Install

Just add pod 'DQKFreezeWindowView', '~> 0.9.1' to your Podfile and pod install.

Use

Use DQKFreezeWindowView just like UITableView,it's similar but also powerful.

#import "DQKFreezeWindowView.h" anywhere you want to use.
Initialize the freezeWindowView:

DQKFreezeWindowView *freezeWindowView = [[DQKFreezeWindowView alloc] initWithFrame:frame];
    [self.view addSubview:freezeWindowView];
    freezeWindowView.dataSource = self;
    freezeWindowView.delegate = self;

Note:
sectionCell at the top, rowCell at the left.

Incomplete implementation (dataSource):

- (NSInteger)numberOfSectionsInFreezeWindowView:(DQKFreezeWindowView *)freezeWindowView {
    return 100;
}

- (NSInteger)numberOfRowsInFreezeWindowView:(DQKFreezeWindowView *)freezeWindowView {
    return 100;
}

- (DQKMainViewCell *)freezeWindowView:(DQKFreezeWindowView *)freezeWindowView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *mainCell = @"mainCell";
    DQKMainViewCell *mainCell = [freezeWindowView dequeueReusableMainCellWithIdentifier:mainCell forIndexPath:indexPath];
    if (mainCell == nil) {
        mainCell = [[DQKMainViewCell alloc] initWithStyle:DQKMainViewCellStyleDefault reuseIdentifier:calendarCell];
        mainCell.title = @"mainCell";
    }
    return mainCell;
}

- (DQKSectionViewCell *)freezeWindowView:(DQKFreezeWindowView *)freezeWindowView cellAtSection:(NSInteger)section {
    static NSString *sectionCell = @"sectionCell";
    DQKSectionViewCell *sectionCell = [freezeWindowView dequeueReusableSectionCellWithIdentifier:dayCell forSection:section];
    if (sectionCell == nil) {
        sectionCell = [[DQKSectionViewCell alloc] initWithStyle:DQKSectionViewCellStyleDefault reuseIdentifier:dayCell];
        sectionCell.title = @"sectionCell";
    }
    return sectionCell;
}

- (DQKRowViewCell *)freezeWindowView:(DQKFreezeWindowView *)freezeWindowView cellAtRow:(NSInteger)row {
    static NSString *rowCell = @"rowCell";
    DQKRowViewCell *rowCell = [freezeWindowView dequeueReusableRowCellWithIdentifier:timeCell forRow:row];
    if (rowCell == nil) {
        rowCell = [[DQKRowViewCell alloc] initWithStyle:DQKRowViewCellStyleDefault reuseIdentifier:timeCell];
        rowCell.title = @"rowCell";
    }
    return rowCell;
}

Incomplete implementation (delegate):

- (void)freezeWindowView:(DQKFreezeWindowView *)freezeWindowView didSelectIndexPath:(NSIndexPath *)indexPath {
    NSString *message = [NSString stringWithFormat:@"Click at section: %ld row: %ld",(long)indexPath.section,(long)indexPath.row];
    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"You did a click!" message:message delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
    [alertView show];
}

Note: For more information, you can see DQKFreezeWindowViewExample and DQKFreezeWindowViewDemo. I prefer to DQKFreezeWindowViewDemo, it's interesting.
