xcode 8.3 ,ios 10.3 ,cell高度计算不准确

[yyc123]

cell布局使用xib AutoLayout, 添加的约束没问题,label没有随内容换行,控制台有约束报错信息: Unable to simultaneously satisfy constraints. Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. ( <NSLayoutConstraint:0x60800009c020 UITableViewCellContentView:0x7ff80263ff00.width == 375>, <NSLayoutConstraint:0x608000097660 UITableViewCellContentView:0x7ff80263ff00.width == 229.5> ) 求解

换成系统方法 _tableView.estimatedRowHeight = 80.0; _tableView.rowHeight = UITableViewAutomaticDimension; 就不会出现问题

@yyc123 would you mind to add a screenshot of your auto layout?

[yyc123]

[weekwood]

@yyc123 are you sure you code run on iOS 10.3, sounds like 10.2 issues.

[wws19125]

@weekwood 我是在iOS 10.3上发现问题的

[weekwood]

@wws19125 show me logs?

[wws19125]

unfortunately，I got nothing in my xcode(8.3 , debug mode) output window

[weekwood]

@wws19125 then can you describe your issue, and show me screenshot

[wws19125]

as you seeing, the height for the row is not correctly calculated here is the code

#ifndef __IPHONE_10_3
///FIXME: iOS 10.3上会出问题
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
    return [tableView fd_heightForCellWithIdentifier:@"cell" cacheByIndexPath:indexPath configuration:^(JHBaseInfoCell * cell) {
        [self cofigureCell:cell AtIndexPath:indexPath];
    }];
}
#endif

@yyc123 is right

[weekwood]

@wws19125 which version you used? 1.6.beta? and can you show me your autolayout code or xib. demo will be awesome

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger. The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful. 2017-05-05 12:44:56.406050+0800 CitySpeedLoan[9178:206278] [LayoutConstraints] Unable to simultaneously satisfy constraints.

pod 'UITableView+FDTemplateLayoutCell', '~> 1.5.beta'

[weekwood]

@licansir this issue fixed 1.6.beta, feel free to try branch 'master' too. #302

[licansir]

ok verygood

[weekwood]

@yyc123 try 1.6.beta if your issue fixed too

发现[0, 4] 这个cell在多次计算后就不准确了 xcode8.3.2 iOS10.3 pod 'UITableView+FDTemplateLayoutCell', '~> 1.6'

[liguangyi1991]

还是不准确啊@weekwood

[weekwood]

@liguangyi1991 1.6?

[liguangyi1991]

嗯,是1.6,约束什么都没有问题,只是Label的会出现比较大的内间距,感觉像是这个Label被纵向拉伸啦@weekwood

[zvving]

1.6 还是有问题，具体细节和解决方法我描述到了这里：https://github.com/forkingdog/UITableView-FDTemplateLayoutCell/issues/315

[Daren-Wang]

+1 真的计算不准

[zhengweishu]

8.0以上，系统现在已经提供了适配方法 self.tableView.estimatedRowHeight = 150; self.tableView.rowHeight = UITableViewAutomaticDimension; 计算很准确，不会出现上面的情况
