UITableView reloadRowsAtIndexPaths graphical glitch

由 谁都会走 提交于 2019-12-01 00:09:42
问题 If I call reloadRowsAtIndexPaths for the first cell of a section, with previous section empty and the one above not-empty, I get a strange animation glitch (even if I specify "UITableViewRowAnimationNone") where the reloaded cell slides down from the above section..

Prevent Splash Screen from showing after returning from background

由 天涯浪子 提交于 2019-11-29 03:45:25
