A multi-choice control with animation in IOS (2)

Then let's write: TypeSelectView

This is relatively simple. We only need to position each TypeView and use it as our subview.

@interface TypeSelectView : UIView@property(nonatomic) BOOL bShown;@property(nonatomic, strong) TypeView* curSelectedView;-(id)initWithFrame:(CGRect)frame searchType:(int)type;@end

-(id)initWithFrame:(CGRect)frame searchType:(int)type{    self = [super initWithFrame:frame];    if (self) {        _bShown = NO;        self.backgroundColor = [UIColor clearColor];        CGRect rcBg = frame;        rcBg.origin.y = 0.0f;        rcBg.origin.x = 0.0f;        UIImageView *bgImageView = [[UIImageView alloc] initWithFrame:rcBg];        bgImageView.image = [UIImage imageNamed:@"change_icon_bg.png"];        [self addSubview:bgImageView];                CGRect typeRc =CGRectMake(4.0f, 0.0f, TypeView_Width, TypeView_Height);        for (int i = 0; i < 4; i++) {            TypeView *curTypeView = [[TypeView alloc] initWithFrame:typeRc];            curTypeView.typesView = self;            curTypeView.typeId = i;            if (i == type) {                curTypeView.bSelected = YES;                self.curSelectedView = curTypeView;            }            [self addSubview:curTypeView];                        if (i == 3) {                typeRc.origin.x = 4.0f;                typeRc.origin.y = 78.0f;            }else {                typeRc.origin.x += 314.0f/4;            }        }    }        return self;}    

Then we write TopBarView

@interface TopBarView : UIView-(void)layoutViews;@property(nonatomic,strong)TopBarControllerViewController* myViewController;@property(nonatomic)UIButton* button;@property(nonatomic)UITextField* textField;@property (nonatomic, strong) TypeSelectView *topTypesView;-(void)onclick;@end

The code for adding TypeSelectView is:

-(Void) layoutViews {self. clipsToBounds = YES; _ topTypesView. bShown = NO; TypeSelectView * tmpType = [[TypeSelectView alloc] initWithFrame: [[HomePageUIManager sharedInstance] searchTypesOriginFrame] searchType: 0]; _ topTypesView. autoresizingMask = bytes | UIViewAutoresizingFlexibleWidth | bytes; _ topTypesView = tmpType; // write _ topTypesView after these views [[MyViewController sharedInstance]. view insertSubview: _ topTypesView belowSubview: self];

Add _ topTypesView to the end of [MyViewController sharedInstance]. view so that the initial position can be covered by TopBarView. the initial position of _ topTypeView is:

- (CGRect)searchTypesOriginFrame{return CGRectMake(0.0f, 44.0f- 80.0f, 320.0f, 80.0f);}

The position shown in the show is:

- (CGRect)searchTypesShowFrame{return CGRectMake(0.0f, 44.0f, 320.0f, 80.0f);}

The Code of show TypeSelectedView is to change the frame of _ topTypesView. hide is to reverse the frame.

- (void)toShowTypesView {    _topTypesView.frame = [[HomePageUIManager sharedInstance] searchTypesOriginFrame];[UIView beginAnimations:@"ShowTypes" context:NULL];[UIView setAnimationDuration:0.4f];[UIView setAnimationDelegate:self];[UIView setAnimationDidStopSelector:@selector(animationDidStop:finished:context:)];[UIView setAnimationBeginsFromCurrentState:YES];[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];    _topTypesView.bShown = YES;_topTypesView.frame = [[HomePageUIManager sharedInstance] searchTypesShowFrame];        [UIView commitAnimations];}

MyViewController initialization:

-(Id) initWithNibName :( NSString *) nibNameOrNil bundle :( NSBundle *) handle {self = [super initWithNibName: nibNameOrNil bundle: callback]; if (self) {// Custom initialization// Self. view. backgroundColor = [MyViewController RGBColorFromHexString: @ "# eeeeee" alpha: 1.0f]; // do not add this sentence. If it is added, MyViewController will execute viewdidload, causing program crash.} Return self;} // statement + (MyViewController *) sharedInstance {static MyViewController * _ sharedInstance = nil; if (_ sharedInstance = nil) _ sharedInstance = [[MyViewController alloc] initWithNibName: nil bundle: nil]; return _ sharedInstance;}-(void) viewDidLoad {[super viewDidLoad]; // Do any additional setup after loading the view. CGRect rcSearchBar = [[HomePageUIManager sharedInstance] searchBarViewFrame]; TopBarView * tmpView = [[TopBarView alloc] initWithFrame: rcSearchBar]; [tmpView layoutViews]; [self. view addSubview: tmpView]; UIView * view = [[UIView alloc] initWithFrame: CGRectMake (0, 44,320, 2)]; view. backgroundColor = [UIColor grayColor]; [self. view addSubview: view];}
