使用NSMutableParagraphStyle和NSAttributeString類
NSMutableParagraphStyle*style = [[NSParagraphStyle defaultParagraphStyle] mutableCopy];
//對齊方式
style.alignment = NSTextAlignmentLeft;
//首行縮進
style.firstLineHeadIndent=40.0f;
NSAttributedString*attrText = [[NSAttributedString alloc] initWithString:@"shibushisssssss我們就是shibushisssssss我們就是11111111" attributes:@{NSParagraphStyleAttributeName: style}];
self.contentlabel.numberOfLines =0;
self.contentlabel.attributedText = attrText;
運行效果:
UILabel首行縮進
