Xcode中的字符串格式

Question

以下將返回「14.00」，「16.00」等數據。我想在表格單元上顯示它爲$ 14 $ 16

謝謝。

cell.lbl_Rental_Fee.text = [[self.responseData_In_Array objectAtIndex:indexPath.row] objectForKey:@"Rental_Fee_Hour"]; 

Answer 1

你會想是這樣假設你的價值是float

NSString *thing = [NSString stringWithFormat:@"$%.0f", yourValue]; 

所以在你的例子：

NSString *response = [[self.responseData_In_Array objectAtIndex:indexPath.row] objectForKey:@"Rental_Fee_Hour"]; 
float yourValue = [response floatValue]; 
cell.lbl_Rental_Fee.text = [NSString stringWithFormat:@"$%.0f", yourValue];
