簡單數組循環問題Objective-C

Question

如何完成這項工作？

numbers = [[NSMutableArray alloc] initWithObjects: ({int x = 0; while (x <= 60) { return x; x++; } })]; 

謝謝:)

Answer 1

NSMutableArray * array = [[NSMutableArray alloc] init]; 

for (int i = 0; i <= 60; ++i) { 
    [array addObject:[NSNumber numberWithInt:i]]; 
} 

Answer 2

int myStrangeNumberOfItems = 61; 

NSMutableArray * numbers = [[NSMutableArray alloc] initWithCapacity: myStrangeNumberOfItems]; 
for (int i = 0; i < myStrangeNumberOfItems; i++) { 
    [numbers addObject:[NSNumber numberWithInt:i]]; 
} 

Answer 3

首先，一個NSArray只能容納對象，而不是原語。您可以像這樣在for循環中添加對象。

NSMutableAray * numbers = [[NSMutableArray alloc] init]; 
for (int x = 0; x <= 60; x++) 
    [numbers addObject:[NSNumber numberForInt:x]];
