AFNetworking and MJExtension processing backend _ image framework SDWebImage (first draft ),

1. The AFNetworking Framework processes five types of requests, such as post get.

GET request:

AFHTTPRequestOperationManager *mgr=[AFHTTPRequestOperationManager manager];        NSMutableDictionary *params=[NSMutableDictionary dictionary];    [params setObject:account.access_token forKey:@"access_token"];        [mgr GET:@"https://api.weibo.com/2/statuses/friends_timeline.json" parameters:params success:^(AFHTTPRequestOperation *operation, NSDictionary *responseObject) {                NSArray *newStatus=[WBStatus objectArrayWithKeyValuesArray:responseObject[@"statuses"]];        NSIndexSet *set=[[NSIndexSet alloc] initWithIndexesInRange:NSMakeRange(0, newStatus.count)];        [self.statues insertObjects:newStatus atIndexes:set];        [self.tableView reloadData];            } failure:^(AFHTTPRequestOperation *operation, NSError *error) {        NSLog(@"%@",[error localizedDescription]);    }];

POST request:

AFHTTPRequestOperationManager *mgr=[AFHTTPRequestOperationManager manager];        NSMutableDictionary *param=[NSMutableDictionary dictionary];    [param setObject:@"43435345453 forKey:@"client_id"];    [param setObject:@"354083454f535fv53c53d97" forKey:@"client_secret"];    [param setObject:@"authorization_code" forKey:@"grant_type"];    [param setObject:@"http://www.baidu.com" forKey:@"redirect_uri"];    [param setObject:code forKey:@"code"];        [mgr POST:@"https://api.weibo.com/oauth2/access_token" parameters:param success:^(AFHTTPRequestOperation *operation, NSDictionary *responseObject) {            } failure:^(AFHTTPRequestOperation *operation, NSError *error) {            }];

2. The MJExtension user directly processes the conversion between the Dictionary and Bean.

#import <Foundation/Foundation.h>#import "WBUser.h"@interface WBStatus : NSObject@property (nonatomic,copy) NSString *text;@property (nonatomic,copy) NSString *idStr;@property (nonatomic,strong) WBUser *user;@end

Corresponding json:

"Statuses": [{"id": 11488058246, "text": "follow. ",... "User": {"id": 1404376560, "name": "zaku", "description": "If you have lived for fifty years, it's like a dream, what do you regret. "," Url ":" http://blog.sina.com.cn/zaku "," profile_image_url ":" http://tp1.sinaimg.cn/1404376560/50/0/1 ",...},...]

The following example converts json into data:

#import "MJExtension.h"NSArray *newStatus=[WBStatus objectArrayWithKeyValuesArray:jsonStr];

3. Image Display framework SDWebImage

#import "UIImageView+WebCache.h"NSURL *url=[NSURL URLWithString:urlStr];UIImage *placehoder = [UIImage imageNamed:@"default_image"];[imageView sd_setImageWithURL:url placeholderImage:placehoder];

Disable download and clear memory when the application has no memory

-(void)applicationDidReceiveMemoryWarning:(UIApplication *)application{    SDWebImageManager *mgr=[SDWebImageManager sharedManager];        [mgr cancelAll];        [mgr.imageCache clearMemory];    }
