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 properties4. 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！参考: http://stackoverflow.com/questions/7471027/overriding-layoutsubviews-causes-cgaffinetransforminvert-singular-matrix-ranhttp://firchtsai.blogspot.com/2013/02/ios-cgaffinetransforminvert-singular.htmlhttp://stackoverflow.com/questions/7471027/overriding-layoutsubviews-causes-cgaffinetransforminvert-singular-matrix-randown
