NSThread基础使用

NSThread *thread = [[NSThread alloc] initWithTarget:self selector:@selector(run) object:nil];
[thread start];

1 + (NSThread *)mainThread;
2 - (BOOL)isMainThread;
3 + (BOOL)isMainThread;

1 NSThread *current = [NSThread currentThread];

1 + (double)threadPriority;
2 + (BOOL)setThreadPriority:(double)p;
3 - (double)threadPriority;
4 - (BOOL)setThreadPriority:(double)p;

1 - (void) setName:(NSString *)n;
2 - (NSString *)name;

1 [NSThread detachNewThreadSelector:@selector(run) toTarget:self withObject:nil];

1 [self performSelectorInBackground:@selector(run) withObject:nil];

1 - (void)start;

1 + (void)sleepUntilDate:(NSDate *)date;
2 + (void)sleepForTimeInterval:(NSTimeInterval)ti;

1 + (void)exit;

1 @property (assign, atomic) int age;
2 - (void)setAge:(int)age
3 {
4 @synchronized(self) {
5 　　　　_age = age;
6 　　}
7 }

1 - (void)performSelectorOnMainThread:(SEL)aSelector withObject:(id)arg waitUntilDone:(BOOL)wait;
2 - (void)performSelector:(SEL)aSelector onThread:(NSThread *)thr withObject:(id)arg waitUntilDone:(BOOL)wait;
