iOS开发惯用的第三方类库

2013-10-24 
iOS开发常用的第三方类库1 2 3 4 5 6 7 8 9 Reachability* reach [Reachability reachabilityWithHostna

iOS开发常用的第三方类库

  • 1 2 3 4 5 6 7 8 9 Reachability* reach = [Reachability reachabilityWithHostname:@"www.google.com"];reach.reachableBlock = ^(Reachability*reach) {    NSLog(@"网络可用!"); }; reach.unreachableBlock = ^(Reachability*reach) {    NSLog(@"网络不可用!"); }; // 开始监听 [reach startNotifier];

     

    ASIHTTPRequest 网络请求

    ASIHTTPRequest是对CFNetwork API的一个包装,它提供了一套更加简洁的API,使用起来也更加简单。

    官方网站:http://allseeing-i.com/ASIHTTPRequest/

    GitHub:https://github.com/pokeb/asi-http-request

    它不仅仅支持基本的HTTP请求,而且支持基于REST的服务(GET/POST/PUT/DELETE)。

    最让人喜欢的是,它支持block语法:

    1 2 3 4 5 6 7 8 9 10 11 12 13 NSURL *url = [NSURL URLWithString:@" http://allseeing-i.com "]; __block ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];[request setCompletionBlock:^{    // Use when fetching text data    NSString *responseString = [request responseString];     // Use when fetching binary data    NSData *responseData = [request responseData];}]; [request setFailedBlock:^{    NSError *error = [request error]; }]; [request startAsynchronous];

    它的ASIFormDataRequest子类可以横容易的提交表单数据和文件:

    1 2 3 4 5 6 7 8 ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];[request setPostValue:@"Ben" forKey:@"first_name"];[request setPostValue:@"Copsey" forKey:@"last_name"];// Upload a file on disk [request setFile:@"/Users/ben/Desktop/ben.jpg" withFileName:@"myphoto.jpg" andContentType:@"image/jpeg"forKey:@"photo"]; // Upload an NSData instance [request setData:imageData withFileName:@"myphoto.jpg" andContentType:@"image/jpeg" forKey:@"photo"];

    详细的使用方法请下载相应的源代码及例子,或者从官方的使用说明http://allseeing-i.com/ASIHTTPRequest/How-to-use开始。

     

    MBProgressHUD 提示效果

    支持各种状态加载的提示效果,以及带进度的提示效果。

    GitHub:https://github.com/matej/MBProgressHUD

    一般会在.m文件实现MBProgressHUDDelegate协议,并声明HUD变量:

    1 2 3 4 5 6 7 8 9 10 11 12 @interface SampleViewController ()<MBProgressHUDDelegate>{     MBProgressHUD *HUD; } #pragma mark - #pragma mark MBProgressHUDDelegate methods  - (void)hudWasHidden:(MBProgressHUD *)hud {  // Remove HUD from screen when the HUD was hidded  [HUD removeFromSuperview];   HUD = nil; }

    在执行某个异步请求时开始调用:

    1 2 3 4 5 HUD = [MBProgressHUD showHUDAddedTo:self.webView animated:YES];HUD.labelText = @"正在请求..."; // mode参数可以控制显示的模式 //HUD.mode = MBProgressHUDModeText; HUD.delegate = self;

    请求完成时隐藏提示效果:

    1 [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提示效果:

    1 [HUD showWhileExecuting:@selector(myTask) onTarget:self withObject:nil animated:YES];

     

    SVProgressHUD 提示效果

    GitHub:https://github.com/samvermette/SVProgressHUD

    SVProgressHUD和MBProgressHUD效果差不多,不过不需要使用协议,同时也不需要声明实例。

    直接通过类方法进行调用即可:

    1 [SVProgressHUD method]

    可以使用以下方法来显示状态:

    1 2 3 4 + (void)show; + (void)showWithMaskType:(SVProgressHUDMaskType)maskType;+ (void)showWithStatus:(NSString*)string;+ (void)showWithStatus:(NSString*)string maskType:(SVProgressHUDMaskType)maskType;

    如果需要明确的进度,则使用以下方法:

    1 2 3 + (void)showProgress:(CGFloat)progress; + (void)showProgress:(CGFloat)progress status:(NSString*)status;+ (void)showProgress:(CGFloat)progress status:(NSString*)status maskType:(SVProgressHUDMaskType)maskType;

    通过dismiss方法来隐藏提示:

    1 + (void)dismiss;

    另外提供了以下方法用于显示状态,并在1秒后自动隐藏提示(使用的图标来源于Glyphish:http://www.glyphish.com/):

