1 找到某个图片的路径
首先跑程序出来，到达那个图片的位置，在控制台可以看到它的上一层的路径，在Finder点进去之后前往文件夹查看，核对的时候打开程序进行核对。
2 在平台加积分位置
// AppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
//加进去
[[CKCurrencyManager sharedInstance] addendCurrencyWithCount:1000];
3 View上加View
下载成功后的界面从cmplete按钮，变成一个View，这个View上有两个标签和一个image。
3.1 创建一个包含三个子控件view
首先第一步就是创建一个包含三个子控件view，不能创建成controller（不好往项目里加）。代码在CKDownloadFinishView.m中
3.1.1 属性声明
@property (nonatomic) UIImageView *imageView;
@property (nonatomic) UILabel *titleLabel;
@property (nonatomic) UILabel *subTitleLabel;
3.1.2 三个get方法
- (UIImageView *)imageView {
if (nil == _imageView) {
_imageView = [UIImageView new];
_imageView.image = [UIImage imageNamed:@"ic_Downloaded"];
}
return _imageView;
}
- (UILabel *)titleLabel {
if (nil == _titleLabel) {
_titleLabel = [UILabel new];
_titleLabel.text = NSLocalizedString(@"ck_button_downloaded", nil);
_titleLabel.font = [UIFont fontWithName:@"Helvetica-Bold" size:16.0f];
NSString *labelText = _titleLabel.text;
NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:labelText attributes:@{NSKernAttributeName:@(0.75)}];
NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
[attributedString addAttribute:NSParagraphStyleAttributeName value:paragraphStyle range:NSMakeRange(0, [labelText length])];
_titleLabel.attributedText = attributedString;
[_titleLabel sizeToFit];
}
return _titleLabel;
}
- (UILabel *)subTitleLabel {
if (nil == _subTitleLabel) {
_subTitleLabel = [UILabel new];
_subTitleLabel.text = NSLocalizedString(@"ck_download_finish_subTitle", nil);
_subTitleLabel.font = [UIFont fontWithName:@"Helvetica" size:12.0f];
NSString *labelText = _subTitleLabel.text;
NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:labelText attributes:@{NSKernAttributeName:@(0.56)}];
NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
[attributedString addAttribute:NSParagraphStyleAttributeName value:paragraphStyle range:NSMakeRange(0, [labelText length])];
_subTitleLabel.attributedText = attributedString;
[_subTitleLabel sizeToFit];
}
return _subTitleLabel;
}
3.1.3 初始化
- (instancetype)init {
if (self = [super init]) {
self.backgroundColor = [UIColor whiteColor];
[self addSubview:self.imageView];
[self addSubview:self.titleLabel];
[self addSubview:self.subTitleLabel];
}
return self;
}
3.1.4 更新约束
- (void)updateConstraints {
[super updateConstraints];
[self.imageView mas_remakeConstraints:^(MASConstraintMaker *make) {
make.left.equalTo(self.mas_left).offset(20.0f);
make.centerY.equalTo(self.mas_centerY);
}];
[self.titleLabel mas_remakeConstraints:^(MASConstraintMaker *make) {
make.top.equalTo(self.mas_top).offset(5.0f);
make.centerX.equalTo(self.mas_centerX);
}];
[self.subTitleLabel mas_remakeConstraints:^(MASConstraintMaker *make) {
make.top.equalTo(self.titleLabel.mas_bottom).offset(5.0f);;
make.bottom.equalTo(self.mas_bottom).offset(-5.0f);
make.centerX.equalTo(self.mas_centerX);
}];
}
3.2 到对应的Controller里面添加该View
