Using coreanimation in instruments to analyze animations

Using coreanimation in instruments to analyze animations

1. Open the coreanimation in instruments

2. Pre-run preparation work

Be careful to check the following options for easy commissioning

3. Operation and Commissioning

Some details to keep in mind:

1. If the screen has more than 50% of the area is composed of a translucent layer overlay, if you perform a sliding operation, it is likely to lead to the Dayton.

2. Load the picture try not to perform a zoom operation, and scaling consumes extra performance. For example, if you load a picture on the network, try loading pictures of the size of the picture instead of zooming in on the larger picture.
