1、网络请求封装(NSURLSESSION / AFNetwork)
GET 用法
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
[manager GET:URL parameters:nil progress:^(NSProgress * _Nonnull downloadProgress) {
}
success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
NSLog(@"这里打印请求成功要做的事");
}
failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(@"%@",error); //这里打印错误信息
}];
POST 用法
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
NSMutableDictionary *parameters = @{@"":@"",@"":@""};
[manager POST:URL parameters:parameters progress:^(NSProgress * _Nonnull uploadProgress) {
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
}];
文件上传
/**
* AFN 3.0 上传
* 有两种方式
* upLoad1 和 upLoad2
*/
//第一种方法是通过工程中的文件进行上传
- (void)upLoad1{
//1。创建管理者对象
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
//2.上传文件
NSDictionary *dict = @{@"username":@"1234"};
NSString *urlString = @"22222";
[manager POST:urlString parameters:dict constructingBodyWithBlock:^(id<AFMultipartFormData> _Nonnull formData) {
//上传文件参数
UIImage *iamge = [UIImage imageNamed:@"123.png"];
NSData *data = UIImagePNGRepresentation(iamge);
//这个就是参数
[formData appendPartWithFileData:data name:@"file" fileName:@"123.png" mimeType:@"image/png"];
} progress:^(NSProgress * _Nonnull uploadProgress) {
//打印下上传进度
WKNSLog(@"%lf",1.0 *uploadProgress.completedUnitCount / uploadProgress.totalUnitCount);
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
//请求成功
WKNSLog(@"请求成功:%@",responseObject);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
//请求失败
WKNSLog(@"请求失败:%@",error);
}];
}
//第二种是通过URL来获取路径,进入沙盒或者系统相册等等
- (void)upLoda2{
//1.创建管理者对象
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
//2.上传文件
NSDictionary *dict = @{@"username":@"1234"};
NSString *urlString = @"22222";
[manager POST:urlString parameters:dict constructingBodyWithBlock:^(id<AFMultipartFormData> _Nonnull formData) {
[formData appendPartWithFileURL:[NSURL fileURLWithPath:@"文件地址"] name:@"file" fileName:@"1234.png" mimeType:@"application/octet-stream" error:nil];
} progress:^(NSProgress * _Nonnull uploadProgress) {
//打印下上传进度
WKNSLog(@"%lf",1.0 *uploadProgress.completedUnitCount / uploadProgress.totalUnitCount);
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
//请求成功
WKNSLog(@"请求成功:%@",responseObject);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
//请求失败
WKNSLog(@"请求失败:%@",error);
}];
}
文件下载
/**
* AFN3.0 下载
*/
- (void)downLoad{
//1.创建管理者对象
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
//2.确定请求的URL地址
NSURL *url = [NSURL URLWithString:@""];
//3.创建请求对象
NSURLRequest *request = [NSURLRequest requestWithURL:url];
//下载任务
NSURLSessionDownloadTask *task = [manager downloadTaskWithRequest:request progress:^(NSProgress * _Nonnull downloadProgress) {
//打印下下载进度
WKNSLog(@"%lf",1.0 * downloadProgress.completedUnitCount / downloadProgress.totalUnitCount);
} destination:^NSURL * _Nonnull(NSURL * _Nonnull targetPath, NSURLResponse * _Nonnull response) {
//下载地址
WKNSLog(@"默认下载地址:%@",targetPath);
//设置下载路径,通过沙盒获取缓存地址,最后返回NSURL对象
NSString *filePath = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES)lastObject];
return [NSURL fileURLWithPath:filePath];
} completionHandler:^(NSURLResponse * _Nonnull response, NSURL * _Nullable filePath, NSError * _Nullable error) {
//下载完成调用的方法
WKNSLog(@"下载完成:");
WKNSLog(@"%@--%@",response,filePath);
}];
//开始启动任务
[task resume];
}
2、JSON 格式化
3、线程管理
-
NSThread
-
GCD
-
NSOperation
4、图片的下载与存储
-
SDWebImage 开源框架
5、文件管理
-
NSFileManager
-
NSFileHandle
-
序列化数据
6、布局
-
Frame
-
AutoLayout
-
开源布局框架
7、适配
8、启动屏/跳转
- 启动屏
两种方案:1、系统级别的View,配置LaunchScreen ;2、业务级别的 View,自定义一个View,添加到 window 上,在适当的时机移除 -
跳转
1、URLSchema
有风险
2、Universal Link