    1 2 3 + (void)showSuccessWithStatus:(NSString*)string;+ (void)showErrorWithStatus:(NSString *)string;+ (void)showImage:(UIImage*)image status:(NSString*)string;// use 28x28 white pngs

     

    ZAActivityBar 提示效果

    GitHub:https://github.com/zacaltman/ZAActivityBar

    ZAActivityBar和SVProgressHUD非常相似,它提供了更加简洁的API来显示提示效果。

    ZAActivityBar使用的动画效果来源于ZKBounceAnimation(https://github.com/khanlou/SKBounceAnimation),成功、失败的状态图标来源于Pictos(http://pictos.cc/)。

    显示加载状态:

    1 [ZAActivityBar showWithStatus:@"加载中..."];

    显示成功、失败状态:

    1 2 [ZAActivityBar showSuccessWithStatus:@"成功!"];[ZAActivityBar showErrorWithStatus:@"失败!"];

    隐藏提示:

    1 [ZAActivityBar dismiss];

     

    SBJson JSON解析

    官方: http://sbjson.org/

    GitHub:https://github.com/stig/json-framework

    API使用起来稍显繁琐,特别是初始化的时候:

    1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 @interface TestViewController ()<SBJsonStreamParserAdapterDelegate> {    SBJsonStreamParser *parser;     SBJsonStreamParserAdapter *adapter; }   // 冗长的初始化方法足以吓到一大片人 - (void)initSBJSON {     // We don't want *all* the individual messages from the  // SBJsonStreamParser, just the top-level objects. The stream  // parser adapter exists for this purpose.  adapter = [[SBJsonStreamParserAdapter alloc] init];      // Set ourselves as the delegate, so we receive the messages  // from the adapter.   adapter.delegate = self;       // Create a new stream parser..   parser = [[SBJsonStreamParser alloc] init];      // .. and set our adapter as its delegate.  parser.delegate = adapter;       // Normally it's an error if JSON is followed by anything but  // whitespace. Setting this means that the parser will be  // expecting the stream to contain multiple whitespace-separated  // JSON documents.   parser.supportMultipleDocuments = YES;}   #pragma mark SBJsonStreamParserAdapterDelegate methods  - (void)parser:(SBJsonStreamParser *)parser foundArray:(NSArray *)array {    [NSExceptionraise:@"unexpected" format:@"Should not get here"];}   - (void)parser:(SBJsonStreamParser *)parser foundObject:(NSDictionary *)dict {    NSLog(@"SBJson parser foundObject");    // 处理返回的数据 }   // 使用ASIHTTPRequest请求测试 - (void) loadData {     __block ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];    [request setRequestMethod:@"POST"];     [request setCompletionBlock:^{         // Use when fetching text data         //NSString *responseString = [request responseString];        // Use when fetching binary data        NSData *responseData = [request responseData];        NSLog(@"Connection didReceiveData of length: %u", responseData.length);                  // Parse the new chunk of data. The parser will append it to        // its internal buffer, then parse from where it left off in        // the last chunk.         SBJsonStreamParserStatus status = [parser parse:responseData];                  if (status == SBJsonStreamParserError) {            NSLog(@"Parser error: %@", parser.error);        }else if (status == SBJsonStreamParserWaitingForData) {            NSLog(@"Parser waiting for more data");        }     }];     [request setFailedBlock:^{         NSError *error = [request error];        NSLog(@"failed - %@ %@", [error localizedDescription], error);    }];     [request startAsynchronous]; }

     

    JSONKit JSON解析

    GitHub:https://github.com/johnezang/JSONKit

    提供比SBJson更优异的性能以及更加简便的使用方法,但是中文最好使用utf-8格式(\uXXXX),否则容易造成乱码。

    API调用起来非常简单,省去了SBJson那么一大堆的方法:

    1 2 JSONDecoder* decoder = [[JSONDecoder alloc] initWithParseOptions:JKParseOptionNone];id result = [decoder objectWithData:jsonData];

    详细的使用方法请看它的GitHub主页。

     

    SDWebImage 图片异步加载及缓存

    SDWebImage用于异步下载网络上的图片,并支持对图片的缓存等。

    多数情况下是使用UIImageView+WebCache为UIImageView异步加载图片:

    1 2 3 4 #import <SDWebImage/UIImageView+WebCache.h>// ... [cell.imageView setImageWithURL:[NSURL URLWithString:@"http://www.domain.com/path/to/image.jpg"]                   placeholderImage:[UIImage imageNamed:@"placeholder.png"]];

