在UILabel中顯示NSTimer計數

Question

我想顯示我要加載的進程的倒計時，並瞭解它不允許使用ARC將int轉換爲NSString。如何在NSString內顯示我的count？

static int count = 0; 
count++; 

NSTimer *timer = [NSTimer scheduledTimerWithTimeInterval:(5.0) 
          target:self 
          selector:@selector(uploadData) 
          userInfo:nil 
          repeats:NO]; 

if (count <= 5) 
{ 
    ilabel.text = @"Please be patient..."; 
    NSString *counter = count; 
    counterLabel.text = counter; 
} 

Answer 1

可能做到這一點，最簡單的方法是：

NSString* counter = [NSString stringWithFormat: @"%d", count]; 

Answer 2

counterLabel.text = [NSString stringWithFormat:@"%d",count];
