objective-c - 在 UILabel 中显示 NSTimer 计数

Question

我想显示加载进程的倒计时，并了解不允许将ARC其转换int为NSString. 我怎样才能显示我count的内NSString？

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

可能最简单的方法是：

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

Answer 2

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