[英]Xcode Breakpoint: shortcut for file name or class name
When setting a breakpoint in Xcode there is the %B
shortcut.在 Xcode 中设置断点时,有%B
快捷方式。 Placed into the "Log message" it will print the breakpoint name to the console.放入“日志消息”中,它将把断点名称打印到控制台。 The breakpoint name
will be the method name. breakpoint name
将是方法名称。
So creating a breakpoint in - (void)viewDidLoad
will print所以在- (void)viewDidLoad
创建断点将打印
-viewDidLoad
When the breakpoint stops all is clear.当断点停止时,一切就清楚了。 But when the app continues after evaluating just viewDidLoad
printed in the debug console won't tell which Class was called.但是当应用程序在评估调试控制台中打印的viewDidLoad
后继续运行时,不会告诉调用了哪个类。 viewDidLoad
could be in every ViewController. viewDidLoad
可以在每个 ViewController 中。 So I add the class name to identify the location (see image).所以我添加了类名来标识位置(见图)。
To avoid having to type the full class name I use initials: MGA_OneViewController
becomes OVC
为了避免输入完整的类名,我使用首字母缩写: MGA_OneViewController
变为OVC
The OVC %B
produces the output OVC %B
产生输出
OVG -viewDidLoad
and now the Class is known.现在班级是已知的。
Typing three (or a few) letters is not a problem but is does require discipline to ensure the same acronym is used through out the class.键入三个(或几个)字母不是问题,但确实需要纪律以确保在整个课程中使用相同的首字母缩略词。
I found a nice syntax but that is even longer, Craig uses p (void)NSLog(@"%s: %@", _cmd)
我发现了一个很好的语法,但它更长,Craig 使用p (void)NSLog(@"%s: %@", _cmd)
Some related SO questions ( 16661758 , 12695845 ) all use a rather long command, too long for me to remember.一些相关的 SO 问题( 16661758 、 12695845 )都使用了相当长的命令,太长了我记不清了。
So my questions are: is the there a percent shortcut for the class name?所以我的问题是:类名是否有百分比快捷方式? A Percent-F
maybe?可能是Percent-F
? Alternatively, is it possible to create a breakpoint template that will contain the expressions ready made?或者,是否可以创建一个包含现成表达式的断点模板?
我使用@[self class]@ %B
,虽然它不是格式化程序,但可能比原始问题中列出的替代方案更紧凑。
为了快速,您可以使用
@type(of:self)@