这个是在CKCoolFontWindowController.m中出现的
3.2.1 声明属性
@property (nonatomic) CKDownloadFinishView *downloadFinishView;
3.2.2 写一个get方法
- (CKDownloadFinishView *)downloadFinishView {
if (nil == _downloadFinishView) {
_downloadFinishView = [CKDownloadFinishView new];
_downloadFinishView.hidden = YES;
}
return _downloadFinishView;
}
3.2.3 在loadView中加入自己写好的view
loadView方法是用来负责创建UIViewController的view。
这里要按照这个出现的先后顺序和覆盖去决定这个自己的view放在哪里，因为是在支付确认后弹出的，所以位置要放在它们两个后面。又因为这个view也在弹窗上面，所以需要把这个view添加到contentView上面。
[self.view addSubview:self.contentView];
······
[self.contentView addSubview:self.paymentButton];
[self.contentView addSubview:self.currencyButton];
[self.contentView addSubview:self.downloadFinishView];
3.2.4 相对布局
因为要覆盖掉之前的支付按钮，所以这个view的大小，至少要比按钮大。
而且位置也要放好，这个相对位置指的是和之前的某个标签的相对位置。
[self.paymentButton mas_makeConstraints:^(MASConstraintMaker *make) {
make.top.equalTo(self.uppercasesLabel.mas_bottom).offset(35.0f);
make.left.equalTo(self.contentView.mas_left).offset(14.0f);
make.right.equalTo(self.contentView.mas_right).offset(-14.0f);
make.height.mas_equalTo(46.0f);
}];
[self.currencyButton mas_makeConstraints:^(MASConstraintMaker *make) {
make.top.equalTo(self.paymentButton.mas_bottom).offset(16.0f);
make.left.equalTo(self.contentView.mas_left).offset(14.0f);
make.right.equalTo(self.contentView.mas_right).offset(-14.0f);
make.height.mas_equalTo(46.0f);
}];
[self.downloadFinishView mas_makeConstraints:^(MASConstraintMaker *make) {
make.top.equalTo(self.uppercasesLabel.mas_bottom).offset(35.0f);
make.left.equalTo(self.contentView.mas_left).offset(14.0f);
make.right.equalTo(self.contentView.mas_right).offset(-14.0f);
}];
3.2.5
在合适的地方让它出现就可以了
self.downloadFinishView.hidden = NO;
//必须加上执行代理方法回调
if ([self.delegate respondsToSelector:@selector(installDidcompleteForModel:)]) {
[self.delegate installDidcompleteForModel:self.model];
}
这里插一句在调试这个弹窗位置可以通过这个功能来确认自己的想法有没有出错。
4 修改版本号
./VersionChangeScript.sh -n
5 红点问题
1、声明一个未读的属性，这里面以Diy为例子
@property (nonatomic) UIView *unreadMessageDiyView;
2、给该属性一个get方法
这里可以直接输入属性名字就可以看到代码提示
如果这个view不存在的话，就初始化新建一个
设置好它的形状和背景并返回
- (UIView *)unreadMessageDiyView {
if (nil == _unreadMessageDiyView) {
_unreadMessageDiyView = [UIView new];
_unreadMessageDiyView.layer.cornerRadius = 2.5f;
_unreadMessageDiyView.backgroundColor = [UIColor redColor];
}
return _unreadMessageDiyView;
}
3、判断这个红点是否被点击，设置函数
三个形式
//CKTools.m
（1）是否超过12小时或者24小时，如果是的话就出现
+ (BOOL)unreadMessageForTimeDay {
NSDate *lastDate = [[NSUserDefaults standardUserDefaults] objectForKey:@"unreadMessageTime"];
if (nil == lastDate) return YES;
NSTimeInterval dayTime = [[NSDate date] timeIntervalSinceDate:lastDate];
if (dayTime > 12 * 60 * 60) {
return YES;
}
return NO;
}
（2）是否被点击过
+ (BOOL)unreadMessageForSticker{
return [[NSUserDefaults standardUserDefaults] boolForKey:@"unreadMessageForSticker"];
}
（3）需要判断某个值为真假才确定是否要添加红点
+ (BOOL)unreadMessageForAddAvator{
