// 下面这个方法一般用于普通控件,按钮btn比较特殊,需要指定状态
// [btn.imageView sd_setImageWithURL:[NSURL URLWithString:@"square.icon"] placeholderImage:[UIImage imageNamed:@"mine_icon_random"]];
// 可以通过[SDWebImageManager sharedManager]下载以后再进行赋值(这个可以拿到image存储url)

// 这个方法是btn特有的,这里直接使btn,而不是btn.image来设置图片,因为按钮在设置图片时才要指定状态
// 需#import "UIButton+WebCache.h"
[btn sd_setImageWithURL:[NSURL URLWithString:square.icon] forState:UIControlStateNormal];
// 5.监听按钮的点击
[btn addTarget:self action:@selector(squareBtnClick:) forControlEvents:UIControlEventTouchUpInside];

/**** 超过父控件部分,点击是无法响应的,要么改变父控件的大小,要么重写hitTest方法 ****/

}
@end
总结:
1.按钮设置图片和一般控件设置图片不同,需要指定状态才能设置成功
2.超过父控件部分,点击是无法响应的,要么改变父控件的大小,要么重写hitTest方法
3.2.AFNetWorking在发送https请求的时候会有点问题,但是设置为NO,则可以解决:
[AFHTTPSessionManager manager].securityPolicy.validatesDomainName = NO;
4.注意请求回来的对象的真实类型,id类型的对象在打方法的时候,显示出来的并不一定是正确的,可能在运行的时候就会崩溃,如:
- 下面方法会报错,因为NSDictionary没有该方法
[responseObject writeToFile:@"/Users/winson/Desktop/MyProject/5天/data.plist" options:0 error:nil];
- 正确写法如下:
[[AFHTTPSessionManager manager] GET:url parameters:paraDict progress:nil success:^(NSURLSessionDataTask * _Nonnull task, NSDictionary* responseObject) {
// 通过打印得知,该数据类型是字典,所以可以将id 改为 NSDictionary, 不然运行时调用方法时,会出错(拿来参考返回值的)
// [responseObject writeToFile:@"/Users/winson/Desktop/MyProject/5天/data.plist" atomically:YES];
// 字典转模型(此处是字典数组转模型数组),分类最好加前缀,例如这里的"mj_"
NSArray *squares = [ZGKMeSquareBtn mj_objectArrayWithKeyValuesArray:responseObject[@"square_list"]];
ZGKLog(@"字典转模型%@", squares);
[self creatSquaresBtn:squares];
// ZGKLog(@"请求数据成功 - %@ %@", [responseObject class], responseObject)
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
ZGKLog(@"请求数据失败 - %@", error)
}];
};
