VTMagic is available through CocoaPods. To install it, simply add the following line to your Podfile, and then import <VTMagic/VTMagic.h>:
pod "VTMagic"- Download the project and drop
VTMagicfolder into your project. - Import file
VTMagic.h.
#import "VTMagic.h"This library requires iOS 6.0+ and Xcode 7.0+.
To run the example project, clone the repo, and run pod install from the project directory first.
- (void)viewDidLoad {
[super viewDidLoad];
[self addChildViewController:self.magicController];
[self.view addSubview:_magicController.view];
[_magicController.magicView reloadData];
}
- (VTMagicController *)magicController {
if (!_magicController) {
_magicController = [[VTMagicController alloc] init];
_magicController.magicView.navigationColor = [UIColor whiteColor];
_magicController.magicView.sliderColor = [UIColor redColor];
_magicController.magicView.layoutStyle = VTLayoutStyleDivide;
_magicController.magicView.switchStyle = VTSwitchStyleDefault;
_magicController.magicView.navigationHeight = 40.f;
_magicController.magicView.dataSource = self;
_magicController.magicView.delegate = self;
}
return _magicController;
}or like this
#import "VTMagicController.h"
@interface ViewController : VTMagicController
@end@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
self.magicView.navigationColor = [UIColor whiteColor];
self.magicView.sliderColor = [UIColor redColor];
self.magicView.layoutStyle = VTLayoutStyleDefault;
self.magicView.switchStyle = VTSwitchStyleDefault;
self.magicView.navigationHeight = 40.f;
self.magicView.dataSource = self;
self.magicView.delegate = self;
[self.magicView reloadData];
}You must conform to <VTMagicViewDataSource>. <VTMagicViewDelegate> and <VTMagicReuseProtocol> are optional.
- (NSArray<NSString *> *)menuTitlesForMagicView:(VTMagicView *)magicView {
return _menuList;
}
- (UIButton *)magicView:(VTMagicView *)magicView menuItemAtIndex:(NSUInteger)itemIndex {
static NSString *itemIdentifier = @"itemIdentifier";
UIButton *menuItem = [magicView dequeueReusableItemWithIdentifier:itemIdentifier];
if (!menuItem) {

[menuItem setTitleColor:RGBCOLOR(50, 50, 50) forState:UIControlStateNormal];

menuItem.titleLabel.font = [UIFont fontWithName:@"Helvetica" size:16.f];
}
return menuItem;
}
- (UIViewController *)magicView:(VTMagicView *)magicView viewControllerAtPage:(NSUInteger)pageIndex {
if (0 == pageIndex) {
static NSString *recomId = @"recom.identifier";
VTRecomViewController *recomViewController = [magicView dequeueReusablePageWithIdentifier:recomId];
if (!recomViewController) {
recomViewController = [[VTRecomViewController alloc] init];
}
return recomViewController;
}
static NSString *gridId = @"grid.identifier";
VTGridViewController *gridViewController = [magicView dequeueReusablePageWithIdentifier:gridId];
if (!gridViewController) {
gridViewController = [[VTGridViewController alloc] init];
}
return gridViewController;
}- (void)magicView:(VTMagicView *)magicView viewDidAppear:(UIViewController *)viewController atPage:(NSUInteger)pageIndex {
NSLog(@"pageIndex:%ld viewDidAppear:%@", (long)pageIndex, viewController.view);
}
- (void)magicView:(VTMagicView *)magicView viewDidDisappear:(UIViewController *)viewController atPage:(NSUInteger)pageIndex {
NSLog(@"pageIndex:%ld viewDidDisappear:%@", (long)pageIndex, viewController.view);
}
- (void)magicView:(VTMagicView *)magicView didSelectItemAtIndex:(NSUInteger)itemIndex {
NSLog(@"didSelectItemAtIndex:%ld", (long)itemIndex);
}This method will be called when page is reused, you should clear old data or reset content offset in here.
- (void)vtm_prepareForReuse {
NSLog(@"clear old data if needed:%@", self);
}VTMagic will automatically calls the appearance callbacks when user switches the page, maybe you should do something in here, e.g. refresh page info.
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
// do something...
}
- (void)viewWillDisappear:(BOOL)animated {
[super viewWillDisappear:animated];
// do something...
}
You can get the nearest magicController in any child view controller which is conforms to <VTMagicProtocol>, after you import file VTMagic.h.
NSInteger currentPage = self.magicController.currentPage;
UIViewController *viewController = self.magicController.currentViewController;You can switch to some specified page.
[self.magicView switchToPage:3 animated:YES];
[self.magicController switchToPage:3 animated:YES];You can get any page controller by page index, it will return nil if the page is not on the screen.
UIViewController *viewController = [self.magicView viewControllerAtPage:3];
UIViewController *viewController = [self.magicController viewControllerAtPage:3];VictorTian email: tianzhuo112@163.com
