IOS将相同但不同的对象设置为一个内存地址

@interface ClassWithTimer : NSObject {
}
-(void) startTimer;
-(void) stopTimer;
@end
@implementation ClassWithTimer
NSTimer *up;
-(void) startTimer{
up = [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(doSomething) userInfo:nil repeats:YES];
-(void) stopTimer{
[up invalidate];
}
- (void) doSomething{}
@end
- (IBAction)startTimers:(id)sender {
timer1 = [[ClassWithTimer alloc] initWithName:@\"time1\"];
timer2 = [[ClassWithTimer alloc] initWithName:@\"time2\"];
[timer1 startTimer];
[timer2 startTimer];
[timer1 stopTimer];
[timer2 stopTimer];

进入接口块内的.h文件。览幕堤分
@interface ClassWithTimer : NSObject { NSTimer *up; //Declare iVar(instance variables) here } -(void) startTimer; -(void) stopTimer; @end @implementation ClassWithTimer -(void) startTimer{ [up invalidate]; [up release]; up = [[NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(doSomething) userInfo:nil repeats:YES] retain]; -(void) stopTimer{ [up invalidate]; //Do these same this line [up release]; //and this line in your dealloc up = nil; } - (void) doSomething{} @end