return [[[NSUserDefaults alloc] initWithSuiteName:AppGroupsNameString] boolForKey:@"changeUnreadMessageStatusForAvatarAddend"];
}
4、清除这个红点
（1）是否超过12小时或者24小时，如果是的话就取消红点
+ (void)unreadMessageClearDiy{
[[NSUserDefaults standardUserDefaults] setBool:YES forKey:@"unreadMessageForDiy"];
}
（2）是否被点击过，点击过的话就取消红点
+ (void)unreadMessageClearSticker{
[[NSUserDefaults standardUserDefaults] setBool:YES forKey:@"unreadMessageForSticker"];
}
5、在这个大的TopBar里面进行初始化
由于这个Diy菜单按钮是在menuContainerView里面，因此要是添加的话也应该是在这里。
//如果新添加过的avator，那么unreadMessageForAddAvator返回的值为true
if ([CKTools unreadMessageForAddAvator]) {
//[self.menuContainerView addSubview:self.unreadMessageThemeView];
//[self.menuContainerView addSubview:self.unreadMessageDiyView];
//如果未读，也就是unreadMessageForSticker == NO
if(NO == [CKTools unreadMessageForSticker]){
//将unreadMessageForSticker设置为YES，红点出现
[CKTools unreadMessageClearSticker];
[self.menuContainerView addSubview:self.unreadMessageStickerView];
}
}
if ([CKTools unreadMessageForTimeDay]) {
//unreadMessageForSticker为NO，代表sticker没有红点
if(NO == [CKTools unreadMessageForSticker]){
[self.menuContainerView addSubview:self.unreadMessageDiyView];
}
}
if(NO == [CKTools unreadMessageForAvator]) {
//[self.menuContainerView addSubview:self.unreadMessageAvatarsView];
}
6 心脏跳动问题
1、写出一个缩放效果的函数
-(CABasicAnimation *)scale:(NSNumber *)multiple withOrgin:(NSNumber *)orginMultiple durTimes:(float)time Rep:(float)repertTimes{
CABasicAnimation *animation = [CABasicAnimation animationWithKeyPath:@"transform.scale"];
animation.fromValue = multiple;
animation.toValue = orginMultiple;
animation.autoreverses = YES;
animation.repeatCount = repertTimes;
animation.duration = time;
animation.removedOnCompletion = NO;
animation.fillMode = kCAFillModeForwards;
return animation;
}
这里要注意，想要回到图片原始位置一定要
animation.removedOnCompletion = YES;
1、找到想要添加心脏跳动的按钮位置，在里面添加上这个特效
- (UIButton *)avatarsButton {
if (nil == _avatarsButton) {
_avatarsButton = [UIButton buttonWithType:UIButtonTypeCustom];
_avatarsButton.contentMode = UIViewContentModeScaleAspectFit;
[_avatarsButton addTarget:self action:@selector(actionForAvatarsButton:) forControlEvents:UIControlEventTouchDown];
[_avatarsButton.layer addAnimation:[self scale:[NSNumber numberWithFloat:1.2f] withOrgin:[NSNumber numberWithFloat:1.0f] durTimes:0.3f Rep:3] forKey:nil];
}
return _avatarsButton;
}
2、添加特效需要注意这几个参数
（1）缩放大小的倍数
numberWithFloat:9.0f
（2）缩放的速度
durTimes:0.3f
（3）节拍：
Rep:3
3、冬哥写的心脏跳动
CABasicAnimation *animation = [CABasicAnimation animationWithKeyPath:@"transform.scale"];
animation.fromValue = [NSNumber numberWithFloat:1.0f];
animation.toValue = [NSNumber numberWithFloat:1.4f];
//animation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseOut];
animation.duration = .3f;
animation.removedOnCompletion = NO;
animation.repeatCount = 4;
animation.autoreverses = YES;
animation.fillMode = kCAFillModeForwards;
[_stickerButton.layer addAnimation:animation forKey:nil];
