iOS 定时器封装

支持启动多个定时器，关闭的时候要记住回调出来的TimeModle的名字

#import <Foundation/Foundation.h>

#import "BLAppDelegate.h"

typedef
void(^TimeManagerCallback)(BOOL success,
id result);

@interface TimeManager :
NSObject

/*

name 唯一标示

num 超时时间

*/
+ (void)initTime:(int)num callback:(TimeManagerCallback)callback;
+ (void)closeTime:(NSString *)name;
+ (void)closeTime;

/*

例子

- (void)close:(UIButton *)button{

[TimeManager closeTime:@"BLLogin"];

}

- (void)login:(UIButton *)button

{

[TimeManager initTime:@"BLLogin" timeout:30 callback:^(BOOL success, id result){

if (success) {

NSLog(@"success");

}

}];

}
