此方法的GET和POST方法只能解析JSON数据
#import "AFNetworking.h"
{
NSString *api = @"http://api.class.room/?method=city&areacode=0101";
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
//只能解析JSON格式，若为html，则须设置一下
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];
[manager GET:api parameters:nil progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
NSLog(@"responseObject: %@", responseObject);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(@"error: %@", error);
}];
}
根据URL获取图片
#import "UIImageView+AFNetworking.h"
{
UIImageView *imageView = [UIImageView new];
imageView.frame = CGRectMake(0, 0, 200, 200);
imageView.center = self.view.center;
[self.view addSubview:imageView];
NSString *imageApi = @"http://atth.eduu.com/album/201203/12/1475134_1331559643qMzc.jpg";
[imageView setImageWithURL:[NSURL URLWithString:imageApi]];
button根据URL获取图片
#import "UIButton+AFNetworking.h"
{
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(0, 0, 100, 100);
button.center = self.view.center;
button.backgroundColor = [UIColor grayColor];
button.layer.cornerRadius = 50;
//裁剪掉多余的部分
button.clipsToBounds = YES;
[button addTarget:self action:@selector(didClick) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:button];
[button setImageForState:UIControlStateNormal withURL:[NSURL URLWithString:imageApi]];
}
- (void)didClick {
self.view.backgroundColor = [UIColor cyanColor];
}
