ios - 将 1299 显示为 1.2K 而不是 1.3K

Question

我的号码是 1299。

我要显示为1.2K

我在下面试过，但它给出的是 1.3K

int mLike 
NSString *mString = [NSString stringWithFormat:@"%d", mLike];
if (mLike>=1000) {
    mString = [NSString stringWithFormat:@"%0.1fK", mLike*1.0/1000];
}
mString = [mString stringByReplacingOccurrencesOfString:@".0" withString:@""];
likeLabel.text = [NSString stringWithFormat:@"%@ LIKES", mString];

这给了我 1.3 K

知道如何将它设置为 1.2K 吗？

Answer 1

NSInteger mLike = 1301;
NSString *mString = [NSString stringWithFormat:@"%d", mLike];
if (mLike>=1000) 
{
    mLike = mLike - (mLike%100); // this was missing in your code. Subtract the remainder from the total inorder to get the desired result.
    mString = [NSString stringWithFormat:@"%0.1fK", mLike*1.0/1000];
}
mString = [mString stringByReplacingOccurrencesOfString:@".0" withString:@""];
NSLog(@"%@",[NSString stringWithFormat:@"%@ LIKES", mString]);
