一却特、YYText示例
下面看這個示例
#import "YYTextTagExample.h"
#import "YYText.h"
#import "UIView+YYAdd.h"
#import "YYTextExampleHelper.h"
@interface YYTextTagExample () <YYTextViewDelegate>
@property (nonatomic, assign) YYTextView *textView;
@end
@implementation YYTextTagExample

} else {

}

textView.selectedRange = NSMakeRange(text.length, 0);
[self.view addSubview:textView];
self.textView = textView;
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.6 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{

});
}
