一、YYModel
在iOS开发中总会用到各种JSON与模型相互转换的需求，之前的项目中一直使用MJExtension，但是最近发现一个轻量级的库YYModel，使用简单，性能也很不错，接下来就说说YYModel的一些简单的用法及注意事项。
1、JSON转换为模型，或者模型转换为JSON
JSON
{
accountId = "<null>";
avatarUrl = "http://thirdwx.qlogo.cn/mmopen/vi_32/sqicFCgiaheqCFbjrYgTmwXUQOB5l5Iyo47cVVp2cLlHARck6XgXscqicJ2ZVibicCbGH4iaVcQz8ptXqbV6n9ic5iaL9g/132";
unionId = o2t87wKAR1pNRZR0cnReBT608mok;
userid = 11703346;
wxNickName = "\U90a3\U5496";
}
Model
@property (nonatomic, strong) NSString *avatarUrl;
@property (nonatomic, strong) NSString *wxNickName;
@property (nonatomic, strong) NSString *accountId;
@property (nonatomic, strong) NSString *unionId;
@property (nonatomic, strong) NSString *userid;
JSON转换为模型
FansModel *fansModel = [FansModel yy_modelWithJSON:dic];
FansModel *fansModel = [FansModel yy_modelWithDictionary:dic];
模型转换为JSON
NSDictionary *json = [fansModel yy_modelToJSONObject];
2、手动创建的模型和服务端返回的模型属性名称不一致时
"userName" = "谢佳培";
"avatar" = "http://thirdwx.qlogo.cn/mmopen/vi_32/sqicFCgiaheqCFbjrYgTmwXUQOB5l5Iyo47cVVp2cLlHARck6XgXscqicJ2ZVibicCbGH4iaVcQz8ptXqbV6n9ic5iaL9g/132";
@property (nonatomic, strong) NSString *avatarUrl;
@property (nonatomic, strong) NSString *accountId;
+ (NSDictionary<NSString *, id> *)modelCustomPropertyMapper
{
return @{@"avatarUrl" : @"avatar",
@"wxNickName" : @"userName",
};
}
3、模型套模型
+ (NSDictionary *)modelContainerPropertyGenericClass
{
return @{@"areas" : [AreaModel class]};
}
ProvinceModel *provinceModel = [ProvinceModel yy_modelWithJSON:dict];
CityModel *cityModel = provinceModel.citys[0];
4、数组里面存放字典类型转换为模型
@implementation RabbitModel
@end
@implementation RabbitViewModel
// 转换为模型
- (void)manyRabbit
{
NSArray *array;
NSArray<RabbitModel *> *rabbitModelArray = [NSArray yy_modelArrayWithClass:[RabbitModel class] json:array];
}
@end
5、黑名单，即加入黑名单的字段会被忽略不会转换
将JSON转换为模型，转换出来的模型中的avatarUrl和accountId的值为nil。
@property (nonatomic, strong) NSString *avatarUrl;
@property (nonatomic, strong) NSString *accountId;
+ (NSArray *)modelPropertyBlacklist
{
return @[@"avatarUrl", @"accountId"];
}
6、白名单，即只处理加入白名单的字段，其余字段忽略掉
+ (NSArray *)modelPropertyWhitelist
{
return @[@"avatarUrl", @"accountId"];
}
二、UICountingLabel
UICountingLabel
1、做一个算数的
myLabel.method = UILabelCountingMethodLinear;// 线性变化
myLabel.format = @"%d";
[myLabel countFrom:1 to:10 withDuration:3.0];
2、使用ease-in-out（默认设置）将计数从5%增加到10%
countPercentageLabel.format = @"%.1f%%";
[countPercentageLabel countFrom:5 to:10];
3、使用使用数字格式化的字符串进行计数
NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];
formatter.numberStyle = kCFNumberFormatterDecimalStyle;
// 可以对显示的文本格式进行自定义
scoreLabel.formatBlock = ^NSString *(CGFloat value)
{
NSString *formatted = [formatter stringFromNumber:@((int)value)];
return [NSString stringWithFormat:@"Score: %@",formatted];
};
scoreLabel.method = UILabelCountingMethodEaseOut;// 开始速度很快，快结束时变得缓慢
[scoreLabel countFrom:0 to:10000 withDuration:2.5];// 可以指定动画的时长，默认时长是2.0秒
4、使用属性字符串计数
NSInteger toValue = 100;
// 用于设置属性字符串的格式，如果指定了formatBlock，则将会覆盖掉format属性，因为block的优先级更高
attributedLabel.attributedFormatBlock = ^NSAttributedString* (CGFloat value)
{
NSDictionary *normal = @{ NSFontAttributeName: [UIFont fontWithName: @"HelveticaNeue-UltraLight" size: 20] };