    需要注意的是,pladeholderImage的大小一定要大于UIImageView的大小,否则可能不显示placeholderImage图片。

    它还支持block语法用于在加载完成时做一些操作:

    1 2 3 [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上,使用SDWebImageManager完成更多的操作:

    1 2 3 4 5 6 7 8 9 10 11 12 13 14 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:

    1 2 3 4 5 6 7 8 9 10 11 12 13 [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            }        }];

     

    UIActivityIndicator-for-SDWebImage 为SDWebImage显示加载效果

    GitHub:https://github.com/JJSaccolo/UIActivityIndicator-for-SDWebImage

    用于为SDWebImage在UIImageView加载图片时,显示加载效果(UIActivityIndicatorView实现),它提供以下方法:

    1 2 3 4 5 6 7 - (void)setImageWithURL:(NSURL *)url usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder options:(SDWebImageOptions)options usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;- (void)setImageWithURL:(NSURL *)url completed:(SDWebImageCompletedBlock)completedBlock usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder completed:(SDWebImageCompletedBlock)completedBlock usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder options:(SDWebImageOptions)options completed:(SDWebImageCompletedBlock)completedBlock usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder options:(SDWebImageOptions)options progress:(SDWebImageDownloaderProgressBlock)progressBlock completed:(SDWebImageCompletedBlock)completedBlock usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;

     

    UIImage+Resize 调整图片大小

    GitHub:https://github.com/coryalder/UIImage_Resize

    提供多种方法为图片设置透明度、圆角、裁剪、调整大小等:

    1 2 3 4 5 6 7 8 9 10 11 12 13 14 - (UIImage *)imageWithAlpha; - (UIImage *)transparentBorderImage:(NSUInteger)borderSize;- (UIImage *)roundedCornerImage:(NSInteger)cornerSize borderSize:(NSInteger)borderSize;- (UIImage *)croppedImage:(CGRect)bounds;- (UIImage *)thumbnailImage:(NSInteger)thumbnailSize          transparentBorder:(NSUInteger)borderSize               cornerRadius:(NSUInteger)cornerRadius       interpolationQuality:(CGInterpolationQuality)quality;- (UIImage *)resizedImage:(CGSize)newSize     interpolationQuality:(CGInterpolationQuality)quality;- (UIImage *)   resizedImageWithContentMode:(UIViewContentMode)contentMode                       bounds:(CGSize)bounds         interpolationQuality:(CGInterpolationQuality)quality;

    更详细使用见:http://vocaro.com/trevor/blog/2009/10/12/resize-a-uiimage-the-right-way/

     

    ImageCacheResize 异步加载图片、缓存及调整大小

    GitHub:https://github.com/toptierlabs/ImageCacheResize

    整合了SDWebImage和UIImage+Resize的功能,用于图片的异步加载、缓存、以及下载完成后调整大小并显示在UIImageView上。

    提供了以下API用于加载图片以及加载完成后调整图片大小:

    1 2 3 4 5 6 - (void)setImageWithURL:(NSURL *)url andCropToBounds:(CGRect)bounds;- (void)setImageWithURL:(NSURL *)url andResize:(CGSize)size withContentMode:(UIViewContentMode)mode;- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder andCropToBounds:(CGRect)bounds;- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder options:(SDWebImageOptions)options  andResize:(CGSize)size;- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder options:(SDWebImageOptions)options  andResize:(CGSize)size withContentMode:(UIViewContentMode)mode;- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder options:(SDWebImageOptions)options  andCropToBounds:(CGRect)bounds;

    使用方法和SDWebImage一样简单,如以下官方例子:

    1 2 [imageview setImageWithURL:[NSURL URLWithString:@"http://t0.gstatic.com/images?q=tbn:ANd9GcQfraHpiabjEY8iDdBe9OUQYHMtwfuAv9ZRR0RYKuoVF_EpE8Fp5A"] andResize:CGSizeMake(30, 30) withContentMode:UIViewContentModeScaleAspectFit]; // 按比例缩放[imageview setImageWithURL:[NSURL URLWithString:@"http://t0.gstatic.com/images?q=tbn:ANd9GcQfraHpiabjEY8iDdBe9OUQYHMtwfuAv9ZRR0RYKuoVF_EpE8Fp5A"] andCropToBounds:CGRectMake(0, 0, 100, 100)]; // 裁剪成100x100大小

     

    EGOTableViewPullRefresh  下拉刷新

    GitHub:https://github.com/enormego/EGOTableViewPullRefresh

    这是最早出现的为UITableView提供下拉刷新功能的类库,使用起来稍显麻烦,需要实现诸多协议(代码取自官方DEMO):
