in which the CRL mechanism may be flawed: More and more revocation means that the CRL list is only getting longer, and each client must get the entire list of serial numbers There is no certificate revocation instant notification mechanism-if the certificate is revoked during client caching, the client will assume that the certificate is valid until the cache expires. Online Certificate

. Wildcard certificates (wildcardcertificates) have their application scenarios, but should be avoided, as the use of the words implies exposure to many people. In other words, fewer people can access the private key the better. 1.4 obtain a certificate from a trusted CA Choose a reliable CA (certificateauthority) that treats security more seriously, and consider the following factors in choosing a CA:* attitude towards safety Most CAS will have regular security audits, but some will be more c

The new version replaces the old version and retains the data stored on the device, provided that the package ID number must match.Certificate verificationWhen the application is enabled on the device for the first time, it is verified by assigning a certificate to the Apple OCSP se

In the previous article, the experimental environment was built. The protocol analysis can be performed once the IKE/IPSEC protocol is fully run and the relevant output and capture packets are collected. During the analysis, we will use the output of the IKE process and the Wireshark grab packet, combined with the relevant RFC, using Python to verify the calculation. First look at the full operation of the Protocol (filtering out irrelevant messages, such as)The following is a specification desc

The server provides remote services. The main logic is as follows: Code To expose servicesServer = rpc. getserver (protocol, instance, address: Port, numhandlers );Server.

running of the application. Note:The running cycle monitors the Input Source of the specified execution thread. When the input source has data to be processed, the running loop will wake up the corresponding thread and give control to the processor code of the Input Source. After the processor completes the task, it returns the control to the running loop. Then, the running loop processes the next event. If there are no other events, running the loop will bring the thread into sleep state. You