NSDictionary *highlight = @{ NSFontAttributeName: [UIFont fontWithName: @"HelveticaNeue" size: 20] };
NSString *prefix = [NSString stringWithFormat:@"%d", (int)value];
NSString *postfix = [NSString stringWithFormat:@"/%d", (int)toValue];
NSMutableAttributedString *prefixAttr = [[NSMutableAttributedString alloc] initWithString: prefix attributes: highlight];
NSAttributedString *postfixAttr = [[NSAttributedString alloc] initWithString: postfix attributes: normal];
[prefixAttr appendAttributedString: postfixAttr];
return prefixAttr;
};
[attributedLabel countFrom:0 to:toValue withDuration:2.5];
5、获得动画结束的事件
self.completionBlockLabel.method = UILabelCountingMethodEaseInOut;
self.completionBlockLabel.format = @"%d%%";
__weak UICountingLabelViewController *weakSelf = self;
self.completionBlockLabel.completionBlock = ^{
weakSelf.completionBlockLabel.textColor = [UIColor colorWithRed:0 green:0.5 blue:0 alpha:1];
};
[self.completionBlockLabel countFrom:0 to:100];
三、SDWebImage
多数情况下是使用UIImageView+WebCache为UIImageView异步加载图片：
#import <SDWebImage/UIImageView+WebCache.h>
[cell.imageView setImageWithURL:[NSURL URLWithString:@"http://www.domain.com/path/to/image.jpg"] placeholderImage:[UIImage imageNamed:@"placeholder.png"]];
它还支持block语法，用于在加载完成时做一些操作：
[cell.imageView setImageWithURL:[NSURL URLWithString:@"http://www.domain.com/path/to/image.jpg"] placeholderImage:[UIImage imageNamed:@"placeholder.png"] completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType) {
... completion code here ...
}];
SDWebImage并不局限于UIImageView，使用SDWebImageManager可完成更多的操作：
SDWebImageManager *manager = [SDWebImageManager sharedManager];
[manager downloadWithURL:imageURL options:0 progress:^(NSUInteger receivedSize, long long expectedSize) {
// 下载进度
} completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType) {
if (image)
{
// 下载完成
}
}];
或者使用Image Downloader也是一样的效果：
[SDWebImageDownloader.sharedDownloader downloadImageWithURL:imageURL options:0 progress:^(NSUInteger receivedSize, long long expectedSize) {
// 进度
} completed:^(UIImage *image, NSData *data, NSError *error, BOOL finished) {
if (image && finished)
{
// 下载完成
}
}];
四、SDCycleScrollView
SDCycleScrollView
1、带标题的网络图片
SDCycleScrollView *cycleScrollView = [SDCycleScrollView cycleScrollViewWithFrame:CGRectMake(0, 100, SCREEN_WIDTH, 200) delegate:self placeholderImage:[UIImage imageNamed:@"placeholder"]];
// page位置，默认居中
cycleScrollView.pageControlAliment = SDCycleScrollViewPageContolAlimentRight;
// 自定义分页控件小圆标颜色
cycleScrollView.currentPageDotColor = [UIColor whiteColor];
// 添加标题
cycleScrollView.titlesGroup = _titles;
[_ContainerView addSubview:cycleScrollView];
// 模拟加载延迟
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.3 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
cycleScrollView.imageURLStringsGroup = self->_imagesURLStrings;
});
// block监听点击方式
cycleScrollView.clickItemOperationBlock = ^(NSInteger currentIndex) {
NSLog(@"block监听点击方式，位置为：%ld", (long)currentIndex);
};
2、自定义分页控件
cycleScrollView.currentPageDotImage = [UIImage imageNamed:@"pageControlCurrentDot"];
cycleScrollView.pageDotImage = [UIImage imageNamed:@"pageControlDot"];
3、本地图片
SDCycleScrollView *cycleScrollView = [SDCycleScrollView cycleScrollViewWithFrame:CGRectMake(0, 650, SCREEN_WIDTH, 300) shouldInfiniteLoop:YES imageNamesGroup:_imageNames];
