这个错误叫奇异矩阵,
引起的原因有三种:
1 [UIFont fontWithName:@"AFontName" size:0] 你把字体的size设置为0了
2 你添加的view控件frame为0 例如:
I was seeing this problem too when I added a UIWebView to my self.view.
The offending code was:
UIWebView *wv = [[UIWebView alloc]init];
and the solution is:
UIWebView *wv = [[UIWebView alloc]initwithFrame:[[UIScreen mainScreen]bounds]];
or any framesize except 0.0.
3. UIScrollView, storyboard , autolayout 冲突,这个好像是苹果的问题,解决方法是
uncheck the "use autolayout" checkbox on storyboard properties
4. 如果你用webview 载入网页出现这样问题的话,是因为
CSS 設定 display: inline-block 而造成 Transform 错误(估计是苹果的bug)
解決方法是:
選擇一:不要用「display: inline-block」(這應該會是 Apple 會回答你的解決方案)。
選擇一:如果你跟我一樣,使用「display: inline-block」是為了要把 Element 排成橫的,那麼恭喜!你可以改用「display: table-cell」,效果一樣!
