Objective c 如何通过NSThread传递参数

我以前从未使用过NSThread，我想知道是否可以将参数传递给它，如果可以，如何传递？例如：

NSObject *phrase = @"I JUST MADE IT THROUGH TO THE THREAD METHOD!"; 

[NSThread detachNewThreadSelector:@selector (run_thread)
                         toTarget:self 
                       withObject:phrase];

然后

我想你明白我想做什么了。有什么建议吗？

你就快到了：

NSObject *phrase = @"I JUST MADE IT THROUGH TO THE THREAD METHOD!"; 

[NSThread detachNewThreadSelector:@selector (run_thread:) // have to add colon
                     toTarget:self 
                   withObject:phrase];

-(void)run_thread:(NSObject* )phrase // change method signature to support taking an NSObject 
{
  NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; 

  NSLog(@"RECORD FILE PATH ---->   %@", phrase);

  [pool drain];

}

NSObject *phrase = @"I JUST MADE IT THROUGH TO THE THREAD METHOD!"; 

[NSThread detachNewThreadSelector:@selector (run_thread:) // have to add colon
                     toTarget:self 
                   withObject:phrase];

-(void)run_thread:(NSObject* )phrase // change method signature to support taking an NSObject 
{
  NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; 

  NSLog(@"RECORD FILE PATH ---->   %@", phrase);

  [pool drain];

}

[NSThread detachNewThreadSelector:@selector(run_thread:)
                         toTarget:self 
                       withObject:phrase];

-(void)run_thread:(NSString *)phrase
{
    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; 

    NSLog(@"RECORD FILE PATH ---->   %@", phrase);

    [pool drain];
}
