1.跳轉到應用商店下載的兩種方式：
NSString *str=@"https://itunes.apple.com/cn/app/appName/idappID";
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:str]];
appname可以填可不填 appid是自己Itunes上創建應用時的APPID
NSString *str=@"https://itunes.apple.com/cn/app/he-mu-jing-ying-ban/id929523252";
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:str]];
2.textField長度限制關於中文聯想詞崩潰的， 添加[textField markedTextRange]==nil判斷
if ([textField markedTextRange]==nil) {
if (text.length > _max) {
text = [text substringToIndex: _max];
}
return text;
}
3.瘋轉了數字顯示轉換的
-(void)setShows:(UIButton *)button withCount:(NSInteger)count{
if(count==0){
[button setTitle:@"評論" forState:UIControlStateNormal];
}else if(count<10000){
[button setTitle:[NSString stringWithFormat:@"%d",count] forState:UIControlStateNormal];
}else{//大於10000顯示1.2萬
CGFloat number=count/10000.0f;
NSString *title=[NSString stringWithFormat:@"%.1f萬",number];
title=[title stringByReplacingOccurrencesOfString:@".0" withString:@""];
[button setTitle:title forState:UIControlStateNormal];
}
}
4.關於時間顯示的：
+(NSString *)formatterSinaDateToBeforeTime:(NSString *)dateString{
NSDateFormatter *dateFormatter=[[NSDateFormatter alloc] init];
//1.設置新浪微博的時間的日期格式 獲取新浪API的時間戳
dateFormatter.dateFormat=@"EEE MMM d HH:mm:ss Z yyyy";
//必須設置locale，否則無法解析
dateFormatter.locale=[[NSLocale alloc]initWithLocaleIdentifier:@"en_US"];
// dateFormatter.dateFormat=@"EEE MMM d HH:mm:ss zzzz yyyy";
//2.獲取格式化後的日期
NSDate *date=[dateFormatter dateFromString:dateString];
//3.獲取當前時間
NSDate *now=[NSDate date];
//4.獲取當前時間與格式化後的日期的時間差
NSTimeInterval sinceDate=[now timeIntervalSinceDate:date];
//5.判斷時間差該顯示的內容
// NSString *timeDescription;
if (sinceDate<60) {//1分鐘以內
return @"剛剛";
}else if (sinceDate<60*60){//1消失以內
return [NSString stringWithFormat:@"%.f分鐘前",sinceDate/60];
}else if (sinceDate<60*60*24){//一天以內
return [NSString stringWithFormat:@"%.f小時前",sinceDate/60/60];
}else{
dateFormatter.dateFormat=@"MM-dd HH:mm";
return [dateFormatter stringFromDate:date];
}
}
