常用三方
Reachability 检 测网络连接
用来检查网络连接是否可用:包括WIFI和 WWAN(3G/EDGE/CDMA等)两种工作模式。
可以从Apple网站下载到: http://developer.apple.com/library/ios/#samplecode/Reachab ility/History/History.html#//apple_ref/doc/uid/DTS40007324-R evisionHistory-DontLinkElementID_1。
现在有更好的替代品: https://github.com/tonymillion/Reachability,比Apple??供的兼 容性更好,而且更加好用,更具体的使用方法请看它??供的例 子。
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];
ASIHTTPReque st 网络请求
ASIHTTPRequest是对CFNetwork API的一个包装,它??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:
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??交表单数据和
文件:
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。
MBProgressHU
D ??示效果
支持各种状态加载的??示效果,以及带进度的??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:
@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:
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??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??示效果:
[HUD showWhileExecuting:@selector(myTask) onTarget:self withObject:nil animated:YES];
SVProgressHU D ??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:
[SVProgressHUD method]
可以使用以下方法来显示状态:
+ (void)show;+ (void)showWithMaskType:(SVProgressHUDMaskTyp e)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:
+ (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??示: + (void)dismiss;
另外??供了以下方法用于显示状态,并在1秒后自动隐藏??示 (使用的图标来源于Glyphish:http://www.glyphish.com/):
+ (void)showSuccessWithStatus:(NSString*)strin g;+ (void)showErrorWithStatus:(NSString *)string;+ (void)showImage:(UIImage*)image status:(NSString*)string; // use 28x28 white pngs
ZAActivityBar
??示效果
GitHub:https://github.com/zacaltman/ZAActivityBar ZAActivityBar和SVProgressHUD非常相似,它??供了更加简
洁的API来显示??示效果。
ZAActivityBar使用的动画效果来源于 ZKBounceAnimation(https://github.com/khanlou/SKBounceA nimation),成功、失败的状态图标来源于 Pictos(http://pictos.cc/)。
显示加载状态:
[ZAActivityBar showWithStatus:@"加载中..."];
显示成功、失败状态:
[ZAActivityBar showSuccessWithStatus:@"成
功!"];[ZAActivityBar showErrorWithStatus:@"失
败!"];
隐藏??示:
[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:
@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
{ [NSException raise:@"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
??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:
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:
#import
<SDWebImage/UIImageView+WebCache.h>// ...[ce
ll.imageView setImageWithURL:[NSURL
URLWithString:@"http://www.domain.com/path/t
o/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:
[cell.imageView setImageWithURL:[NSURL
URLWithString:@"http://www.domain.com/path/t
o/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:
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 } }];

UIImage+Resize
调整图片大小
GitHub:https://github.com/coryalder/UIImage_Resize
??供多种方法为图片设置透明度、圆角、裁剪、调整大小等:
- (UIImage *)imageWithAlpha;- (UIImage
*)transparentBorderImage:(NSUInteger)borderS
ize;- (UIImage

e-right-way/
ImageCacheRe
size 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。
??供了以下API用于加载图片以及加载完成后调整图片大小:
- (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:
[imageview setImageWithURL:[NSURL
URLWithString:@"http://t0.gstatic.com/images
?q=tbn:ANd9GcQfraHpiabjEY8iDdBe9OUQYHMtwfuAv
9ZRR0RYKuoVF_EpE8Fp5A"]
andResize:CGSizeMake(30, 30)
withContentMode:UIViewContentModeScaleAspect
Fit]; // 按比例缩放[imageview
setImageWithURL:[NSURL
URLWithString:@"http://t0.gstatic.com/images
?q=tbn:ANd9GcQfraHpiabjEY8iDdBe9OUQYHMtwfuAv
9ZRR0RYKuoVF_EpE8Fp5A"]
andCropToBounds:CGRectMake(0, 0, 100, 100)]; //
裁剪成100x100大小
EGOTableView
