主要重点
1.整体架构
利用UITabBarController和UINavigationController配合实现.其中要注意定义基类,方便整体上的管理,例如对UINavigationController头部的颜色,字体和渲染颜色等设置.以及对UITabBarController的底部的渲染等.
[self.navigationBarsetBackgroundImage:[UIImageimageNamed:@"Dimensional-_Code_Bg"]forBarMetrics:UIBarMetricsDefault];[self.navigationBarsetTitleTextAttributes:@{ NSForegroundColorAttributeName:[UIColor whiteColor]}]; [self.navigationBarsetTintColor:[UIColor whiteColor]];2.发现界面和我的界面
- (instancetype)initWithDict:(NSDictionary *)dict{ if (self = [super init]) {[selfsetValuesForKeysWithDictionary:dict];}return self;} + (instancetype)pictureWithDict:(NSDictionary *)dict{ return [[self alloc]initWithDict:dict];}3.朋友圈功能的实现
- (void)scrollViewWillBeginDragging:(UIScrollView *)scrollView{ self.dragging = YES;}- (void)scrollViewDidScroll:(UIScrollView *)scrollView{ if (self.num == 0) {self.num ++;return;} CGFloat offsetY = scrollView.contentOffset.y; CGFloat angle = -offsetY* M_PI / 30; if (self.dragging == YES) { if (offsetY <= 110) {self.containerView.y = 10 + offsetY; } }else { if (self.currentY < 120) {self.containerView.y = 10 + offsetY;} }self.activityView.transform = CGAffineTransformMakeRotation(angle); }- (void)scrollViewDidEndDragging:(UIScrollView *)scrollViewwillDecelerate:(BOOL)decelerate{ self.dragging = NO; CGFloat currentY = self.containerView.y;self.currentY = currentY; } - (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView{ [UIViewanimateWithDuration:0.25animations:^{ self.containerView.frame = CGRectMake(15, 120, 30, 30);self.activityView.transform = CGAffineTransformMakeRotation(2 * M_PI);}]; }其中照片的展示是采用UICollectionViewController来实现的.没有直接调用系统的相册,因此加大了难度.自定义了cell,并采用了代理方式来实现类与类之间的通信.
@protocol YYPictureCellDelegate @optional- (void)pictureCell:(YYPictureCell *)cellwithDidClickBtn:(UIButton *)btn; @end - (IBAction)clickSureBtn:(UIButton *)sender { if ([self.delegaterespondsToSelector:@selector(pictureCell:withDidClickBtn:)]) { [self.delegatepictureCell:selfwithDidClickBtn:sender];}} - (void)pictureCell:(YYPictureCell *)cellwithDidClickBtn:(UIButton *)btn{ if ((self.selectedBtn.count == 9) && (!btn.isSelected)) { UIAlertView *alert = [[UIAlertView alloc]initWithTitle:nilmessage:@"最多选取9张照片哦,亲!"delegate:nilcancelButtonTitle:@"确定"otherButtonTitles: nil];[alertshow]; return;} btn.selected = !btn.isSelected; NSIndexPath *indexPath = [self.collectionViewindexPathForCell:cell]; YYPictureModel *model = self.dataArray[indexPath.row]; if (btn.isSelected) { model.clickedBtn = YES; [self.selectedBtnaddObject:btn];[self.selImageArrayaddObject:model]; } else{ model.clickedBtn = NO;[self.selectedBtnremoveObject:btn];[self.selImageArrayremoveObject:model];} if (self.selectedBtn.count > 0) { self.doneBtn.enabled = YES;self.doneBtn.selected = YES;self.previewBtn.enabled = YES;self.previewBtn.selected = YES;}else { self.doneBtn.enabled = NO;self.doneBtn.selected = NO;self.previewBtn.enabled = NO;self.previewBtn.selected = NO;} }4.摇一摇功能的实现
//实现摇一摇功能- (void)motionBegan:(UIEventSubtype)motionwithEvent:(UIEvent *)event{ self.upLine.hidden = NO;self.downLine.hidden = NO;[UIViewanimateWithDuration:0.6animations:^{ self.upImageView.y -= 60;self.upLine.y -= 60; self.downImageView.y += 60;self.downLine.y += 60; }completion:^(BOOL finished) { [UIViewanimateWithDuration:0.6animations:^{ self.upImageView.y += 60;self.upLine.y += 60; self.downImageView.y -= 60;self.downLine.y -= 60; }completion:^(BOOL finished) { self.upLine.hidden = YES;self.downLine.hidden = YES; //弹出搜索框[self showSearchView];[self.searchViewperformSelector:@selector(removeFromSuperview)withObject:nilafterDelay:2.4];}]; }];}//摇一摇结束后- (void)motionEnded:(UIEventSubtype)motionwithEvent:(UIEvent *)event{ }以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持脚本之家。