cycleScrollView.scrollDirection = UICollectionViewScrollDirectionVertical;
// 仅显示文字
NSMutableArray *titlesArray = [NSMutableArray new];
[titlesArray addObject:@"纯文字"];
[titlesArray addObjectsFromArray:_titles];
cycleScrollView.titlesGroup = [titlesArray copy];
[cycleScrollView disableScrollGesture];
[_ContainerView addSubview:cycleScrollView];
4、自定义cell的轮播图
a、如果要实现自定义cell的轮播图，必须先实现代理方法
_customCellScrollView = [SDCycleScrollView cycleScrollViewWithFrame:CGRectMake(0, 1000, SCREEN_WIDTH, 200) delegate:self placeholderImage:[UIImage imageNamed:@"placeholder"]];
_customCellScrollView.imageURLStringsGroup = _imagesURLStrings;
[_ContainerView addSubview:_customCellScrollView];
b、点击图片回调
- (void)cycleScrollView:(SDCycleScrollView *)cycleScrollView didSelectItemAtIndex:(NSInteger)index
{
NSLog(@"点击了第%ld张图片", (long)index);
[self.navigationController pushViewController:[NSClassFromString(@"DemoVC") new] animated:YES];
}
c、滚动到第几张图回调
- (void)cycleScrollView:(SDCycleScrollView *)cycleScrollView didScrollToIndex:(NSInteger)index
{
NSLog(@"滚动到第%ld张图", (long)index);
}
五、MBProgressHUD
MBProgress
实现MBProgressHUDDelegate协议，并声明HUD变量：
@interface ViewController () <MBProgressHUDDelegate>
{
MBProgressHUD *HUD;
}
#pragma mark - MBProgressHUDDelegate
- (void)hudWasHidden:(MBProgressHUD *)hud
{
[HUD removeFromSuperview];
HUD = nil;
}
在执行某个异步请求时开始调用：
HUD = [MBProgressHUD showHUDAddedTo:self.webView animated:YES];
HUD.labelText = @"正在请求...";
HUD.mode = MBProgressHUDModeText;// mode参数可以控制显示的模式
HUD.delegate = self;
请求完成时隐藏提示效果：
[HUD hide:YES];
对于同步方法一般都是用showWhileExecuting方法，方法执行完成之后会自动隐藏：
[HUD showWhileExecuting:@selector(myTask) onTarget:self withObject:nil animated:YES];
配置进度条的属性
// 只能设置菊花的颜色 全局设置
[UIActivityIndicatorView appearanceWhenContainedInInstancesOfClasses:@[[MBProgressHUD class]]].color = [UIColor redColor];
// 提示框格式 Determinate-圆形饼图 HorizontalBar- 水平进度条
// AnnularDeterminate-圆环 CustomView-自定义视图 Text-文本
self.progressHUD.mode = MBProgressHUDModeIndeterminate;
// 设置进度框中的提示文字
self.progressHUD.label.text = @"加载中...";
// 信息详情
_progressHUD.detailsLabel.text = @"人善如菊，夜凉如水...";
// 进度指示器 模式是0，取值从0.0————1.0
_progressHUD.progress = 0.5;
// 设置背景框的透明度，默认0.8
_progressHUD.bezelView.opaque = 1;
// 设置背景颜色之后opacity属性的设置将会失效
_progressHUD.bezelView.color = [[UIColor redColor] colorWithAlphaComponent:1];
// 背景框的圆角值，默认是10
_progressHUD.bezelView.layer.cornerRadius = 20;
// 置提示框的相对于父视图中心点位置，正值 向右下偏移，负值左上
[_progressHUD setOffset:CGPointMake(-80, -100)];
// 设置各个元素距离矩形边框的距离
[_progressHUD setMargin:5];
// 背景框的最小尺寸
_progressHUD.minSize = CGSizeMake(50, 50);
// 是否强制背景框宽高相等
_progressHUD.square = YES;
// ZoomOut:逐渐的后退消失 ZoomIn：前进淡化消失
// 默认类型的，渐变
_progressHUD.animationType = MBProgressHUDAnimationFade;
// 设置最短显示时间，为了避免显示后立刻被隐藏 默认是0
_progressHUD.minShowTime = 5;
// 被调用方法在宽限期内执行完，则HUD不会被显示
// 为了避免在执行很短的任务时，去显示一个HUD窗口
// _progressHUD.graceTime
// 设置隐藏的时候是否从父视图中移除，默认是NO
_progressHUD.removeFromSuperViewOnHide = NO;
// 显示进度框
[self.progressHUD showAnimated:YES];
// 两种隐藏的方法
// [_progressHUD hideAnimated:YES];
[_progressHUD hideAnimated:YES afterDelay:5];
// 隐藏时候的回调 隐藏动画结束之后
_progressHUD.completionBlock = ^{
NSLog(@"哈哈哈哈哈哈哈哈哈");
};
