如何在其他线程中打印主线程的回溯

Question

如何在其他线程中打印主线程的回追溯？

而在其他线程中，我想打印主 thread.is 的回追溯是否有任何桑普尔代码？

Answer 1

执行以下操作：

dispatch_async(dispatch_get_main_queue(), ^{
   NSLog(@"Trace = %@", [NSThread callStackSymbols]);
});

Answer 2

检查此代码：BSBacktraceLogger

+ (NSString *)bs_backtraceOfCurrentThread {
    return [self bs_backtraceOfNSThread:[NSThread currentThread]];
}
+ (NSString *)bs_backtraceOfMainThread {
    return [self bs_backtraceOfNSThread:[NSThread mainThread]];
}
