objective-c 多线程

NSThread 为objective-c 的多线程对象

#import "Saler.h"

@implementation Saler

-(Saler*) init{
    self = [super init];
    NSLog(@"init saler");
    self.ticket = [NSNumber numberWithInt:20];
    return self;
}

-(void) startSale{
    NSThread *thread = [NSThread new];
    self->thread = thread;
    [thread initWithTarget:self selector:@selector(run) object:nil];
//该访问指明调用self.run 方法作为线程运行代码 
    [thread start];
}

-(void) run{
    NSLog(@"running");
}

@end

main 函数

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

int main(int argc, const char * argv[]) {
    @autoreleasepool {
        Saler* saler1 = [Saler new];
        Saler* saler2 = [Saler new];
        [saler1 startSale];
        [saler2 startSale];
        NSLog(@"starting");
    }
