问题 I want to add an image in start of UILabel. Label is multiline. If I use contentInset, it indent the whole label but I want to indent first line only.

UIEdgeInsets titleInsets = UIEdgeInsetsMake(0.0, 40.0, 0.0, 0.0); valueLabel.contentInset = titleInsets; It should look like this. 回答1: @DavidCaunt suggestion worked for me. I am sharing code here. NSMutableParagraphStyle *style = [[NSMutableParagraphStyle alloc] init]; style

问题 How the UILabel can be aligned from bottom. Let say, my label can hold three line of text.If the input text is single line, then this line should come bottom of the label.Please refer the below image for better understanding. The orange area is the full frame of label.Currently it has one line and it is aligned center. So what I want is, it should always aligned bottom regardless of how many lines.

问题 I know that for elements of classes UIButton and UIBarButtonItem they automatically assume window.tintColor as the main colour, which results of an immediate change in case I set a new tintColor to window at any time in the app. I was wondering if there is any way to make UILabel elements to follow the same pattern, where once created they automatically assumer its default colour as window.tintColor and if changing window.tintColor at any time within my app runtime would also result in

问题 I'm making a program that 's about a math test random generator. But while I was creating a random operation. I used arc4random_uniform() to create a random number.

问题 I have an app, which is intended only for iPad in landscape mode. The screen design is completely done in IB with autolayout. Now I want to achieve the following behaviour: All the labels should have font size 48 when on iPad Pro 12", and for all smaller iPad sizes the font size should be 32. I tried various options in IB with autoshrink and minimum font size, but then the app picks font sizes in between 48 - 32 and gives a random look. But I only want to have 48 for 12" or 32 for all smaller

问题 Correct me if I'm wrong, but when I try to update my label in a while loop it won't update it. Is the reason that the while loop runs too quickly for the label to update within that time so it'll cancel the label from updating? I need a solution to this?
