标签和Imageviews在iOS7中的自定义单元格中表现异常

Question

I have a custom cell that has labels and imageviews. The labels and imageviews are displayed based on the condition. My custom cell oddly behaves when uitableview is scrolled. There is an instance where when i scroll the one label and imageview the label and imageviews are displayed but when i scroll back to the imageviews and label one label and imageview will disappear, sometimes it overlaps another imageview and label. Here's what I tried so far:

static NSString *simpleTableIdentifier = @"JobDetailCell";
MTJobDetailCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier forIndexPath:indexPath];

if (cell == nil) {
    cell = [[MTJobDetailCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:simpleTableIdentifier];
}

I still get the same result. I read another solution and moved my calculations in my customcell.m file. This is in the layoutSubviews method.

NSInteger tempCount = [[NSUserDefaults standardUserDefaults] integerForKey:@"BenefitsCounter"];
NSDictionary *tempDictionary = [NSKeyedUnarchiver unarchiveObjectWithData:[[NSUserDefaults standardUserDefaults] objectForKey:@"IncentivesAndBenefits"]];
//TEST
NSLog(@"TEMP INT:%ld", (long)tempCount);
NSLog(@"TEMP ARRAY:%@", tempDictionary);

BOOL iFood = tempDictionary[@"food"][@"1"];
NSString* iFoodDescription = tempDictionary[@"food"][@"1"];
BOOL iCommission = tempDictionary[@"commission"][@"1"];
NSString* iCommissionDescription = tempDictionary[@"commission"][@"1"];
BOOL iUniform = tempDictionary[@"uniform"][@"1"];
NSString* iUniformDescription = tempDictionary[@"uniform"][@"1"];
BOOL iTransport = tempDictionary[@"transport"][@"1"];
NSString* iTransportDescription = tempDictionary[@"transport"][@"1"];
BOOL iExtras = tempDictionary[@"extras"][@"1"];
NSString* iExtrasDescription = tempDictionary[@"extras"][@"1"];

//MARK: POSITION labels and imageviews

My code works perfectly in iOS 8. Im really confused why it doesn't work in iOS 7. I have been struggling with this since last week. Can somebody please help me.

Answer 1

you may try below code -

Write Below code after

if (cell == nil) {
    cell = [[MTJobDetailCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:simpleTableIdentifier];
}

for(UIView *view in cell.contentView.subviews){  
        if ([view isKindOfClass:[UIView class]]) {  
            [view removeFromSuperview];   
        }
    }

AND

cell.clipsToBounds = YES;

Add all UIlabel and UIImage as below

[cell.contentView addSubview:myLabel] ;
