Hi everybody! I'm new to ios7 development and i have some questions. I'm developing for my client an app that calculate the energy savings. My web designer has provided a stack where i can see two values (in %) like in the image that i attach here. Now: i could develop this function by creating a rectangle, set it in 10 columns and color it by the value that i have. But after this, this stack could be broken at the center ..and at its place, i have to put an image. The first question is: is this animation possible? The second question: is possible to see the content of a view gradually? Like a gradient? The third question: i would like that the field that i'm building cames from the left and when i want to go to next view they go out on the right. Is this possible?
