Cómo almacenar los valores de CGRect en NSMutableArray?

Question

¿Cómo puedo almacenar objetos CGRect en un NSMutableArray y luego recuperarlos?

Answer 1

Debe envolver las estructuras CG en las clases NSValue. Por lo tanto:

NSMutableArray* array = [NSMutableArray mutableArray]; 
[array addObject:[NSValue valueWithCGRect:CGRectMake(0,0,10,10)]]; 
CGRect someRect = [[array objectAtIndex:0] CGRectValue]; 

Answer 2

CGRect rect = CGRectMake(5, 5, 40, 30); 
NSString* rectAsString = NSStringFromCGRect(rect); 
CGRect original = CGRectFromString(rectAsString); 

¿Qué opinas acerca de esta forma de almacenar fechas CGRect?

Answer 3

Store string in array.and then get back string and convert that in CGRect back as per the need. 
CGRect rect = CGRectMake(5, 5, 40, 30); 
NSString* rectAsString = NSStringFromCGRect(rect); 
NSMutableArray* array = [NSMutableArray mutableArray]; 
[array addObject:rectAsString]; 

For converting string in CGRect back use:- 
CGRect rect9 = CGRectFromString(rectAsString); 

Answer 4

almacenamos la CGRect, CGPoint, CMTime objetos en un NSMutableArray,

[arrayName addObject:[NSValue valueWithCGPoint:MyCGPoint]]

[arrayName addObject:[NSValue valueWithCGRect:MyCGRect]]

[arrayName addObject:[NSValue valueWithCMTime:MyCMTime]]

[arrayName addObject:[NSValue valueWithCMTimeRange:MyCMTimeRange]]
