我在尝试创建 UIImageView 时出错.看这段代码:
I have an error when I tried to create a UIImageView. Look at this code :
UIImage* backgroundPanel = [[UIImage imageNamed:@"loginPanelBackground.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(90, 0, 149, 416)];
self.connexionBackgroundImgView = [[UIImageView alloc] initWithImage:backgroundPanel];
self.connexionBackgroundImgView.frame = CGRectMake(0, 0, 416, 390); // THIS LINE PROVOC THE INVALID CONTEXT
[self.connexionView insertSubview:self.connexionBackgroundImgView aboveSubview:self.connexionToCreationCompteView];
它在日志中抛出这个错误:

我只在 iPad 上遇到过这个错误，在模拟器上没有，我不明白..:/
I had this error only on the iPad, not with the Simulator, I don't understand.. :/
