Answer 1

why dont you use NSMutableAttributedString for this with one LABEL.
NSString *text1 = #"Hello";
NSString *date1 = #" 12.05 Pm\n";
NSString *text2 = #"World";
NSString *date2 = #" 11.00 AM";
self.lbl.numberOfLines = 0;
NSString * str = [text1 stringByAppendingString:date1];
NSString * str2 = [text2 stringByAppendingString:date2];
UIFont *text1Font = [UIFont fontWithName:#"HelveticaNeue-Medium" size:10];
NSMutableAttributedString *attributedString1 = [[NSMutableAttributedString alloc] initWithString: str attributes:#{ NSFontAttributeName : text1Font }];
NSMutableParagraphStyle *paragraphStyle1 = [[NSMutableParagraphStyle alloc] init];
[paragraphStyle1 setAlignment: NSTextAlignmentLeft];
[paragraphStyle1 setLineSpacing:1];
[attributedString1 addAttribute:NSParagraphStyleAttributeName value: paragraphStyle1 range:NSMakeRange(0, [attributedString1 length])];
UIFont *text2Font = [UIFont fontWithName:#"HelveticaNeue-Medium" size:10];
NSMutableAttributedString *attributedString2 = [[NSMutableAttributedString alloc] initWithString: str2 attributes:#{NSFontAttributeName : text2Font }];
NSMutableParagraphStyle *paragraphStyle2 = [[NSMutableParagraphStyle alloc] init];
[paragraphStyle2 setLineSpacing:1];
[paragraphStyle2 setAlignment: NSTextAlignmentLeft];
[attributedString2 addAttribute:NSParagraphStyleAttributeName value: paragraphStyle2 range:NSMakeRange(0, [attributedString2 length])];
[attributedString1 appendAttributedString:attributedString2];
[self.lbl setAttributedText:attributedString1];

Answer 2

because above label is overlap on bottom label like above image so you not display that if you see that label above label x position change then it display.
if x value set 50 then you display bottm label.

Answer 3

You are adding aboveLabel as subview of bottomLabel hence it doesnot get displayed when you assign chinese character to it. You can see it view hierarchy as it is assigned a frame and added as subview. If you want to add one UILabel above UILabel you can add both labels as subview of common parent view.
i.e.
[self.view addSubview:bottomLabel];
[self.view addSubview:aboveLabel];

Answer 4

You are trying to adding aboveLabel inside of bottomLabel.Instead add both into one view or self.view.

Answer 5

UILabel *bottomLabel = [[UILabel alloc]initWithFrame:CGRectMake(0, 100, 200, 40)];
bottomLabel.backgroundColor = [UIColor redColor];
bottomLabel.text = #"中文";
[self.view addSubview:bottomLabel];
UILabel *aboveLabel = [[UILabel alloc]initWithFrame:CGRectMake(0, CGRectGetMaxY(bottomLabel.frame)+10, 60, 30)];
aboveLabel.backgroundColor = [UIColor greenColor];
aboveLabel.text = #"aboveLabel";
[self.view addSubview:aboveLabel];

Answer 6

Try this code
Objective - C
UILabel *bottomLabel = [[UILabel alloc]initWithFrame:CGRectMake(0, 0, 200, 30)];
bottomLabel.backgroundColor = [UIColor redColor];
bottomLabel.text = #"中文";
[self.view addSubview:bottomLabel];
UILabel *aboveLabel = [[UILabel alloc]initWithFrame:CGRectMake(50, 0, 60, 30)];
aboveLabel.backgroundColor = [UIColor greenColor];
aboveLabel.text = #"abc";
[bottomLabel addSubview:aboveLabel];
