Description
- (CGFloat)fd_systemFittingHeightForConfiguratedCell:(UITableViewCell *)cell {
CGFloat contentViewWidth = CGRectGetWidth(self.frame);
如果self即UITableView使用代码添加约束时，第一次调用fd_systemFittingHeightForConfiguratedCell方法时UITableView宽度为0，在使用- (CGFloat)fd_heightForCellWithIdentifier:(NSString *)identifier cacheByIndexPath:(NSIndexPath *)indexPath configuration:(void (^)(id cell))configuration使用缓存高度时，如果UITableView不刷新，缓存高度不对，应改为
- (CGFloat)fd_systemFittingHeightForConfiguratedCell:(UITableViewCell *)cell {
if (self.superview) {
[self.superview layoutIfNeeded];
}
CGFloat contentViewWidth = CGRectGetWidth(self.frame);
使用layoutIfNeeded获取UITableView正确宽度
