Objective-C基礎文法之NSRunLoop

不進行講解，直接上代碼。

1 #import <Foundation/Foundation.h>2 3 @interface Demo01 : NSObject4 5 6 -(void) run;7 -(void) start;8 9 @end

 1 #import "Demo01.h" 2  3 @implementation Demo01 4  5 -(void) run 6 { 7     static int counter = 0; 8      9     while(![[NSThread currentThread]isCancelled]){10         [NSThread sleepForTimeInterval:1];11         NSLog(@"當前數值：%i",counter++);12     }13     14 }15 16 -(void) start17 {18     [NSThread detachNewThreadSelector:@selector(run) toTarget:self withObject:nil];19 }20 21 @end
