-常用结构体
//1.创建一个NSRange结构体 表示范围
NSRange range = {4,5};
NSRange range2 = NSMakeRange(4, 5);
NSString * strRange = NSStringFromRange(range);
NSLog(@"strRange %@",strRange);
//2.NSSize 等同于 CGSize 有两个值组成 weight表示宽度 height高度
NSSize size = {21,19};
NSSize size2 = NSMakeSize(21, 19);
NSString *strSize = NSStringFromSize(size2);
NSLog(@"strSize %@",strSize);
//3.NSPoint 等同CGPoint 表示一个点的坐标位置
NSPoint point = {20,40};
NSPoint point2 = NSMakePoint(20, 40);
NSString * strPoint = NSStringFromPoint(point);
NSLog(@"strPoint %@",strPoint);
//4.NSRect
NSRect rect = {40,60,100,200};
NSRect rect2 = NSMakeRect(0, 10, 100, 100);
NSString * strRect = NSStringFromRect(rect);
NSLog(@"strRect %@",strRect);
