NSURLConnection+Swizzled

该分类用于“记录 curl 命令行提示，以进行调试”。该分类受到了 Mugunth Kumar 的 NSMutableURLRequest+MKCurlAdditions 的启发，您可以在Mugunth Kumar处找到它，您可以在这里找到它这里。它还会打印堆栈跟踪，以便您了解调用来源。

这对于了解调用的类型以及它们是如何创建的非常有用，例如，您的 URL 是如何创建的。

不要忘了在生产代码中禁用它。这只是为了调试

需求

包含库

• libobjc.dylib

并可导入您希望使用的分类

• #import "NSURLConnection+Swizzled.h"

将 NSURLConnection+Swizzled 添加到项目中

只需将这两个文件添加到您的项目中（NSURLConnection+Swizzled.h 和 NSURLConnection+Swizzled.m）。

使用方法

在建立远程连接之前，您可以调用 SWIZZ_IT，在完成后调用 UN_SWIZZ_IT。例如

SWIZZ_IT
[NSURLConnection sendAsynchronousRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"www.google.com"]] queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse *as, NSData *a, NSError *ads)
{
   NSLog(@"blah blah");
}];

UN_SWIZZ_IT

这将输出

curl -X GET 'www.google.com'

如果您对堆栈跟踪不满，请勿使用： STOP_STACKTRACE_SWIZZ。

如果您希望在应用程序整个运行期间接收信息，则在 applicationDidFinishLaunching 上调用 SWIZZ_IT，并不要使用 UN_SWIZZ_IT。
