oc中将CGRect、CGSize、CGPoint等结构体转换为字符串

CGRect rect = CGRectMake(160, 230, 200, 200);

CGPoint point = CGPointMake(20, 20);
CGSize size = CGSizeMake(20, 20);

NSString *str = NSStringFromCGRect(rect);
NSString *str1 = NSStringFromCGSize(size);
NSString *str3 = NSStringFromCGPoint(point);
NSMutableArray *array = [[NSMutableArrayalloc]initWithCapacity:0];
[array addObject:str];
[array addObject:str1];
[array addObject:str3];
CGRect rect1 = CGRectFromString(array[0]);
CGSize size1 = CGSizeFromString(array[1]);
CGPoint point1 = CGPointFromString(array[2]);

　　　需要往数组、字典中封装的时候、还可以转换成NSValue封装的。
