纠结了几天的小问题分享下：         1. 截取UIWebView缩略图办法         //webBrowser为UIWebViw对象         UIGraphicsBeginImageContext(webBrowser.frame.size);         CGContextRef context = UIGraphicsGetCurrentContext();

object-c 部分

swift and oc 1. swift通过括号初始化属性，oc通过alloc init方式初始化.     SWIFT     let myTableView: UITableView = UITableView(frame: CGRectZero, style: .Grouped)     OBJECTIVE-C     UITableView *myTableVi

I eventually solved the problem by quitting Xcode, emptying out the ~/Library/Developer/Xcode/DerivedData folder, and then reopening the project
