小编fay*_*yaz的帖子

我有涉及问题UILabel的sizeToFit方法:

UILabel *questionLabel = [[UILabel alloc]initWithFrame:CGRectMake(0,0,320,320)];
questionLabel.lineBreakMode = UILineBreakModeWordWrap;
questionLabel.backgroundColor=[UIColor clearColor];
questionLabel.textAlignment=UITextAlignmentLeft;
questionLabel.textColor=[UIColor blackColor];
questionLabel.tag=1;
questionLabel.font=[UIFont systemFontOfSize:13];
questionLabel.numberOfLines = 0;
[questionLabel sizeToFit];
[myView addSubview:questionLabel];

我写了这段代码来显示我的数据.但如果我写:[questionLabel sizeToFit]我的数据无法正常显示.如果我删除[questionLabel sizeToFit]它然后显示但它只显示一半的数据.

感谢致敬.
