Some pitfalls of AutoLayout: AutoLayout

Some pitfalls of AutoLayout: AutoLayout

1. Add constraints to a UIView. If you want it to be displayed at the bottom of the UITableView, but it is not displayed, it will appear at the top of the UITableView.

Error code:

1 [self. tableView addSubview: self. adjustView]; 2 3 [self. adjustView mas_makeConstraints: ^ (MASConstraintMaker * make) {4 make. left. right. bottom. similar to (self. talbeview); 5 make. height. similar to (@ 126); 6 7}];

 

 

This may be caused by the scrolling of UITableView, which is consistent with that of UIScrollView.

Solution:

1 [self. view addSubview: self. adjustView]; 2 3 [self. adjustView mas_makeConstraints: ^ (MASConstraintMaker * make) {4 make. left. right. bottom. similar to (self. view); 5 make. height. similar to (@ 126); 6 7}];

It can be displayed at the bottom of self. view.
