我需要做一个反向裁剪我需要让那个instad裁剪填充蒙版裁剪面具的非填充区域,我不知道是否有可能,任何想法?
谢谢
我需要在按下UIButton时打开一个ViewController,为此我使用以下代码:
NSString * storyboardName = @"Main";
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:storyboardName bundle: nil];
UIViewController * vc = [storyboard instantiateViewControllerWithIdentifier:@"ViewController"];
[self presentViewController:vc animated:YES completion:nil];
Run Code Online (Sandbox Code Playgroud)
当它采取最后一行
[self presentViewController:vc animated:YES completion:nil];
Run Code Online (Sandbox Code Playgroud)
它给我以下错误:
- [UIView setShowsFPS:]:无法识别的选择器发送到实例0x9bd5610 2013-07-16 14:40:52.728 ChainZoo [3026:a0b] *由于未捕获的异常'NSInvalidArgumentException'终止应用程序,原因:' - [UIView setShowsFPS:]:无法识别的选择器发送到实例0x9bd5610'
谁知道错误?提前致谢!!
