limit the UILabel to 500 character and than Truncate the UIlabel in IOS

ios, ios5, iphone, uilabel

Solution

Just truncate the string if it's longer than 500 characters. Only caveat: make sure to not break it in the middle of a surrogate pair:

NSString *temp = [galleryEntryTree objectForKey:@"description"];
if ([temp length] > 500) {
    NSRange range = [temp rangeOfComposedCharacterSequencesForRange:(NSRange){0, 500}];
    temp = [temp substringWithRange:range];
    temp = [temp stringByAppendingString:@" …"];
}
coverView.label2.text = temp;

Problem

I want to display first 500 character in UILabel and than display Truncate icon if there is more than 500 character available.But i dont know how can i limit 500 character to truncate the text?. Here is my code ``` label2 = [[UILabel alloc] initWithFrame:CGRectMake(0, 350, self.bounds.size.width, 30)]; // In this case value of self.bounds.size.width is "427" label2.backgroundColor = [UIColor clearColor]; label2.numberOfLines = 2; label2.textAlignment = UITextAlignmentCenter; label2.font = [UIFont systemFontOfSize:13]; [self addSubview:label2] //Here is Implimentation code of my label NSString *temp = [galleryEntryTree objectForKey:@"description"];// calling lebel text from database coverView.label2.text = temp; coverView.label2.adjustsFontSizeToFitWidth = NO; coverView.label2.lineBreakMode = UILineBreakModeTailTruncation; ``` Just tell me guys how can i display min 500 character and than truncate it( if longer than 500) Any help is appreciated
