Getting thread id of current method call
提问by Alexi Groove
Is there a way to print out the current thread id on which the current method is executing on?
有没有办法打印出当前方法正在执行的当前线程ID？
(objective-c please)
（请目标-c）

you can hack something up like this (this just prints pretty, but you can go ahead and split until you get the number):
你可以像这样修改一些东西（这只是打印得很漂亮，但你可以继续拆分直到你得到数字）：
+ (NSString *)getPrettyCurrentThreadDescription {
NSString *raw = [NSString stringWithFormat:@"%@", [NSThread currentThread]];
NSArray *firstSplit = [raw componentsSeparatedByCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"{"]];
if ([firstSplit count] > 1) {
NSArray *secondSplit = [firstSplit[1] componentsSeparatedByCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"}"]];
if ([secondSplit count] > 0) {
NSString *numberAndName = secondSplit[0];
return numberAndName;
}
}
return raw;
}
