在这个解决方案中,我假设您UILabel
至少有 2 行,并且\n
在第一行的末尾有一个字符。
UILabel *lbl = (UILabel *)[self.view viewWithTag:2];
NSString *firstString;
NSString *secondString;
NSRange foundRange = [lbl.text rangeOfString:@"\n"];
if (foundRange.location != NSNotFound)
{
foundRange.length = foundRange.location + 1;
foundRange.location = 0;
firstString = [[NSString alloc] initWithString:[lbl.text substringWithRange:foundRange]];
secondString = [[NSString alloc] initWithString:[lbl.text stringByReplacingCharactersInRange:foundRange withString:@""]];
NSLog(@"first line = %@", firstString);
NSLog(@"second line = %@", secondString);
[firstString release];
[secondString release];
}
