巧妙的for循环

for (NSInteger i = 0; i < self.apearARR.count; i++) {

myflag = NO;

collect = [self.apearARR objectAtIndex:i];

if (loveButton.tag == collect.index) {

myflag = YES;

break;

}

}

if (myflag) {

[loveButton setImage:[UIImage imageNamed:@"tab2.png"] forState:UIControlStateNormal];

[sql deleteCollect:loveButton.tag];

}else{

[loveButton setImage:[UIImage imageNamed:@"tab2_checked.png"] forState:UIControlStateNormal];

CouponModel *model = self.firstArr[loveButton.tag - 20];

collect.couponName = [[model.couponUser objectForKey:@"coupon"] objectForKey:@"couponName"];

collect.descriPtion = [[model.couponUser objectForKey:@"coupon"] objectForKey:@"description"];

collect.couponUserId = [model.couponUser objectForKey:@"couponUserId"];

collect.logoUrl = [[[model.couponUser objectForKey:@"coupon"] objectForKey:@"mstStoresDetail"] objectForKey:@"logoUrl"];

collect.index = loveButton.tag;

collect.storeName = [self.OneArray objectAtIndex:0];

//            NSLog(@"tag = %ld", loveButton.tag);

[sql insertCollect:collect];

}

在for循环中做判断，如果符合条件，则中断for循环，break；跳出循环，可以直接以BOOL值来做后续的判断条件，以避免在for循环中判断方法走多次，而判断的混乱。
