To make this kind of loading, we can use only one label and then use Box-shadow to make a loading diagram. First, you need a label:And then the CSS: $fontSize: 30px; $radius: 2em; .Loading { font-size: $fontSize; Width:1em; Height:1em; border-radius:50%; margin:100px Auto; box-shadow:0 -2em Rgba (255, 0, 0, 1), 1.414

Final Effect Diagram: The specific steps to create are as follows: One, create a new document, 640 pixel wide, 480 pixel high, white background. Next, create a new layer, fill it with #e2e2e2, rename it to BG, right-click the BG layer in the Layers panel, and select Convert to Smart object. Then apply the filter (filter) noise (noise) add noise (add noise) command to the layer. The parameters are set as shown in the following illustration: Second, create a new layer, n

If you want to implement the above interface, it will generally show inconsistent with the expected, although we set the color is the same. The following steps can be implemented:1. Turn off the transparency of Navigationbar self. Navigationcontroller . Navigationbar . Translucent = NO ;2. Using the digital color measuring meter, the navigation bar color of the RGB, again set the navigation bar color and the following view background color.3. Remove the gray split line below the navigation ba

Let's take a look at some of the rounded-arrow rectangle's Tip box effect chart that we've seen First, understand Cgcontextref First of all need to understand the Cgcontextref, the author has the opportunity to further explain in detail, this article in a simple introduction, convenient reading comprehension. Understand the Cgcontextref coordinate system first Coordinates Example: For the mall-type app has a lot of original price, the current

Set the View to display only the transparent bottom border, transparent background box, and shadow background box. The implementation result is as follows: The following code implements an xml with a border, which is very common. The following shows only the xml of the lower border The following is the background of the s
