We have introduced the basic knowledge of Core Animation and the simple use of CALayer. In the end, there are still some Animation effects to be played. Here we will list several Animation effects. For more information, see this article.1. Move the image to the bottom right corner to become transparent. Use CAAnimationGroup to overlay the animation effect, which is described in "Move the image to the lower right corner and make it transparent: , The above three figures are the three States of th

database, five connection parameters are required, namely server, instance, user, password, and version. Server refers to the Host Name of the server, instance refers to the service name or port number, user is the username of the database, password database corresponds to the password of the user, version refers to a version in the enterprise Geodatabase multi-version mechanism, the default version is "SDE. default ". If the relational database is SQL Server, the database parameter is required

Secondary besell Curve This is a little more complicated than a besell curve. The characteristic of the secondary besell curve is that there is a control point. Func

do I set the width, color, and style of the line?Setting these styles is what we call the state of modifying the graphics context.Set line width: Cgcontextsetlinewidth (CTX, 20);To set the connection style for a segment: Cgcontextsetlinejoin (CTX, Kcglinejoinround);Add vertex style: Cgcontextsetlinecap (CTX, Kcglinecapround);Set the color of the line: [[Uicolor Redcolor] setstroke];5. How do I draw a curve?A special control point is required to draw a curve to determine the degree of curvature

The charge number of the battery is 300 times or more for full charge. In the case of incomplete charge, such as the meeting completed, the use of half of the electricity, connected to the external power supply, will automatically recharge, these incomplete charge on the battery life is generally not much impact, but long-term accumulation will also reduce the performance of the battery. It is recommended that the battery be fully used and then recharged. Now the E-series notebook has been
