下面給出的實例就是markdown和Emoticon展示
一、YYText示例之markdown
下面直接看代碼
#import "YYTextMarkdownExample.h"
#import "YYText.h"
#import "YYImage.h"
#import "UIImage+YYWebImage.h"
#import "UIView+YYAdd.h"
#import "NSBundle+YYAdd.h"
#import "NSString+YYAdd.h"
#import "YYTextExampleHelper.h"
@interface YYTextMarkdownExample () <YYTextViewDelegate>
@property (nonatomic, strong) YYTextView *textView;
@end
@implementation YYTextMarkdownExample
#pragma mark - Override Base Function
- (void)viewDidLoad
{
[super viewDidLoad];
self.view.backgroundColor = [UIColor whiteColor];
if ([self respondsToSelector:@selector(setAutomaticallyAdjustsScrollViewInsets:)]) {
self.automaticallyAdjustsScrollViewInsets = NO;
}
NSString *text = @"#Markdown Editor\nThis is a simple markdown editor based on `YYTextView`.\n\n*********************************************\nIt\'s *italic* style.\n\nIt\'s also _italic_ style.\n\nIt\'s **bold** style.\n\nIt\'s ***italic and bold*** style.\n\nIt\'s __underline__ style.\n\nIt\'s ~~deleteline~~ style.\n\n\nHere is a link: [YYKit](https://github.com/ibireme/YYKit)\n\nHere is some code:\n\n\tif(a){\n\t\tif(b){\n\t\t\tif(c){\n\t\t\t\tprintf(\"haha\");\n\t\t\t}\n\t\t}\n\t}\n";
YYTextSimpleMarkdownParser *parser = [YYTextSimpleMarkdownParser new];
[parser setColorWithDarkTheme];
YYTextView *textView = [YYTextView new];
textView.text = text;
textView.font = [UIFont systemFontOfSize:14];
textView.textParser = parser;
textView.size = self.view.size;
textView.textContainerInset = UIEdgeInsetsMake(10, 10, 10, 10);
textView.delegate = self;
if (kiOS7Later) {
textView.keyboardDismissMode = UIScrollViewKeyboardDismissModeInteractive;
}
textView.backgroundColor = [UIColor colorWithWhite:0.134 alpha:1.000];
textView.contentInset = UIEdgeInsetsMake(64, 0, 0, 0);
textView.scrollIndicatorInsets = textView.contentInset;
textView.selectedRange = NSMakeRange(text.length, 0);
[self.view addSubview:textView];
self.textView = textView;
}
#pragma mark - Action && Notification
- (void)edit:(UIBarButtonItem *)item
{
if (_textView.isFirstResponder) {
[_textView resignFirstResponder];
}
else {
[_textView becomeFirstResponder];
}
}
#pragma mark - YYTextViewDelegate
- (void)textViewDidBeginEditing:(YYTextView *)textView
{
UIBarButtonItem *buttonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone
target:self
action:@selector(edit:)];
self.navigationItem.rightBarButtonItem = buttonItem;
}

YYTextView *textView = [YYTextView new];
textView.text = @"Hahahah:smile:, it\'s emoticons::cool::arrow::cry::wink:\n\nYou can input \":\" + \"smile\" + \":\" to display smile emoticon, or you can copy and paste these emoticons.\n";
textView.font = [UIFont systemFontOfSize:17];
textView.textParser = parser;
textView.size = self.view.size;
textView.linePositionModifier = mod;
textView.textContainerInset = UIEdgeInsetsMake(10, 10, 10, 10);
textView.delegate = self;
if (kiOS7Later) {

}
textView.contentInset = UIEdgeInsetsMake(64, 0, 0, 0);
textView.scrollIndicatorInsets = textView.contentInset;
[self.view addSubview:textView];
self.textView = textView;
[self.textView becomeFirstResponder];
}
