Iphone – How to change the uitextview font size

font-sizeiphoneuitextviewxcode

can any one help to change the font size in UITextView.

[textView setFont:[UIFont fontWithName:@"ArialMT" size:30]];

I use this one but it doesn't work.

Have you bind textView with xib or allocated textView?

If yes,

You can use following code to check whether this works

[textView setFont:[UIFont boldSystemFontOfSize:15]];

 [textView setFont:[UIFont systemFontOfSize:15]];

Go to Targets in Xcode.
Build Settings on your project's target (your current development name).
Search for Product Name under Packaging. Change its value to what you want your new project name to be.

For iOS 7.0, I've found that the contentInset trick no longer works. This is the code I used to get rid of the margin/padding in iOS 7.

This brings the left edge of the text to the left edge of the container:

textView.textContainer.lineFragmentPadding = 0

This causes the top of the text to align with the top of the container:

textView.textContainerInset = .zero

Both lines are needed to completely remove the margin/padding.
