NSString * content = @"測試高度";
CGSize _textLabelSize ?= [content boundingRectWithSize:CGSizeMake(ScreenWidth-20, MAXFLOAT) options:NSStringDrawingUsesLineFragmentOrigin|NSStringDrawingUsesFontLeading attributes:@{NSFontAttributeName:[UIFont boldSystemFontOfSize:14]} context:nil].size;
枚舉要設(shè)置兩個(gè) NSStringDrawingUsesLineFragmentOrigin | NSStringDrawingUsesFontLeading 可以解決有時(shí)高度不準(zhǔn)的問題。
