ios开发之----复制和粘贴

摘要:UIPasteboard有系统级别和应用级别两种类型，所以不仅可以在应用程序内通信，还能在应用程序间通信，比如我复制一个url，然后打开safari，粘贴到地址栏去，而我们可以在应用程序间通信、共享数据。

全局使用

    //系统级别
    UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];
    pasteboard.string = self.pTextField.text;
    NSLog(@"\r\n====>输入框内容为:%@\r\n====>剪切板内容为:%@",self.pTextField.text,pasteboard.string);

内部使用--copy

    //应用内单独使用时
    NSString * strBuildID = [[[NSBundle mainBundle]infoDictionary]objectForKey:@"CFBundleIdentifier"];
    UIPasteboard * myPasteboard = [UIPasteboard pasteboardWithName:strBuildID create:YES];
    myPasteboard.string = @"复制测试数据";        

内部使用--paste

    NSString * strBuildID = [[[NSBundle mainBundle]infoDictionary]objectForKey:@"CFBundleIdentifier"];
    UIPasteboard * myPasteboard = [UIPasteboard pasteboardWithName:strBuildID create:NO];
    self.pLabel.text = myPasteboard.string;
