Objective-C基础语法之NSRunLoop

不进行讲解，直接上代码。

#import <Foundation/Foundation.h>

@interface Demo01 : NSObject


-(void) run;
-(void) start;

@end

#import "Demo01.h"

@implementation Demo01

-(void) run
{
    static int counter = 0;
    
    while(![[NSThread currentThread]isCancelled]){
        [NSThread sleepForTimeInterval:1];
        NSLog(@"当前数值：%i",counter++);
    }
    
}

-(void) start
{
    [NSThread detachNewThreadSelector:@selector(run) toTarget:self withObject:nil];
}

@end

#import <Foundation/Foundation.h>
#import "Demo01.h"

int main(int argc, const char * argv[])
{

    @autoreleasepool {
        
        // insert code here...
        NSLog(@"Hello, World!");
        
        [[[Demo01 alloc] init]start];
        
        while (YES) {
            
            [[NSRunLoop currentRunLoop]runMode:NSDefaultRunLoopMode beforeDate:[NSDate distantFuture]];
        }
        
    }
    return 0;
}
