p.p1 { margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px "PingFang SC"; color: #000000 }
span.s1 { }
span.s2 { font: 18.0px Menlo }
p.p1 { margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px "PingFang SC"; color: #1e9421 }
p.p2 { margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; color: #1e9421 }

span.s3 { color: #000000 }
span.s4 { font: 18.0px "PingFang SC" }
//静态库一般做一下几种事情
//1 工具类 算法逻辑
新建工具类LHQTools
定义类方法
p.p1 { margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; color: #000000 }
span.s1 { }
span.s2 { color: #703daa }
+ (NSInteger)sumWithNum1: (NSInteger)num1 andNum2:(NSInteger)num2;
类方法的实现
p.p1 { margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; color: #000000 }
p.p2 { margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; color: #000000; min-height: 21.0px }
span.s1 { }
span.s2 { color: #703daa }
span.s3 { color: #c42275 }
+(NSInteger)sumWithNum1:(NSInteger)num1 andNum2:(NSInteger)num2{
return num1 + num2;
}
使用
在主控制器计算值
p.p1 { margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; color: #294c50 }
span.s1 { color: #000000 }
span.s2 { color: #3e1e81 }
span.s3 { color: #c81b13 }
span.s4 { color: #c42275 }
span.s5 { color: #3c828b }
span.s6 { }
span.s7 { color: #0435ff }
NSLog(@"%ld",(long)[LHQTools sumWithNum1:10 andNum2:10]);
p.p1 { margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px "PingFang SC"; color: #1e9421 }
span.s1 { font: 18.0px Menlo }
span.s2 { }
//2 实现加载一定的资源,放在bundle中避免资源重名
将存放图片的bundle拖入文件夹
定义类方法
p.p1 { margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; color: #000000 }
span.s1 { }
span.s2 { color: #6122ae }
+ (UIImage *)loadLogo;
实现类方法
p.p1 { margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; color: #000000 }
p.p2 { margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; color: #1e9421 }
p.p3 { margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; color: #c81b13 }
span.s1 { }
span.s2 { color: #6122ae }
span.s3 { color: #000000 }
span.s4 { font: 18.0px "PingFang SC" }
span.s5 { color: #c42275 }
span.s6 { color: #3e1e81 }
+(UIImage *)loadLogo{
//把图片封装到bundle里面
return [UIImage imageNamed:@"CZTools.bundle/logo.png"];
}
来到主控制器中使用
p.p1 { margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; color: #000000 }
span.s1 { color: #6122ae }
span.s2 { }
span.s3 { color: #3e1e81 }
span.s4 { color: #0435ff }
span.s5 { color: #703daa }
span.s6 { color: #3c828b }
span.s7 { color: #294c50 }
span.s8 { color: #c42275 }
UIImageView *imageView1 = [[UIImageView alloc]initWithFrame:CGRectMake(100, 100, 100, 100)];
imageView1.image = [LHQTools loadLogo];
[self.view addSubview:imageView1];
这个时候,运行程序,会显示这张图片
p.p1 { margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; color: #1e9421 }
span.s1 { color: #000000 }
span.s2 { }
span.s3 { font: 18.0px "PingFang SC" }
//3 封装视图
新建继承自UIView的类
定义类方法
p.p1 { margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; color: #c81b13 }
p.p2 { margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; color: #000000; min-height: 21.0px }

p.p4 { margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; color: #c42275 }
span.s1 { color: #822d0f }
span.s2 { }
span.s3 { color: #c42275 }
span.s4 { color: #6122ae }
span.s5 { color: #703daa }
