ps：當(dāng)你想讓Label的文字靠后绢要，但無法修改 Label 的內(nèi)邊距燕侠，你可以 修改 Label 的 段落樣式 達(dá)到想要的效果
UILabel * label = [[UILabel alloc]init];
// label.text = @"推薦用戶";
label.font = [UIFont jk_systemFontOfPxSize:28];
label.textColor = [UIColor colorWithHexString:@"#333333"];
label.backgroundColor = [UIColor whiteColor];
NSMutableParagraphStyle *paraStyle = [[NSMutableParagraphStyle alloc] init];
paraStyle.alignment = NSTextAlignmentLeft; //對齊
paraStyle.headIndent = 0.0f;//行首縮進(jìn)
//參數(shù)：（字體大小17號字乘以2闷愤，34f即首行空出兩個字符）
CGFloat emptylen = label.font.pointSize * 2;
paraStyle.firstLineHeadIndent = emptylen;//首行縮進(jìn)
paraStyle.tailIndent = 0.0f;//行尾縮進(jìn)
paraStyle.lineSpacing = 2.0f;//行間距
NSAttributedString *attrText = [[NSAttributedString alloc] initWithString:@"推薦用戶" attributes:@{NSParagraphStyleAttributeName:paraStyle}];
label.attributedText = attrText;
