Question

在XCode中调试程序时，我有几个CFStringRef变量指向长度大约为200个字符的字符串。

在调试器中，它只显示这些字符串的值达到一定长度，然后将它们省略。我真的很想看到字符串的全部价值。

我可以配置一些选项，以便它不会以任意长度终止它们吗？

Answer 1

在调试控制台中，您可以通过执行以下操作来获取字符串值：

(gdb) print (void)CFShow(myCFString)

或：

(gdb) po (NSString*)myCFString



Either of those will display the entire string's contents to the debugging console. It's probably the easiest way to deal with large, variable-length strings or data structures of any kind.

For more information, the print command in the debugger basically dumps some data structure to the console. You can also call any functions or whatever, but since print doesn't have access to the function declarations, you have to make sure you provide them implicitly (as shown in the example above), or the print command will complain.

po is a shortcut for print-object and is the same as print except for Objective-C objects. It basically functions like this:


  (gdb) print (const char *)[[theObject debugDescription] UTF8String]



This is really useful for examining things like NSData object and NSArray/NSDictionary objects.

print命令。

要显示非常长的字符串，请使用print long string in xcode 6 debugging console

中的方法

在lldb控制台中，增加 max-string-summary-length

setting set target.max-string-summary-length 10000

使用print或po命令打印字符串

print my_string

Answer 3

如果您在xcode中编译c ++项目，请使用此命令

po string_name

XCode调试器：显示长字符串
