I want to make one empty array using for loop, and for this I wrote below code, but it displays array elements like 1,2,3,4,5 in NSLog statements, but I want to display empty array like ("","","","","")
Here is my code:
arrTemp=[[NSMutableArray alloc]init];
for (int i = 0; i < 5; i++) {
[arrTemp addObject:[NSString stringWithFormat:@"%d",i]];
}
NSLog(@"array detais is %@",arrTemp);
Just use the following:
[arrTemp addObject:@""];
In swift you can do the same in one line of code:
var arrTemp = Array(count: 5, repeatedValue: "")
A perfectly correct answer has been provided by Alessandro. However, I think understanding why your solution did not provide the required result would be beneficial to your learning.
In the line: [arrTemp addObject:[NSString stringWithFormat:@"%d",i]];
you are adding a string with the %d format, which indicates an integer. The integer is being provided by your loop: for (int i = 0; i < 5; i++) the first item added is a 0, then a 1,..4; By using empty quotes, you have the solution you are looking for.
[arrTemp addObject:[NSString stringWithFormat:@""]];
You are not using any formatter with your string, so the statement can be simplified into the answer provided by Alessandro
-:[arrTemp addObject:@""];
